皖西南农村地区空气污染水平调查

Investigation on Air Pollution in Countryside of Southwest Anhui Province

目的 初步了解农村室内外空气污染水平。方法 1999年 1～ 4月在安徽省西南部农村地区随机抽取 32 4户农村居民家庭 ,对室内外空气中 PM1 0 与 SO2 的污染水平进行监测调查 ,同时对家庭使用燃料情况等进行问卷调查。结果 室内外空气中 PM1 0 平均浓度高于 15 0 mg/ m3;但是 SO2 室内外平均污染水平低于 15 0 mg/ m3。PM1 0 和 SO2 的污染水平没有显著性相关关系。结论 被调查农村地区冬季存在比较严重的空气颗粒物污染 。

Objective To explore the air pollution in indoor air and outdoor air of countryside Methods The concentrations of PM 10 and SO 2 in indoor air and outdoor air of 324 families randomly selected in coutryside of southwest Anhui province were mornitored during the period from January to April in 1999,and the use of fuel for cooking and heating was investigated by questionnaire in every selected family Results The average concentrations were more than 150 mg/m 3 for PM 10 and less than 150 mg/m 3 for SO 2 in indoor air and outdoor air.There was no significant correlation between the concentrations of PM 10 and SO 2 Conclusion There existed heavier air pollution by air particulate pollutants,which caused by the burning of firewood for cooking and heatining the observed countryside area in winter
