ESTIMATION OF CONSUMER EXPOSURE TO CHEMICALS - APPLICATION OF SIMPLE-MODELS

Occupational and consumer exposure only recently has become an issue m eriting a more systematic approach. This paper offers a method for the estimation of consumer exposure on the basis of limited data sets. Fo llowing a selection of exposure route(s) of concern, acute, subchronic and chronic exposure scenarios are identified based on the expected e xposure frequency and duration. Algorithms for the estimation of the e xternal exposure are presented and illustrated by example calculations . The external and internal exposure assessment is further integrated into a hazard assessment scheme for consumer products including the de termination of no-effect levels for man and the calculation of hazard quotients.
