Organic carbon(OC)and elemental carbon(EC)of PM2.5 in Shanghai central uban in winter was sampled and determined.Results showed that the distribution of OC and EC concentration have no difference in central urban area.OC and EC are main components in PM2.5,and the percentage of which are 8.88% and 1.49% respectively.The ratio of OC to EC is 5.73,which indicated that there is secondary organic pollution.The correlation between OC and EC mass concentration is significant,and OC and EC mainly come… CONTINUE READING
