摘要
以国际上近年来通用的危险度评价方法为基础,结合大气污染物每增高一单位对儿童呼吸系统健康造成的损失,综合定量评价了沈阳市城区大气污染物对儿童呼吸系统的影响。结果表明:2004年沈阳市皇姑区采暖期大气中PM_(10)、SO_2和NOx污染造成儿童上呼吸道感染患病率分别增加0.899%、0.657%和0.536%,儿童气管炎患病率分别增加0.039%、0.047%和0.053%,儿童肺炎患病率分别增加0.069%、0.058%和0.054%。因此,沈阳市采暖期大气PM_(10)、SO_2、NOx污染对儿童呼吸系统造成了一定的影响,并导致了其相应疾病患病人数的增加。
Based on the internationally accepted quantitative risk assessment framework and the unit increase in children respiratory system morbidity per unit increase of air pollutant level, the quantitative result of impact of ambient air pollution on chilch'en respiratory system was evaluated in the urban district of Shenyang. And according the result, the air pollutant levels of PM10, SO2 and NOx during the heating period in 2004 were associated with 0. 899 %, 0. 657 % and 0.536 % increase in children upper respiratory tract infection morbidity, 0. 039 %, 0. 047% and 0. 053 % increase in children tracheitis morbidity and 0.069%, 0. 058 % and 0. 054% increase in children pneumonia morbidity. So the levels of PM10, SO2 amd NOx during the heating period in Shenyang on children respiratory system health were considerable, and they were colTelated will, the increase of children respiratory diseases numbers.
