HEALTH EFFECTS OF EXPOSURE TO MIXTURES OF AIR POLLUTANTS

The report examines published information and measurements from monitoring networks on the composition, properties and responses to the types of mixtures found in the United Kingdom, with the emphasis on urban areas. The effects of exposure to episodes in which the concentration of more than one pollutant was raised above background levels were considered. Three common types of episode are identified: summer smog, where the main indicator pollutant is ozone; vehicle smog, the indicator pollutant being oxides of nitrogen; winter smog, the indicator pollutant being sulphur dioxide, with contributions from oxides of nitrogen. Difficulties were found in predicting the effects of exposure to combinations of pollutants; a main concern was the question of whether the biological effects of mixtures of pollutants differ from those of individual pollutants in isolation. Results from chamber studies are discussed and biochemical and cellular effects are considered. Recommendations are given on the form and extent of the advice that should be given to the general public during episodes and recommendations made on the need for further research.
