江苏省13省辖市冬季室内环境污染监测分析及其对策

Monitoring Appraisal of the Environment Pollutants of Civil Construction Engineerings of the 13 Cities in Jiangsu Province in Winter and its Counterplans

文章对江苏省13省辖市525个Ⅰ类、610个Ⅱ类共1135处民用建筑工程冬季室内环境主要污染物―甲醛、苯、TVOC、氨及氡进行了取样监测分析。检测数据统计表明:全省氡、氨、苯合格率为100%;甲醛合格率为98.5%;TVOC合格率为98.3%。其中23个Ⅰ类建筑工程、14个Ⅱ类处室内空气质量有不合格项,样本总超标率为8.4%。甲醛、TVOC是冬季室内空气中的主要污染物。我省大部分民用建筑,在冬季由于室内外温差较大、建筑物的高气闭性和低换气量,使室内装饰装修材料散发的甲醛、TVOC等污染物,在室内聚集产生叠加效应,是引起室内空气污染的主要原因。文章提出:加强室内环境监测执法力度、减小人造板材装修度、提高室内通风效率、采用合适净化等措施,是解决冬季室内环境污染的有效途径。

This paper analyzes environment main pollutants in indoor of the 525 Ⅰ classification , the 610 Ⅱ classification and the total of 1135 civil construction engineerings of 13 cities in Jiangsu provinces in winter-- formaldehyde, TVOC, benzen, ammonia and radon. The results of the statisticses in Jiangsu provinces shows that the qualified rate of benzene, ammonia and radon is 100%, formaldehyde is 98.5% and TVOC is 98.3%. There are 23 Ⅰ classification and 14 Ⅱ classification civil construction engineerings in indoor contained unqualified rate of 8.4%. The formaldehyde and TVOC is main pollutants in indoor air in winter. The main reasons of the air pollutants are sealing degree higher and the low exchange in indoor air. This paper put forward to the improvement methods： strengthen the power of the enforce of law in environment pollution; reduce the dosage of decorated wood material; raise high the ventilated efficiency in indoor air and adopt the appropriate decontaminations is the valid path to lower the environment pollutions in indoor.
