Department of Hygiene,School of Public Health,Nanhua University(Henyang 421001,China) Abstract: Objective To understand the indoor air pollution condition in decorating materials markets,and to offer the corresponding preventive measures.Methods To survey 30 sale stores and detect the concentration of formaldehyde and volatility organic compounds (VOCs) in their indoor air.Results In sales stores with different decorating material,the concentration of formaldehyde and VOCs were higher than that of outdoor air (P<0.05),and the tallest values were 70 times and 20 times more than the value of outdoor air,respectively.The rates above standard of formaldehyde and VOCs in unventilated condition were higher than in ventilated condition (P<0.05),especially formalcehyde differ particularly.The rate above standard of the area below 50m2 was higher than above 50m2 (P<0.05).Conclusion The indoor air of the ornamental materials markets are badly polluted by formaldehyde and VOCs,and the degree of pollution is correlated to the ornamental material category,the area and ventilation of sale stores. Key words: decorative material;formaldehyde;volatility organic compounds (VOCs) 室内装修材料释放的甲醛、挥发性有机物(VOCs)已成为室内空气不可忽视的污染源〔1,2〕。为了解销售场所的空气污染状况,本文对30家装修材料销售店室内空气质量进行检测。结果报告如下。 1 对象与方法 11 检测对象 采用单纯随机抽样的方法随机抽取装修材料销售店30家,对30家销售店室内空气质量进行检测,检测项目为甲醛、VOCs(苯、甲苯、二甲苯等)。其中检测人造板材店20家,油漆涂料店6家,其他店包括地毯、避纸、塑料贴面、地板砖店各1家,选择建材店外空气作为对照。 12 检测方法 按照公共场所监测规范进行交叉布点和斜线布点的原则,根据销售店面积(x)决定采样点数,x<25m2时采2个点,25m2≤x<50m2时采3个点,x≥50m2时采5个点,采样高度为12~15m。检测时同时记录当日气温、湿度、气流、气压、销售面积,以国家最新颁布的“室内空气质量标准GB/T18883-2002”为参照标准。
