Study On The Volatile Organic Compounds (VOCs) Characteristics In The Ambient Air Of ShiJiaZhuang City

Volatile organic compounds(VOCs)play an important role in atmospheric chemistry,is an important precursor for the formation of photochemical smog,one of the important precursors of PM2.5,some of the regional environmental problems,such as the two organic pollution and human health effects from exposure have important influence.In addition,volatile organic compounds(VOCs)can also enter the body through the respiratory system and skin health hazards,some species have been identified as carcinogenic and teratogenic.Therefore,the city of atmospheric volatile organic compounds(VOCs)concentration,composition characteristics,key active components affecting the air quality of city of scientific recognition system It has important scientific significance and effective control measures set.This paper takes Shijiazhuang City eight air automatic site as the research area,the high-tech zones,22 south campus,people's hall,Century Park,Southwest Hospital,higher education,northwest water 7 points and background points Longshan laboratory analysis data,atmospheric volatile organic compounds(TVOC)in Shijiazhuang city of the the characteristics of pollution,pollution level and spatial and temporal variation,analysis of TVOC and AQI,ozone,correlation between PM2.5 and ozone formation potential of volatile organic compounds were calculated,put forward Shijiazhuang City VOCs priority control list,and then gives the volatilization of Shijiazhuang City Countermeasures of pollution control of organic materials.Considering the detection rate,contribution rate,human health,ecological and environmental hazard sources and uses 11 kinds of material characteristics of pollutants as a priority control.As follows: acrolein,toluene,methyl methacrylate,naphthalene,benzene,xylene,hexachloro butadiene-1.3-,acetic acid 2-vinyl ester,acetone,butanone,ethylbenzene.
