title: Sources and control of error in industrial hygiene measurements.
abstract: Many sources of error exist in industrial hygiene measurements. Errors may be systematic or random. Eliminating or controlling systematic and random error during measurement, analysis, and data interpretation is a matter of aggressive quality control/quality assurance and appropriate statistical treatment of data. The occupational health care professional should be aware of error sources in industrial hygiene measurements and be on the lookout for flawed exposure estimates.
