This volume addresses the problems arising from pollutants that all too commonly contaminate the indoor environment, including biological sources such as bacteria, fungi and moulds, common combustion products, radon and other sources of radiation, solvents used in industry and the home, asbestos and dust pollution. The aim is to provide a balanced account of the health risks associated with these major pollutants and to quantify the scale of the problem on a pollutant-by-pollutant basis. Each chapter covers exposure levels, sources of pollution and routes of uptake, health effects, control measures, and regulatory guidelines.
