Beschreibungen/Notizen

• We studied the concentrations, seasonal distributions, sources, exposures, and health risks of phthalates in indoor and outdoor PM_(2.5) in Beijing. The results showed that phthalate concentrations during haze periods were significantly higher than during non-haze periods both indoors and outdoors, with higher concentrations for the former, which reached a maximum of 1995.56 ng m^(-3). Phthalates are mainly derived from the use of indoor plasticized products, the outdoor plastic products industry, and other sources of fuel emissions. Lifelong exposure to fine (2-ethylhexyl) phthalate (DEHP) through inhalation and dermal absorption was calculated, and the results indicated a risk of cancer, with DEHP carcinogenic risk levels of 4.09 × 10^(-6) and 10.50 × 10^(-6) for adults and children, respectively. The highest DEHP carcinogenic risk group was 1-2-year-old children, and the risk decreased afterward with age.
