D.4       FILTER ANALYSIS RESULTS

     This section presents the results of the optical microscopy, scan-
ning electron microscopy (SEM) and energy-dispersive X-ray (EDAX)
analyses of the hi-vol filter samples from the fifteen monitor locations
described in Section D.I.  Although filter samples were collected on six
days, three of the sampling days were determined to be unsuitable for de-
tailed analyses because of the frequent occurrance of calm or light and
variable winds during the 24-hour sampling period.  The three sample
days selected for hi-vol filter analysis are 16 August, 28 August and
9 September 1976.  (SEM results are also given for the Liberty Boro
monitor on 22 August 1976.)

     Tables D-16 through D-88 give the results of the particle count
analyses performed by optical microscopy.  Each table lists, for the
primary filter alone, the cover filter alone or the primary and cover
filters in combination, the filter number(s), the monitor location,
the sample day, the particulate loading on the filter(s) as determined
by the Coors Spectro-Cheraical Laboratory and the 24-hour average part-
iculate concentration.  Each table also gives the concurrent filter
particulate loading and 24-hour average particulate concentration for
the colocated monitor operator by the Pennsylvania Department of Envi-
ronmental Resources  (DER) or the Allegheny County Bureau of Air Pollu-
tion Control (BAPC).  In the optical microscopy analysis, the particu-
lates were classified according to six generic categories:  (1) flyash,
(2) iron oxide,  (3) magnetic iron oxide, (4) quartz, (5) biologicals and
(6) CaCo,..  The particle counts in the tables refer to a filter segment
with an area of 0.00968 square centimeters.  As explained in Section 3.6,
the particle counts in each generic category and size range were used
with the particle densities assigned to each generic category to calcu-
late the particulate mass on this filter segment.  Under the assumption
of uniform particulate loading on the filter, the total particulate mass
on the entire filter was obtained by multiplying the mass of the filter
                                D-39
-------
 segment by  the ratio of  the  total filter area  to the area of  the filter
 segment.  Both the calculated mass and the total measured mass deter-
 mined by the filter weight are entered at the  top right of each table.

     Tables D-89 through D-167 give the results of the SEN filter
 analyses.   The format for Tables D-89 through  D-167 is the same as
 for Tables  D-16 through D-88 except that, in the SEM analysis, the
 particles were classified according to the following three generic
 categories:  (1) spheres,(2) irregularly-shaped particles, and (3)
 agglomerates.  The particle  counts in Tables D-89 through D-167 refer
 to a filter segment with an  area of 0.02053 square centimeters.  As a
 consistency check, two separate SEM filter analyses were performed on
 the filter  from the Central  Laboratory monitor for 9 September 1976,
 the North Braddock monitor for 9 September 1976 and the Liberty Boro
 monitor for 28 August 1976.  The results of both analyses are included
 in the tables  (for example,  see Tables D-148 and D-149).

     The results of both the optical microscopy and SEM analyses were
 used to estimate the distributions of mass by  particle diameter.  For
 each filter and for each particle size category, the combined mass of
 particles in the six (optical microscopy) or three (SEM) generic par-
 ticle categories was calculated using the procedures outlined in
 Section 3.6.  These results were then combined to form the cumulative
 mass distributions by particle diameter shown  in Figures D-6  through
 D-ll.  (The contributions of biological particles are removed from the
 optical microscopy results in Figures D-6 through D-8.)  Each figure
 contains fifteen cumulative mass distributions, corresponding to the
 fifteen ^articulate monitoring sites.  The mass distributions in each
 figure are  identified by the monitor site number given in Table D-l.

     On the basis of the hourly wind speeds and wind directions for
the  sampling days  as  well as  the  monitor  locations,  the  filters were
 assigned to one of three categories:  (1) industrial, (2) urban, or
                                D- 40
-------
(3) rural.  The industrial filters were Baden,  Midland,  Hazelwood and
Clairton on 16 August 1976 and Baden,  Midland,  North Braddock and Liberty
Boro on both 28 August and 9 September 1976.   The Downtown and Central
Laboratory filters were placed in the  urban classification on all three
sampling days.  Similarly, the Brighton Township, Elco,  Greater Pittsburgh
Airport and South Fayette filters were placed in the rural classification
on all three sampling days.

     Figure D-12 shows the cumulative  mass distribution by particle diameter
for all of the filters analyzed by optical microscopy which have a calculated
filter loading greater than or equal to 100 milligrams.   The industrial,
urban and rural cumulative mass distributions derived from these filters
are plotted respectively in Figures D-13,  D-14  and D-15.  Similarly,
Figure D-15 shows the cumulative mass  distribution by particle diameter
for all of the filters analyzed by SEM techniques which have a calculated
filter loading greater than or equal to 100 milligrams.   The corresponding
industrial, urban and rural cumulative mass distributions are plotted
respectively in Figures D-17, D-18 and D-19.

     Energy-dispersive X-ray (EDAX) analyses were performed on a number of
filters.  The surface of each SEM filter stub analyzed by EDAX scan was
made of the entire surface.  The height of each integral energy peak record-
ed during the EDAX scan was divided by the height of the integral energy
peak of gold to obtain a ratio which was essentially free of the effects
of any discrepancies between filters in counting rates,  beam intensities,
etc.  With the exception of copper, mercury,  arsenic and lead, the thres-
hold energy ratio for elements present in larger than trace quantities
was arbitrarily set at 0.10, and the elements were ranked according to
descending magnitude of the energy ratio.   The  threshold ratio for the
trace elements of copper, mercury, arsenic and  lead was set equal to 0.03.
The results of the EDAX analyses for 16 August, 18 August and 9 September
1976 are given respectively in Tables  D-168,  D-169 and D-170.  Elements
with an energy peak much larger than the normal peaks are underlined in the
tables.
                                  D-41
-------
     For a selected subset of the filters, an SEM-EDAX analysis was
perfomed for twelve to twenty particles on each filter.   Tables D-171
through D-216 summarize the results of these analyses.  For each particle,
the elements which comprise the particle are listed in descending order
of the ratio of the integral energy peak of the element  to the integral
energy peak of gold.  Elements with energy peaks much larger than the
usual peaks, are underlined in the tables.  Tables D-171 through D-216
also give, for each particle, the particle diameter in microns (micro-
meters), the particle description (spherical, irregularly-shaped or
agglomerate) and a tentative identification of the particle type or
origin.  We point out that all of the particles considered in Tables
D-171 through D-216 had diameters larger than 5 micrometers.  SEM
photographs of some of the selected filters are shown in Figures D-20
through D-30.

     A number of large particles with diameters greater  than 40 micro-
meters observed on the filters were analyzed using the SEM-EDAX tech-
niques described above.  The results of these analyses of selected large
particles are presented in Tables D-217 through D-224, and photomicro-
graphs containing these particles are shown in Figures D-31 through D-86.
Five very large particles with diameters greater than 100 micrometers
were also analyzed.  The elemental analysis of these particles is pre-
sented in Table D-225, the descriptions and possible identifications
are given in Table D-226, and photomicrographs are shown in Figures
D-87 through D-91.

     Slag produced by the steel industry is found throughout southwest
Pennsylvania in slag dumps and has been extensively used in road and
building construction.  Therefore, slag particles are likely to be a
primary constituent  of non-traditional fugitive emissions.  We there-
fore performed an analysis of samples of the different types of slag
found in the area to determine the correlation between the elemental
compositions of these slag samples and the compositions  of some of the
particles found on the hi-vol filters.
                                D-42
-------
     Tables D-227 through D-229 give the results of the elemental analyses
of the slag samples.  The particles from the samples were divided into
two groups, one containing large particles (diameters of the order of
100 micrometers) and one containing small particles (diameters of the
order of 10 micrometers).  Table D-227A gives the results of the analysis
of large particles contained in slag samples from an electric arc fur-
nace and Table D-227B gives the results of the analysis of some of the
small particles found on the surface of these large slag particles
Photomicrographs of these samples are shown in Figures D-92 through D-101.
Similarly, Table D-227C gives the results of the analysis of the small
particulates contained in slag samples from an electric arc furance and
Table D-227D gives the results of the analysis of some of the smaller
particles found on the surface of these small slag particles.  Photomicro-
graphs of these samples are shown in Figures D-102 through D-112.  The
analyses of large particles from a blast furnace and the small particles
found on their surfaces are summarized in Tables D-228A and D-229B.
The photomicrographs of these particles are shown in Figures D-113 and
D-114.  The elemental analyses of large slag particles from a basic
oxygen furnace and the smaller particles found on their surfaces are
summarized in Tables D-229A and D-229B.  Figures D-115 and D-116 show
the corresponding photomicrographs.

     Walter C. McCrone Associates, Inc. used optical microscopy to
analyze six selected filters as a check on the validity of the SEM and
Coors optical microscopy analyses.  Tables D-230 through D-236 summarize
the results of the McCrone analyses.  These tables give the percent by
number of particles within various size ranges for three general particle
categories: (1) combustion products, (2) minerals, and (3) biological
materials.
