![]() ![]() Health impact assessments of different air pollution source contributions are important for finding the most effective abatement measures. It also implies that control actions on local PM emissions have a strong potential in abatement strategies. ![]() This emphasizes the importance to resolve within-city concentration gradients when assessing exposure. The major part of the premature deaths is in our assessment related to local emissions, with road traffic and residential wood combustion having the largest impact. In general, the main part of the exposure is due to LRT, while for black carbon, the local sources are equally or more important. Attributed premature mortality is calculated separately for the main local sources and the contribution from long-range transport (LRT), applying different relative risks. Exposure is calculated with high spatial resolution using atmospheric dispersion models. ![]() The aim of this study is to describe sectorial contributions to PM exposure and related premature mortality for three Swedish cities: Gothenburg, Stockholm and Umea. An important issue in health impact assessments is what metric, indicator and exposure-response function to use for different types of PM. There is convincing evidence that PM, almost regardless of source, has detrimental health effects. The most important anthropogenic sources of primary particulate matter (PM) in ambient air in Europe are exhaust and non-exhaust emissions from road traffic and combustion of solid biomass. ![]()
