Abstract: Atmospheric VOCs samples were collected to investigate the concentrations, compositions, sources, and health risk of atmospheric VOCs in urban Jinan. Results showed that the total VOCs concentrations were comparable in 2010, 2011, 2015, and 2016, while the total VOCs concentration were lower in 2012, 2013, and 2014. Significant differences in the compositional characteristics were found among alkanes, olefins, and aromatics for each year. Main sources of atmospheric VOCs in urban Jinan during the period of the studied 7 years were determined to be motor vehicle exhaust, industrial emissions, paint and solvent using, and oil evaporation by principal factor analysis (PCA). Health risk assessment of atmospheric VOCs was carried out. The results showed that there was no presence of non-carcinogenic risks during the period of the studied 7 years, while lifetime cancer risks were close to the level of carcinogenic risks in some of the years. Attentions should be paid and measures should be taken.

Key words: VOCs, source analysis, health risk assessment
