[Effects on health of particulate air pollution in Denmark--a quantitative assessment].

Introduction: Ambient air pollution is a risk factor for mortality and morbidity. The aim of this study was to quantify the health effects related to particulate matter (PM10) in Denmark.

Materials And Methods: We used relative risk estimates in relation to PM10 based on the epidemiological literature.

[Effects of traffic-generated ultrafine particles on health].

Epidemiological studies have consistently shown relation between exposure to particulate matter in urban air and cardiovascular and pulmonary morbidity and mortality. Some recent population studies suggest that the ultrafine fraction of particulate matter generated by motorised vehicles is particularly damaging. Animal studies and cell culture experiments support this hypothesis and address the possible mechanisms of action.
