| 摘 要： | 目的 了解冬季居室空气中主要挥发性有机物(VOCs)和二氧化氮的污染水平及其影响因素.方法 于2009年1月对辽宁省大连市某小区随机选择装修后不同时期的99户居室,测定卧室、厨房及室外空气中主要挥发性有机物和二氧化氮浓度,同时对居民基本情况进行问卷调查.结果 卧室空气中甲醛、苯、甲苯和二甲苯的浓度分别为37.3,6.8,15.5和9.0μg/m3,厨房分别为39.8,12.7,18.8和9.8μg/m3,卧室和厨房空气中甲醛、苯、甲苯和二甲苯的浓度均高于室外浓度(P＜0.05)；装修时间在1年内的卧室和厨房空气中3种苯类有机化合物的浓度均明显高于装修时间≥1年的卧室和厨房空气浓度；摆放绿色植物的居室中甲醛和二氧化氮浓度明显低于未摆放绿色植物的居室(P＜0.05).结论 冬季装修居室内存在主要VOCs污染,其浓度随装修后时间的增加而降低,尤其3种苯类有机化合物的浓度下降较快.室内绿色植物对室内污染物有一定的吸附和消除作用. |
