摘要: Although there is evidence that ultrafine particles (UFP) do affect human health are currently no legal ambient standards. The main reasons the absence of spatially resolved exposure data to investigate long-term effects and challenge defining representative reference sites for monitoring given high dependence UFP on proximity sources. objectives this study were evaluate spatial distribution in four areas Swiss Study Air Pollution Lung Heart Diseases Adults (SAPALDIA) representativeness routine air stations residential these areas. Repeated measurements during three seasons have been conducted at a total 80 area specific over median duration 7 days. Arithmetic mean PNC scattered around 10,800 particles/cm3 (interquartile range [IQR] = 7800 particles/cm3). Spatial within contrasts (90th/10th percen...
