     On November 10, 1977 the EPA announced its intention to study the
crushed stone industry to determine the extent of quarrying operations in
serpentinite rock deposits, the asbestos content of the rock produced, and
the exposure of the public to any emissions from usage of these rocks.
     The EPA requested state geologists to then identify rock quarries
operating in serpentinite deposits.  State geologists, on the basis of
inspection and/or reports, indicated the presence of chrysotile at eight
quarries and the possibility of chrysotile being present at several other
quarries.  The EPA directed the eight quarries where chrysotile was definitely
present to collect and ship samples to IIT Research Institute (IITRI)  on a
weekly basis for electron microscopy analysis of the rocks' asbestos content.
The EPA directed quarries, where the presence of chrysotile was possible, to
submit samples to Geological Resources, Incorporated for petrographic  analysis
for chrysotile.  The presence of chrysotile was detected petrographically in
samples from the Cardinal Stone Company quarry.  The weekly samples had been
split, and the unused halves of the samples were shipped as a single lot of
samples to IITRI for electron microscopy.   Two of the quarries originally
directed to ship samples to IITRI did not participate in the program;  thus,
the addition of this sample set brought the number of quarries analyzed to
seven.

                                  SECTION  1
                                INTRODUCTION

     The United States Environmental Protection Agency (USEPA) has undertaken
an investigation into the concentration, releasability, and emissions of
asbestos from the preparation and use of rock quarry products.1  The program
described in the following report is one part of that effort.   The USEPA
initially selected eight quarries for electron microscopy analysis.  Additional
quarries, located in areas where the geology and mineralogy indicated a reason-
able possibility that chrysotile could be present, were selected for petro-
graphic analysis.2  Each quarry sampled the IV' nominal top size crusher run
using a random sampling technique.  A sample of not less than  85 kg was
obtained weekly and was split using the ASTM C-702-71T.  Six of the eight
quarries initially selected shipped the resulting 9 kg sample  directly to
IITRI for electron microscopy analysis.  After the presence of chrysotile had
been indicated by petrographic analysis, Geological Resources, Inc. shipped a
seventh set to IITRI.
     After subdividing, drying, and sieving, samples were prepared for
analysis using electron microscope (EM) procedures developed for ambient air
measurements.   The EM procedures used identify fibers using morphology and
qualitative selected area diffraction patterns as primary criteria.  Non-
dispersive x-ray spectra are also used as needed to aid in fiber identification
No data on the non-fibrous particulates are obtained using this technique.

                                   SECTION 2
                                  CONCLUSIONS

     The first quarry, operated by Ghilotti  Brothers, Inc., consistently
shows 0.1-1.4% chrysotile content in the powder.   The two tumbled samples
(030501 and 040201) show that the chrysotile is releasable from the surface
of the larger rocks.  The amphibole counts are of low statistical significance,
ranging from 0 to 2.3%.
     The samples from the quarry operated by Rockville Crushed Stone, Inc.
are consistent for chrysotile with concentrations from 0.03 to 0.43%.  The
tumbled samples contain lower concentrations of asbestos.  The amphibole
counts show variation from 0 to 0.48%, although the counts are statistically
valid in several of the samples.  This indicates some natural variation
within the quarry.
     The samples sent by the Cardinal Stone Co. show consistent chrysotile
concentration from 0.02 to 0.30% and amphibole concentration from 0 to 1.6%.
In one sample, onevery large, nearly prismatic (Aspect Ratio 3.8:1) fiber
was found, resulting in a concentration of 52% amphibole.  This value for
amphibole mass is statistically anomalous and should not be used without
caution.
     The samples from Raisch Products' Azevedo Quarry shows variability in
chrysotile content.  The concentration is 0.5-1.6%.  The amphibole concen-
tration appears to be very low, from the detection limit to 0.25%.
     Chrysotile fibers are present in the rocks from Hillsdale Rock Co.  The
percentage of chrysotile varied from 0.2-2.7%.  The amphibole concentration
is low, ranging from below the detection limit to 0.03%.
     The samples from the D.M. Stoltzfus & Son's Cedar Hill Plant are very
similar to the Hillsdale Quarry samples.  The chrysotile concentration was

-------
0.3-2.4%.  Amphiboles were present in some samples, ranging from 0 to 0.5%.
     The samples from the Arundel Corporation's Delight Plant contained from
0.03-2.4% chrysotile.  The amphibole concentrations measured varied from 0 to
2.3% in this sample set.

                                  PROCEDURES

SAMPLE LOG-IN AND CODING
     The samples analyzed on this program were taken by each of the quarries
at the request of the U.S. Environmental  Protection Agency.  Six of the sample
sets were shipped directly to the IIT Research Institute (IITRI) on a weekly
basis.  The seventh sample set (from the  Cardinal  Stone Company) was shipped
as a single lot.  The samples were half of each weekly sample (split using an
ASTM C-702-71T procedure) originally sent to Geological Resources, Inc.  The
samples for alternate weeks were assigned a common code, but were designated
A or B, since these samples were composited after the moisture determination
when the code number identified the  composite sample.  Samples prepared by a
second technique were coded as they  were  prepared.  All codes were based on
the IITRI project number, the logbook sequence number, the logbook page number,
and the sample sequence number on the page.  All analysis of the samples was
done using only code numbers for identification.  The analyst(s) had no
knowledge as to the origin or identity of the samples run.
SAMPLE PREPARATION
     In the paragraphs below, the treatment of quarry rock samples from log-in
to submission for specimen preparation are described.  The procedures used
were, sequentially:
          •  Splitting of As-Received Samples
          •  Drying' of Aliquot

          •  Sieving of Dried Composite

Splitting and Drying of Aliquot
     Tne samples as received were split using a mechanical chute riffler in
accordance with ASTM C-702-71T.  Samples  of approximately 5 kg were obtained
                                       4

-------
using the chute riffler.  These samples were dried to constant weight at
105° ± 5°C in aluminum pans.  After obtaining a constant weight, the A and B
portions of each code number were combined to form a composite.
Sieving of Dried Composite Sampling
     The composites were each graded by size on a h" U.S. Standard Sieve using
a Gilson Soil Test shaker.  The sieving operation separated the -h" rocks from
the larger rocks, and the vigorous shaking action mixed the composited sample.
     The -%" mesh fraction was split using a mechanical chute riffler.
A 0.5 kg aliquot of the -%" mesh fraction was then sieved on an 8" diameter,
140 mesh U.S. Standard Sieve.  A 2-3 g aliquot of the fines was obtained for
preparation of the electron microscopy samples using a rotary riffler.
Tumbling of +%" Mesh Rock Chips
     An experimental procedure was designed by the EPA to measure the
"releasability" of fibers by abrasion.  In this experiment, rocks were brought
into contact with each other by tumbling in a jar.  For each quarry partici-
pating, two 0.5 kg aliquots of +h" mesh rocks were obtained by mechanical
chute riffling.  The first aliquot represented the first two weeks, and the
second aliquot the fifth and sixth weeks of the sampling program.  Each 0.5 kg
aliquot was assigned a code number and a sample obtained for EM analysis as
described below.
     The 0.5 kg aliquot was placed in a freshly cleaned and dried ceramic ball
mill jar  (size 00).  It was autogenously milled for one hour.  The material
was removed from the mill onto a No. 10 U.S. Standard Sieve, the sieve shaken
for a few minutes, and the fine powder obtained was submitted for electron
microscopy analysis under the code number assigned to the +%" mesh fraction.
The untreated rocks were stored and the milled portion of the rocks discarded.
ELECTRON MICROSCOPY SAMPLE PREPARATION PROCEDURE
     The basic procedures used to analyze the samples are documented in
Electron Microscopy Measurement of Airborne Asbestos Concentrations:  A Provi-
sional Methodology Manual.1  Prior to the sample procedures described in the
 1 EPA-600/2-77-178.  Available from USEPA, ORD Tech. Info. Staff, Cincinnati,
   Ohio 45268, Samudra, A., et al.

-------
manual, further size reduction was performed on each  sample.
     A small sample (^5 mg)  of the powder was placed  in  an  agate  mortar.   A
0.1 ml aliquot of amyl  acetate was mixed with the sample, and  the sample  was
ground with an agate pestle  until  the amyl  acetate had evaporated and the
sample appeared dry.  The powder was  recovered by quantitative rinsing (with
a 50-50 prefiltered water-alcohol  mixture)  of both the pestle  and mortar. The
sample was dispersed by treatment in  an ultrasonic bath  for 10 minutes.   The
sample was then diluted to a standard volume, and an  aliquot of the sample was
deposited on a 0.1 ym pore size Nuclepore ®  membrane filter. A 3.0 ym  pore
size Millipore®  cellulose  ester membrane  was used as a back-up  filter to aid
in obtaining uniform dispersion of the powder across  the area  filtered.
     During the course of the project it was found helpful, for both the
preparation and analysis, to allow a  1 minute sedimentation period immediately
prior to removal of the aliquot.  This allowed the large (>40  ym  diameter)
particles to settle below the sampling zone, which facilitated both dissolu-
tion of the Nuclepore® membrane and the obscuration of grid  openings by the
large particles.  Since fibers tend to settle by diameter,  and asbestiform
minerals have small diameters, IITRI  believes that no significant loss of
respirable fibers  results from this step.
     The membrane onto which the sample is  deposited  was air-dried overnight
in a Class 100 clean workbench; a wedge-shaped portion of the  filter was  cut,
carbon-coated, and a 0.3 mm  diameter  circle was then  removed with a punch
from the wedge for transfer  to a 200  mesh copper transmission  electron micro-
scopy grid.  The Jaffe washer technique was used to transfer the  sample to
the grid.
     In the Jaffe washer technique, a stack of 40 clean, 5.5 cm diameter,
paper filters is placed in a clean glass petri dish.  Spectroscopic grade
chloroform is then added until the level  is at the top of the  stack of filter
paper.  Several small  (but larger than the  0.3 mm diameter  grid)  pieces of
60 or 100  mesh stainless steel (SS)  screen are placed on the  stack of filter
paper.  An orientation mark  is placed on the outside  of  the petri dish, and
a "map" showing the location of each  piece  of SS mesh is drawn.  A sample to
be transferred is  placed, carbon-coated side down, onto  a transmission elec-
                                     6

-------
tron microscope grid and the pair is placed on the center of a  piece of SS
mesh.  The sample identification is noted on the "map".   The procedure is
repeated until the washer is filled or all  samples to be prepared  are in place.
     The chloroform level is maintained at the top surface of the  stack of
filter paper for the 24-72 hours required to dissolve the Nuclepore^  membrane.
The preparation is completed by allowing the residual  chloroform to  evaporate
from the grid, then placing the grid in a labeled grid storage  box.   All of
the procedures described are performed in a Class 100 clean workbench.
ELECTRON MICROSCOPY ANALYSIS PROCEDURES
     The prepared samples are examined using a JEOL 100C analytical  electron
microscope.  The electron microscope (EM) is used in the transmission mode to
screen the sample prior to the analysis and to perform the enumeration  and
sizing of each fiber located in the selected grid opening(s).   The scanning
transmission electron microscope (STEM) mode is used to  obtain  non-dispersive
x-ray data at a tilt angle of 40°.
     Prior to analysis of the sample, it is inspected at low (500X)  magnifica-
tion to assure that the majority (80 percent or more)  of the grid  openings are
clear and the carbon film intact.  The particle loading  is also determined at
this time.  Any sample found overloaded, damaged, or not adequately  cleared is
not used in the analytical process, but is reprepared from either  the original
suspension or the filter, as appropriate.
     The accepted preparations are  immediately counted by randomly selecting
a grid opening(s) and counting, sizing and classifying each fiber  found in the
grid opening.  The fibers are classified as:
          •  chrysotile asbestos
          •  amp^ibole asbestos
          •  not asbestos
          •  ambiguous
          •  no pattern
based on morphology and the selected area diffraction (SAED) pattern.  The
SAED patterns are not recorded (except a few for documentation) or indexed.
The comparison is visual and if the pattern is obviously compatible  with one
of the asbestos minerals, the fiber is so classified.   When a fiber  is  on

-------
the borderline, a non-dispersive x-ray pattern  is often used as an aid  in the
classification.
     Similarly, fibers whose SAED pattern  characteristics differ significantly
from asbestos pattern characteristics  are  classified as "not asbestos", and
those providing no pattern1  or indeterminate  patterns are classified as "no
pattern" or "ambiguous" fibers, respectively.   This data, together with the
size data taken for each fiber, is reported for each fiber observed.
     The fiber enumeration and sizing  is continued until approximately  100
fibers have been measured or 10 grid openings  have been examined.
     The measured sizes of each fiber  classified as chrysotile or amphibole
are used to estimate the mass of the fiber.   The mass of the fiber is estimated
using the following equation which assumes a  cylindrical shape.
                             Mf
          where:
                     Mf  =  estimated mass of the fiber,  fg
                      £  =  length,  mmt
                      w  =  width, mmt
                      p  =  density,  2600  -% for chrysotile,  3000-^-

                                   RESULTS

     The results of the program are the analyses of the samples and the
supporting data.  The analyses are summarized in Tables 1-3, where data on the
quantity of powder deposited, the area analyzed and the fiber counts are given
by chrysotile, amphibole and "others".  Also provided is the estimated number
of fibers on the filter, the estimated mass on the filter and the weight % for
each of the chrysotile and amphibole fiber types in each sample.

               WT: h     iu  Mass  of  Sample  on  Filter  (10-6g)

     The ratio between the number of fibers counted and the total number on
the filter is the ratio of the area counted to the filter area, 9.6 cm2; e.g.,
for Sample 010401, Table 1, line 1:
                               9.6  cm2
                            72 x
                                          =  in x 10
                                             1U x 1U
     Some of the variation in the weight % numbers reported will be due to
natural variation in the quarried minerals; however, some variation is intro-
duced by the analytical method.  The precision of measurement for the total
mass on the filter is ±5%.  The precision of the EPA Provisional Method is
±10% for one operator, and ±20% for two different operators, as were used
during the analyses of the crushed stone samples.  The estimated precision in
the weight % values generated is ±20%.
     The detailed data on each sample is tabulated in Appendix A, Tables A-l
to A-52.
     The data on the sieving and the powder tumbling is presented in Tables
4 to 10, where the data is organized by quarry.  Table 11 contains the record
by sample and fiber number of the electron micrographs taken during the
analyses.  Selected micrographs and/or non-dispersive x-ray spectra are
                                      9

presented in Appendix B, Figures B-l to B-52.
     In the appendix, all diameter values are rounded to the nearest 0.05 ym
on the following basis.   The diameter is visually estimated to the nearest
0.5 mm.  Since this can be either a plus or minus value, the precision is
estimated as
            1 mm
103 ym
                    mm
        16,OOOX magnification
                                                  or about 0.06 ym
The rounding is carried out after completion of all calculations.  This can
give rise to wide discrepancies in the tabulated aspect ratio and the £/d
ratio taken from the tables.
     To illustrate an extreme, one fiber having a diameter of 0.025 and
another with a diameter of 0.074 would both be tabulated as 0.05 ym diameter.
If they have the same length, the ratio of the tabulated aspect ratios would
be:
                                0.074  n   ,
                                0^25  *  3"

Thus variations of this magnitude may be present in the tables in Appendix A.

 16. ABSTRACT
        The purpose of this  study was to determine the presence and concentration
   of asbestiform minerals  in  seven (7)  rock quarries.  Generally, each of the
   participating quarries submitted samples of its product  for analysis on a weekly
   basis for approximately  twelve (12) weeks.  A representative aliquot was obtained
   from each sample and  consecutive weekly samples were composited.  Analysis of the
   samples was performed on  a  transmission electron microscope, using morphology and
   selected area electron diffraction patterns as primary criteria, with the aid of
   non-dispersive x-ray  spectra  on difficult or selected fibers.   Each fiber observed
   was categorized and sized.  The size data was used to compute mass estimates for
   chrysotile and amphibole  fibers.  The concentration of chrysotile or amphibole  was
   computed on a weight  percent  basis.  Several of the quarries were found to contain
   asbestos.
