Abstract
This report presents the results of commercial laboratories participat-
ing in the second round of the bulk sample analysis quality assurance program
sponsored by the U.S. Environmental Protection Agency Asbestos-in-Schools
Program. Seventy-six laboratories which accept bulk samples for determina-
tion of asbestos content by polarized light microscopy participated in the
second round.
Laboratories received bulk samples of two asbestiform minerals (amosite,
crocidolite) and two nonasbestiform materials (cellulose, wollastonite).
Three aspects of the analytical results are considered: classification of a
sample as either asbestos (positive) or nonasbestos (negative); identifica-
tion of the specific type of asbestos or nonasbestos material present; and
quantisation of the relative amount of the major constituent present. A
performance rating was made for each laboratory, based only on the ability
to correctly classify samples. Reductions of the all-correct (4/4) score
were made only for the reporting of false positives and false negatives.
The distribution of performance ratings is: 4/4, 46 laboratories; 3/4, 25
laboratories; 2/4, 5 laboratories. The majority of classification errors
were false positives on the wollastonite sample.
Continuation of the program with future sample sets is anticipated.
Any commercial or noncommercial laboratories with capability for polarized
light microscope analysis of bulk samples may participate. Results of
commercial laboratories are made available to the EPA and to the public.
This report is submitted in fulfillment of Midwest Research Institute
Subcontract No. 47-4900-8 by Research Triangle Institute. The work was
sponsored by the U.S. Environmental Protection Agency under Contract No. 68-
01-5915 to MRI. The report covers a period from August 1, 1980, to October 31,
1980, and work was completed March 31, 1981.

ASBESTOS-CONTAINING MATERIALS IN SCHOOL BUILDINGS:
BULK SAMPLE ANALYSIS QUALITY ASSURANCE PROGRAM
1. INTRODUCTION
The Environmental Protection Agency (EPA) Asbestos-in-Schools Program
has designated polarized light microscopy (PLM) as the method of choice for
detecting asbestos fiber in bulk insulation samples.* In January 1980, a
voluntary quality assurance (QA) program was initiated for laboratories
claiming capability in PLM analysis of bulk samples. This QA program is
part of the EPA Asbestos-in-Schools Program.
Round 1 of the program was conducted in January and February 1980 and
Round 2 was conducted in August and September 1980. Any commercial or
noncommercial laboratory with PLM analytical capabilities could participate.
The following is a report on commercial laboratories that participated in
Round 2.
The QA program is not designed for laboratory accreditation and does
not seek to certify or endorse participating laboratories. Laboratories are
notified that a rating will be made of their performance. Participating
commercial laboratories and their performance ratings are included in a
source listing that is made available to EPA regional asbestos coordinators,
to state asbestos contacts, and to the public via a toll-free number estab-
lished to provide technical information. Further information on the QA
program, participating laboratories, sampling and analysis of asbestos-
containing materials, and the EPA Asbestos-in-Schools Program is available
by contacting the author at 1-800-334-8571.
2. PROCEDURES
2.1 Reporting Form and Instructions
Instructions and a reporting form developed for laboratory use in
communicating analytical results are included as Appendix A. The form
satisfies various information needs, including identity of asbestos and

ment, EPA/OTS #C00090, March 1979.

tos Analytical Programs, EPA 560/13-80-017A, December 1980.
-------
nonasbestos fibers, analytical method(s) used, quantitation procedures used,
and quality control measures employed.
2.2 Selection and Distribution of Samples
Four bulk samples were sent to each laboratory. Two were asbestos
fiber, amosite and crocidolite, and two were nonasbestos fibrous materials,
cellulose and wollastonite, commonly found in insulations. The samples were
doublebagged, coded, and packaged with a reporting form and instructions for
analysis. Sample packages were mailed on August 1, 1980, to ninety commer-
cial laboratories requesting participation.
2.3 Reference Reports
A reference analytical report was obtained from the Bureau of Mines,
U.S. Department of the Interior, Avondale, Maryland, and is included as
Appendix B. Reference report data were the basis for comparison in deter-
mining a laboratory's performance rating and were included in reports to the
laboratories.
2.4 Reports to Laboratories
Reports were issued to individual laboratories on October 31, 1980.
Reports included the results of reference analyses, data reported by the
individual laboratory, and summary data on quantitative estimates.
Estimates provided by the laboratories of the relative amounts of
sample constituents were averaged for each sample lot. Means and standard
deviations were included in reports to the laboratories. Values reported
were not used in rating laboratory performance. The distributions of quanti-
tative estimates were recorded on histograms and included in individual
reports to allow laboratories to place themselves within the distribution.
2.5 Performance Rating
Laboratory performance was assessed on the basis of correct class ifica-
tkin of "positive" and "negative" samples. Reductions of the all-correct
(4/4) score were made only for classification errors involving the reporting
of either false positives (nonasbestos sample reported as containing asbes-
tos) or false negatives (no asbestos reported in an asbestos-containing
sample).
-------
Many laboratories were successful in classifying a sample as positive
or negative but made an error in identifying the specific type of asbestos
or nonasbestos material present. These errors will be referred to as iden-
tification errors. The criterion used for performance scoring, although
not accounting for identification errors, recognizes the basic concern of
the public—whether or not asbestos fibers are present in a submitted sample.
Performance ratings were included in laboratory reports and are listed in
Appendix C.
3. RESULTS
Seventy-six of the ninety commercial laboratories supplied with samples
reported results on or before September 15, 1980. These laboratories are
designated as participants in Round 2 and are listed in Appendix C.
A total of 304 (76 x 4) samples were analyzed. Of the 304 samples, 253
were correctly classified and identified. Reporting laboratories were in
error on 51 samples, primarily wollastonite. Incorrect analyses included
3 false negatives, 32 false positives, and 16 identification errors (Table 1).
All laboratories correctly classified the amosite sample as asbestos.
Crocidolite was correctly classified as asbestos by 73 laboratories. Three
laboratories identified the crocidolite sample as mineral wool (nonasbestos).
Crocidolite is an anisotropic fiber and can be distinguished from (isotropic)
mineral wool by observation with crossed polars. Pleochroism and sign of
elongation are also optical properties diagnostic for crocidolite.
Cellulose was correctly classified as nonasbestos by 73 laboratories.
The cellulose sample was falsely reported as chrysotile by two laboratories
and as amosite by one laboratory. Attention to morphology, extinction
characteristics, and refractive index (or dispersion staining colors) should
distinguish cellulose from asbestos fiber.
The most prevalent error occurred in the classification of the nonasbes-
tos material wollastonite. Forty-seven laboratories correctly classified
the sample. Of the twenty-nine laboratories which classified the sample as
asbestos (false positive), twenty-six identified it as an amphibole and
three identified it as chrysotile. Wollastonite can be distinguished from
chrysotile by determination of refractive indices. In Cargille liquid 1.550,
wollastonite does not show dispersion staining colors (all A. < 400 nm),
and thus should not be confused with chrysotile. Wollastonite shows good

Sample was correctly classified and identified.
Samples may be classified as asbestos-containing (positive) or as non-
asbestos (negative). Classification errors are false positives or false
negatives.

dispersion staining colors in Cargille liquid 1.620. The amphiboles incor-
rectly reported included tremolite, actinolite, and anthophyllite. These
minerals have refractive index ranges totally including the range of wollas-
tonite, and therefore cannot be distinguished from wollastonite solely on
the basis of refractive index. In addition to information gained by disper-
sion staining in Cargille liquids 1.605 and 1.620, wollastonite may be dis-
tinguished from the above amphiboles by noting the sign of elongation of
sample fibers. Because of random orientation of particles, a mounted sample
of milled wollastonite will contain some fibers with positive signs of
elongation and some fibers with negative signs of elongation. Mounted
samples of chrysotile and the asbestiform amphiboles reported contain only
fibers with positive signs of elongation.
The majority of laboratories participating in Round 2 received a per-
formance rating of 4/4. Recall that reductions of the all-correct score
(4/4) are made only for classification errors. A breakdown of identification
errors within performance ratings is shown in Table 2. Most laboratories
scoring 3/4 incorrectly classified the wollastonite sample as asbestos and
did not make any identification errors. Summing classification and identi-
fication errors, it can be seen that three laboratories were in error on 3
of 4 samples and one laboratory was incorrect on all 4 samples.
The distribution of quantitative results is presented in Table 3. This
information is supplied to laboratories to enable them to compare their
quantitative results with other participating laboratories. Quantitative
results are not presently used in determining the laboratory performance
rating.
4. PLANS
The third round of the continuing QA program is currently planned for
spring 1981 and will also involve the distribution of samples and reporting
of PLM analysis results. Any commercial or noncommercial laboratories with
PLM capabilities may participate. The list of commercial laboratories will
be updated with performance ratings and participating laboratories following
each round. Future rounds are anticipated and will include samples of
asbestiform and nonasbestiform minerals as well as samples of insulation
materials removed from schools and private buildings.

INTERIM LISTING NO. 9
OF COMMERCIAL LABORATORIES WITH POLARIZED
LIGHT MICROSCOPE CAPABILITIES FOR BULK ASBESTOS IDENTIFICATION
11/1/80
The following laboratories have participated in the EPA asbestos bulk
sample quality assurance program. Listed laboratories analyzed samples
distributed in round one and/or round two of the program. Four bulk samples
were sent to each laboratory in each round. As shown below, two samples of
each round contained asbestos fiber and two were nonasbestos fibrous material
commonly found in insulation. All analyses were performed by polarized light
microscopy (PLM).
Round One
Positive: Chrysotile, anthophyllite
Negative: Mineral wool, fiberglass
Round Two
Positive: Amosite, crocidolite
Negative: Cellulose, wollastonite
Laboratory performance was assessed on the basis of correct identifi-
cation of "positive" and "negative" samples. Reductions of the all-correct
(4/4) score were made only for the reporting of false positives (nonasbestos
sample reported as containing asbestos) or false negatives (no asbestos re-
ported in an asbestos-containing sample), and not for the misidentification
of individual asbestiform mineral species. The criterion, though lenient,
recognizes the basic concern of the public—whether or not asbestos fibers
are present in a submitted sample. Performance scores for rounds one and
two are included separately on the laboratory listing. Several laboratories
entered the program after the completion of round one and therefore do not
have a score listed in that column.
The quality assurance program is not designed for laboratory accredita-
tion and does not seek to certify or endorse participating laboratories.
This list of program participants is provided as a source list of analytical
laboratories by the EPA asbestos-in-schools program. Further information on
the quality assurance program, participating laboratories, sampling and analysis
of asbestos-containing materials, and the EPA asbestos-in-schools program is
available by contacting Gene Brantly at 1-800-334-8571.

16. ABSTRACT
The second round of the Environmental Protection Agency (EPA) voluntary quality
assurance (QA) program for commercial laboratories claiming capability in the polarize!
light microscope analysis of bulk samples for asbestos was conducted in August and
September, 1980. Seventy-six laboratories each received bulk samples of two asbesti-
form minerals and two nonasbestos materials: amosite, crocidolite, cellulose, and
wollastonite. A performance rating based on correct classification of positive
(asbestos) and negative (nonasbestos) samples was scored for and reported to partici-
pating laboratories. Among the inaccurate results reported were 3 false negatives
(crocidolite) and 32 false positives (3 cellulose, 29 wollastonite). QA program
results are made available to the laboratories, the EPA, and the public. Continu-
ation of the QA program with future sample sets is anticipated.
