Abstract
From March 2015 to February 2016,by sampling 20 hours a day,15 days each season,60 effective PM25 samples of Changsha City were collected in total.The analysis results show that the average concentration of Pb and Cd in Changsha monitoring samples were 424ng/m3 and 13244ng/m3.The average concentration of Pb in PM25 samples is far below the standard value,and the average concentration of Cd in PM25 samples is 25 times higher than the standard value.The average of Pb and Cd in winter PM25 samples were higher than those of other seasons Comparing Beijing,Shanghai,Guangzhou,Chongqing and other major cities,the average concentration of Pb in PM25 samples in Changsha is at a low level;The average annual concentration of Cd is at a higher level.关键词
