大庆地区总悬浮微粒中苯溶物及多环芳烃的测定与评价

通过对大庆地区总悬浮微粒（TSP）中主要化学组成──苯溶物、多环芳烃的测定分析得知：苯溶物占TSP的百分含量，年均值为10．31％，在空气中的平均浓度为12．5μg／m3。与北京燕山地区1983～1984年3个生活区（迎风、东风、东炼）苯溶物年平均值比较，大庆地区苯溶物含量较低。而对总悬浮微粒中多环芳烃的测定结果可明显看出各点采暖期苯并（a）芘、多环芳烃总量的浓度虽都明显高于非采暖期，但其致癌强度和浓度都比北京市、太原市及兰州市弱、低。

Determination and evaluation of benzene dissolved matter and multiring hydrocarbon in total suspended particles in the air of Daqing region

It is derived that the benzene percentage of annual Total SuspendedParticles (TSP)and its cone. in the air average 10. 31 % and 12. 5μg/m3 respectively,fromdetermining and analyzing benzene and multiring hydrocarbon,the main chemical composition of TSP in the air of Daqing region. Compared with the averaging annual values of3 living areas (Yingfeng,Dongfeng,Donglian)in Yanshan region of Beijing from 1983 to1984,the content of benzene in TSP in Daqing region is relatively lower. The determination of multiring hydrocarbon in TSP shows obviously that the cone. of benzo(a)pyreneand total multiring hydrocarbon during heating season are much higher than those during non-heating season and,however,the conc. and breeding cancer intensities in Daqingregion are lower than those in Beijing,Taiyuan and Lanzhou city.
