Occupational exposure to environmental tobacco smoke and health risk assessment.

摘要: Abstract This article addresses concepts of environmental tobacco smoke (ETS) exposure assessment relevant for health risk based on human studies. We present issues that should be considered when selecting a method ETS the purposes and review data levels in workplace home environments. Two types estimates are needed quantitative effects resulting from occupational exposure: (italic)a(/italic)) an unbiased estimate exposure-effect (or dose-response) relation between effect interest, (italic)b(/italic)) distribution different workplaces. By combining estimated with information population we can calculate proportions disease cases attributable to as well excess number due specified conditions. Several dimensions profile assessing estimating relation, including magnitude biologically time specificity exposure. The is determined by source strength, factors modifying concentrations, duration Time considerations include latency period each outcome time-exposure mechanisms, sensitive age regard effects. most appropriate indicator depends these assessed methods.
