||Identification of determinants of exposure: Consequences for measurement and control strategies
||May 2005, Vol.62, No.5, p.344-350. Illus. 21 ref.
||A worker's exposure to chemical, physical and biological agents in the workplace is never constant over time. Workers within groups with similar tasks and working environments are rarely uniformly exposed. Hence, assigning workers to "exposed" and "unexposed" groups or to exposure categories is often difficult. The design and interpretation of epidemiological studies and the implementation of workplace intervention programmes requires a knowledge of the reasons why exposure variability exists, how large this variability is, and which factors determine differences in exposure levels among workers. This article presents statistical techniques that have become available in recent years that allow simultaneous evaluation of the magnitude of variance components as well as determinants of this variability.
