为了解宣威市某村燃烟煤居室内空气污染的现状,于2011年1月采集该村燃煤炉型分别为烟囱地炉和模拟火塘的村民各2户,得到室内、外空气样本各54份,对空气中总悬浮颗粒物(TSP)和苯并(a)芘(BaP)浓度进行监测。烟囱地炉居室内空气中TSP超出三级空气质量标准0.8倍,BaP超出标准值90倍;室外空气中BaP超出标准值2.5倍。模拟火塘居室内空气中TSP超出三级空气质量标准7.5倍,BaP超出标准值664倍;室外空气中TSP超出三级空气质量标准0.07倍,BaP超出标准值6倍。说明改炉灶可以降低因燃烟煤导致的空气TSP、BaP浓度,但需进一步改进。
In order to understand the current situation of indoor air pollution caused by burning bituminous coal in a village in Xuanwei City, in January 2011, two coal-burning stoves of the village, namely, a stove for a chimney and a villager for a simulated fire pond, were collected, each of which had 54 indoor and outdoor air samples The concentrations of total suspended particulates (TSP) and benzo (a) pyrene (BaP) in the air were monitored. Chimney furnace indoor air TSP exceeded three air quality standards 0.8 times, BaP exceeded 90 times the standard value; outdoor air BaP exceeded 2.5 times the standard value. Indoor fire Tiantang indoor air TSP exceeded three air quality standards 7.5 times, BaP 664 times the standard value; outdoor air TSP exceeded three air quality standards 0.07 times, BaP beyond the standard value of 6 times. This shows that changing stoves can reduce the concentration of air TSP and BaP caused by burning bituminous coal, but further improvement is needed.
