title: Limitations to the use of employee exposure data on air contaminants in epidemiologic studies.
abstract: The bias in the estimation of uptake of substances in the human body from exposure data gathered from ordinary workplace check-ups is discussed. It is concluded that most exposure is probably overrated. This means that exposure limits based on these premises will tend to be too high. To counteract this bias in the future, filed exposure data should be accompanied with information on a number of circumstances which prevailed at the sampling.
