RT Report T1 Health Effects of Interactions between Tobacco Use and Exposure to Other Agents - Environmental Health Criteria 211 A1 United Nations Environment Programme, K1 smoking K1 tobacco K1 air pollution K1 risk K1 health SN 92 4 157211 6 YR 1999 FD 1999 LK https://wedocs.unep.org/handle/20.500.11822/29485 UL https://wedocs.unep.org/handle/20.500.11822/29485 NO Tobacco use, particularly smoking, causes a range of adverse health effects, is directly implicated in a number of serious diseases, and can increase adverse effects of other chemical, physical and biological agents. Chemicals and other agents in workplaces can cause, if not controlled, disease, incapacity and early death. In the workplace it is clear that adverse effects can be produced by the synergistic interaction of tobacco smoking and other hazards. The majority of interactions of harmful tobacco smoke constituents with toxic chemicals occur when the latter are airborne, although interactions of smoking with ingested and/or absorbed harmful agents have also been reported.
