Abstract
Epidemiologic study of the asbestos (1332214) products industry to measure the exposure of workers to asbestos dust for a period of 20 years. Impinger samples were collected routinely in both the baseline surveys and resurveys for relating dust levels to the threshold limit value existing at the time of the study. The advantages and disadvantages of the various measurement methods are discussed. Methods of fiber concentration measurement are considered helpful in measuring airborne asbestos fibers which are a factor in lung cancer. The criteria for the selection of a standard method for setting a safe level of exposure are enumerated. Since the impinger method does not meet any of the criteria, weight methods are given preference. At present fiber counts on membrane filters are the best method of estimating exposure as related to the risk of asbestosis and the airborne fiber concentration as a factor in the risk of lung cancer.
