Total and Bioaccessible Fraction of Elements in Urban Aerosol
Mikuška, Pavel ; Cigánková, Hana ; Hegrová, J.
Atmospheric aerosols have significant impact on health and environment. Elements constitute an important particulate component which have received the attention to understand their environmental and health impacts. Elements enter the human body through inhalation of aerosols causing several health issue (asthma, cardiovascular and respiratory diseases, lung cancer).\nThe potential health effects of elements in PM depend on their toxicity, concentration, and bioaccessibility. It is assumed that the bioaccessible fraction of elements is more relevant for evaluating human health risks than the total concentration of elements. The aim of this study was to determine the total and bioaccessible concentration of elements in urban PM1 and PM2.5 aerosol during four seasons.
