Pollution Property of Particulates in the Air at the Traffic Crossing in Beijing Part Ⅱ: Pollution Property of Non-Hydrocarbons in the Particulates in the Air

The pollution of non-hydrocarbons at the Chongwenmen crossing was studied through the analysis of particulates in the air sampled in June 2000. The results showed that the traffic source was one of the major sources of non-hydrocarbons in the particulates. Non-hydrocarbons were mainly in the particulates of small size. The vehicle emission was the main source of non-hydrocarbons in the fine particulates. The mass concentration of non-hydrocarbons went up with the increase of the flux of vehicles in the daytime. At night the flux of vehicles was less, but the mass concentration of non-hydrocarbons was higher than that in the daytime because of the main influence of the emission of diesel vehicles. The pollution of non-hydrocarbons was the main pollution of phthalidyl and phenol compounds. The sources of phthalidyl in the particulates at the traffic crossing were also studied.
