Description of Multiple Exposure Situations in Québec Workplaces Taken from Occupational Exposure Databases

Abstract

Many sectors of activity are subject to concomitant exposure to a number of chemical contaminants, or multiple exposures, for which the combined effects on health could be significant.

Little information exists about the most frequent situations of multiple exposure, which agents are most often involved, and the sectors of activity or occupations concerned. In addition, there are few sources of information that would make it possible to generate this knowledge so that it could be applied across all industrial activity. In several countries, occupational exposure measurement databases compile information gathered in the scope of prevention or regulatory control activities. They represent a potential source of information on multiple exposures and have not yet been utilized in this context.

This project aims to describe multiple exposure situations in pertinent workplaces in Québec and to identify which cases could be associated with high combined risk.
