作者历时7年,对成都市大气污染物监测、大气污染对人群健康的影响和居民死因分析及肺癌影响因素等进行了研究。其结果如下。 1.大气污染状况 选有代表性的居住区、工业区、商业区及对照的郊区,作为固定监测点,指标为大气中总悬浮颗粒物(TSP)、本并(a)芘(BaP)、二氧化硫(SO_2)和氮氧物(NOx)。TSP日平均浓度,城区(0.07～1.55mg/m~3)为郊区(0.02～0.56mg/m~3)的2.9倍,超标率分别达94.7％和58％;SO_2日平均浓度,城区(0.02～0.97mg/m~3)为郊区(0.01～0.06mg/m~3)的6.5倍,城区超标率69.1％,郊区
The author lasted for seven years and studied on the monitoring of air pollutants in Chengdu, the impact of air pollution on people’s health, the cause of death of residents and the influencing factors of lung cancer. The result is as follows. 1. Air Pollution The representative residential, industrial, commercial and suburban areas are selected as fixed monitoring points. The indicators are TSP, BaP, (SO 2) and nitrogen oxides (NOx). The daily average concentration of TSP was 2.9 times higher than that in the suburbs (0.02-0.56mg / m ~ 3) in urban areas (0.07-1.55mg / m ~ 3) ~ 0.97mg / m ~ 3) is 6.5 times of the suburbs (0.01 ~ 0.06mg / m ~ 3), the urban area exceeded the standard rate of 69.1%
