Abstract
This article examines the perceived risks to health from traffic-related air pollution among residents of four neighbourhoods in a borough of north London. Drawing on interview and survey data, the first part of the discussion presents views on possible health effects in general terms, and perceived effects on respondents themselves and their families. Respiratory and allergic conditions were found to feature most consistently, while increased heart morbidity was associated with greater uncertainty. The article goes on to reflect on the epistemological processes underlying these beliefs, concluding that although these lay beliefs largely parallel current scientific understanding, there is an inherent tension between epistemological loyalties that will be important for those working with environmental health risks to understand.
