DO NOT COMPLETE ALL SECTIONS OF THE QUESTIONNABRE. The
following explains which sections you should complete based on the type of making
holes conductive (MHC) process used at your facility, provides background
information on the questionnaire, and describes how the data will be handled to
ensure confidentiality.

1.     This questionnaire was prepared by the University of Tennessee Center for Clean
      Products and Clean Technologies in partnership with the EPA DfE Program, IPC, PWB
      manufacturers, and other members of the DfE PWB Industry Project.

2.     For the purposes of this survey and the DfE Project, the "Making Holes Conductive
      (MHC)" process is defined as beginning after the desmear and etchback steps and ending
      prior to the dry film resist outer layer step (if required) and copper electroplating step.

3.     Shaded sections of the questionnaire denote areas where responses to questions should be
      entered. Unshaded sections are instructions or keys required to answer the question.

4.     Throughout the questionnaire, many questions request specific data, such as chemical
      volumes, the amount of water consumed by the MHC line or the characteristics of
      wastewater from the MHC line. If specific data are not readily available, estimates based
      on your knowledge of the process and the facility, are adequate. In cases where no data
      are available and there is no basis for an accurate estimate, mark your response as "ND."

5.     Please complete  Sections 1 through  3 of the questionnaire, regardless of which process is
      used at your facility to make drilled through-holes conductive prior to electroplating.

6.     After completing Sections 1 through 3, please complete only the section(s) of the survey
      that corresponds to the MHC processes) currently being operated at your facility, as
      listed below.

             remainder of the form.  Place the facility and contact information into Envelope #
             1 and seal the envelope.
       (3)    Place the remainder of the survey form plus any additional sheets or exposure
             monitoring data into Envelope # 2 and seal it.
       (4)    Place sealed envelopes # 1  and # 2 into the larger return envelope and mail it to
             IPC.
       (5)    When the package is received by IPC, only Envelope # 1 will be opened. IPC
             will place a code number on the outside of Envelope # 2 and forward it to the
             Center for Clean Products and Clean Technologies at the University of Tennessee.
             Envelope #  1 will not be sent to the University of Tennessee.
       (6)    Questions, clarifications, or requests for further information from the University
             of Tennessee will be relayed by code number to IPC, who will be able to contact
             the respondent. When it is determined that no further communications with
             respondents are necessary, the matrix of code numbers and respondents will be
             destroyed by IPC.

 'rocess History:
in Part A, Question 3.4, the facility recorded their reason(s) for changing to their current system.
    Have they realized this benefit to a greater or lesser extent than expected? Explain and obtain
    (attach) quantitative information if not given in Part A.


I Were any changes made when the line was installed that were not part of the system or were optional
(e.g., flow control valves added to water rinses? cascaded water rinses? etc.)? Explain:
Product Quality:
What, if any, changes were noticed in the quality of the boards produced?
     of Use:
Does the current process require more or less effort than the previous process and why (e.g., chemica
bath replacement, process steps or activities created or eliminated, such as rack loading, etc.)?
Does this process require more "fine tuning" than the previous process? (e.g., can it handle a range of
operating concentrations, such as bath temperature variations? does it need more frequent chemical
additions or monitoring? etc.).  Explain:
 Installation:
  tow long was the debug period when this system was installed?

   lat were the types of problems encountered?
 low does this compare with the previous system installation?
     ufacturing Process Changes: How did you change your upstream or downstream processes
  'hen this system was installed? (e.g., did you change your desmear? did you have to make changes in
 your electrolytic line?)
 Personnel: Do you need the same number of operators to operate the current line as your previous
  ic?  [Verify that any changes were not caused by a change in throughput].
                                                                                        DRAFT

  Waste Treatment:
  Have any of your waste treatment methods or volumes changed due to the installation of this system
  (not associated with volume changes due to throughput changes)?
      If yes, describe the change(s) and attach quantitative information, if available:
  Process Safety:
      Have any additional OSHA-related procedures or issues arisen as a result of changing to the
      present system (e.g., machinery lock-outs while cleaning, etc.)? If so, describe:
 international Sites
 For international sites only, do any bans or phase-outs of chemicals affect your choice of chemicals
 or technologies used in the MHC process? (e.g., Quadrol or EDTA ban)
 For international sites only, what is the regulatory atmosphere in the country and what effects does ii
 have on the MHC process? Are applicable regulations local, regional, or national?

 Fill in the table below by identifying what type of making holes conductive process (e.g.,  electroless
 copper)  your facility uses.  Then, using the key at the bottom left of the page, identify which letter
 corresponds with the first bath step in your process and write that letter in the first box (see example).
 Continue using the  key to fill in boxes for each step in your process until your  entire making holes
 conductive process is represented.  If your process step is not represented by the key  below, complete the
 chart by writing in the name of the process step in your particular making holes conductive line.  Finally,
 consult the process automation key at bottom right  and enter the appropriate  type of automation for the
 MHC process line.  If the process is partially automated, enter the appropriate process automation letter
 for each step in the upper right-hand corner box  (see example).

H.  ENVIRONMENTAL FATE

    A.  Environmental Release
        1,3-Benzenediol may be released into the environment in waste effluents associated with coal
        gassification and conversion, coal-tar production, shale oil processing, and from the combustion
        of wood and tobacco (HSDB 1995).  1,3-Benzenediol is found in cigarette smoke (HSDB 1995).
                                                                                               DRAFT

-------
APPENDIX C
       1,3-Benzenediol is not one of the chemicals reported to the Toxics Release Inventory (TRI) by
       certain types of U.S. industries.

    B.  Transport
       1,3-Benzenediol is expected to leach readily in soil; however, leaching may not be important if
       concurrent biodegradation occurs at a rapid rate (HSDB 1995).

    C.  Transformation/Persistence
       1.   Air — If released to the atmosphere, 1,3-benzenediol can be expected to exist almost
            entirely in the gas-phase in the ambient atmosphere. Gas-phase 1,3-benzenediol is expected
            to degrade rapidly in air (estimated half-life 1.9 hours) by reaction with photochemically
            produced hydroxyl radicals. Night-time reaction with nitrate radicals may also contribute to
            atmospheric transformation (HSDB 1995).
       2.   Soil — 1,3-Benzenediol is readily degradable in soil. The degradation rate decreases at low
            temperatures (CHEMFATE 1995).
       3.   Water— 1,3-Benzenediol is confirmed to be significantly degradable in water
            (CHEMFATE 1995). By analogy to other phenol compounds, 1,3-benzenediol may react
            relatively rapidly in sunlit natural water with photochemically produced oxidants such as
            hydroxyl and peroxyl radicals (HSDB 1995). Hydrolysis, volatilization, and adsorption to
            sediments are not expected to be important (HSDB 1995).
       4.   Biota — Bioconcentration of 1,3-benzenediol is not expected to be important (HSDB
            1995).

H.  ENVIRONMENTAL FATE

    A.  Environmental Release
        No information was found in the secondary sources searched regarding the environmental release
        of IH-pyrrole. IH-pyrrole is one of a group of compounds containing five-membered rings with
        one or more nitrogen atoms (Trochimowicz et al. 1994). The industrial use of the simpler
        members of this group of chemicals is limited (Trochimowicz et al. 1994). IH-pyrrole may be
        released to the environment from plants that manufacture it or use it either as a chemical
        intermediate in the production of drugs, dyes, herbicides, and perfumes, or as a cross-linking
        agent for resins (HSDB 1996). However, its limited use would likely preclude the release of
        large volumes  of the chemical to the environment.  IH-pyrrole occurs naturally as part of the
                                                                                           DRAFT

       structure of pigments such as bilirubin and herae and is a constituent of coal tar and bone oil
       (Trochimowicz et al. 1994).

    B. Transport
       No information was found in the secondary sources searched regarding the environmental
       transport of IH-pyrrole.  The vapor pressure (1100-1136 Pa [Mackay et al. 1995]) and the
       Henry's Law Constant (1.6 x 10'5 atm-mVmol) of the chemical indicate that some volatilization
       from soil or water could occur. IH-pyrrole is slightly soluble in water and small amounts may
       move through the soil, possibly to groundwater.

    C. Transformation/Persistence
       1.   Air — IH-pyrrole in air would undergo  oxidation, probably within hours. For gas-phase
            reaction at room temperature the rate constant has been estimated at 1.2 x 10"10 cm3
            molecule'1 sec'1, assuming the concentration of OH radicals to be 1 x 106/cm3 during the
            daytime. This value corresponds to a calculated lifetime of 2.3 hours (Mackay et al. 1995).
            In other studies, the calculated lifetime was 1.4 minutes for reaction with NO3 radicals
            during nighttime hours and 24 hours for reaction with O3 molecules (Mackay et al. 1995).
       2.   Soil—No information was found in the secondary sources searched regarding the
            degradation of IH-pyrrole in the soil.
       3.   Water — No information was found in the secondary sources searched regarding the
            degradation of IH-pyrrole in water.
       4.   Biota — The log Kow for IH-pyrrole (0.75 [Mackay et al.  1995]) indicates that the chemical
            has a low to moderate potential to  bioaccumulate in aquatic organisms.

    A.  Environmental Release
        2-Butoxyethanol acetate may be released to the atmosphere by evaporation when it is used as a
        solvent in paints, lacquers, thinners, inks, and resins. The emission rate into the atmosphere
        from painting operations in an automobile assembly plant in Wisconsin was estimated at 37.9
        gallons/hour (Howard 1993). 2-Butoxyethanol acetate was detected in 0.4% of 275 solvent
        products that were sampled in various industries and analyzed between  1978 and 1982 (HSDB
        1996).

        In 1993, releases of all glycol ethers to environmental media, as reported in the TRI by certain
        types of industries, totaled about 45.9 million pounds; 2-butoxyethanol acetate is not listed
        separately (TRI93 1995).

-------
 APPENDIX C
    B.  Transport
        The estimated relatively low KQC of 26 suggests that 2-butoxyethanol acetate can leach readily
        into groundwater from soils. However, if rapid biodegradation occurs, leaching may be less
        important. Volatilization from water is expected to be slow, with the possible exception from
        very shallow rivers. Physical removal via wet deposition is likely because the chemical is
        soluble in water (Howard 1993; HSDB 1996).

    C.  Transformation/Persistence
        1.   Air — Based on a vapor pressure of 0.375 mm Hg at 20°C, 2-butoxyethanol acetate should
            exist almost entirely in the vapor phase in the atmosphere.  It is expected that 2-
            butoxyethanol acetate will degrade by reaction with hydroxyl radicals with an estimated
            half-life of about 18.4 hours (HSDB 1996).
        2.   Soil — When released to soils, biodegradation is expected to be the most important removal
            process. One biodegradation screening study demonstrated that the chemical is readily
            (>90%) biodegraded (HSDB 1996).
        3.   Water — Biodegradation is likely to be the most important removal mechanism of 2-
            butoxyethanol acetate from aquatic systems. In a screening assay, 2-butoxyethanol acetate
            total degradation exceeded 90%, with a measured rate of 12%/day under the test conditions.
            No observable lag period was required before onset of degradation. Estimated
            volatilization half-lives from a model river (1 meter deep) and model pond are 6.6 and 74
            days, respectively.  Adsorption to  sediment is not expected to be important (HSDB 1996).
        4.   Biota — The estimated bioconcentration factor of 3.2 suggests that 2-butoxyethanol acetate
            would not bioconcentrate significantly in aquatic organisms (Howard 1993).

H.  ENVIRONMENTAL FATE

    A.  Environmental Release
        Environmental release of 2-ethoxyethanol can occur from wastewater effluents and atmospheric
        emissions from production and use facilities. Information on the amount of 2-ethoxyethanol
        released to the environment was not found in the secondary sources searched. Chemical
        concentrations detected in the Hayashida River (Japan) were 250-1200 ppb (Howard 1990; U.S.
        EPA 1985a).  Effluent from a facility in Brandenburg, KY contained 0.10 ug/L in 1974 (U.S.
        EPA 1985a).
                                                                                              DRAFT

-------
APPENDIX C
    B. Transport
       The Henry's Law constant of 5.13 x 10"2 atm-m3/mol (Howard 1990) indicates rapid
       volatilization from soils and surface waters. The complete water solubility and low Koc indicate
       that leaching from soils into ground water may occur.

    C. Transformation/Persistence
       1.   Air — In the atmosphere, 2-ethoxyethanol will react with both nitrogen oxides and
            hydroxyl radicals. The half-life of the chemical was 9.8 hour when mixed with nitrogen
            oxides (20:1,2-ethoxyethanol:nitrogen dioxides) in a smog chamber. For reaction with
            photochemically produced hydroxy radicals, the estimated half-life is 11.41 hours (Howard
            1990).
       2.   Soil — Volatilization and biodegradation are the main removal mechanisms for 2-
            ethoxyethanol from soils. Adsorption is not expected to be significant, so leaching into
            ground waters may occur (Howard 1990). A soil microbe acclimated to triethylene glycol
            was capable of utilizing 2-ethoxyethanol as a sole carbon source. In a standard evaporation
            test at 77°C and 15% relative humidity, 100% loss of the chemical occurred in 20 minutes
            (U.S. EPA 1985a).
       3.   Water — 2-Ethoxyethanol will volatilize readily from surface waters with biodegradation
            also contributing to removal. After incubation of the chemical for 5 days with either
            sewage seed or activated sludge, 7.6% and up to 65%, respectively, of the theoretical
            biological oxygen demand was achieved. Adsorption to suspended particulates and
            sediments is not expected to occur (Howard 1990).  Hydrolysis of 2-ethoxyethanol is not
            expected to be important (U.S. EPA  1985a).
       4.   Biota — Based on the complete water solubility and low Kow of 2-ethoxyethanol, the
            chemical is not expected to accumulate in aquatic organisms (U.S. EPA 1985a).

II.  ENVIRONMENTAL FATE

    A.  Environmental Release
        Ammonia is an important component of the nitrogen cycle such that concentrations in nature and
        natural media are in dynamic equilibrium (ATSDR 1990a). Natural sources of ammonia include
        volcanic eruptions, forest fires, microbial fixation of nitrogen, microbial decomposition of dead
        plants and animals, and decay of livestock, pet, and human wastes (ATSDR 1990a).
        Approximately 80% of the ammonia produced in the U.S. is applied to soils as fertilizer
        (ATSDR 1990a).
                                                                                              DRAFT
                                                 C-9

-------
APPENDIX C
       Average concentrations have been measured at <0.18 mg/L in surface waters and approximately
       0.5 mg/L in waters near metropolitan areas; concentrations were lower in the summer than in the
       winter (U.S. EPA 198la). Average global atmospheric ammonia concentrations are 1-3 ppb
       (ATSDR 1990a).

       In 1993, as reported to the TRI, a total of 353 million pounds of ammonia were released to the
       environment. Of the total, 138 million pounds were released to the atmosphere, 36 million
       pounds were released surface waters, 169 million pounds were released to underground injection
       sites, and 10 million pounds were released to land (TRI93 1995).

    B. Transport
       As a key component of the nitrogen cycle, ammonia in water and soils undergoes microbial
       mediated nitrification. The resulting nitrates are assimilated into plants and other microbes.
       This process is dependent upon dissolved oxygen, temperature, pH, the microbial population,
       and the nitrogen forms present (U.S. EPA 1981a; ATSDR 1990a). From natural waters,
       ammonia also volatilizes to the atmosphere or strongly adsorbs to sediment so that leaching is
       not likely (U.S. EPA  198la). Once in the atmosphere, the chemical can be removed in rain or
       snow or dissolve in clouds (ATSDR 1990a).

    C. Transformation/Persistence
       1.   Air — In the atmosphere, ammonia reacts with acid air pollutants such as HNO3 and H2SO4
            to form participate ammonium compounds that can be removed by wet or dry deposition
            (ATSDR 1990a). In unpolluted air, the half-life for ammonia reaction with hydroxyl
            radicals is about 16 days (U.S. EPA 1981a).
       2.   Soil — In soils, ammonia is transformed to nitrate by soil microbes and taken up by plants
            as a nutrient source. The ammonium cation adsorbs to negatively charged clay colloids in
            soils and is relatively immobile. Volatilization is another removal mechanism from soil
            (ATSDR 1990a; U.S. EPA 1981a).
       3.   Water — In natural waters, ammonia undergoes nitrification with the products being taken
            up by aquatic plants or other organisms. Ammonia can also adsorb to sediments or
            volatilize to the atmosphere (ATSDR 1990a; U.S. EPA 198la).
       4.   Biota — Ammonia is a natural waste product of fish and is released to the surrounding
            water through the gills. If water concentrations are abnormally high, the concentration
            gradient is reversed and the direction of passive transport is into the gills (ATSDR 1990a).

H. ENVIRONMENTAL FATE

    A.  Environmental Release
        Ammonium chloride, a somewhat hygroscopic crystalline solid with a cooling saline taste,  is
        highly soluble in water (Budavari et al. 1989). It is used in dry batteries; soldering; manufacture
        of various ammonia compounds; as a fertilizer; in electroplating; in medicine; and in the food
        industry (ACGIH 1991; Verschueren 1983). Large amounts of ammonium chloride are
        frequently evolved from galvanizing operations, with concentrations generally below 5 mg/m3,
        although peak concentrations are higher (ACGIH 1991). Ammonium chloride occurs naturally
        in crevices in the vicinity of volcanoes (Young 1978).

    B.  Transport
        No information on the transport of ammonium chloride was found in the secondary sources
        searched. The water solubility suggests that the chemical would leach through soil.
                                                                                              DRAFT

H.  ENVIRONMENTAL FATE

    A.  Environmental Release
        Benzotriazole may be released to the environment during its production and its use in a wide
        range of commercial products. Uses of the chemical include:  as a chemical intermediate; as a
        pickling inhibitor in boiler scale removal; as a restrainer, developer and antifogging agent in
        photographic emulsions; as a corrosion inhibitor for copper; as a component of military deicing
        fluid; and as a plastics stabilizer (HSDB  1995).  The NCI (1977) selected the chemical for study
        in the bioassay program because of its use in dishwashing detergents and the possibility that such
        use could result in the contamination of water supplies.

    B.  Transport
        The considerable water solubility of benzotriazole (19.8 g/L [CHEMFATE 1995]) suggests that
        the chemical may exist in solution in the soil and leach into ground water.  The low vapor
        pressure (0.04 Torr at 20°C [CHEMFATE 1995]) indicates that volatilization is not a significant
                                                                                             DRAFT

APPENDIX C
       transport mechanism for benzotriazole in soil or water.  In one instance, benzotriazole
       evaporated from water in 438 hours (-18 days) (CHEMFATE 1995). Because of its water
       solubility, benzotriazole present in the atmosphere may be removed by wet deposition.

    C. Transformation/Persistence
       1.   Air—No information was found in the secondary sources searched regarding the
            transformation/persistence of benzotriazole in air.  The considerable water solubility of
            benzotriazole (see section II.B) suggests that the chemical would be removed from the
            atmosphere by wet deposition.
       2.   Soil — The sensitivity of benzotriazole to photodegradation is solvent-dependent
            (CHEMFATE 1995).  The chemical was 100% degraded when irradiated for 60 hours at
            300 nm in methanol (CHEMFATE 1995). The products of degradation (also solvent-
            dependent) were aniline (1-1.6%) and O-anisidine (2-8.2%).
       3.   Water — In one study, benzotriazole as the sole source of carbon was not degraded by
            acclimated sludge in water (CHEMFATE 1995).  Other investigators observed that elective
            cultures and continuous enrichment failed to biodegrade benzotriazole and indicated that
            the chemical  is expected to resist degradation in the environment (Rollinson and Callely
            1986). In the aquatic environment, the chemical could undergo some photolysis at the
            water's surface (see section II.C.2).
       4.   Biota — The log octanol/water partition coefficient for benzotriazole, 1.34 (CHEMFATE
            1995), suggests that the chemical has a low to moderate potential for partitioning to lipids.
            However, no information was found to indicate whether the chemical will bioaccumulate.

II.  ENVIRONMENTAL FATE

    A.  Environmental Release
        Boric acid is a naturally occurring compound formed from the breaks of other boron compounds.
        It is released into the atmosphere during volcanic eruptions; however, most of this is captured by
        the oceans.  Boric acid also enters the environment as a contaminant from the manufacture and
        industrial and household use of boron-containing compounds; the mining and processing of
        borax; coal, oil and geothermal power generation; and sewage and sludge disposal (U.S. EPA
        1990a). Boric acid is not listed on the EPA's TRI, requiring certain types of U.S. industries to
        report on chemical releases to the environment.

    B.  Transport
        Groundwater movement studies indicate that boron is relatively mobile in sand and gravel
        aquifers, with retardation only occurring as a result of adsorption to clay or organic materials.
        An equilibrium exists between adsorbed and dissolved boron in soils (U.S. EPA  1990a).
                                                                                             DRAFT
                                                C-l 5

-------
APPENDIX C
    C. Transformation/Persistence
       1.   Air — Boron does not appear to persist in the atmosphere as a vapor. As a particulate,
            boron can be removed by either wet or dry deposition (U.S. EPA 1990a).
       2.   Soil — Boric acid is adsorbed onto soil at acidic pH levels, and does not appear to be
            chemically or biologically degraded in soils (U.S. EPA 1990a).
       3.   Water — In natural waters, boron does not appear to be chemically or biologically
            degraded, but exists as undissociated boric acid (U.S. EPA 1990a). Because of its low
            vapor pressure, volatilization is not expected to be a contributing factor for the release of
            boron at the air-water interface (U.S. EPA  1990a).
       4.   Biota — No specific information was found in the secondary sources searched regarding the
            bioaccumulation of boric acid.  However, boron accumulation appears to occur in relation
            to its availability in the surrounding aquatic systems. Tissue concentrations of boron in fish
            from freshwater aquatic systems of varying water quality containing boron or boron
            compounds (not necessarily just boric acid) have been reported to range from 1.8 /^g/g in
            lake charr from a Precambrian shield lake to 20 //g/g in carp from a river system receiving
            agricultural subsurface drainage (U.S. EPA 1990a).

  Analytical properties of commercially produced carbon blacks (all with CAS No. 1333-86-4) are
summarized below. Contaminants, including polynuclear aromatic hydrocarbons (PAHs), adsorb to
carbon-black particles (IARC 1984). These contaminants (some are known carcinogens) are extractable
with organic solvents such as benzene, naphthalene, and toluene (IARC 1984).  The efficiency of the
extraction depends on the solvent, extraction time, type of carbon black, relationship between sample
weight/solvent volume and the amount of extractable material.  The bioavailability of these potential
carcinogens is an important issue in the assessment of the health effects of carbon black (IARC 1984).
Available evidence indicates that when carbon blacks are exposed to biological material, including
human albumin, some release of PAHs occurs, depending on the amount of adsorbed material and the
available adsorptive surface (IARC 1984).

H.  ENVIRONMENTAL FATE

    A. Environmental Release
       Carbon black may be released to the environment from various production facilities and from
       rubber tires in which carbon black is used as a reinforcing agent (U.S. EPA 1981b). The
       objective of the carbon-black industry is to produce large quantities of dense carbon smoke that
       would, under ordinary circumstances, be considered an undesired by-product (U.S. EPA 1981b).
       Consequently, for economic reasons, releases from production facilities are limited by highly
       efficient collection methods.  In the thermal and furnace process plants, systems of electrostatic
       precipitators, cyclones, and bag filters collect over 99% of the black (U.S. EPA 1981b).  In the
       channel production process (no longer used in the U.S.), carbon black was collected by a less
       effective method, impingement on long-channel irons, and larger quantities of carbon black were
       released (U.S. EPA 1981 b).  Releases to the atmosphere may also occur during maintenance
       procedures, from leaks in plant conveying systems, or during loading and unloading operations
       (U.S. EPA 1981b). In 1979, average particulate carbon-black emissions during the manufacture
       of carbon blacks by the oil furnace process ranged from 0.1 kg/thousand kg for fugitive
       emissions to 3.27 kg/thousand kg from uncontrolled main process vents (IARC 1984). More
       recent monitoring data were not found in the secondary sources searched.

       As a result of tire wear, carbon black is deposited in significant quantities along roadways,
       apparently settling out within a few feet of the road (U.S. EPA 1981b).

       In 1978, the U.S. EPA  issued its final regulation on water discharge permits that called for zero
       discharge of carbon black using the best available technology (U.S. EPA 1981b).

    B. Transport
       Carbon black entering the atmosphere or lost from tires ultimately enters the soil or is washed
       into the waterways (U.S. EPA 1981b). No other information was found in the secondary sources
       searched regarding environmental transport of carbon black.

    C. Transformation/Persistence
       No information was found in the secondary sources searched regarding the
       transformation/persistence of carbon black in the atmospheric, aquatic, or terrestrial environment
       or in biota. It is expected to be inert under normal conditions  (U.S. EPA 1981b).

    A.  Environmental Release
        Copper (Cu) commonly exists in three valence states, Cu° (metal), Cu1" (cuprous), and Cu**
        (cupric). It can also be oxidized to a Cu^ state, but there are no important industrial Cu*4*
        chemicals, and Cu+++ ions are rapidly reduced to Cu^ in the environment (ATSDR 1990b).
        Cupric sulfate and cupric chloride are very soluble in water [143 and 706 g/L, respectively (U.S.
        EPA 1987a; ATSDR 1990b)] and, when dissolved, become sources of Cu"' ions; cupro chloride
        is a source of Cu+ ions in solution, but it has comparatively low water solubility [0.062 g/L (U.S.
        EPA 1987a)]. Ethylenediaminetetraacetate (EDTA) has the ability to chelate divalent metal ions
        such as Cu++. The release of Cu^ from the Cu-EDTA complex depends on the concentration of
        other divalent metal ions in solution. Copper occurs naturally in the environment primarily as
        Cu"1"1" salts,  oxides, and complexes; but Cu+ compounds and metallic copper (Cu°) also occur
        naturally (U.S. EPA 1984a). Copper and its compounds are ubiquitous in nature as part of the
        earth's crust and are found in plants and animals (ATSDR 1990b).  The average concentration of
        copper found in the earth's crust is about 50 ppm (ATSDR 1990b).

        Releases to the air from natural sources primarily involve windblown dust; however, volcanoes,
        decaying vegetation, forest fires, and sea water spray also contribute (ATSDR 1990b).
        Anthropogenic sources include releases from copper smelting industries, iron and steel
        industries, coal burning power plants and fabricating operations involving copper (U.S. EPA
        1984a). The mean concentration of airborne copper is 5-200 ng/m3, which is associated with
        particulate matter (ATSDR 1990b). Copper is also released to water from industrial and sewage
        treatment discharges and naturally from soil weathering.  Most of this copper is adsorbed to
        particulate matter. Natural sources of copper account for about 68% of copper released to
        streams and waterways. Domestic wastewater is the largest anthropogenic source of copper
        released to water. Copper can enter the drinking water from the water distribution system and
                                                                                             DRAFT

APPENDIX C
       can exceed 1.3 ppm when the pipes have not been flushed during a period of disuse.  The total
       amount of copper released to water was estimated at 28,848,000,000 tons for 1976; this
       represents about 2.4% of the total amount copper released to the environment.  The majority of
       copper is released to the land primarily from copper mines and mills and is in the form of
       insoluble sulfides or silicates. Other sources include sludge from sewage treatment plants,
       municipal refuse, waste from electroplating, iron and steel producers, and discarded copper-
       containing products (plumbing and wiring) (ATSDR 1990b).

       In 1992, releases of copper to environmental media, as reported to the TRI by certain types of
       U.S. industries, totaled about 55,294,095 pounds of which 41,093,203 pounds were copper
       compounds and 14,200,892 pounds were metallic copper. Of these amounts, 6,329,997 pounds
       of copper compounds and 1,495,369 pounds of metallic copper (14.2%) were released to the
       atmosphere, 72,423 pounds of copper compounds and 41,474 pounds of metallic copper (0.2%)
       were released to surface water, 201,431  pounds of copper compounds and 16,736 pounds of
       metallic copper (0.4%) were released in underground injection sites, and 34,489,362  pounds of
       copper compounds and  12,647,313 pounds of metallic copper (85.2%) were released to land
       (TRI92 1994).

    B. Transport

    C. Transformation/Persistence
       1.   Air — Most of the copper in the air is  in the form of particulate matter (dust) or is adsorbed
            to particulate matter. Larger particles  (>5 um) are removed by gravitational settling,
            smaller particles are removed by other forms of dry  and wet deposition (ATSDR 1990b).
            Atmospheric copper resulting from combustion is associated with sub-micron particles that
            can remain in the troposphere for an estimated 7-30  days and may be carried long distances
            (ATSDR 1990b). In southern Ontario, Canada, the average copper concentration in
            rainwater was 1.57 ppb during 1982, and the average annual wet deposition of copper was
            1.36 mg/m2. The average annual wet deposition for  both central and northern Ontario was
            1.13 mg/m2 (ATSDR 1990b).
       2.   Soil — Most of the copper deposited in the soil is strongly adsorbed primarily to organic
            matter, carbonate minerals, clay minerals, and hydrous iron and manganese oxides.
            Movement through the soil is dependent on the presence of these substances, the pH, and
            other physical and chemical parameters.  The greatest potential for leaching is seen in sandy
            soils with low pH (ATSDR 1990b). Laboratory experiments using controlled models and
            field experiments utilizing core samples have shown that very little copper moves through
            the soil. Core samples showed that some movement occurred as far as the 22.5-25 cm  layer
            of soil, but little, if any, moved below this zone. The evidence indicates that hazardous
            amounts of copper should not leach into groundwater from sludge, even from sandy  soils
            (ATSDR 1990b).
       3.   Water — Copper in solution is present almost  exclusively as the Cu** valence state (U.S.
            EPA 1987a). The Cu* ion is unstable in solution and disproportionates to  Cu** and copper
            metal unless a stabilizing ligand is  present (ATSDR  1990b). In sea water, Cu+ was found  to
            be more stable than in fresh water existing as CuClOH' ions.  A photochemical reduction
            mechanism involving H2O2 is thought to be partly responsible. The presence  of Cu+  is
            highest in the surface layer of seawater and can account for as much as 15% of the copper
            in seawater (ATSDR 1990b). Copper in the Cu^ valence state forms compounds and
            complexes with a variety of organic and inorganic ligands binding to -NH2, -SH, and, to a
            lesser extent, -OH groups (ATSDR 1990b).  The predominant form of copper in aqueous
            solution is dependent on the pH of the solution. Below pH 6, the cupric ion (Cu++)

predominates; copper complexes with carbonate usually predominate above pH 6 (U.S.
EPA 1987a; ATSDR 1990b). The association of copper with organic or inorganic ligands
also depends on the pH and on the CaCO3 alkalinity.  Rivers in the northwestern U.S. with a
relatively high pH (7.0-8.5) and 24-219 ppm CaCO3 were found to contain copper
associated primarily with CO3" and OH" ions. Under these conditions, copper can
precipitate as malachite (Cu2(OH)2CO3). Copper was found to be largely associated with
organic matter in lakes and rivers with a lower pH (4.6-6.3) and CaCO3 concentration (1-30
ppm) such as found in southern Maine (ATSDR 1990b).

Most of the copper entering surface water is in the form of particulate matter, which settles
out, precipitates, or adsorbs to organic matter, hydrous iron and manganese oxides, and
clay; however, the predominating form can change with the amount of rain, pH, content of
runoff, and the availability of ligands (ATSDR 1990b). The processes of complexation,
adsorption and precipitation limit the concentration of copper (Cu**) to very low values in
most natural waters (ATSDR 1990b).  Copper discharged into a river upstream from the
Chesapeake Bay was measured at 53 ppb. Copper associated with particulate material that
were settleable solids accounted for 36 ppb. The copper concentration decreased rapidly
downstream to 7 ppb 2-3 km from the pollution source. The copper concentration in the
settlement, however, was 10 times the concentration in uncontaminated areas (ATSDR
1990b).
Biota — Calculations of the bioconcentration factor in fish for copper have ranged from 10
to 100; however, the majority of copper measurements in fish tissues under environmental
conditions have indicated little, if any, bioconcentration. The copper content of fish muscle
tissue taken from copper-contaminated lakes near Sudbury, Ontario were found to contain
about the same level of copper as fish from uncontaminated areas (ATSDR 1990b). Filter
feeding shellfish, especially oysters, however, were found to significantly concentrate
copper with bioconcentration factors as high as 30,000 (ATSDR 1990b).
                                                                                DRAFT

   This chemical was identified by one or more suppliers as a bath ingredient for the conductive ink
process. This summary is based on information retrieved from a systematic search limited to secondary
sources (see Attachment C-l).  The only exception is summaries of studies from unpublished TSCA

I. CHEMICAL IDENTITY AND PHYSICAL/CHEMICAL PROPERTIES

   The chemical identity and physical/chemical properties of diethylene glycol monoethyl ether acetate
(DGEEA) are summarized below.  In the body, glycol ether esters are apparently saponified (hydrolyzed)
to the parent glycol ether and an organic acid. Systemic effects of the esters are typical of those of the
corresponding parent glycol ethers (HSDB 1996), which for DGEEA, is diethylene glycol monoethyl
ether (DGEE). Therefore, this report will also provide information on DGEE.

H.  ENVIRONMENTAL FATE

    A.  Environmental Release
        No information was found in the secondary sources searched regarding the environmental release
        of DGEEA.  The ester probably enters the environment as does its parent ether, DGEE, i.e., via
        effluents from sites where it is produced or used as a solvent and from other industries (Howard
        1993).  In a national survey of wastewater effluents, DGEE occurred in 5 of 21 industrial
        categories (Howard  1993). Average concentrations of DGEE in wastewater from various
        industries were as follows: 497 mg/L (iron and steel); 52,189 mg/L (printing and publishing);
        175 mg/L (amusement and athletic goods); and 40 mg/L (pulp and paper) (Howard  1993).

                                                                             APPENDIX C
    DGEE has also been found in effluents from publicly-owned treatment works (Howard 1993). A
    drinking-water survey identified DGEE as a contaminant in  11 U.S. cities and 1 county (Howard
    1993).

B.  Transport
    The low vapor pressure of DGEEA (0.05 mm Hg [Gingell et al. 1994]) suggests that
    volatilization from soil or water will not be a significant transport mechanism for the chemical.
    DGEEA is miscible with water and may move through the soil, possibly to groundwater.

    The parent ether, DGEE, is also miscible with water and has an estimated Henry's Law Constant
    of 8.63 x lO'10 atm-m3/mole at 25°C (Howard 1993).  This indicates that volatilization from
    natural bodies of water and moist soils should not be a significant fate process for the ether.  The
    calculated Koc value (20) for DGEE indicates that the chemical will be highly mobile in soil and
    should not partition from the water column to organic matter in sediments and suspended solids
    (Howard 1993).

C.  Transformation/Persistence
    No information was found in the secondary sources searched regarding the
    transformation/persistence of DGEEA in the environment. However, inferences can be drawn
    regarding the fate of DGEEA, based on the following data for its parent ether, DGEE.
    1.   Air — DGEE in ambient air exists mostly in the vapor phase (Howard 1993). The putative
        removal mechanisms for atmospheric DGEE are vapor  phase reactions with
        photochemically produced hydroxyl radicals (Howard 1993).  The estimated rate constant
        of 2.93 x 10'11 cm3/molecule-sec @ 25°C for DGEE corresponds to a half-life of about 13
        hours, assuming the atmospheric concentration of hydroxyl radicals is 5 x 105 per cm3
        (Howard 1993). Wet deposition of DGEE is limited by its short residence time (Howard
        1993).
    2.   Soil — The results of aqueous screening tests indicate that biodegradation is the most
        significant mechanism for the removal of DGEE from aerobic soil (see the results of
        screening tests in section II.C.3) (Howard 1993). Hydrolysis and direct photolysis are not
        important mechanisms for the removal of DGEE from soil (Howard 1993).
    3.   Water — The results of aqueous screening tests indicate that biodegradation  is the primary
        mechanism for the removal of DGEE from water (Howard 1993).  After 16 days of
        acclimation, losses of 39.8% and 34.3% were recorded  using an  8-hour Warburg test and a
        5-day BOD (biochemical oxygen demand) test, respectively (Howard 1993). In two assays
        conducted without acclimation, the BOOT values after  20-day incubation periods were 48
        and 87% (Howard 1993).  Using the Zahn-Wellens screening method, a >90% loss of the
        original concentration of DGEE (400 ppm) occurred in  28 days (Howard 1993).  DGEE
        should not undergo hydrolysis or direct photolysis in the aquatic environment (Howard
        1993).
    4.   Biota — The calculated log BCF (bioconcentration factor) of-0.34 for DGEE and its
        miscibility with water indicate that the chemical will not bioconcentrate in aquatic
        organisms (Howard 1993).
                                                                                  DRAFT

C.  Transformation/Persistence

        an atmospheric half-life of about 16 hours (HSDB 1995).
    2.   Soil — In general, biodegradation and leaching would be the most important removal
        processes for glycoi ethers in soils (U.S. EPA 1984b).
    3.   Water — DOME was degraded by 0, 21, and 66% after 5, 10, and 20 days respectively
        when settled waste water or sewage sludge was used as inoculum (HSDB 1995).
    4.   Biota — Based on the high water solubility and low estimated bioconcentration factor of

II. ENVIRONMENTAL FATE

    A.  Environmental Release
        In 1993 as reported to the TRI by certain types of U.S. industries, environmental releases of all
        glycol ethers totaled 45.9 million pounds; diethylene glycol n-butyl ether is not reported
        separately (TRI93  1995). The chemical has been detected in the waste water effluents from
        industries at average concentrations ranging from 7 to 244 mg/L (HSDB 1995).

    B.  Transport
        Because of its miscibility with water, diethylene glycol n-butyl ether will partition to the
        water column and be highly mobile in soils. In the atmosphere, the chemical may be
        removed  by precipitation and dissolution in clouds (HSDB 1995).

 C. Transformation/Persistence
    1.   Air — In the atmosphere, diethylene glycol n-butyl ether should exist almost entirely in the
         vapor phase. The estimated half-life for reaction with hydroxyl radical is 11 hours (HSDB
         1995).
    2.   Soil — Diethylene glycol n-butyl ether should partition to the water column of moist soils
         and volatilization will not be significant (HSDB 1995).
    3.   Water — Diethylene glycol n-butyl ether is not expected to undergo hydrolysis and the
         Henry's Law Constant indicates that volatilization would be slow. However, aerobic
         biodegradation may be an important removal mechanism from aquatic systems (HSDB
         1995). No other information was found.

H. ENVIRONMENTAL FATE
    A. Environmental Release
        /y.W-Dimethylformamide is a widely used solvent for organic compounds where a low rate of
        evaporation is required. The chemical may be emitted to the environment by effluents from a
        variety of petrochemical industries (Howard 1993).

        N.Af-Dimethylformamide has been identified in the air over a hazardous waste site in Lowell,
        MA and a neighboring industry at concentrations of 2.18 and >50 ppb, respectively; in 1 of 63
        industrial wastewater effluents (<10 jWg/L); and in waste effluent of a plastics manufacturer
        (28,378 ng/juL extract). The chemical was listed as a contaminant found in drinking water

    samples in several U.S. cities, and in 1 of 204 samples in a national survey of surface waters
    (Howard 1993).

 B. Transport
    Volatilization of JV.A'-dimethylformamide from land or water is not expected to be significant
    (Howard 1993). The complete water solubility suggests that the chemical can be removed from
    the atmosphere by rainfall. ^A^-dimethyl-formamide is  expected to be highly mobile in soils
    and will probably leach into groundwater (U.S. EPA  1986).

 C. Transformation/Persistence
    1.   Air — Based upon the vapor pressure (3.87 mm Hg @ 25 °C), A^TV-dimethyl-formamide is
         expected to exist almost entirely in the gaseous phase in the atmosphere. The vapor phase
         reaction of A^A^-dimethylformamide with photochemically produced hydroxyl radicals is
         likely to be an important fate process.  The rate constant for the vapor phase reaction with
         photochemically produced hydroxyl radicals is estimated to be 2.24 x 10"10 cm3/molecule-
         sec at 25 °C,  which corresponds to an atmospheric half-life of about 2 hours (Howard 1993).
         In smog chamber studies, 7V,./V-dimethylformamide  was relatively nonreactive with regard to
         photochemical oxidant formation (U.S. EPA 1986).
    2.   Soil — The calculated Koc of 7 indicates that JV;JV-dimethylformamide will be highly
         mobile in soils and the Henry's Law Constant (7.39 x 10E'8 atm-mVmole) suggests that
         volatilization from soils will not be important (Howard 1993). Aqueous screening and a
         river die-away test suggests that biodegradation of A^A'-dimethylformamide in soil will be
         rapid (HSDB 1996). When wastewater containing 250 mg/L A^A^dimethylformamide was
         aerobically treated with activated sludge, 95% of the chemical was degraded  in  18 hours
         (U.S. EPA 1986).
    3.   Water — The estimated Koc (ranging in the high mobility class for soil) indicates that N,N-
         dimethylformamide will not partition from the water column to organic matter contained in
         the sediments and suspended solids. The Henry's Law Constant suggests that volatilization
         from environmental waters will not be important (Howard 1993). A^Af-Dimethylformamide
         hydrolyzes slowly in neutral pH water, but hydrolysis is accelerated by acids  and bases
         (U.S. EPA 1986).  Af./V-Dimethylformamide can be biodegraded by activated sludge,
         although an acclimation period is usually required.  River die-away data suggest that the
         biodegradation of the chemical should be rapid (Howard 1993).
    4.   Biota — The bioconcentration factor of -1.01 (log) indicates that N, JV-dimethyl-formamide
         will not bioconcentrate in aquatic organisms (Howard 1993).
                                                                                    DRAFT

H.  ENVIRONMENTAL FATE

    A.  Environmental Release
        Ethanolamine is a colorless viscous liquid with an unpleasant, fishy, ammoniacal odor (Budavari
        et al.  1989; Grant 1986). It is released to the environment primarily from emissions and
        effluents from sites of industrial production or use, from disposal of consumer products
        containing ethanolamine such as cleaning products, and use of agricultural products in which it is
        used as a dispersing agent.  Ethanolamine can also be released to the environment in urine.
        Ethanolamine was one of the primary amines identified in aerosol samples collected over the
        North Atlantic Ocean. Highest concentrations were found in samples taken near North America,

    Bermuda, the Azores, and in the Arctic Circle, and low concentrations in the Gulf stream and in
    the equatorial North Atlantic (Gorzelska and Galloway 1990, as reported in TOXLINE).

B.  Transport
    Ethanolamine is completely soluble in water (Benya and Harbison 1994), and if released to the
    soil, would not be expected to adsorb appreciably to organic material [calculated Koc = 5 (HSDB
    1995)]. Ethanolamine has the potential to leach into groundwater. The volatilization of
    ethanolamine from water is believed to be negligible [Henry's Law constant = 4E-8 atm-mVmole
    @ 25°C (CHEMFATE 1995)].

C.  Transformation/Persistence
    1 •   Air — The dominant removal mechanism is expected to be reaction with photochemically
        generated hydroxyl radicals.  The calculated half-life for ethanolamine vapor reacting with
        hydroxyl radicals is 11 hours. The complete water solubility of ethanolamine suggests that
        this compound may also be removed from the atmosphere in precipitation (HSDB 1995).
        Soil — If released to soil, ethanolamine is expected to biodegrade fairly rapidly following
        acclimation and to leach in soil. The half-life is on the order of days to weeks.
        Volatilization from soil surfaces is not expected to be an important removal process (HSDB
        1995).
        Water — If released to water, ethanolamine is expected to undergo biodegradation. The
        half-life of this compound  may range from a few days to a few weeks depending, in large
        part, on the degree of acclimation of the system. Bioconcentration in aquatic organisms,
        adsorption to suspended solids and sediments, and volatilization are not important removal
        processes (HSDB 1995). Tests utilizing settled sewage seed showed that 0%, 58.4%, or
        75% of added compound was biodegraded after 5, 10, or 50 days, respectively.  In a closed
        activated sludge system, 93.6% of the  added chemical was biodegraded (CHEMFATE
        1995).
        Biota — The bioconcentration factor of <1 (based on a log KQW of-1.31) and the complete
        water solubility of ethanolamine suggest that the compound does not bioconcentrate in
        aquatic organisms (HSDB  1995).

    A.  Environmental Release
        In 1992 as reported to the TRI by certain types of U.S. industries, a total of 17.2 million pounds
        of ethylene glycol was released to the environment. The total consisted of 10.25 million pounds
        released to the atmosphere, 6.25 million pounds to ground and surface waters, and 0.7 million
        pounds to land (TRI92 1994). The major source of ethylene glycol in the environment is the
        disposal of used antifreeze.  The chemical was found in concentrations of O.05-0.33 mg/m3 as
        aerosol and O.05-10.4 mg/m3 as vapor in ambient air samples collected above bridges following
        spray application of a deicing fluid containing 50% ethylene glycol (ATSDR 1993a).

    B.  Transport
        The low Henry's Law Constant and high water solubility indicate that ethylene glycol will not
        volatilize from surface waters.  Based on the calculated Koc the chemical is expected to be

    highly mobile in soils and can leach into ground waters; however, ethylene glycol is readily
    biodegraded (ATSDR 1993a; U.S. Air Force 1989a). Removal from the atmosphere in rainfall is
    possible (ATSDR 1993a).

 C. Transformation/Persistence
    1.   Air — The half-life for reaction of ethylene glycol with hydroxy radicals in the atmosphere
         is 2.1 days (CHEMFATE 1995).  Estimated half-lives for photochemical oxidation range
         from 24 to 50 hours (ATSDR 1993a).
    2.   Soil — Several genera of soil microbes have been shown to completely degrade
         concentrations of 1-3% ethylene glycol within 3 days (ATSDR 1993a).  Clostridium
         glycolicum, isolated from mud, degraded the chemical under anaerobic conditions
         (concentration and time not given) (CHEMFATE 1995).
    3.   Water — Biodegradation of ethylene glycol has been demonstrated by acclimated and
         unacclimated microorganisms from a variety of aqueous media (ATSDR 1993; U.S. Air
         Force 1989a). Complete degradation occurred with activated sewage sludge in
         approximately 80 hours (CHEMFATE 1995). Several Mycobacterium sp. and Alcaligenes
         sp. are capable of utilizing ethylene glycol as a sole carbon source (CHEMFATE 1995). In
         contrast, the half-life for reaction with hydroxy radicals in aqueous solution has been
         calculated as 2.84 years (CHEMFATE 1995).
    4.   Biota — The high water solubility, rapid microbial degradation, and low to moderate
         bioconcentration factor indicate that ethylene glycol would not be expected to
         bioaccumulate in aquatic organisms.
                                                                                   DRAFT

H.  ENVIRONMENTAL FATE

    A. Environmental Release
       EDTA does not occur naturally in the environment (HSDB 1995). The main sources of EDTA
       released to the environment are probably domestic sewage and industrial effluents, resulting
       from the chelating applications of the chemical (HSDB 1995). Other sources of release of the
       chemical include the use of herbicides and the land disposal of products that contain EDTA
       (HSDB 1995).

       In 1974 in England, concentrations of EDTA ranging from 0 to 1120 ppb were detected in the
       Lea River and concentrations ranging from 200 to 1200 ppb were detected in the effluent from
       the Rye Meads sewage treatment plant (HSDB 1995). In other studies, EDTA concentrations of
       100 to 550 ppb were detected in sewage effluents (no other details were available) (Verschueren
       1983). Other monitoring data were not found in the secondary sources searched.

B.  Transport
    Under environmental conditions (pH 5-10), EDTA completely dissociates, as is indicated by
    pKa, = 0.26, PKa2 = 0.96, PKa3 = 2.60 and PKa4 = 2.76 (HSDB  1995). This suggests that
    volatilization from water or soil would not be significant for EDTA. A study of EDTA
    degradation in soils detected no volatilization (HSDB 1995).
    EDTA and complexes of EDTA with  alkaline earth metals and trace metals demonstrate
    negligible adsorption to silica, humic  acid, kaolin, kaolinite (EDTA only), river sediments, and
    humus solids (HSDB 1995). According to at least one report, EDTA leaches readily in soil
    (HSDB 1995).

C.  Transformation/Persistence
    1.   Air — EDTA released to the atmosphere may undergo direct photolysis or may react with
        photochemically-generated hydroxyl radicals (HSDB 1995). The estimated half-life for the
        reaction of EDTA vapor with photochemically generated hydroxyl radicals in the
        atmosphere is 3.01 days (HSDB  1995).
    2.   Soil — EDTA released to the soil is expected to complex with trace metals and alkaline
        earth metals that occur in the soil, increasing their total solubility (HSDB 1995).
        Eventually, EDTA may exist predominantly as the Fe(III)  chelate in acidic soils and as the
        Ca chelate in alkaline soils (HSDB 1995).
        Biodegradation is the predominant removal mechanism  for EDTA in aerobic soils, whereas
        biodegradation of the chemical is negligible in anaerobic soils (HSDB 1995).
        Mineralization values for 2-4 pprn EDTA in various soils range from 13 to 45% after 15
        weeks and from 65 to 70% after  45 weeks (HSDB 1995).
    3.   Water — EDTA released to water is expected to complex with trace metals and alkaline
        earth metals (HSDB 1995).  In water under aerobic conditions, EDTA undergoes
        biodegradation relatively slowly. As in soil, the anaerobic biodegration of EDTA in water
        is negligible (HSDB 1995).  Possible biodegradation products of the ammonium ferric
        chelate of EDTA include the following: ethylenediamine triacetic acid (EDS A),
        iminodiacetic acid (IDA), N,N-ethylenediamine diacetic acid (N,N-EDDA), N,N'-EDDA,
        ethylenediamine monoacetic acid (EDMA), nitrilotriacetic acid (NTA) and glycine (HSDB
        1995).
        In water, EDTA may react with photochemically-generated hydroxyl radicals (half-life, 229
        days) or undergo photodegradation. In an aqueous solution, the Fe(III) complex of EDTA
        degraded with a half-life of  11.3  minutes when exposed to artificial sunlight (HSDB 1995).
        The following were photodegradation products of Fe(III)-EDTA: carbon monoxide,
        formaldehyde, ED3A, N,N-EDDA, N,N'-EDDA, IDA, EDMA and glycine (HSDB 1995).
    4.   Biota — The fish bioconcentration factors for EDTA (<2 and 19) suggest that the chemical
        will not bioaccumulate in aquatic organisms (HSDB 1995). It is not expected to adsorb to
        suspended solids or sediments (HSDB 1995).
                                                                                 DRAFT

  .  ENVIRONMENTAL FATE

    A. Environmental Release
       Fluoroboric acid may be released into the environment in emissions and effluents from facilities
       involved in its manufacture or use. It is used primarily in industrial metal plating solutions
       (60%), in the synthesis of diazo salts (20%), and in metal finishing (20%) (HSDB 1995).  It is
       used in bright dipping solutions for Sn-Pb alloys in printed circuits and other electrical
       components (HSDB 1995).

    B. Transport
       No information was found in the available secondary sources on the environmental transport of
       fluoroboric acid. Its miscibility with water indicates that transport in aqueous systems is very
       likely.

    C. Transformation/Persistence
       FLUOROBORIC ACID:
       1.   Air—No information was found in the available secondary sources on the transformation
            and persistence of fluoroboric acid or fluoroborates in the atmosphere.
       2.   Soil — No information was found in the available secondary sources on the transformation
            and persistence of fluoroboric acid or fluoroborates in soil. Fluoroboric acid may undergo
            limited hydrolysis in moist soils (Budavari et al. 1989).
       3.   Water— Fluoroboric acid undergoes limited hydrolysis in water to form
            hydroxyfluoroborate ions, the major product is BF3OH' (Budavari et al. 1989).
       4.   Biota — No information was found in the available secondary sources on the
            biotransformation or bioconcentration of fluoroboric acid or fluoroborates.  Rapid urinary
            excretion of tetrafluoroborates suggests that these salts would not bioaccumulate.

 FLUORIDES:
 1 •   Air — Gaseous inorganic fluorides undergo hydrolysis in the atmosphere; however,
     particulate forms are relatively stable and do not hydrolyze readily (ATSDR 1993b).
 2.   Soil — Fluorides tend to persist in soils as fluorosilicate complexes under acidic conditions
     and as calcium fluoride under alkaline conditions.  Sandy acidic soils favor the formation of
     soluble forms (ATSDR 1993b).
 3.   Water — In dilute solutions and at neutral pH, fluoride is generally present as dissolved
     fluoride ion. High calcium carbonate levels may lead to precipitation as calcium fluoride
     (ATSDR 1993b).
 4.   Biota — Fluorides have been shown to accumulate in some aquatic organisms (ATSDR
     1993b). Soluble forms of fluoride are taken up by terrestrial plants and converted into
     fluoro-organic compounds (ATSDR 1993b).

H. ENVIRONMENTAL FATE

    A.  Environmental Release
        Formaldehyde is a colorless gas at room temperature with a characteristic pungent, straw-like
        odor that becomes suffocating and intolerable at increasing concentrations (U.S. EPA 1985b;
        Budavari et al. 1989; Verschueren 1983). It is released into the environment from natural and
        man-made sources.  It is a product of combustion and is found in smoke from wood, wood
        products, and tobacco; gasoline and diesel engine exhaust; and in the effluent from power plants,
        incinerators, and refineries (Howard 1989). It can also be made indirectly in the atmosphere by
        the photochemical oxidation of other organic molecules, many of which are also products of
        combustion (U.S. EPA 1985b; Howard 1989). The contribution of formaldehyde to the

   atmosphere from this indirect source has been estimated to be twice that from automobiles (U.S.
   EPA 1985b). Formaldehyde is found in some fruits and vegetables including apples (17.3-22.3
   Hg/g), green onions (13.3-26.3 u.g/g), carrots (6.7-10.0 |ig/g), and tomatoes (5.7-7.3 ug/g). It has
   also been measured in commercial shrimp at 0.39-2.15 mg/kg (U.S. EPA 1985b). Solutions of
   the gas in water (typically, 37% formaldehyde) are known as formalin and are commonly used as
   biological preserving agents (U.S. EPA 1985b). Atmospheric levels of formaldehyde have been
   extensively monitored around the world. Air concentrations range from 0-1 parts-per-billion
   (ppb) measured off the West coast of Ireland to 24-59 ppb in Los Angeles during a
   photochemical smog episode (U.S. EPA 1985b).  Only 25%  of 749 air samples taken from
   suburban/urban sites across the U.S. were found to contain over 2.7 ppb formaldehyde (U.S.
   EPA 1985b). Concentrations increase with automobile traffic and during photochemical smog
   episodes (Howard 1989; U.S. EPA 1985b), and decrease markedly with altitude (U.S. EPA
   1985b). Formaldehyde concentrations in indoor air vary with activities involving combustion
   and materials used in construction.  Levels of 33-380 ppb were measured in a test kitchen with a
   gas stove, concentrations of 0.06-1.83 ppb were measured in homes using urea-formaldehyde
   particle board,  and levels of <0.41-8.2 parts-per-million (ppm) were measured in homes with
   urea-formaldehyde foam insulation (U.S. EPA 1985b). Higher levels are also measured in areas
   where formaldehyde solutions (formalin) are used, such as funeral homes  (0.35-1.39 ppm),
   anatomy laboratories (1  ppm, mean),  and academic laboratories (1.33-2.48 ppm) (U.S. EPA
   1985b). Drinking water supplies were found to be free from formaldehyde contamination in a
   national survey of suspected carcinogens in drinking water.  Formaldehyde was also not found in
   seawater, and was found in only 1/204 samples at 12 ppb from heavily industrialized river basins
   in the U.S.  It was found in the effluent streams from two chemical plants  and one sewage
   treatment plant (Howard 1989).

   In 1992, releases of formaldehyde to environmental media, as reported to the TRI by certain
   types of U.S. industries, totaled about 16,435,148 pounds. Of this amount, 10,903,227 pounds
   (66.34%) were released to the atmosphere, 4,916,248 pounds (29.91%) were released in
   underground injection sites, 441,244 pounds (2.68%) were released to surface water, and
   174,429 pounds (1.06%) were released to land (TRI92 1994).

B. Transport
   Formaldehyde in solution reacts with water to become hydrated. In this form, it becomes less
   volatile than water; thus, volatilization from the aquatic environment is not expected to be
   significant (U.S. EPA 1985b). Formaldehyde is known to leach into the soil, and its high water
   solubility and calculated soil sorption coefficient (Koc =5) indicate relatively high mobility, but
   the actual fate of formaldehyde in the soil is largely unknown (Howard  1989; U.S. EPA 1985b).
   In the atmosphere, formaldehyde will transfer into rainwater and also adsorb to aerosol
   particulates (U.S. EPA 1985b).  Half-lives of 50 and 19 hours were predicted from a model
   system for wet and dry deposition, respectively (Howard 1989).

C. Transformation/Persistence
   1.   Air — Formaldehyde rapidly reacts with free radicals produced by sunlight in the
        atmosphere. These include primarily hydroxyl radicals and, to a lesser extent, other
        radicals, especially chlorine and nitrate.  A half-life for formaldehyde of about 0.8 days was
        calculated for the reaction with hydroxyl radicals (U.S. EPA 1985)b.  Formaldehyde also
        undergoes direct photolysis (significant absorption of wavelengths between 290 and 370
        nm.). The atmospheric half-life of formaldehyde was calculated to be 0.17 days at sea level
        with the sun at 30° zenith angle. Calculated for the same conditions, but at an altitude of 10
        km, the half-life was reduced to 0.08 days (U.S. EPA 1985b).
                                                                                   DRAFT
                                         C-43

-------
 APPENDIX C
        2.   Soil—No information is available on the fate of formaldehyde in the natural soil
            environment. However, a number of bacteria and yeasts isolated from soil were able to
            degrade formaldehyde, suggesting that formaldehyde released to the soil is susceptible to
            microbial degradation (U.S. EPA 1985b; Howard 1989).
        3.   Water — Formaldehyde in water is subject to biodegradation. Under aerobic conditions
            complete degradation was observed in about 30 hours at 20°C utilizing natural water from a
            lake in Japan and a known amount of formaldehyde. Degradation occurred in about 48
            hours under anaerobic conditions. No degradation was seen with sterilized lake water (U.S.
            EPA 1985b). Activated sludges were shown to be efficient in decomposing formaldehyde

II.  ENVIRONMENTAL FATE

    A.  Environmental Release
        Formic acid is a colorless, highly caustic liquid with a pungent odor (Budavari et al. 1989; NTP
        1992). It is produced in large quantities (48 million pounds in 1984) and is released to the
        environment primarily from industrial sources during its production and uses including textile
        dying and finishing (21% of production); pharmaceuticals (20%); rubber intermediate (16%);
        leather and tanning treatment (15%); and catalysts (12%). Formic acid is also a component of
        certain paint strippers and is released in photoprocessing effluents (HSDB 1995). Other sources
        of formic acid include releases from forest fires, lacquer manufacturing, trash and plastic
        burning, thermal degradation of polyethylene, and tobacco smoke (NTP 1992).  Formic acid also
        occurs naturally in plants and insects, as a product of microbial degradation of organic matter,
        and as a product of photooxidation of biogenic and anthropogenic compounds (HSDB 1995). A
        constituent of ant, wasp, and bee venom, formic acid occurs in mammalian muscle tissue, sweat,
                                                C-45
                                                                                             DRAFT

APPENDIX C
       and urine (NTP 1992).  Formic acid has been measured at concentrations ranging from 4 to 72
       ppm in the atmosphere. It has been detected in river and surface water, in unfinished industrial
       waste water, and in municipal sewage and discharge water at concentrations ranging from 10 to
       80,000 ^g/L (SRI 1981, as reported in NTP 1992).

    B. Transport
       Formic acid is soluble in water and would not be expected to adsorb significantly to soil or
       sediments. Formic acid should leach from some soils into groundwater where it probably would
       biodegrade. The Henry's Law Constant for formic acid (1.67 x 10'7 atm-m3/mole) indicates that
       volatilization from water would not be significant. The potential for bioconcentration is low
       (HSDB 1995).

    C. Transformation/Persistence
       1.   Air— In the atmosphere, formic acid is rapidly scavenged by rain and dissolved in cloud
            water and aerosols, reacting with dissolved hydroxyl radicals. In the vapor phase, the acid
            also reacts with photochemically produced hydroxyl radicals (half-life 34 days) and
            possibly with alkenes that may be present in urban air (HSDB 1995).
       2.   Soil — If released on land, formic acid is expected to  leach from soils where it would
            probably biodegrade based on the results of screening studies (HSDB 1995). A field study
            followed an industrial waste containing 11.4% formic acid that was disposed of by deep
            well injection as it traveled a distance of 427-823 meters over a 2 to 4-year period.  Formic
            acid was not detected in two observation wells, while  a third well contained 0.4%. The
            disappearance of the acid was attributed to anaerobic degradation or to reaction with
            mineral material in ground water (HSDB 1995).
       3.   Water — If released to water, formic acid should biodegrade and not adsorb significantly to
            sediment (HSDB 1995).
       4.   Biota — The estimated bioconcentration factor of 0.22 (based on a log/water partition
            coefficient of-0.54) suggests that formic acid would not bioaccumulate in aquatic
            organisms (HSDB 1995).

II.  ENVIRONMENTAL FATE

    A.  Environmental Release
        Graphite exists as a black or gray crystalline mass and occurs naturally in lump, amorphous, and
        flake forms (Pendergrass 1983). It is found in most parts of the world (Pendergrass 1983) and is
        usually found with impurities such as quartz, mica, iron oxide, and granite. The crystalline silica
        content can range from 2% to 25% (ACGIH 1991).  Synthetic graphite is produced by heating a
        mixture of coal or petroleum coke, a binder, and a petroleum-based oil to facilitate extrusion
        (ACGIH 1991). Although graphite occurs naturally, exposure to graphite is expected to be
        primarily occupational.  No information on the environmental release of graphite was found in
        the secondary sources searched.
                                                                                            DRAFT

-------
APPENDIX C
    B. Transport
       Graphite is insoluble in water (NIOSH 1994) and, therefore, would not be expected to be
       transported in surface of ground water. No volatilization is expected to occur under natural
       conditions.

    C. Transformation/Persistence
       1.   Air — Graphite could be present in air as particulate matter which has a settling time of
            days.
       2.   Soil—No information on the transformation/persistence of graphite in soil was found in
            the secondary sources searched.
       3.   Water — No information on the transformation/persistence of graphite in water was found
            in the secondary sources searched.
       4.   Biota — Graphite does not dissociate in water. Although it may be ingested by bottom
            feeders, it is not expected to accumulate in aquatic organisms..

                      CHEMICAL SUMMARY FOR HYDROCHLORIC ACID

    This chemical was identified by one or more suppliers as a bath ingredient for the electroless copper,

    A.  Environmental Release
        HCI occurs naturally in gases evolved from many volcanoes.  There are apparently no other
        natural sources of the chemical, but chlorides are present in the minerals halite, sylvite, and
        carnal lite, and in seawater (HSDB 1995).

-------
APPENDIX C
       HC1 is released to the environment from its production and various other industrial processes
       (WHO 1982). Sources of its release include refuse incineration and the secondary metals
       industry (such as the smelting of scrap, rather than ore) (HSDB 1995). It is also released from
       the thermodecomposition of gases, as a by-product in the numerous dehydrohalogenation
       processes in the production of unsaturated compounds from the parent chlorinated hydrocarbon,
       and from coal-fired power plants (HSDB 1995).

       In 1992, environmental releases of hydrochloric acid, as reported to the TRI by certain types of
       U.S. industries, totaled about 287.3  million pounds, including 207.8 million pounds to
       underground injection sites, 77.1 million pounds to the atmosphere, 1.9 million pounds to surface
       water, and 432,770 pounds to  land (TRI92 1994).  Hydrochloric acid ranks second highest in the
       TRI for total releases and transfers.

    B. Transport
       HC1, highly soluble in water, may be removed from the atmospheric environment by wet
       deposition.  This was illustrated by  a study in the Netherlands in which the chemical was washed
       out from the plume of a coal fired power plant (HSDB  1995).

       Anhydrous HC1 spilled onto the soil undergoes rapid evaporation and is not expected to infiltrate
       the soil (HSDB 1995). In contrast,  hydrochloric acid spilled onto soil will infiltrate and will
       dissolve some soil materials, particularly those of a carbonate base. A portion of the acid will be
       neutralized, but significant amounts will remain, available for transport to the ground water
       table. The presence of water in the  soil  influences the rate of movement of the chemical (HSDB
       1995).

    C. Transformation/Persistence
       I.   Air — No information was found in the secondary sources searched regarding the
            transformation/persistence of HCl/hydrochloric acid in the atmosphere.
       2.   Soil — Hydrochloric acid spilled onto soil will infiltrate and will dissolve some soil
            materials, particularly those of a carbonate base, which will neutralize a portion of the acid
            (HSDB 1995). Information regarding other potential reactions of hydrochloric acid in the
            soil was not available in  the secondary sources searched.
       3.   Water — HC1 in water dissociates  almost completely; the hydrogen ion is captured by the
            water molecules to form the hydronium ion (HSDB 1995).
       4.   Biota — No information was found in the secondary sources searched regarding the
            transformation/persistence of HCl/hydrochloric acid in biota.

        No information was found in the secondary sources searched regarding the environmental release
        of hydrogen peroxide.  Solutions of hydrogen peroxide gradually deteriorate (Budavari et al.

        recognized to be a key component and product of the earth's lower atmospheric photochemical
        reactions, in both clean and polluted atmospheres. Atmospheric hydrogen peroxide is also
        believed to be generated by gas-phase photochemical reactions in the remote troposphere (IARC

       3.   Water — Hydrogen peroxide is a naturally occurring substance. Surface water
            concentrations of hydrogen peroxide have been found to vary between 51-231 mg/L,
            increasing both with exposure to sunlight and the presence of dissolved organic matter
            (IARC 1985).
       4.   Biota — Hydrogen peroxide is a naturally occurring substance. Endogenous hydrogen

II.  ENVIRONMENTAL FATE
    A.  Environmental Release
        Hydroxyacetic acid is a water soluble solid used in the processing of textiles, leather, and metals,
        in pH control, and wherever an inexpensive organic acid is needed (Budavari et al. 1989).  The
        chemical can be found in spent sulfite liquor from pulp processing and occurs naturally in sugar
        cane syrup (HSDB 1995).  Hydroxyacetic acid has been detected in the Gulf of Main at
        concentrations of 0-78 yUg/L; in water samples collected at a 3 meter depth in the Belgian zone of
        the North Sea; in the eastern parts of the English Channel at concentrations ranging from 0.9 to
        3.1 //mol/L; and in five Madison, Wisconsin, Lakes and in Falkland Islands waters as a product
        of algal photosynthesis (CHEMFATE 1995).

-------
APPENDIX C
    B. Transport
       No information on the transport of hydroxyacetic acid was found in the secondary sources
       searched. Hydroxyacetic acid is soluble in water and would be expected to leach through soil.
       The vapor pressure of 8.1 mm Hg @ 80°C indicates that the chemical is moderately volatile and,
       therefore, may volatilize to some extent from soils and water.  However, a Henry's Law Constant
       is not available and it is stated that the chemical is water soluble. Hence, even though the vapor
       pressure is relatively high, volatilization from water may be negligible due to its high water
       solubility.

    C. Transformation/Persistence
       1.   Air — No information on the transformation/persistence of hydroxyacetic acid in air was
            found in the secondary sources searched.
       2.   Soil — The chemical was not biodegraded by 10 strains of Arthobacter globiformis and
            slowly degraded byAlcalignes sp. (CHEMFATE 1995).
       3.   Water — Stream and groundwater bacteria degraded the chemical with half-lives of 73 days
            and 4.5 days, respectively (CHEMFATE 1995).
       4.   Biota — The low log octanol-water coefficient (-1.11) suggests that hydroxyacetic acid
            would not bioaccumulate.

H.  ENVIRONMENTAL FATE

    A. Environmental Release
       Isophorone is not listed on the TRI (TRI93 1995). Information on the amounts released into
       various environmental media was not found in the available secondary sources.

    B. Transport
       If released to soil or water, isophorone may be transported to air by volatilization (Howard
       1990). Based on a Henrys Law Constant of 5.8 x 10'6 atm-mVmol, the half-life from a model
       river 1 m deep and flowing 1 m/sec was estimated to be about 7.5 days (Howard 1990).
       Isophorone is not expected to be adsorbed to suspended solids or sediments. Koc values of 25
                                                                                    DRAFT

 APPENDIX C
        and 384 have been estimated for isophorone from data on water solubility (12 g/L at 20°C) and
        Kow (log Kow = 1.67 at 20°C), indicating that leaching through soils to ground water is possible
        (Howard 1990). Based on its vapor pressure of 0.3 mm Hg, isophorone is expected to exist in
        the air primarily in the vapor phase (Howard 1990).  Isophorone emitted to the atmosphere in
        particulate form may be removed by wet or dry deposition (Howard 1990).

    C.  Transformation/Persistence
        1.   Air — The major degradation pathway for isophorone in air is expected to be by reaction
            with ozone, with a estimated half-life of 39 min (Howard 1990). Reaction with
            photochemically generated hydroxyl radicals is not expected to be as significant (half-life 3
            hr) (Howard 1990). Overall half-life in air has been estimated to be 32  min (Howard 1990).
        2.   Soil — The potential exists for transport of isophorone to ground water by leaching through
            soil (Howard 1990). Biodegradation is a likely degradation pathway in soils.
        3.   Water — Isophorone is not expected to be adsorbed to suspended solids or sediments, or to
            be photolyzed, oxidized by reaction with singlet oxygen, oxidized by alkylperoxy radicals
            or undergo chemical hydrolysis (Howard 1990). Isophorone may undergo biodegradation
            in water (Howard 1990).
        4.   Biota— Isophorone is not expected to bioaccumulate (Howard 1990).  A bioconcentration
            factor of 7 was reported for bluegill sunfish (Howard 1990). The half-life of isophorone in
            fish tissue was estimated to be 1 day, indicating a low potential for bioaccumulation
            (Howard 1990)

II. ENVIRONMENTAL FATE

   A.  Environmental Release
       Isopropanol is released into the environment in emissions from chemical manufacturing plants
       and as a result of its use in consumer products such as a rubbing alcohol, cosmetics, and
       antifreezes (HSDB 1995). The chemical is also released as a natural volatile from vegetation,
       nuts, and milk products, and as a result of micrpbial degradation of animal wastes (HSDB 1995).
                                                                                    DRAFT
                                           C-57

-------
APPENDIX C
       Of the total 1,357,992 pounds of isopropanol released to the environment in 1993, as reported to
       the TRI by certain types of U.S. industries, 1,357,242 pounds were released to the atmosphere
       and 750 pounds were released onto land; no releases were reported for surface waters or
       underground injection sites (TRI93 1995).

    B. Transport
       Following releases onto land, isopropanol is likely to volatilize into the atmosphere due to its
       high vapor pressure (32.4 mm Hg at 20°C). Transport through soil to groundwater is also
       possible considering the chemical's water solubility (>10%) and low Koc value (25).  When
       released into water, isopropanol will slowly volatilize into the atmosphere (Henry's law constant
       7.89 * 10"6 atm mVmole); the estimated half-life for volatilization from water 1 m deep with a 1
       m/sec current and a 3 m/sec wind  speed is 3.6 days (Mackay et al. 1992). Because of its
       miscibility with water and its low potential for adsorption to sediments, downstream transport is
       also possible (HSDB 1995). Transport through the atmosphere may be limited by
       photodegradation and removal in precipitation (HSDB 1995).

    C. Transformation/Persistence
       1.   Air —  Isopropanol exhibited a low level of reactivity when tested in a smog chamber; a
            20% decrease in concentration occurred in 5 hr and 250-255 min was  required for
            maximum NOX production (CHEMFATE 1995).  The rate constant for its reaction with OH
            radicals is 0.547E-11, and that for reaction with O(3P) radicals is 0.22E-12 (CHEMFATE
            1995). Photo-oxidation half-lives of 6.2-72 hr (based on rate of disappearance of the
            hydrocarbon) and 6.2-72 hr (based on the OH reaction rate constant) have been reported
            (Mackay et al. 1992).
       2.   Soil — A half-1 ife of 24-168 hr was calculated from an estimate of the biodegradation half-
            life under unacclimated aerobic aqueous conditions (Mackay et al. 1992).
       3.   Water — Reaction of isopropanol with hydroxyl radicals in water is slow; half-lives of 1.09
            yr (CHEMFATE 1995) and 197 days to 22 yr (Mackay et al. 1992) have been estimated.
            Based on an estimate of the unacclimated aerobic aqueous biodegradation rate, the half-
            lives of isopropanol in surface and groundwater were estimated to be 26-168 hr and 48-336
            hr, respectively (Mackay et al. 1992).
       4.   Biota— Isopropanol is subject to biodegradation in activated sludge  systems
            (CHEMFATE 1995). Microbial species including Arthrobacter sp., Achromobacter sp., and
            Alcaligenes faecalis have been shown to be capable of degrading isopropanol (CHEMFATE
            1995). The low log Kow value of 0.05 for isopropanol indicates that bioconcentration and
            bioaccumulation are not likely to be important environmental fate processes (HSDB 1995).

H.  ENVDiONMENTAL FATE

    A. Environmental Release
       For the production of lithium hydroxide, lithium ore is heated with limestone to about 1000°C;
       water leaching of the kiln product yields lithium hydroxide. Lithium hydroxide is used as a CO2
       absorbent in space vehicles and submarines, as a storage battery electrolyte, in lubricating
       greases, and in ceramics (Beliles 1994a).

       Releases of lithium to the environment are most likely in the form of inorganic salts or oxides
       (Beliles 1994a). Lithium hydroxide is not listed on the EPA's TRI, requiring certain U.S.
       industries to report on chemical releases to the environment (TRI93 1995).

       4.   Biota — The Log Pow (equivalent to a log Kow) for nitrobenzene sulfonic acid, sodium salt,
            is-2.61; therefore, no significant bioaccumulation is expected (Greim et al. 1994).

II.  ENVIRONMENTAL FATE

    A. Environmental Release
       Magnesium carbonate occurs naturally as magnesite (HSDB 1995). The "cold" operations in the
       magnesite industry, mining and processing of raw material and clinker, and brick preparation,
       are characterized by a high dust content in the working environment with only insignificant
       amounts of solid particles escaping into the atmosphere (Reichrtova and Takac 1992).
       Magnesium carbonate is not one of the chemicals reported to the TRI by certain types of U.S.
       industries.

    B. Transport
       No specific information was found in the secondary sources searched regarding the transport of
       magnesium carbonate. It is, however, moderately soluble in water and would be expected to
       move through the environment.
                                                                                     DRAFT

    C. Transformation/Persistence
       1.   Air— No information was found in the secondary sources searched regarding the
            transformation/persistence of magnesium carbonate in air.  It is, however, moderately
            soluble in water and would be expected to deposited in rainwater.
       2.   Soil— No information was found in the secondary sources searched regarding the
            transformation/persistence of magnesium carbonate in soil.
       3.   Water— Magnesite occurs  in seawater, seawater bitterns, and well brines. In fresh water,
            dissolved magnesium salts (along with calcium salts) are responsible for the hardness of
            water (Beliles 1994b). Magnesium carbonates comprise a significant fraction of the
            sediments of selected lakes and streams studied in the upper Qu'Appelle River basin in
            southern Saskatchewan, Canada (Oscarson et al. 1981).
       4.   Biota—  No specific information was found in the secondary sources searched regarding
            the transformation/persistence of magnesium carbonate in biota.

II. ENVIRONMENTAL FATE

   A.  Environmental Release
       Methanol ranked third in the U.S. among all chemicals for total releases into the environment in
       1992. Of the total released, 195 million pounds were into the atmosphere, 43.5 million pounds
       were into surface  and ground waters, and 3.3 million pounds were onto land (TRI92 1994).
       Methanol detected in the air from Point Barrow, Alaska averaged 0.77 ppb (CHEMFATE 1995).
       Ambient concentrations from Stockholm, Sweden, ranged from 3.83 to 26.7 ppb while
       concentrations from two remote locations in Arizona were 7.9 and 2.6 ppb (HSDB 1995).  In one
       survey, methanol  was detected in drinking waters from 6 of 10 U.S. cities (HSDB 1995) but
       levels were not included. The chemical has also been detected at a level of 22 ppb in rainwater
       collected from Santa Rita, Arizona (HSDB 1995).

                                                                                   DRAFT

-------
APPENDIX C
    B. Transport
       The miscibility of methanol in water and a low Koc of 9 indicate that the chemical will be highly
       mobile in soil (HSDB 1995).  Volatilization half-lives from a model river and an environmental
       pond were estimated at 4.8 days and 51.7 days, respectively (HSDB 1995). Methanol can be
       removed from the atmosphere in rain water (HSDB 1995).

    C. Transformation/Persistence
       1.  Air — Once in the atmosphere, methanol exists in the vapor phase with a half life of 17.8
           days (HSDB  1995). The chemical reacts with photochemically produced hydroxyl radicals
           to produce formaldehyde (HSDB 1995).  Methanol can also react with nitrogen dioxide in
           polluted air to form methyl nitrite (HSDB 1995).
       2.  Soil — Biodegradation is the major route of removal of methanol from soils. Several
           species of Methylobacterium and Methylomonas isolated from soils are capable of utilizing
           methanol as a sole carbon source (CHEMFATE 1995).
       3.  Water — Most methanol is removed from water by biodegradation. The anaerobic
           degradation products methane and carbon dioxide were detected from aqueous cultures of
           mixed bacteria isolated from sewage sludge (CHEMFATE  1995).  Aerobic, gram-negative
           bacteria (65 strains) isolated from seawater, sand, mud, and weeds of marine origin utilized
           methanol as a sole carbon source (CHEMFATE 1995). Aquatic hydrolysis, oxidation, and
           photolysis are not significant fate processes for methanol (HSDB 1995).
       4.  Biota — Bioaccumulation of methanol in aquatic organisms is not expected to be significant
           based on an estimated bioconcentration factor of 0.2 (HSDB 1995).

II. ENVIRONMENTAL FATE

    A. Environmental Release
        /7-Toluene sulfonic acid is manufactured for use as a chemical intermediate in the synthesis of
        dyes, antidiabetic drugs, chemicals used in detergents, and in the synthesis of other organic
        chemicals (Budavari et al. 1989; HSDB 1995).  The exposure of humans to/7-toluene sulfonic
        acid is primarily by dermal contact or inhalation during the manufacture or use of the chemical
        in occupational settings (HSDB 1995). Due to its high water solubility (about 67 g/100 mL),
        exposure may also occur in drinking water. p-Toluene sulfonic acid has been detected
        qualitatively in lowland river water and in groundwater in Britain (HSDB 1995).  Based on a
        1983 National Institute for Occupational Safety and Health (NIOSH) National
                                                                                               DRAFT

-------
 APPENDIX C
        Occupational Hazard Survey, 16,526 workers are potentially exposed top-toluene sulfonic acid
        in the U.S. (HSDB 1995).

    B.  Transport
        Because of its water solubility, p-toluene sulfonic acid is expected to be highly mobile in soils
        and leach rapidly into ground waters. Once in the water, the chemical should not move into the
        atmosphere or onto sediments, but will degrade slowly (HSDB 1995).

    C.  Transformation/Persistence
        1.   Ak — Very small amounts of p-toluene sulfonic acid enter the atmosphere from water
            solutions or from the involatile solid.  Once in the air, it rapidly reacts with hydroxyl
            radicals resulting in a half-life of about 2 days (HSDB 1995).
        2.   Soil — Specific studies on the transformation/persistence of p-toluene sulfonic acid in the
            soil were not available; however, p-toluene sulfonic acid is expected to rapidly leach from
            the soil into ground water because of it's high solubility. It is not expected to volatilize into
            the atmosphere  from the soil (HSDB 1995). Although biodegradation is known to occur in
            water (see H.C.3.), specific information on the biodegradation of p-toluene sulfonic acid in
            the soil is not available (HSDB 1995).
        3.   Water—p-Toluene sulfonic acid primarily enters the environment in wastewater from its
            production and  use. It is ionized in solution and does not significantly transfer into the
            sediment or into the atmosphere from the aquatic environment (HSDB 1995). It does not
            absorb light above 290 nm in solution and will not photodegrade or react with water under
            environmental conditions (HSDB 1995). Biodegradation is highly dependent on the
            presence of the  proper acclimated microbial populations. Complete (100%) degradation in
            a few days was  reported with activated sludge, whereas no degradation was seen for up to
            64 days  in the absence of activated microorganisms (HSDB 1995). Pseudomonas bacteria
            have been isolated from sludge and river water that can utilize p-toluene sulfonic acid as a
            sole carbon and sulfur source (CHEMFATE 1995; Kertesz et al. 1994).
        4.   Biota — Although no specific data are available, p-toluene sulfonic acid is not expected to
            bioconcentrate since it is highly water soluble and ionized in solution (HSDB 1995).
            Experiments with Ricinus commimis L. (castor bean) have shown that plants absorb and
            transport p-toluene sulfonic acid to the leaves (Bromilow et al. 1993); however, it is not
            expected to bioconcentrate in food products (HSDB 1995).

II.  ENVIRONMENTAL FATE

    A. Environmental Release
       Palladium occurs in the earth's crust, at the concentration of 0.2 ppm, in association with the rare
       metals of Group VIII (platinum, ruthenium, rhodium, osmium, and iridium) (Venugopal and
       Luckey 1978; Amdur et al. 1991). The release of palladium to the environment may occur as a
       result of the mining, refining, fabrication, and use of the metal (Seiler and Sigel 1988).
       Palladium has been incorporated into catalysts used to control emissions in automobile exhausts;
       however, the minute quantities emitted are in a biologically inert form (Seiler and Sigel 1988).
       No significant concentrations were detected near busy highways following 10 years of this use
       (Seiler and Sigel 1988).

II.  ENVIRONMENTAL FATE

    A.  Environmental Release
        Phenol-formaldehyde (PF) copolymer is used in a wide variety of products including wood
        composites (plywood, particleboard, fiberboard), molding materials (in appliances, electric
        controls, telephones, and wiring services), and as a binder for thermal and sound insulation
        materials (e.g., glass fibers and mineral wool) (Opresko 1991). There are no reports of any
        detrimental toxic effects from cured phenolic resins; therefore, the greatest hazards associated
        with these  substances is expected to occur during the manufacture, processing, and handling of
        the uncured resin (Opresko 1991). However, loss of both phenol and formaldehyde has been
                                                 C-73
                                                                                               DRAFT

       observed for many months after fabrication of foam insulation for refrigerators (Opresko 1991).
       Phenol was identified as one of a number of volatile organic compounds found in indoor air as a
       result of emissions from construction and interior finish materials and adhesives used in such
       products (Opresko 1991). A study on workers exposed to phenolic resin fumes for periods of
       less than 1 year to more than 5 years reported PF component levels of 7-10 mg phenol/m3 and
       0.5-1.0 mg formaldehyde/m3 (Opresko 1991). Most environmental release of PF components
       would likely come from such manufacturing operations. Both monomeric components of PF
       copolymer, phenol and formaldehyde, have been profiled separately (U.S. EPA 1995a,  1996a).

   B.  Transport
       No information was found in the secondary sources searched regarding the environmental
       transport of PF copolymer.  Cured PF resin is a water insoluble solid and would not be a likely
       groundwater contaminant. Offgassing of PF component monomers during processing and, to a
       lesser extent, after curing would be the most probable mode of environmental transport.

   C.  Transformation/Persistence
       1.    Air — No information was found in the secondary sources searched regarding the
            transformation/persistence of PF copolymer in air.
       2.    Soil — PF copolymer is highly resistant to biological decay (Harris and Sarvadi 1994).
            This fact, coupled with its low water solubility, suggest that PF copolymer would be
            persistent in soil.
       3.    Water — No information was found in the secondary sources searched regarding the
            transformation/persistence of PF copolymer in water. Because of its very low water
            solubility, cured PF copolymer is not likely to be a contaminant of groundwater.
       4.    Biota — No information was found in the secondary sources searched regarding the
            bioaccumulation of PF copolymer.

II. ENVIRONMENTAL FATE

    A. Environmental Release
        Of the total 206.6 million pounds of phosphoric acid released into the environment in 1992, as
        reported to the TRI by certain types of U.S. industries, 1.2 million pounds were released into the
        atmosphere, 158.7 million pounds were released into ground or surface waters, and 46.7 million
        pounds were released onto the land (TRI92 1994).
                                                                                                DRAFT

-------
 APPENDIX C
    B.  Transport
        When spilled onto soil, phosphoric acid will infiltrate downward, the rate being greater with
        lower concentrations because of reduced viscosity. Upon reaching the groundwater table,
        phosphoric acid will move in the direction of the groundwater flow (HSDB 1995).

    C.  Transformation/Persistence
        1.   Ak — Phosphoric acid may be present in air as a mist or a vapor, but it exists primarily as a
            mist because of its low volatility and its affinity for water (IARC 1992).
        2.   Soil — During transport through soil, phosphoric acid will dissolve some of the soil
            material, in particular carbonate based materials. The acid will be neutralized to some
            degree with adsorption of the proton and phosphate ions also possible. However significant
            amounts of acid will remain for transport to groundwater (HSDB 1995).
        3.   Water — Upon reaching groundwater, a contaminated plume will be produced with dilution
            and dispersion serving to reduce the acid concentration (HSDB 1995). However, while
            acidity may be reduced readily by natural water hardness minerals, the phosphate may
            persist indefinitely (HSDB 1995).
        4.   Biota — No information was found in the secondary sources searched regarding the
            transformation/persistence of phosphoric acid in biota.  Phosphoric acid is a natural
            constituent of many fruits and their juices (HSDB 1995).

    A.  Environmental Release
        Potassium and sodium cyanide are used in the extraction of gold and silver ores; electroplating;
        metal cleaning; as insecticides and fumigants; in heat treatment of metals; and as raw materials
        in the manufacture of dyes, pigments, nylon, and chelating agents (ACGIH 1991).  In 1993,
        releases of cyanide compounds to environmental media, as reported to the TRI by certain types
        of industries, totaled about 3,291,307 pounds.  Of this amount, a total of 898,728 pounds was
        released to the atmosphere, 97,666 pounds to surface waters, 2,288,870 pounds to underground
        injection, and 6,043 pounds to land (TRI93 1995).  Potassium and sodium cyanide are not
        reported separately.

    B.  Transport
        Potassium and sodium cyanide release hydrocyanic acid (HCN) to the environment. HCN is
        expected to volatilize from aquatic media and soils (U.S. EPA 1984c).  Cyanide has the potential
        to be transported in air over long distances from its emission source. Alkali cyanides can be
        removed from air by both wet and dry deposition (ATSDR 1995). Because of their high water
        solubility and low sorption characteristics, cyanides are expected to leach through soils into
        groundvvater (U.S. EPA I985c).

    C.  Transformation/Persistence
        ].   Air — Most cyanide in the atmosphere is likely present as HCN gas, but small amounts of
             metal cyanides may be present as particulate matter in air. HCN slowly reacts with
             hydroxyl radicals in the air; the calculated half-life for this reaction is approximately 11
             years, indicating no significant  loss to the troposphere.  Physical transfer, such as wet and
             dry deposition, may dominate the fate of cyanides in the atmosphere.  Considering the water

     solubility of alkali cyanides, wet deposition appears to be more important process (U.S.
     EPA 1984c).
 2.   Soil — In soils, the fate of cyanides is pH dependent.  In acidic soils, the loss of HCN
     through volatilization may be the predominant mechanism of loss from soil surfaces. In
     subsurface soils, cyanides that are present at low concentrations (below the toxic levels for
     microorganisms) may undergo some microbial degradation (U.S. EPA 1984c). Because of
     their low soil sorption characteristics and high water solubility of cyanides, some may leach
     through the soil. However, cyanides have been rarely detected in groundwater.  In basic
     soils, the mobility of cyanides is expected to be greatly restricted (U.S. EPA 1984c).
 3.   Water— The alkali metal salts, such as sodium and potassium cyanide, are very soluble in
     water and the resulting cyanide ions readily hydrolyze with water to form HCN.  The extent
     of HCN formation is mainly dependent upon water temperature and pH.  At 20°C and a pH
     of 8 or below, at least 96% of free cyanide exists as HCN (U.S. EPA 1980).  Since the pH
     of most natural waters ranges between 6 and 9, a large percentage of cyanides will be
     present in the form of HCN which readily volatilizes from water. Cyanides can be
     biodegraded at low concentrations in water by single and mixed organisms. Both aerobic
     and anaerobic microbial degradation of cyanides during sewage treatment plant operations
     have been demonstrated (U.S. EPA  1985c).
 4.   Biota — Potassium and sodium cyanide are not expected to bioaccumulate in aquatic
     organisms (U.S. EPA 1984c).
                                                                                 DRAFT

    A.  Environmental Release
        Silver is a naturally occurring element that is present in the earth's crust at an average
        concentration of about 0.1 ppm and at about 0.3 ppm in soils (ATSDR 1990c). It is also present
        in unpolluted freshwater at concentrations up to 0.5 ppm and in seawater at about 0.01 ppm
        (HSDB 1996). Silver is released into the environment from mining and recovery processes, and
        industrial production processes. It is released into the atmosphere during refuse incineration and
        from burning of coal and petroleum products.  Silver and silver compounds are also released
        from consumer products (ATSDR 1990c).  Products and uses include photography,
        electroplating, electrical conductors, dental alloys, solder and brazing alloys, paints, jewelry,
        coins, and mirror construction (Faust  1992a). The largest source of silver release through
        consumer products is photographic material.  Silver in the form of silver iodide has been used as
                                                                                              DRAFT

        cloud seeding material (ATSDR 1990c). Background atmospheric levels of silver measured in
        national parks away from industrialized areas are generally less than 0.2 ng/m3, however, the
        concentration can be much higher near smelter plants (up to 36.5 ng/m3) or in cloud-seeding
        target areas (1.0 ng/m3) (ATSDR 1990c).  Releases into surface waters have resulted in
        concentrations up to 38 ppm found in the Colorado River, and concentrations as high as 5 ppm in
        finished drinking water samples. Sediments in the Genesee River in New York downstream
        from a plant manufacturing photography supplies were found to contain 150 mg silver/kg dry
        weight (HSDB 1996).

        Releases of silver and silver compounds to environmental media in 1993, as reported to the TRI
        by certain types of U.S. industries totaled about 8608 pounds of elemental silver and 57,168
        pounds of silver compounds.  Of these amounts, totals of 7080 pounds silver and 21,623 pounds
        silver compounds were released to the atmosphere, 318 pounds of silver and 9069 pounds of
        silver compounds were released to surface water, 210 pounds silver and 100 pounds silver
        compounds were released in underground  injection, and 1000 pounds silver and 20,376 pounds
        of silver compounds were released to land (TRI93 1995).

    B.  Transport
        Metallic silver released to the atmosphere  as particulate material undergoes deposition to land
        and surface water (ATSDR 1990c). If the particulate material is finely divided (<20^ diameter),
        it can possibly travel long distances before depositing resulting in an enrichment of soil silver
        levels in areas distant from cloud seeding operations or other sources of airborne silver. Large
        particles (>2Q(t diameter) such as released during mining operations are deposited near the
        source (ATSDR 1990c). Transport of silver in surface waters is dependent upon the particular
        chemical form of the element.  Silver can form a number of complexes and salts under certain
        aquatic conditions of pH and reactant availability.  Some compounds precipitate, some adsorb
        onto particulate matter, and some are soluble and may travel long distances in solution. Up to
        90% of the silver detected in rivers was estimated to be in a dissolved form (ATSDR 1990c).
        Silver tends to be removed from well drained soils; however, the pH, oxidation-reduction
        potential, and the presence of organic material can affect the mobility.  Iron and manganese
        complexes can immobilize silver, and organic material adsorbs silver (ATSDR 1990c).

    C.  Transformation/Persistence
        1.   Ajr—Atmospheric silver is in particulate form and is likely to become coated with silver
            oxide, silver sulfide, or silver carbonate before deposition.  Large particles (>20yu) such as
            released during mining operations are deposited near the source, whereas finer particles
            (<20/i diameter) generated by burning refuse or fossil fuels and by cloud seeding can be
            carried long distances before being deposited in precipitation (ATSDR 1990c).
        2.   Soil—Iron and magnesium complexes in the soil tend to immobilize silver and are
            dependent on pH and oxidation-reduction potential of the soil. Organic matter complexes
            with silver and also reduces its mobility. The persistence of silver in soils is also dependent
            on the drainage of the soil and will eventually be removed from well drained  soils (ATSDR
            1990c).
        3.   Water—Silver in water exists primarily as the monovalent ion, which can be combined
            with sulfate, bicarbonate, chloride, and ammonia. It was estimated that about 90% of the
            silver in rivers is in a dissolved form and the remaining 10% is in suspended solids.
            Depending on the pH  and oxidation-reduction conditions, silver can be adsorbed to
            manganese oxide, which will eventually be deposited in sediment.  It may also become
            adsorbed onto humic material and suspended particulates. In the presence of decaying
            animal and plant material, silver precipitates as the sulfide. The sediments in lakes were

     generally found to be about 1000 times higher in silver concentration than the overlying
     waters (ATSDR 1990c).
4.   Biota —Silver does not tend to bioaccumulate in fish (bioaccuraulation factors of 2-10).
     However, it can be adsorbed by marine algae and accumulated. Bioconcentration factors
     for marine algae of 13,000 to 66,000 have been calculated (ATSDR 1990c). Silver is
     absorbed by mussels, clams, and oysters. Bioconcentration factors of 1055 to 7650 have
     been determined for the marine mussel, Mytilus edulis.  Biological half-lives of 26.4 and
     149.1 days have been estimated for the pacific and American oysters, respectively.  It is
     absorbed from the soil by plant roots and accumulates in the leaves from atmosphere
     deposition. (ATSDR 1990c).

    A.  Environmental Release
        Sodium bisulfate is manufactured for use as a solubilizer for minerals, for pickling metals,
        carbonizing wool, bleaching and swelling leather, and in the manufacture of magnesia cements
        (Budavari et al. 1989). It is also used in the agricultural industry as a disinfectant (RTECS
        1995). The total number of individuals occupationally exposed to sodium bisulfate in a National
        Occupational Exposure Survey in 1983 was 151,380 (RTECS 1995).

 B. Transport
    No information on the transport of sodium bisulfate was found in the secondary sources
    searched.  In areas where the chemical is used, it has been found in airborne dusts and in water
    aerosols (JT Baker Inc.  1995; Utell et al. 1982). Due to its high water solubility, about 50 g/100
    mL (Budavari et al. 1989), transport by water is a possibility.

 C. Transformation/Persistence
    1.   Air — No information on the transformation/persistence of sodium bisulfate was found in
         the secondary sources searched.  Aerosols and dusts in industrial settings are controlled by
         exhaust ventilation (JT Baker Inc. 1995).
    2.   Soil — Specific studies on the transformation/persistence of sodium bisulfate in the soil
         were not found in the secondary sources searched; however, sodium bisulfate is likely to
         rapidly leach from the soil into ground water because of its high solubility.  It is a non-
         volatile solid and should not volatize into the atmosphere from the soil, although it may
         become airborne in dust (JT Baker Inc. 1995).
    3.   Water — No studies  on the transformation/persistence of sodium bisulfate in water were
         found in the secondary sources searched. Sodium bisulfate is strongly acidic in water
         solution (Budavari et al. 1989) and, therefore, is subject to neutralization and salt formation
         by water soluble cations.
    4.   Biota — No information on the transformation/persistence of sodium bisulfate in biota was
         found in the secondary sources searched. The water solubility and acidity of sodium
         bisulfate in solution make  bioconcentration unlikely.

    A.  Environmental Release
        Sodium carbonate is a white hygroscopic powder that is strongly caustic (Pierce 1994b). It is
        moderately soluble in water (Budavari et al. 1989).  It is usually encountered as the decahydrate
        (Na2CO3-10H2O), commonly called washing soda or soda ash (Pierce 1994b). Sodium carbonate
        occurs naturally in large deposits in Africa and the U.S. as either the carbonate or trona, a mixed
        ore of equal molar amounts of carbonate and bicarbonate (Pierce 1994b). Naturally occurring
        hydrates include the monohydrate, thermonitrite, and the decahydrate, natron or natrite
        (Budavari et al. 1989). Sodium carbonate is used in the manufacture of glass and sodium salts;
        in soaps and strong cleansing agents; water softeners; pulp and paper manufacture; textile
        treatments; and various chemical processes. Sodium carbonate is not listed on the U.S. EPA's

    A.  Environmental Release
        Sodium chloride (NaCI) occurs in nature as the mineral halite (i.e. salt deposits) and is dissolved
        in the ocean (2.6% concentration) and other bodies of water (HSDB 1996).  It is produced by
        mining, evaporation of brine from underground salt deposits, and evaporation from sea water
        (Budavari et al.  1996).  It is released artificially into the environment as waste from bake houses
        and pickling and canning factories, etc., and in its use as a snow antifreeze or de-icer on
        pathways (HSDB 1996).

B.  Transport
    No information was found on the environmental transport of sodium chloride in the secondary
    sources searched.  Its high water solubility (1 g/2.8 mL water @ 25 °C, Budavari et al. 1996)
    suggests that if it were released into the soil it would be highly mobile (e.g. when dissolved in
    rainfall) and could eventually end up in the groundwater.

C.  Transformation/Persistence
    1.   Air — No information was found on the transformation/persistence of sodium chloride in
        air in the secondary sources searched. Its low reactivity and volatility (HSDB 1996, Sax
        and Lewis 1989) and high water solubility (Chapman and Hall 1996) indicate that any
        sodium chloride released into the air (e.g. from salt mining) would either dissolve in air
        moisture or remain as unchanged particulates that settle out.
    2.   Soil — Sodium chloride is found naturally in the soil as underground rock salt deposits.
        These salt deposits can be dissolved in water because NaCl is highly water soluble
        (Chapman and Hall 1996, Lide 1991). The dissolved sodium chloride can then be either
        recovered above ground, as in solution mining (Perry et al. 1994), or may possibly end up in
        the groundwater (further information was not located in the searched secondary sources).
    3.   Water— Sodium chloride is very soluble in water, being stable in solution for at least 24
        hours at room temperature (NTP 1996, Chapman and Hall 1996, Lide 1991).  No other
        relevant information was located in the secondary sources searched.
    4.   Biota — No information was found on the transformation/persistence of sodium chloride in
        the biota in the secondary sources searched. Its high water solubility indicates that it would
        not appreciably bioconcentrate in the flora or fauna.
                                                                                     DRAFT

        chlorous acid formed from chlorite in aqueous hydrochloric acid solution, but is more commonly
        achieved by the oxidation of chlorite by chlorine or hypochlorous acid (IARC 1991). Chlorine
        dioxide is generated to bleach and  strip textiles; to bleach wood pulp in paper processing; to
        eliminate tastes and odors in drinking water; to reduce loads of adsorbable organic halogenated
        compounds in industrial effluents;  to control microbiological growth in paper mills, oil wells,

    to treat factory wastes; to bleach natural foliage; and to control algae in industrial cooling towers.
    Sodium chlorite is also used in the electronics industry for etching. It is not known to occur
    naturally (IARC 1991).

    Sodium chlorite is used in a small number of water treatment plants to generate chlorine dioxide;
    this may result in a low residual concentration of chlorite in drinking water (IARC 1991).
    Sodium chlorite is not listed on U.S. EPA's TRI, requiring certain U.S. industries to report on
    chemical releases to the environment (TRI93 1995).

II.  ENVIRONMENTAL FATE

    A. Environmental Release
       Sodium hydroxide is a corrosive deliquescent solid available in various solid forms and as
       solutions, usually 45-75% in water. It is a strong alkali that is highly soluble in water (Budavari
       et al. 1989).  When the chemical is dissolved in water, mists are frequently formed and heat is
       released (Pierce 1994b). As the least expensive strong base, sodium hydroxide is widely
       employed in industries such as rayon, cellophane and textiles, pulp and paper,  soap and
       detergents, etching and electroplating, and many others (ACGIH 1991). Although sodium
       hydroxide releases are expected to occur in industrial/occupational settings, no data were found
       in the secondary sources searched. Consumers may be exposed to oven cleaning products that
       contain >5% lye (HSDB 1995).

B.  Transport
    No information on the transport of sodium hydroxide was found in the secondary sources
    searched. Because of its low vapor pressure, sodium hydroxide is not expected to partition to the
    atmosphere in significant amounts. The water solubility suggests that sodium hydroxide would
    leach through soil.

C.  Transformation/Persistence
    No information on the transformation/persistence of sodium hydroxide was found in the
    secondary sources searched.  Low vapor pressure and its water solubility suggest the chemical
    would remain in the aqueous phase.

II.  ENVIRONMENTAL FATE

    A.  Environmental Release
       No data on the release of stannous chloride to the environment were located in the secondary
       sources searched; environmental levels of tin are stated in terms of inorganic tin. Tin is a
       naturally-occurring element found in environmental media and natural foods. Tin and tin
       compounds are not included in the TRI. The most significant releases of inorganic tin are from
       burning of fossil fuels and industrial production and use of tin (ATSDR 1992). The tin content
       of airborne fly ash from coal-burning plants ranged from 7-19 //g/g (ATSDR 1992). Tin in
       waste streams originates primarily from the production of tin cans (Brown 1983, as reported in
       HSDB 1995). Tin also occurs in water stored in coated metal containers and may be released in
       effluents from industrial processes and from municipal sewage (NRC 1977). Human exposure to
       tin is primarily by ingestion of canned food  products (ATSDR 1992).
                                           C-lll
                                                                                     DRAFT

-------
APPENDIX C
       Public water supplies in 42 U.S. cities contained total tin at concentrations of 1.1-2.2 ug/L; water
       from 175 natural sources in west-central Arkansas contained 0.9-30 ug/L total tin (NRC 1977).
       Total tin was below the limit of detection in 56 of 59 samples of river water in the U.S. and
       Canada; the other three values were 1.3, 1.4, and 2.1 ug/L (NRC 1977).  Seawater contains 0.2-
       0.3 i*g/L (NRC 1977). Tin occurs in surface and groundwater at 21% of NPL sites at a
       geometric mean concentration of 50 /ug/L (ATSDR 1992). Ambient soil levels in Canada ranged
       from 1-200 mg/kg total tin (mean 4 mg/kg); the ambient sediment level was 4.6 mg/kg (HSDB
       1995). Tin was detected at hazardous waste sites at a geometric mean concentration of 30 mg/kg
       of soil (ATSDR 1992).

    B. Transport
       Tin released to the atmosphere in the form of particulates would be removed by gravitational
       settling within a matter of days.  In soil, the Sn2+ cation will be adsorbed to some extent.
       Although moderately water soluble, tin in water may partition to soils and sediments; the Sn2+
       ion will also readily precipitate as a sulfide or hydroxide (ATSDR 1992). These characteristics
       would limit mobility.

    C. Transformation/Persistence
       1.   Air — Tin in the atmosphere is usually associated with dust particles; the deposition half-
            life of dust particles is on the order of days (U.S.  EPA  1987c). No information on the
            transformation or degradation of inorganic tin compounds in the atmosphere was found.
       2.   Soil — The Sn2+ cation will be adsorbed by soil to some extent (ATSDR 1992), thereby
            retarding leaching to groundwater. The formation of insoluble salts would also limit the
            amount leaching to  groundwater.
       3.   Water — Sn2+ in oxygen  poor alkaline water will readily precipitate as a sulfide or
            hydroxide (ATSDR 1992); this would limit the amount in  solution or suspension in
            groundwater.  Inorganic tin may be transformed into organometallic compounds; a change
            of valence state  probably does not occur (ATSDR 1992).
       4.   Biota — A log Kow  of-2 to -3 would indicate little potential for bioaccumulation,  but
            reported estimates of the  bioconcentration factors for inorganic tin (valance state not given)
            for marine and freshwater plants, invertebrates, and fish were 100,  1000, and 3000,
            respectively (ATSDR 1992).

II.  ENVIRONMENTAL FATE

    A.  Environmental Release
        Sulfuric acid is a clear, colorless, odorless, oily liquid. It has a high affinity for water,
        abstracting it from the air and many organic substances.  Sulfuric acid is produced in numerous
        grades and strengths. Commercial sulfuric acid contains 93-98% of acid; the remainder is water
        (Budavari et al. 1989).  The primary sources of sulfuric acid in the atmosphere are vehicular
        emissions, combustion sources, explosive manufacture, furnace soot, sulfuric acid manufacture,
        and steel manufacture (U.S. EPA 1984d). Sulfuric acid occurs naturally in the vicinity of
                                                                                              DRAFT
                                                C-l 13

-------
APPENDIX C
       volcanoes, particularly in volcanic gases (HSDB 1995).  Sulfur dioxide in moist air or fog
       combines with the water to form sulfurous acid; the latter is slowly oxidized to sulfuric acid
       (Beliles and Beliles 1993). Based on rain chemistry data measured in southwestern Pennsylvania
       in 1983, an acid deposition budget was estimated as follows: 47%, sulfuric acid in rain; 23%,
       sulfur dioxide deposition without dew; 16%, nitric acid and sulfuric acid in fog and dew; and
       0.5% aerosol dry deposition without dew (HSDB 1995).

       Sulfuric acid can enter the aquatic environment from a variety of sources: in accidental spills
       from train derailments; in wastewaters from mining properties where sulfides are part of the ore
       or the rock being mined; in wastewaters from the steel industry; from the atmosphere; and as a
       decomposition product of effluents containing sulfur, thiosulfate, or thionates (HSDB 1995).

       Sulfuric acid is the most widely used of the strong inorganic acids. Average occupational
       exposures to sulfuric acid mists in pickling, electroplating, and other acid treatment of metals are
       frequently above 0.5 mg/m3, while lower levels are usually found in the manufacture of lead-acid
       batteries and in phosphate fertilizer production (IARC 1992).

       In 1992,  releases of sulfuric acid to environmental media, as reported to the TRI by certain types
       of industries, totaled about 156,809,406 pounds.  Of this amount, 23,721,453 pounds (15%) were
       released to the atmosphere, 32,719,526 pounds (21%) were released to surface water, 98,631,395
       pounds (63%) were released in underground injection sites, and 1,737,032 pounds (1%) were
       released on land (TRI92 1994).

    B. Transport
       Sulfuric acid aerosols in the atmosphere are likely to be removed through wet and dry
       deposition.  Released to soils, most of the sulfuric acid is expected to be removed by reaction
       with inorganic minerals or organic matter in soils.  In highly sandy soil, sulfuric acid probably
       leaches into groundwater (U.S. EPA 1984d).

    C. Transformation/Persistence
       1.   Air— Sulfuric acid is present in the atmosphere in the form of aerosols. In dry weather,
            the aerosol is found  in the sub-0.65 //m particle size fraction,  while under humid conditions,
            it is present in the 0.65-3.6 fj.m particle size range.  Sulfuric acid is a primary source of
            inorganic sulfates in the atmosphere, particularly ammonium  sulfate. Depending on the
            amount of moisture  in the atmosphere, sulfuric acid aerosols may react with organics in the
            atmosphere to form  sulfonates.
       2.   Soil — The majority of sulfuric acid in soils is expected to be removed by reaction with
            inorganic minerals or organic matter in soils.  During transport through the soil,  sulfuric
            acid can dissolve some of the soil material,  in particular carbonate-based materials (HSDB
            1995). In highly sandy soil, sulfuric acid probably leaches into groundwater (U.S. EPA
            1984d).
       3.   Water — In aquatic media of about pH >7,  sulfuric acid reacts with carbonate, bicarbonate,
            or hydroxides in the sediment or suspended particles, with the formation of sulfates. Since
            the majority of sulfates, with the exception  of lead and calcium, are soluble in water, this
            reaction may mobilize the precipitated metals from the aquatic phase and decrease the pH
            of the solution. In aquatic media of pH <7, at least a part of the sulfuric acid may remain
            ionized in solution and may be mobile (U.S. EPA 1984d).
       4.   Biota — No information on the transformation/persistence of sulfuric acid in biota was
            found in the secondary sources searched.

 H.  ENVIRONMENTAL FATE

     A.  Environmental Release
         No information on environmental releases of tartaric acid was found in the secondary sources
         searched. Tartaric acid is widely used in foods, soft drinks, wine, cleaners, textile printing,
         Pharmaceuticals, etc. and is freely water-soluble, so small quantities are likely to be released into
         the water supply, soil and eventually the groundwater from personal and commercial use and
         production.
                                                                                                 DRAFT

-------
 APPENDIX C
     B. Transport
        No information on the environmental transport of tartaric acid was found in the secondary
        sources searched. Its high water solubility (139 g/100 mL @ 20°C; Budavari et al. 1996)
        suggests that if it did volatilize it could be removed from the atmosphere by rainfall, and if it
        were released onto soil it would likely be mobile and may end up in the groundwater.

     C. Transformation/Persistence
        1.   Air- Tartaric acid is reported to be stable to air and light (Budavari et al. 1996); no other
             information was found in the secondary sources searched.
        2.   gpi'l - No information regarding the transformation/persistence of tartaric acid in soil was
             located. Its high water solubility suggests it would be highly mobile in soil and could enter
             the groundwater.
        3.   Water —No information on the transformation/persistence of tartaric acid in water was
             found in the secondary sources searched.  Being a strong organic acid (Budavari et al.
             1996), it is expected to dissociate into its ion components when in water.
        4.   Biota - No  information on the transformation/persistence of tartaric acid in the biota was
             found in the secondary sources searched.  Its high water solubility indicates that it would
             not appreciably bioconcentrate in the flora or fauna.

H.  ENVIRONMENTAL FATE

    A.  Environmental Release
        No information was found in the secondary sources searched regarding the environmental release
        of Na4EDTA.  The chemical is probably released to air, water, and soil from industries that
        manufacture and use it, from the use of pesticide formulations that contain it, and from the
        disposal of Pharmaceuticals and other consumer products that contain it.

    B.  Transport
        No information was found in the secondary sources searched regarding the environmental
        transport of Na4EDTA. The vapor pressure for Na4EDTA (0.24 x 102 torr [CHEMFATE 1995])
        suggests that the chemical is moderately volatile and may undergo volatilization from soil and
        water surfaces. The high water solubility of Na4EDTA suggests possible leaching of the
        chemical through the soil  to groundwater.
                                                                                            DRAFT

APPENDIX C
    C. Transformation/Persistence
       1.   AlC — Estimated half-lives for the reaction of Na4EDTA with RO2, OH, and O3 are 2200
            years, 8 minutes, and 1 day, respectively (CHEMFATE 1995). This suggests that
            Na4EDTA in the atmosphere may undergo significant reaction with photochemically-
            generated hydroxyl radicals and ozone.
       2.   Soil—Na4EDTA released to the soil would form soluble metal chelates with most divalent
            and trivalent metal lie ions (HSDB 1995).
       3.   Water — The reaction of Na4EDTA with OH in air (CHEMFATE 1995) suggests that the
            chemical may also react with photochemically-generated hydroxyl radicals in water.
       4.   Biota — No information was found in the secondary sources searched regarding the
            persistence or biomagnification of Na4EDTA in biota.

H.  ENVIRONMENTAL FATE

    A.  Environmental Release
        No information was found in the secondary sources searched to indicate the specific amount of
        triethanolamine released to the environment in any given year. Approximately 100,000 -
        500,000 tons/year of the chemical are produced worldwide (U.S. EPA 1995b).  Although the
        production of triethanolamine is tightly controlled, a worst case estimation of production loss by
        industry to the environment is 0.5%. Release can also occur during the use of the chemical as a
        metal working/cutting fluid, as an additive to cement, as an intermediate in surfactant
        production, or in the manufacture of textile auxiliaries (U.S. EPA 1995b).

    B.  Transport
        Because of the high water solubility and low octanol-water coefficient of triethanolamine, the
        chemical will likely partition into water. Although no data were found for the KOW, adsorption
        onto soils is unlikely and leaching of the chemical into ground water is expected. The low vapor

       pressure and low Henry's Law Constant indicate that volatilization to the atmosphere will be
       negligible.

    C. Transformation/Persistence
       1.   Air — The half-life for triethanolamine reaction with photochemically produced hydroxy
            radicals was estimated at 4 hours with a rate constant of 10.4 x 10"11 cm3/molecules-sec and
            assuming an average hydroxyl concentration of 5 x 10s molecules/cm3 (HSDB 1995). The
            chemical will also be removed from the atmosphere in precipitation (HSDB 1995).
       2.   Soil — Triethanolamine will be biodegraded rapidly in soils, following acclimation, with a
            half-life of days to weeks. Removal from soils also occurs through leaching (HSDB 1995).
       3.   Water — Triethanolamine is rapidly degraded in water following acclimation. In a batch
            system using activated sludge, the chemical was 89% degraded in 14 days following a 3 day
            acclimation period (CHEMFATE 1995).  Other tests showed increases in theoretical
            biological oxygen demand (BOOT) of 66% and 69% (sea water) in 20 days using sewage
            inoculum (CHEMFATE 1995; HSDB 1995).
       4.   Biota — Based on the low estimated bioconcentration factor and high water solubility of
            triethanolamine, the chemical is expected to have a low potential for bioaccumulation in
            aquatic organisms.

H.  ENVIRONMENTAL FATE

    A.  Environmental Release
        Sodium citrate is a solid with a cool, saline taste that is soluble in water (Fisher Scientific 1985).
        It is used in soft drinks, frozen desserts, meat products, cheeses, and as a nutrient for cultured
        buttermilk; in photography; in detergents; as a sequestrant and buffer; as an anticoagulant for
        blood withdrawn from the body; and in the removal of sulfur dioxide from smelter waste gases
        (Lewis 1993).  Medicinally, sodium citrate is used as expectorant and systemic alkalizer.
        Sodium citrate is a chelating agent and has been used to facilitate elimination of lead from the
        body (Osol 1980).

                                                                                               DRAFT

-------
APPENDIX C
       No data were found on the environmental releases of sodium citrate. The chemical is not listed
       on U.S. EPA's TRI, requiring certain U.S. industries to report on chemical releases to the
       environment (TRI93 1995).  The chemical could potentially enter the environment when used for
       the removal of sulfur dioxide from smelter waste gases.

    B.  Transport
       No data were found on the environmental transport of sodium citrate in the secondary sources
       searched.  Its water solubility suggests that the sodium citrate would remain in the water phase.

    C.  Transformation/Persistence
       No data were found on'the transformation/persistence of potassium bisulfate in the secondary
       sources searched.

 H.  ENVIRONMENTAL FATE

     A.  Environmental Release
         No information was found in the secondary sources searched regarding the environmental release
         of vanillin. The chemical occurs naturally in vanilla, potato parings, and Siam benzoin (Budavari
         etal. 1996).

     B.  Transport
         No information was found in the secondary sources searched regarding the environmental
         transport of vanillin. The vapor pressure (2.2 x 10'3 mm Hg [HSDB 1996]) for the chemical
         indicates that little volatilization from soil or water could occur. Vanillin is soluble in water (1
         g/100 mL [Budavari et al.  1996]) and may move through the soil, possibly to groundwater.
                                                                                               DRAFT

-------
 APPENDIX C
     C. Transformation/Persistence
        !•   Ak— Vanillin oxidizes to some extent when exposed to moist air and is "affected" by light
             (Budavari et al. 1996). Vanillin absorbs UV light at wavelengths of 308 and 278 nm
             (Kirwin and Galvin 1993), suggesting that phototransformation is possible. Decomposition
             of vanillin under strict anaerobic conditions has been observed (HSDB 1996).
             .Sp'l,—No information was found in the secondary sources searched regarding the fate of
             vanillin in soil.
             Water—No information was found in the secondary sources searched regarding the fate of
             vanillin in the aquatic environment. Based on its absorption of UV light at wavelengths of
             308 and 278 nm, vanillin in surface water could undergo some phototransformation.
             Biota— No information was found in the secondary sources searched regarding the
             bioaccumulation of vanillin.

 RE:         MODELING WORKER INHALATION EXPOSURE
I.
INTRODUCTION
This technical memorandum is submitted for review by the RM2 work group. Air transport
models to estimate worker inhalation exposure to chemicals from printed wiring board (PWB)
making holes conductive (MHC) lines are presented here for review and comment. The purpose
is to reach agreement on our technical approach before proceeding with further analysis.

Three air transport models will be required to estimate worker exposure:

•    Volatilization of chemicals induced by air sparging.

•    Aerosol generation induced by air sparging.

•    Volatilization of chemicals from the open surface of MHC tanks.

The total transport of chemicals from the air-sparged baths will be determined by summing the
releases calculated using each of the three models described above.  Air-sparged baths include
the electroless-copper baths and some cleaning tanks.  Only the third model will be applied to
determine the atmospheric releases of chemicals from unsparged baths. This document includes
a review of the relevant literature, descriptions of the models, and examples demonstrating the
proposed use of the models. The results of the model calculations will be compared to available
occupational monitoring data.

II.     VOLATILIZATION OF CHEMICALS FROM AIR-SPARGED PWB
       MANUFACTURING TANKS

Mixing in plating tanks, e.g., the electroless copper plating tank, is commonly accomplished by
sparging the tank with air. This is similar to aeration in wastewater treatment plants, and the
volatilization of chemicals from these plants has been the focus of recent research. The
volatilization models used in that research are based on well accepted gas transfer theory,
discussed below.
Background

Volatilization of chemicals from water to air has been investigated by many researchers (Liss and
Slater, 1974; Smith et al, 1980; Roberts, 1983; Peng et al, 1993). In PWB manufacturing,
volatilization due to air sparging of process tanks is expected to be one of the main pathways for
contaminant transfer to the air. In bubble aeration systems, the volatilization rate is dependent
upon the volumetric gas flow rate, partial pressure of the gas, and the mass transfer rate
coefficient (Matter-Muller, 1981). The volatilization characteristics for different diffuser types
and turbulent conditions were evaluated by Matter-Muller (1981), Peng (1995), and Hsieh
(1994).

Volatilization from aerated systems has been mainly quantified using the two-film theory (Cohen
et al, 1978; Mackay and Leinonen, 1975). This work is discussed below and is used to model
chemical transfer rates from air-sparged PWB process tanks. The main assumption of the theory
is that the velocity at a fluid interface is zero. Molecular diffusion across the interfacial liquid
film is the limiting factor for mass transfer to the air, and it is used to develop a simple equation
relating the overall mass transfer coefficient to the diffusion coefficient of the chemical in water.

The two-film model of gas transfer was expanded to include mass transfer in diffused aeration
systems (Matter-Muller et al., 1981). Matter-Muller et al. assumed that the system was
isothermal, hydraulic conditions were steady, and that pressure and volume changes within the
bubbles were negligible. Further, an overall mass transfer coefficient was applied to represent
transfer of contaminants to the bubble as they rose through the homogeneous liquid volume.
Parker (1993) demonstrated that liquid-phase concentration can be assumed constant during the
rise time of the bubble. Under these assumptions, Matter-Muller et al. derived the following
relationship predicting the mass transfer rate from an aerated system:
  1-exp —

The overall mass-transfer coefficient is defined as the inverse sum of the reciprocals of the liquid
and gas-phase mass transfer coefficients; but, because molecular diffusion of oxygen and
nonpolar organic substances is 103 times greater in air than in water (Matter-Miiller et al., 1981),
it is set equal to the liquid phase coefficient only. The mass transfer coefficient of a chemical can
then be related to oxygen using the following equation:

Matter-Muller (1981) concluded that surfactants do not significantly alter the rate of
volatilization from the water.  Some agents did lower the overall mass transfer coefficient, but
most showed no appreciable difference. This was attributed to an increase hi the specific
interfacial area, a, when the interfacial energy, or mass transfer coefficient, was decreased. The
transfer rate of volatile organic compounds (VOCs) was found to depend heavily upon the type
of aerators used, and the degree of saturation of the bubbles rising through the liquid.

        AEROSOL GENERATION FROM BATHS MIXED BY SPARGING WITH AIR
Aerosols or mists have been identified as a major source of contaminants released by
electroplating baths to the atmosphere (Burgess 1981) and should be investigated as a potential
source of contaminants from electroless baths. At least two sources of aerosols exist in
electroplating baths: 1) aerosols generated due to liquid dripping from parts as they are removed
from the bath (drag-out drips) and 2) aerosols generated due to bursting of the bubbles at the
surface. Drag-out drips are insignificant compared to other sources of aerosols (Berglund and
Lindh, 1987; Cooper et al.).

Bubbles in electroplating baths can originate from the dissociation of water at the electrode, or
mixing of the bath via air sparging. Bubbles in other plating baths (e.g., electroless plating
baths) can originate from reactions in the bath or mixing of the bath via air sparging. The rate of
                                                                                  DRAFT

APPENDIX D
generated by water dissociation are typically smaller than those generated by air sparging;
therefore, aerosol generation in electroless plating processes may be less significant than in
electroplating operations. The focus of this memo is aerosols generated by air sparging. Except
for the conductive polymer and non-formaldehyde electroless alternatives, MHC processes in
PWB manufacturing do not use electroplating and therefore would not dissociate water to form
gas bubbles. Information collection is continuing to allow prediction of aerosol formation in
MHC processes that do have an electroplating step.  Importantly, Berglund and Lindh (1987)
report that aerosol generation from electroplating tanks is greatly reduced by sparging; the
relatively large air bubbles formed during air sparging coalesce the smaller bubbles formed by
hydrolysis and electroless plating reactions.

To estimate the emission of contaminants resulting from aerosols, the rate of aerosol generation
and the concentration of contaminant in the aerosol are required. Limited information
concerning the rate of aerosol formation was found in the literature.  The following sources were
consulted:

•        U.S. EPA (1991). Chemical Engineering Branch Manual for the Preparation of
         Engineering Assessments.

•        Chemical Abstracts, 1986 to date.

•        Current and past text books in air pollution, chemical engineering, and water and
         wastewater treatment.

•        Perry's  Handbook (1984) related to entrainment in distillation trays.

•        The last five years of Water Environment Research and ASCE Journal of the
         Environmental Engineering Division.

•        A title key-word search of holdings in the library of the University of Tennessee.

•        The ASPEN model commonly used for modeling chemical manufacturing processes. (It
         was found that any aerosol formation routines within ASPEN would be relevant to
         entrainment in devices such as distillation trays and not relevant to sparging of tanks.)

•        The manager of the USEPA Center for Environmental Assessment Modeling in Athens,
         Georgia, as well as an expert hi the Air and Energy Lab - Emission Modeling Branch hi
         North Carolina.

In this work, the aerosol formation rates will be predicted based upon limited measurements of
aerosol generation in electroplating (Berglund and Lindh,  1987) and other air-sparged baths
(Wangwongwatana et al., 1988; Wangwongwatana et al., 1990) found in the literature.

Berglund and Lindh (1987) developed several graphs relating aerosol generation to air sparging
rate (Figure la), bath temperature (Figure Ib), air flow rate above the bath (Figure Ic), and

       = distance between the bath surface and tank rim correction factor
Wangwongwatana et al. (1988) presented figures relating the number of aerosol droplets
generated as a function of air flow rate, bubble rise distance, bubble size, and colloid
concentration (Figure 2).  Droplet size distribution measurements by these researchers indicate
volume mean diameters of 5 to 10 um. The aerosol generation rate can be calculated using the
following equation:
                                                                                     (10)
where:   Cd     = droplet concentration (I'3)
         Vd     = droplet volume (1)
         A      = bath area (I2)
Contaminants may be present in aerosols at elevated concentration relative to the bath
concentration. Colloidal contaminants may be collected on the bubble surface as it rises through
the bath. As the bubble bursts, the contaminants on the bubble surface are incorporated into
aerosols. Wangwongwatana et al. (1990) report that in their experiments about one in two
aerosols contain polystyrene latex spheres, compared to about one in 250 expected based upon
the concentration of latex sphere in the bath.  Organic contaminants may also partition at the air-
water interface.  A correlation for the water-interface partitioning coefficient for nonpolar
compounds, klw, defined as the  ratio of the mass of contaminant per unit area of interface to the
mass of contaminant per unit volume of water is given by Hoff et al. (1993):
         log £/(J,=-8.58  -0.769 log C*

Only a small fraction of the bubble interface will be ejected as aerosols. It may be calculated
from the following equation:
                                                                                   (14)

IV.      VOLATILIZATION OF CHEMICALS FROM THE OPEN SURFACE OF MHC
         TANKS

Most plating tanks have a free liquid surface from which chemicals can volatilize into the
workplace air. Air currents across the tank will accelerate the rate of volatilization. The model
presented in the Chemical Engineering Branch Manual for the Preparation of Engineering
Assessments (CEBMPEA) (USEPA, 1991) has potential application in this case. Some
limitations of the model should be pointed out. The model was developed to predict the rate of
volatilization of pure chemicals, not aqueous solutions.  The model was also validated using pure
chemicals. As a result, the model implicitly assumes that mass transfer resistance on the gas side
is limiting. The model may fail in describing volatilization of chemicals from solutions when
liquid-side mass transfer controls.

CEBMPEA models the evaporation of chemicals from open surfaces using the following model:

        Fy,0 = 2 cL,y Hy A [Dy,airvz/(7tz)F                                              (16)

where:  Fy>0    = volatilization rate of chemical y from open tanks (m/t)
        Dy air   = molecular diffusion coefficient of chemical y in air (!2/t)
        vz     = air velocity (1/t)
        z      = distance along the pool surface (1)

The value of vz recommended by CEBMPEA is 100 ft-min"1.  The value of Dy air can be estimated
by the following formula (USEPA, 1991):
Dvair = 4.09xlO-5 T1-9 (1/29
                                       -5 M-°-33/Pt

        T      = air temperature (K)
        M     = molecular weight (g/mol)
        Pt      = total pressure (arm)

This equation is based on kinetic theory and generally gives values of Dy iair that agree closely with
experimental data.

         k

        = room ventilation rate (t1)
        = dimensionless mixing factor
                                                                               (18)
 The mixing factor accounts for slow and incomplete mixing of ventilation air with room air.
 CEBMPEA sets this factor to 0.5 for the typical case and 0.1 for the worst case.  CEBMPEA
 commonly uses values of the ventilation rate Q from 500 fWmin to 3,500 fWmin. Appropriate
 ventilation rates for MHC lines will be chosen from facility data and typical industrial
 recommendations.

Transport in aerosols

The aerosol generation rate will be estimated using data presented by both Berglund and Lindh
(1987) and Wangwongwatana et al. (1988)

The air sparging rate used in the example (53.8 L/min) must be converted to an equivalent rate in
the experimental apparatus using the ratio of the area of the example bath (0.341 m2) to the area
of the experimental apparatus (0.123 m2). The equivalent rate is 19.4 L/min. The bubble rise

The aerosol generation rates calculated by the two methods agree quite well. The model of
Berglund and Lindh (1987) will be used because it gives a slightly greater generation rate and is
easier to use.

Emission rate from bath. If it is assumed that the formaldehyde concentration in the aerosols is
equal to the bath concentration (7 mg/mL) then the formaldehyde emission rate is:

        Fy,a = (7 mg/mL)-(0.0187 mL/m2/min)-(0.341 m2) = 4.46xlO'2 mg/min

To determine if accumulation of the contaminant at the air- water interface is significant, kiw must
be estimated using Equation 1 1 .  Since formaldehyde is a gas at the temperatures of interest,
interfacial tension data are not available; however, average values of other aldehydes may be
used (Hoff et al., 1993). Calculation of kIW@25°C is summarized below; information was not
available for calculating kiw at other temperatures.

         nz      = 0.508 m/sec
         z      = 0.48 m (shortest tank dimension gives highest mass transfer rate)

The gas side mass transfer coefficient (kg ) in the above model is:

         kg = 2tDy,airvz/(pz)F

                = 0.484 cm/sec

Thibodeaux (1979) reports a value of the liquid side mass transfer coefficient (kj) in large water
bodies of about 6x10"4 cm/sec for wind speeds of 0.5 m/sec. Although not directly applicable to
the current situation, it can be used as a first estimate to determine the potential for liquid film
resistance to control the mass transfer rate.

         Liquid side resistance = Hy/ k, = 3.3xlO"2 sec/cm

         Gas side resistance = l/kg = 2.1 sec/cm

It can be concluded that formaldehyde volatilization from open tanks is controlled by gas-side
mass transfer resistance; therefore, the CEBMPEA equation appears to be valid. It should be
noted that it may be necessary to consider liquid-side mass transfer resistance for chemicals with
larger Henry's constants. In this case the CEBMPEA model would not be valid.

Surprisingly, volatilization due to air sparging is less significant than that from open tanks.
Although the concentration of formaldehyde in the bubbles is high (virtually at  equilibrium with
the formaldehyde concentration in the bath), the volume of air sparged is small compared to the
volume of room air flowing over the top of the tanks.

VH.    COMPARISON OF PREDICTED FORMALDEHYDE CONCENTRATIONS IN
        WORKPLACE AIR TO MONITORING DATA

In this section, the concentrations of formaldehyde in the workplace air predicted by the model
are compared to available monitoring data. The purpose of the comparison is not to validate the
model but to determine if the modeling approach gives reasonable values of formaldehyde
concentration. Model validation would require calculation of formaldehyde concentrations using
the conditions specific to the monitoring sites. Such data are not available.

The results of an OSHA database (OCIS) search of monitoring data for formaldehyde (provided
by OPPT) include 43 measured air concentrations for 10 facilities  in Standard Industrial
Classification (SIC) 3672 (printed circuit boards). The concentrations range from not detected to
4.65 ppmv.  Most of the concentrations (37/42) range from z 0.04 to 0.6 ppmv, with all but one
less than 1.55 ppmv. Cooper et al. report formaldehyde concentrations from three electroless
plating operations measured over a two day period. The mean concentrations ranged from 0.088
to 0.199 ppmv.  The predicted concentration of formaldehyde in the workplace air was 0.263
ppmv.  Thus the predicted value is within the range of concentrations determined by monitoring,
and less than the OSHA time-weighted-average concentration of 0.75 ppmv. The authors
conclude that the results are reasonable.

RE:         SENSITIVITY AND UNCERTAINTY ANALYSIS OF WORKPLACE AIR
             CONCENTRATION MODELS USED IN THE PWB EXPOSURE
             ASSESSMENT
I.
INTRODUCTION
This technical memorandum is submitted to the RM2 Work Group for review and comment.
Sensitivity and uncertainty analyses of the fate and transport models used in predicting
workplace air concentrations of MHC chemicals were performed.  (These air concentrations are
used hi the exposure assessment to estimate worker inhalation exposures.) The model
parameters having the greatest effect on chemical air concentrations in the workplace are
identified. A quantitative uncertainty analysis was also performed. These analyses serve to
pinpoint and validate key parameter assumptions.

II.    METHODS AND RESULTS

Sensitivity Analysis

The first step in this analysis was to determine the parameters in the ah" transport models that had
the largest impact on the workplace chemical air concentrations regardless of parameter
variability. This was done by  independently varying each parameter hi the model by a specific
amount and observing the effect on chemical air concentration. This allows a comparison to be
made between parameter importance in terms of model sensitivity because their effects on
chemical air concentration were obtained independently of the other parameters.

Table 1 lists the parameters that had the greatest effect on workplace air concentration.  Small
changes in some parameters caused the model results to vary widely, indicating a need to
determine the uncertainty associated with these variables. For sparged baths the example
chemical was formaldehyde, and fluoboric acid was used for the unsparged bath analysis. Other

chemicals were observed in the sensitivity analysis to learn whether the effects per chemical
would vary with these parameters. This means that every chemical will not be affected in exactly
the same way when varying parameters, but will exhibit close behavior. This initial sensitivity
analysis was used primarily to select the important parameters for the Monte Carlo analysis to
follow, and as a check for that analysis.

concentration as shown in columns 2, 3, and 4.
2: Percentage increase or decrease hi room air concentration of air-sparged volatiles due to parameter
variation (A x) of 10 percent.
3: Percent increase or decrease in room air concentration of air-sparged nonvolatile (i.e., vapor pressure <
1x1 0 '3 torr) due to parameter variation (A x) of 1 0 percent.
4: Percent increase or decrease in room air concentration of unsparged volatiles due to parameter variation (A
x) of 10 percent.
For example, a 10% increase in bath surface area increases a sparged volatile's workplace air
concentration by 5.9%, while only increasing a sparged non-volatile or salt air concentration by
2.3%. Each parameter listed was also increased by 20% to determine if its relationship to air
concentration was highly nonlinear, but none exhibited a significant trend in this area.
Parameters not listed hi Table 1 exhibited negligible effects on the model (O.001 percent change
hi air concentration).  These negligible parameters are:

•      Bath volume;
•      Surface tension coefficients;
•      Molecular volume;
•      Water densities and viscosities (due to variation of temperature in baths);
•      Sparged bubble diameter; and
•      Correction factors hi the Berglund and Lindh model (see Exposure Assessment Draft,
       1996).

Monte Carlo Analysis

Overview and Approach. After evaluating the sensitivity of the model to each parameter the
next step was to examine model sensitivity and uncertainty using Monte Carlo Analysis. This
was done with a Monte Carlo software package (Crystal Ball, Decisioneering, Inc.) in
conjunction with a spreadsheet program (Lotus 1-2-3).  The air transport equations outlined in
the Exposure Assessment Draft (May 15, 1996) were used with the distributions for each
parameter from the Workplace Practices Survey to perform this Monte Carlo analysis.

Many different methods are available to propagate parameter distributions through a model and
analyze the results.  However, the difficult task of correlating complex nonlinear models and
their parameters with some kind of regression algorithm severely limits the available techniques.
The Latin Hypercube modification of the Monte Carlo method is agreed upon by many
researchers to be the best way to perform a sensitivity/uncertainty analysis of contaminant
transport models. In Latin Hypercube sampling, a probability distribution is divided into
intervals of equal probability, thereby allowing for a more precise sampling routine because the
entire probability range is more consistently represented (Decisioneering, Inc.).  This
probabilistic approach was used to generate a distribution of possible workplace air
concentrations in contrast to a single point estimate.

Table 2 lists the assumptions used for the parameter distributions for the two bath type examples
and describes the sources of information.

Crystal Ball was used to produce two independent Monte Carlo simulations, one for volatiles in
air-sparged baths and one for unsparged baths.  The number of iterations used for each
simulation was 15,000. This was chosen to ensure adequate convergence and stabilization of the
tails on output distributions (based on McKone and Bogen, 1991).  The mass flux contribution
from nonvolatiles in sparged baths is largely negligible and is not included to simplify the Monte
Carlo simulations.

In addition to probability distributions, Crystal Ball calculates the percent contribution each
parameter makes to overall model variance by computing Spearman rank correlation coefficients
between every assumption and model result while the simulation is running.  Spearman rank
correlation coefficients differ from traditional linear regressions because ranks are assigned to
observations and then substituted for the actual numerical values in the correlation formula. This
correlation has distinct advantages over a simple linear regression.  The relationship between
variables is no longer assumed to be linear, and no assumptions of normality are made
concerning the distributions of the variables as the relationship is nonparametric (Walpole and
Myers, 1993). This parameter analysis combines model sensitivity and variable uncertainty.

Results. Two types of results are presented: probability distributions for modeled air
concentrations and the Spearman Rank Correlation results. The probabilistic chemical air
concentration curves for each type of bath are presented in Figures 1 and 2.  An uncertainty chart
for each bath identifies the parameters that contribute most to model variance (Figures 3 and 4).

The parameter that contributes most to model variance for both bath types is air turnover rate in
the process area. The range and standard deviation of reported air turnover rates from the
Workplace Survey is very high.  This causes it to contribute more to model variance than the
process room volume. The variability of the room volume data is low and keeps it from even

appearing on this list, despite the model being equally sensitive to changes in volume or turnover
rate (as shown by Table 1).  The chemical concentration in the bath is also high on the
uncertainty charts because of the model's relative sensitivity to concentration and its variability.

Another important variable that appears on the sensitivity/uncertainty charts is bath temperature.
This parameter is used to correct Henry's Law Constant (Hc) for temperature by an exponential
relationship, but does not have much variability. Hc can also have a great effect on model
outcome, depending upon the variability of the data. The distributions of Hc used here may not
be entirely representative of the variation that can sometimes be encountered with this constant.
For instance, Mackay (1991) has observed that a great deal of variation occurs with Hc when
hydrophobic chemicals associate with the air-water interface and electrolytes or sorbents affect
solubility in water. These variations are very difficult to characterize in a study unless Hc is
measured under the conditions in question, which is not feasible here. Most chemical flux from
sparged baths comes from the open surface volatilization equation (CEB, 1991), and will cause it
to behave similarly to the unsparged bath equation as seen by results.

Comparison to Point Estimates. The probability distribution of formaldehyde air
concentrations calculated by Monte Carlo analysis were lower than expected from previously
calculated point estimates. The 90th percentile from the frequency distribution is 0.46 mg/m3,
compared to 1.55 mg/m3 calculated as a "high-end" point estimate (in the May, 1996, Exposure
Assessment Draft).  These concentrations are indicated  on Figure 1 for comparison purposes.
This suggests that the use of current point estimates results in a much more conservative air
concentration than the 90th percentile. The point estimates in the exposure assessment use the
10th percentile air turnover rate, which controls air concentration because of its large variability
shown in the uncertainty analysis.

A Monte Carlo distribution-based air turnover rate was  determined using point estimates for all
parameters and setting the air concentration equal to the 90th percentile probability frequency
distribution from Crystal Ball. This was done for several chemicals in sparged and unsparged
baths.  This distribution-based air turnover rate was calculated as follows (from 3.3.1 in
Exposure Assessment):
                       Y.TOT
where:
                v    Conc-VR-k

       Rv     = distribution-based air turnover rate (min"1)
       Fy,tot  = total emissions from all air transport mechanisms (mg/min)
       Vr     = room volume (m3)
       k      = dimensionless mixing factor (a default value of 1.0 was used)
       Cone  = 90th percentile workplace air concentration from Monte Carlo Analysis (mg/m3)
                determined using complete distributions for all parameters

This calculated air turnover rate was 0.0283 min"1 for formaldehyde in a sparged bath compared
to the 10th percentile air turnover rate of 0.0083 min"1. To ascertain the dependence of this
distribution-based air turnover rate on chemical and bath type (sparged or unsparged) this
calculation was repeated several times. These calculated (distribution-based) air turnover rates
                                                                                  DRAFT
                                          D-25

were:

•      0.0274 min"1 for isophorone in an unsparged bath.
•      0.0277 min"1 for methanol in a sparged bath.
•      0.0240 min'1 for fluoboric acid in an unsparged bath

The maximum difference between these estimated air turnover rates is 15 percent.  Because air
concentration estimates become more conservative as air turnover rates decrease, the value of
0.024 min"1 is recommended for estimating air concentrations for all chemicals to best
approximate 90th percentile air concentrations with the available data.

The results of this sensitivity analysis are consistent with those obtained by Fehrenbacher and
Hummel (1996).  They suggest default air turnover rates of 14 m3/min for a bounding, or
maximum, estimate of exposure with this equation. The default input value of ventilation rate
for obtaining "what-if", or average estimates is 85 mVmin (this value lies in the central portion of
the range for the parameter). An air turnover rate of 0.024 min"1 corresponds to a ventilation rate
of 26 m3/min, when combined with room volume.
IV.    CONCLUSIONS

It is evident that a few parameters are key to modeling chemical flux from PWB tanks.  These
key parameters are:

•      Air turnover rate;
•      Bath temperature;
•      Chemical concentration in bath; and
•      Henry's Law Constant (He).

The air models' sensitivity to these parameters and their uncertainty provides a means of
isolating them from less important variables. Isolating these variables allows for additional
scrutiny to be placed upon the point estimate assumptions used for them in the volatilization
models.

The air turnover rate assumption contributes most to overall model variance.  The chemical bath
concentration and bath temperature also contribute variance to the model, but are less important
than air turnover rate. This statement is fortified by the fact that relatively accurate information
is available on their distributions. HC appears to be least important of the four, but may have
more variability associated with it. The models appear to be largely indifferent to small changes
in most other parameters.

A comparison of point estimates with the 90th percentile from Monte Carlo analysis suggests
that using the 10th percentile value for air turnover rate yields a point estimate that is highly
conservative, and that an increased air turnover estimate of 0.024 min"1 would provide air
concentration results closer to the 90th percentile.

F.4    Design for the Environment Printed Wiring Board Project Performance
       Demonstration Methodology

Note: This workplan provides the general protocol for the Design for the Environment (DfE)
Printed Wiring Board (PWB) Project Performance Demonstration, which will generate
information for the PWB Cleaner Technologies Substitutes Assessment (CTSA) on the "making
holes conductive" step of the PWB manufacturing process. The workplan is based on input from
representatives of the PWB industry, industry suppliers, EPA, the University of Tennessee
Center for Clean Products and Clean Technologies, and other stakeholders of the DfE PWB
Project. There may be slight modifications to the workplan as preparations for the performance
demonstration progress.
I.
OVERVIEW
A.     Goals

The overall goal of this performance demonstration is to obtain specific information about
alternative technologies that effectively make holes conductive. Specifically, the goals are the
following: 1) to encourage PWB manufacturers to experiment with new products and
workpractices that may reduce environmental and human health risk and result in pollution
prevention; 2) to standardize existing information about commonly used technologies; and 3) to
gain information about technologies not in widespread use, emerging technologies, or
technologies that may be applicable to making holes conductive.

B.     General Performance Demonstration Plan

The general plan for the performance demonstration is to collect information about alternative
technologies at sites where the technologies are already being used.  These sites may be customer
production facilities, customer testing facilities (beta sites), or supplier testing facilities, in that
order of preference. The test vehicle will be a standardized 8-layer multilayer board that has
been used by industry to evaluate accelerated board testing methods.  Every attempt will be made
to limit the variability associated with the boards that is not due to differences in the technologies
being tested. The boards will be produced specifically for this performance demonstration.
Information will be collected from each demonstration site during the testing.

C.    Characteristics of Alternative Technologies to be Reported from Performance
       Testing

 1.     Product cost:  Cost per square foot of panel processed. This number will be based on
       information provided by product suppliers, such as purchase price, recommended bath
       life and treatment/disposal methods, and estimated chemical and equipment costs per
        square foot panel per day.  "Real world" information from PWB manufacturers, such as
        actual dumping frequencies, treatment/disposal methods, and chemical and equipment
        costs will be included. The product cost may differ for different shop  throughput
        categories.
                                                                                  DRAFT
                                           F-5

-------
 APPENDIX F
        Product constraints: Types of board shop processes with which the product is
        compatible.  This information will be submitted by the manufacturers and may also be
        identified as a result of the performance testing.

        Special storage, safety and disposal requirements: Flammability or volatility of the
        product, VOCs, TTOs, HAPS, Prop. 65 chemicals. This information will be requested
        from the manufacturers and will vary according to the chemicals comprising the products.
        Manufacturers will provide recommendations on disposal or treatment of wastes
        associated with the use of then: products. The storage and disposal costs will be a factor
        in determining the adjusted cost of the product.

        Ease of use:  Physical effort required to effectively use the product line, convenience.
        This is a subjective, qualitative measurement based on the judgment of the product user.
        Specific questions such as the following will be asked: How many hours of training are
        required to use this product?  What process parameters are needed to ensure good
        performance? What are the ranges of those parameters and is there much flexibility in the
        process steps?

        Duration of production cycle: The measured time of the "making holes conductive"
        process, number of operators. This information will be used to measure the labor costs
        associated with the use of the products. Labor costs will be based on the time required
        for making holes conductive with the specific products and at a standard worker wage.
        The product cycle has been defined as the desmear step through a flash up to 0.1 mil
        (includes desmear and flash).

        Effectiveness of technology, product quality: These characteristics will be assessed based
        on performance standard measurements such as aspect ratio plated, solder float test,
        thermal cycling, yield, and CpK (process capability).

Energy and natural resource data: This information will be used to measure energy
consumption and the variability of energy consumption for the use of different
technologies. Measurements of duty and load, for example, will be collected. The
information will also address materials use rates and how the rates vary with alternative
processes.

Exposure data:  These data will be used to characterize exposures  associated with
technologies not in widespread use. Exposure information for more commonly used
technologies will be collected in the Workplace Practices Survey,  conducted separately
from this study.

II.     PERFORMANCE DEMONSTRATION PROTOCOL

A.     Technologies to be Tested

1.     Electroless copper
2.     Carbon
3.     Graphite
4.     Palladium
5.     Non-formaldehyde electroless
6.     Conductive polymer
7.     Conductive ink

B.     Step One:  Identification of Suppliers and Test Sites/Facilities

Workgroup members will identify any additional suppliers of the above product lines and
participate actively in soliciting supplier participation in the performance demonstration. Any
supplier that wishes to participate will be eligible to submit their technology, provided that they
agree to comply with the testing protocol and submit the requested information.

Suppliers will identify sites that are using their product lines/technologies to make holes
conductive according to the priority sites listed below.

First preference for testing sites: customer production facilities
Second preference for testing sites: beta sites - customer testing facilities
Third preference for testing sites:  supplier testing facilities

Every vendor is guaranteed testing at one site; a submission of a second site will be subject to the
review of the performance demonstration workgroup. The workgroup will decide how many
submissions are feasible based on time and resource constraints.  If a supplier has more than one
substantially different product line, it may submit names of test facilities for each of the product
lines.

C.      Step Two: Test Vehicle Production and Characteristics

In order to minimize the variables associated with panel production, one manufacturer will
produce all of the panels. The time and materials to produce the panels will be donated to the
project by industry members. The manufacturer will produce enough 18" x 24" 8-layer
multilayer panels to send three panels to each test facility. The artwork and detailed
characteristics for the panels are being developed separately in IPC's electroless/electrolytic
plating subcommittee.  Detailed construction information, when available, will be attached to the
performance demonstration workplan. The panels will have the following characteristics:

Material: FR 4 Fiberglass Resin
Laminate thickness: .062 inches
Hole sizes: multiple holes of sizes .013, .018, and .036 inches
                                                                                   DRAFT
                                           F-7

-------
APPENDIX F
The boards will be manufactured at a single shop, stopping before the desmear step. Three
panels will be shipped to each test facility to be run through the making holes conductive line,
which begins with the desmear step.

D.    Step Three: Making Holes Conductive

The panels, once distributed to testing facilities, will be run through the making holes conductive
(MHC) process line in operation at the facility. The usual process operator will operate the line
in order to minimize error due to unfamiliarity with the technology. The panels will all be
processed in the same production run. In order to ensure compatibility with desmear processes,
the panels will be desmeared and run through the MHC line at the individual facilities.

Panels that are manufactured with the pattern plate process will be treated slightly differently
than panels manufactured with the panel plate process.  Panels manufactured with the pattern
plate process will first go through the MHC line. Dry film will be applied, and the panels will be
developed to remove all resist. The panels will then be flash plated up to 0.1 mil.

Panels that are panel plated will first go through the MHC line, and then be directly flash plated
up to 0.1 mil. This process was designed to ensure that resist residues don't interfere with the
through-hole plating process. (Note: the process was not meant to test the adhesion of the resist
to the panel or to test resist compatibility with different processes.)

After the holes have been flashed to 0.1 mil of electroplated copper, the individual test facilities
will ship all of the panels to a single plating facility, where the panels will be electroplated.  This
procedure will minimize variability due to variation hi electroplating techniques.

E.     Step Four: Information Collection at Demonstration Facilities

An independent observer will be present when the panels are run through MHC product lines at
demonstration facilities. The observer will record information on an Observer Data Collection
Sheet during the test. The information requested on this data collection sheet will be discussed
with the operator prior to the test.

F.     Step Five:  Electroplating and Testing of the Boards

After the panels have been completed (holes made conductive and flashed up to 0.1 mil) at the
different testing sites, they will be collected at one facility, where they will be electroplated to a
thickness of 1 mil. Once finished, the boards will be electrically tested using Interconnect Stress
Test (1ST) methodology. In addition, they will be microsectioned, and tests such as solder shock
and thermal cycling will be conducted.

1.0 Scope This test measures increases in resistance of plated-through hole barrels and inner layer connections as
holes are subjected to thermal cycling. Thermal cycling is produced by the application of a current through a
specific coupon configuration.  In this technique, a chain of plated-through copper barrels and inner layer
interconnects are resistance heated by passing DC current through the post interconnect for 3 minutes to bring the
temperature of the copper to a designated temperature (slightly above the Tg of the laminate in the sample).
Switching the current on and off creates thermal cycles between room temperature and the  designated temperature
within the sample. This thermal cycling induces cyclic fatigue strain in the plated-through  hole barrels and inner
layer interconnects and precipitates any infant mortality or latent defects.

The number of cycles achieved permits a quantitative assessment of the performance of the entire interconnect.
Correlation has been achieved between 1ST, Thermal Ovens, Liquid to Liquid Thermal Shock and Thermal Stress
(Solder Float) Testing.

Detailed information regarding the test is found in the NOTES 6.0 section.

6.0 Notes

6.1 Test Coupon.  Certain design rules must be applied to achieve thermal uniformity. Electronic design files for
coupon construction are available from the IPC office.  The coupon resistance should measure between 150
milliohrns and 1.5 ohms when measured at room temperature.  Two resistance values (voltage drops) for each
coupon are monitored independently, using a four wire measurement technique.

The test coupons are incorporated as part of each panel produced to monitor production or can be step and repeated
over a single panel and used to develop processes or process change.

6,2 Instrument Details.

6.2.1  Overview of General Steps of Procedure.

6.2.1.1 Data Entry. Identify and enter the specific test conditions.

6.2.1.2 Pre-cycling. The application of a trial DC current to each coupon, that elevates the individual coupons to a
predetermined resistance level, relative to the specific resistance (temperature) required for stress testing.
Compensations are applied by the equipment until all coupons achieve their independent resistance in 3 minutes + 3
seconds.

6.2.1.3 Stress Cycle. The conditions achieved during the pre-cycling stage are repeated continuously (both heating
and cooling) until the coupon exceeds one of the rejection criteria or the maximum numbers of cycles has been
reached.

6.2.1.4 Graphing.  Graphs are automatically generated that depict the performance of all or each coupon under
test. Test data can be inputted into various spreadsheet formats for further statistical analysis.

6.2.1.5 Failure Analysis - Optional.  Failure site is identified using a multimeter or thermographic system and
subsequently microsectioned.

6.2.2 Test Sequence. A description of the equipment sequence is as follows. The sequence described is for an
individual coupon, although all installed coupons are processed simultaneously.

6.2.2.1  The auto ranging multimeter measures and displays (on PC monitor) the ambient resistance (voltage drop)
of the coupon's inner layer interconnect circuit.

6.2.2.2  The system software calculates and displays the required "target" resistance (temperature). The available
stress testing range is from 50°C - 250°C (122°F - 422°F). The equation used to calculate the target resistance is as
follows:
Target Resistance = ([TCRI
                                X Th]+ R™)/!.!
where:
TCRI « Thermal coefficient of resistance for the Interconnect
Rm « Resistance of coupon at room temp (25C)
Th - Specified temperature to be achieved.

6.2.2.3  The system selects and displays a DC current associated to the measured ambient resistance, derived from
an internal software library.

NOTE: Additional equations/algorithms used by 1ST that establish the initial current selection for pre-cycling,
relative to the relationship of coupon interconnect resistance TCRI, coupon construction and stress test temperature
to be achieved are considered proprietary at this time.

6.2.2.4  The rejection resistance is calculated and displayed. This is adjustable from 1 - 100% increase. If 10% is
selected, 10% of the target resistance is calculated and added to the original resistance to establish the rejection
criteria.

6.2.2.5  Pre-cycling is initiated by the application of the selected current to the coupon, the computer monitors and
records the coupon's performance throughout this first cycle. If at the end of the  1st pre-cycle, the coupon achieves
the specified resistance level in 3 minutes ± 3 seconds, it will be accepted for subsequent stress testing.  If the
resistance level was not achieved in this time frame, the coupon will automatically be pre-cycled again with a
revised/compensated current.

	                   APPENDIXF

6.2.2.6 Forced air cooling is commenced after each pre-cycle to cool the coupons. (Requires 3.5 minutes)

6.2.2.7 The 1ST system software will automatically compensate for the difference between what actual resistance
was achieved and the target resistance.  The system will re-test using revised conditions until all coupons are
accepted for stress testing.

NOTE:  The equations/algorithms used by 1ST to compensate the DC current is considered proprietary at this tune.

6.2.2.8 The system automatically records and saves all information regarding conditions for subsequent stress
testing.

6.2.2.9 The stress test is initiated by re-applying the same DC current level established for each individual coupon
during the pre-cycle operation. Three minutes of heating is followed by two to three minutes of cooling. Cooling
time is a function of overall thickness and construction of the coupon.

6.2.2.10  Individual coupons are continually recycled using their customized heating and cooling conditions (before
failure initiates), until one of the rejection criteria is achieved or the maximum number of cycles is completed.

6.2.2.11  The coupon's resistance  "delta" (variance from initial calculated resistance) increases (positively) as
failure inception occurs. The rate of change in the delta is indicative of the mechanical change (failure) within the
interconnects.

6.2.2.12  When each coupon delta reaches the maximum resistance rejection criteria, 1ST stress testing is stopped.
The rejection criteria prevents thermal runaway (burnout) plus allows for early intervention for failure analysis to be
completed effectively.

6.2.2.13  The 1ST system continuously monitors the two independent circuits of each coupon, recording multiple
points of each cycle until the coupon exceeds one of the rejection criteria.  The data is compiled to create graphs of
each or all coupon's performance  throughout 1ST stress testing. The following are typical graphs generated by good
and bad coupons.

NOTE: The axis are not the same  in all three graphs.

* - data point considered outlier and thus not included in calculation of average.
A Incomplete bath replacement data submitted for non-formaldehyde copper process. Therefore, the process was
assumed to be similar to electroless copper for the purposes of bath replacement.
1 Bath  replacement frequency data for MHC product lines reported on product data sheets provided by chemical
supplier of each individual process.
2 Reported value was calculated by excluding any outlying values and then averaging remaining bath replacement
data for each bath.
3 To calculate panels per bath replacement, multiply average frequency of replacement by bath size in gallons and
divide by 5.6 ssf/panel.
To calculate racks per bath replacement, multiply average frequency of replacement by 75 gallons (average bath
size) and divide by 96.8 ssf/rack.
