| Abstract |
The second round of the Environmental Protection Agency (EPA) voluntary quality assurance (QA) program for commercial laboratories claiming capability in the polarized light microscope analysis of bulk samples for asbestos was conducted in August and September, 1980. Seventy-six laboratories each received bulk samples of two asbestiform 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 participating 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. Continuation of the QA program with future sample sets is anticipated. |
