摘　　要：VOCs play an increasingly important role in affecting air quality and threatening human health in China in recent years,where industry activities show a significant contribution to VOCs emission.In this article we report our long term study of industrial VOCs emissions of six major industries (vehicle manufacturing,printing,equipment coating,electronic manufacturing,furniture manufacturing and bio-pharming) on the aspects of emission characteristics,environmental impact and health risk assessment,and control challenge analysis with the purpose to obtain in-depth understanding of industry VOCs emissions and offer some original basements for national control and management of industry VOCs emissions.This study shows that all these industries give middle or low emission with total VOCs concentration less than 1000 mg/m3 at each exhaust pipe.Benzenes,esters,alcohols,ketones,alkanes,chloroalkanes and alkenes were detected as the major emission components and the most frequently monitored VOCs were benzenes,which varied obviously with different processes and industries.The environmental impact assessments indicate that vehicle manufacturing and benzenes should be prior controlled with the purpose to reduce air pollution.While,health risk assessments suggest that furniture manufacturing and chloroalkanes should be firstly controlled.Control analysis indicates that developing technologies with low cost and high efficiency and establishing and completing specific industry emission standards/regulations are the two key issues in VOCs emission management at present stage.
