室内装修材料对居室空气污染的探讨

The Influence of the Indoor Ornamental Materials on the Indoor Air Pollution

为探讨室内装修材料对居室空气污染状况,对地板革、壁纸、涂料三种普遍使用的装修材料进行了动态、非动态观察。结果各种装修材料都不同程度地污染居室空气,导致空气中耗氧量、甲醛、苯、甲苯、二甲苯浓度增高。随着装修后时间的延长,各种污染物浓度逐渐下降,装修地板革后1月内,装修壁纸加地板革后3月内,刷涂料后2月内为污染期。分析发现,加强通风可有效降低装修材料对室内空气的污染。

Investigation on the pollution of orna-metal materials, wallpaper and floor leatherette was carried out, and the factors affecting pollution for indoor air were explored. The reasults showed that the mean concentration of Pollutants, formaldehyde, mathylbenzene, xylene and chemical oxygen consumption except benzene in the indoor air were increased significantly within half a month, the mean concentration of all pollutants above fell until the thir-tyth day, after the room ornamented with floor leatherette. When the wallpaper and the floor leatherette had been covered, after three monthes' covering, the concentration level of pollutants, mathylbenzene, chemical oxygen consumption, except benzene, xylene, were significantly higher than that before the room covered, the su-perstandard rate'of formaldehyde increased. The mean concentration of pollutants fell until the fifth month after the room covered with wallpaper and floor leatherette. The result Pointed out that the room must be ventilated strongly during a period after the room ornamented with wallpaper and floor leatherette, so that the people's health can be insured.
