英文摘要2013年10月对广东鹤山大气中挥发性有机化合物(VOCs)变化特征、臭氧生成潜势和来源进行了研究。结果表明,观测期间测得的 VOCs总平均值为26.6×10-9,表现为烷烃>苯系物>烯烃;烯烃日间值变化幅度较大,在清晨达到最大值;苯系物与一次污染物 CO 的变化趋势十分接近;烷烃的峰值出现时间较苯系物有所提前,且在短时间内迅速升高,表明观测点周边可能存在排放源;大气中各类 VOCs的臭氧生成潜势(OFP)贡献表现为苯系物>烯烃>烷烃;从物种来看,乙烯等10种物质对总 OFP的贡献占到了80.4%;观测期间测得的 OFP贡献较大的 VOCs物种主要来源于石化源、油漆溶剂和汽油挥发源。; Atmospheric VOCs was measured at Heshan in October 2013.The variation pattern,ozone formation potential and emis-sion sources were analyzed.Average concentration of total VOCs observed was 26.6 ×10 -9 ,while alkane >BTEX >alkene.Con-centration of alkene peaked at early morning with large variations during the daytime;variation patterns of BTEX and CO were quite similar;concentration of alkane peaked earlier than BTEX and rised rapidly in a very short time,which indicated the influence of nearby emission sources.Ozone formation potential calculation by the speciated VOCs appeared as BTEX>alkene>alkane.10 key VOCs species including ethylene contributed 80.5% of total OFP;VOCs contributed most of OFP were mainly came from petroche-mistry,paint solvents and gasoline vapor during observation.; 0; 4; 1-5,16
