Mixed uncertainty analysis of polycyclic aromatic hydrocarbon inhalation and risk assessment in ambient air of Beijing

摘要: This article presents the application of an integrated meth od that estimates dispersion polycyclic aromatic hydrocarbons (PAHs) in air, and assesses human health risk associated with PAHs inhalation. An uncertainty analysis method consisting three components were applied this study, where include a bootstrapping for analyzing whole process uncertainty, inhalation rate (IR) represent ation evaluating total PAH health, normally distributed absorption fraction (AF) ranging from 0% to 100% capability body. Using method, was employed assess residents Beijing, China, i nhaling air. The results indicate ambient air Beijing is important contributor impairment, although over 68% seem be safe daily carcinogenic In general, accumulated inhalati on amount relatively higher male children at 10 years old age than female 6 old. 1997, about 1.73% cancer sufferers more or less related At 95% confidence interval, approximately 272‐ 309 individual incidences can attributed pollution probability greater 500 occurrence 15.3%. While shown factor responsible while contribution might not most signifi cant one.
