Pollution properties of atmospheric particles in Harbin during heating and non-heating periods
|
Abstract:
In order to investigate the effect of heating on the chemical characteristics of atmospheric particles,TSP,PM10 and PM2.5 were collected before,in and after heating period.The size distribution and concentration characteristics of atmospheric particles were investigated.Simultaneously,20 metallic elements and 2 carbonaceous contents were further analyzed.The results showed that the concentrations of TSP and PM10 exceeded the national secondary standard in December,January,March and April,but met the standar...
