A semicontinuous study on the ecotoxicity of atmospheric particles using a versatile aerosol concentration enrichment system (VACES): development and field characterization

Abstract. Oxidative stress can be used to evaluate not only adverse health effects but also ecological effects, limited research uses eco-toxicological assay assess the risks posed by particle matters non-human biomes. One important reason might that concentration of toxic components atmospheric particles is far below high detection limit eco-toxic measurement. To solve rapid problem, we extended a versatile aerosol enrichment system (VACES) for ecotoxicity measurement and firstly VACES provide comparison between non-concentrated concentrated aerosols in ambient air. In this study, total (number or mass), chemical were all increased approximately 7 10 times VACES, making above baseline. The data PM2.5 showed low was matched with ecotoxicity, although corresponded higher ecotoxicity. addition, saturation temperature caused loss particulate matter, which nitrate accounted about 18 %.
