外文摘要：Polycyclic aromatic hydrocarbons (PAHs) in indoor dust are one of the common exposure sources for children worldwide.The aim of this study is to explore PAHs pollution status in indoor dust and estimate health risk on Chinese children with big data.Weighted average concentration was used to analyze source and characterization of PAHs in indoor dust based on peer-reviewed literature.According to specific inclusion criteria,17 studies were included finally to analyze weighted average concentration.The national average concentration of Σ16PAHs was approximately 25.696 μg/g.The highest concentration of Σ16PAHs was in Shanxi (2111.667 μg/ g),and the lowest was in Hong Kong (1.505 μg/g).The concentrations in Shanxi and Guangdong were higher than national level and the over standard rate was 18.18％.The concentrations of individual PAHs varied greatly across the country,and Flu in Shanxi was the highest (189.400 μg/ g).The sources of PAHs varied in different regions and combustion processes played a leading role.PAHs exposure through ingestion and dermal contact was more carcinogenic than inhalation.The incremental lifetime cancer risk model indicated that children lived in Shanxi were found in the highest health risk coupled with the highest BaPE concentration (54.074 μg/g).Although PAHs concentrations of indoor dust showed a downward trend from 2005 to 2018,indoor environmental sanitation should be improved with multidisciplinary efforts.Health standard should be possibly established to minimize children exposure to PAHs in indoor dust in China.
