The emission inventory anthropogenic source VOCs species in 2021 in Nanjing
Based on emission factor method,the Volatile Organic Compounds(VOCs)emission inventory of Nanjing was established in 2021 using the activity data of various VOCs emission sources,emission factors and source profiles of VOCs.VOCs emissions for each source and different VOCs source profiles in Nanjing were analyzed.The total amount of VOCs emissions in Nanjing in 2021 was about 302.85kt.Industrial process sources were the major source of total VOCs emissions accounting for 60.41%(182.94kt),followed by on-road mobile sources(19.46%).The least emission contribution was from off-road mobile sources(0.40%).The highest emission for VOCs species inventory come from alkanes(109.06kt),followed by halogenated hydrocarbon(75.08kt)and aromatic hydrocarbon emissions(50.72kt).The top ten species contributing to emissions were vinyl chloride,ethane,propane,trichloroethylene,1,2-dichloroethane,p-xylene,n-butane,ethylbenzene,other alkanes and ethylene,respectively.The emissions of top ten species accounted for 63.96%of the total emissions,which mainly from synthetic fiber monomer manufacturing and crude oil processing.
