Health risk assessment for residents exposed to airborne carcinogens in a city in Shanxi, China

摘要

Air pollution is serious in coal-based resources city, the development of coal industry led to some PAHs with strong carcinogenicity into the air. In order to study the level of residents' health exposured to airborne carcinogens, this study chose the city of Shanxi and measured the personal exposure level to BaP in 1992, 1994 and 2002. And a probabilistic incremental lifetime cancer risk (ILCR) model was used to conduct health risk assessment. According to the risk assessment results, the residents' cancer risk falls within the range from 10~(-6) to 10"2, which shows that the risk is unacceptable and appeared prior risk. And heating period was significantly higher than non-heating period, that showed the coal production is the major contribution factor to the cancer risk.
