Abstract

Benzo[α]pyrene supported on PM2.5 has strong carcinogenicity and threatens human lifespan. In this paper, by setting up sampling sites in Haidian District in Beijing, we continuously collected samples of atmospheric PM2.5 in 2016 and measured the concentration of BaP contained in the samples. In the meta-analysis of BaP epidemiology and animal toxicology data, a dose-response relationship was obtained. Then, calculating the number of newly-increased lung cancers’ cases resulting from the respiratory exposure pathway, and combined with measured concentrations of BaP, the years of lived with disability is calculated with the result was 49.14 years. Based on the demographic data of Beijing, the average life expectancy loss due to lung cancer calculated using the life table method was 1.22 years, and the calculated years of life lost due to premature death was 63.68 years. Therefore, it can be estimated that the loss of healthy life caused by BaP was 112.82 years.
