| In consideration of the screening method for priority control organic pollutants and monitoring data of Shijiazhuang s air quality, a principle for screening volatile organic compounds (VOCs) was developed. 20 compounds, including 7 halohydrocarbons, 5 aromatic hydrocarbons, 3 esters, 2 ketones, 1 alkene, 1 aldehyde and 1 sulfide, were screened out from the VOCs with high detection and contribution rates, and high risks to health. The pharmaceutical industries who use these VOCs might be the major sources. |
