[Atmospheric VOCs Pollution Characteristics and Health Risk Assessment of Large-scale Integrated Industrial Area and Surrounding Areas in Southwest China].

To investigate the characteristics of atmospheric volatile organic compound (VOCs) pollution and promote VOCs pollution prevention and control in industrial areas, in December 2020, VOCs samples collected using Summa Canisters at three observation sites were used to study the characteristics of VOCs pollution and source apportionment and to conduct a health risk assessment in large integrated industrial areas and surrounding urban areas in southwest China. The results showed that the mean (TVOCs) at site A and site B in an industrial area and at a third urban site were 105.25×10, 222.
