T. Winberry, Jr., Norma T. Murphy, and R. M. Riggin The Compendium of Methods for the Determination of Toxic Organic Compounds In Ambient Mr was com- piled to provide current, written, peer- reviewed procedures in a stan- dardized format for determining con- centrations of toxic organic com- pounds of importance in ambient air. This Second Supplement to the Com- pendium adds 5 new methods, bring- ing the number of procedures con- tained in the Compendium to 14. A complementary document titled Technical Assistance Document (TAD) for the Determination of Toxic Organic Compounds In Ambient Air provides general guidance for ambient moni- toring of organic compounds. The sampling procedures in the Compendium Include liquid im- plngers, passivated steel canisters, and various adsorbent, cryogenic, and foam trapping technology. Ana- lytical procedures include gas and liquid chromatography with various detectors including mass spec- troscopy techniques. Many toxic or- ganic compounds can be sampled and analyzed by several techniques, often with different interferences and detection limitations. This allows flex- ibility in selecting procedures to complement the user's expertise and laboratory capability. This Project Summary was devel- oped by EPA's Atmospheric Research and Exposure Assessment Laboratory, Research Triangle Park, NC, to announce key findings of the research project that is fully documented in a separate report of the same title (see Project Report ordering information at back). Introduction Toxic air pollutants have been of con- cern for many years, primarily under Section 112 of the Clean Air Act, which establishes procedures for designating National Emission Standards for Haz- ardous Air Pollutants (NESHAP). NESHAPs are intended to provide control of source categories which emit pollu- tants that "may reasonably be anticipated to result in an increase in mortality or an increase in serious irreversible, or in- capacitating reversible, illness." Likewise, public concern for protection from exposure to toxic substances has in- tensified over the last decade. Evidence of the presence of these substances in ambient air across the United States has been increasing for some time. Although many of these substances are presently controlled through occupational, con- sumer protection, water or waste disposal regulations, control of air pollution in- volving specific toxic substances has been limited. This is due, in part, to a lack of information on ambient air levels of these substances and the uncertainty of the sampling and analysis methods for their measurement. Over the last several years, state and local air pollution control agencies have increased their efforts to measure the concentrations of toxic pollutants in am- bient air. These activities have included monitoring around abandoned hazardous waste dump sites and solid waste land ------- fills, as well as other point source and urban area monitoring. For the most part, network design, siting, sampling, and analysis procedures used were based on professional judgments rather than ad- herence to any documented, uniform pro- cedures and guidelines. The absence of standardized procedures raises serious concerns about the adequacy of the data collected for their intended use. Ensuring data adequacy is critical, since major decisions on control actions, health effects, and other significant issues could be based on the interpretation of such data. To address the need for standardized measurement procedures, EPA has es- tablished a Compendium of Methods for the Determination of Toxic Organic Com- pounds in Ambient Air. This Com- pendium contains current, peer-reviewed sampling and analytical procedures in a standardized format for analysis of selected toxic organic pollutants of primary importance in ambient air. The original Compendium (EPA 600/4-84-041, 1984) contained five methods, and a Supplement (EPA 600/4-87-006, 1986) added four more procedures. This Second Supplement adds five new meth- ods to the Compendium, bringing the total number of methods in the Compen- dium to 14, covering a variety of toxic organic air pollutants. The five new pro- cedures are applicable to pesticides (Method T010), formaldehyde (Method T011), total non-methane organic compounds (Method T012), benzo(a)py- rene and other polynuclear aromatic hydrocarbons (PAHs) (Method T013), and various toxic volatile organic compounds (VOCs) (Method T014). General guidance regarding monitoring of ambient organic compounds is contained in a companion document titled Technical Assistance Document (TAD) for ff»e Determination of Toxic Organic Compounds in Ambient Air. Structure of the Compendium Each procedure of the Compendium is written to be used independently from the others. In general, the procedures are divided into the following twelve sections: • Scope • Applicable Documents • Summary of Method • Significance • Definitions • Interferences • Apparatus • Reagents/Materials • Assembly/Calibration • Sampling • Analysis • Performance Criteria and Quality Assurance The procedures are written in a stan- dardized format used by the American Society for Testing and Materials (ASTM). Each procedure has been identi- fied with a revision number and date to allow future modifications. Additional pro- cedures, which may be compound- specific or of multiple analyte design, will be added to the compendium as they be- come available. Nearly all the procedures have siderable flexibility and assume th< analyst has substantial expertise. C quently, users are responsible for paring certain standard operating p dures (SOPs) to be employed in particular laboratory. Each procedu dicates those operations for which are required. The Second Supplement contain! new methods to be added to the pendium and an update/correctic Method T09 (published in the first plement). It also contains instruction: updated pages for merging the Second Supplement information wit previously published material, an eludes a revised Table of Content: updated Tables 1 and 2 to include the previous methods and the new t ods. When so combined, the use have a fully integrated Compendium ering all 14 methods. Updated Tal gives a brief description of each m< and the types of compounds to whicl applicable.
