城市住宅内化学污染已成为非常严重的社会问题,为了解当前住宅内化学物污染的现状,进行了两次调查.第一次在北京和长沙各选取10户住宅,进行了室内空气中15项主要化学污染物浓度的检测,并统计得出各项指标的平均值、标准值、最小值、最大值及超标率.结果表明:目前住宅内出现最广泛、超标最严重的化学污染物为甲醛、苯及 TVOC.第二次调查选在上海,主要针对第一次调查结果进行.选择了26户家庭进行问卷和实测调查,得出影响室内化学污染的各因素中,家具和建筑装修材料污染所占比重最大.并通过绘制各污染物与装修时间关系图,得出装修后至少应通风3个月入住.

Indoor chemical pollution has become a serious social issue. So, the field surveys were proposed twice to get the information about the chemical pollution in urban residential buildings. The field experiment was carried in 20 new-decorated residential buildings in Beijing and Changsha respectively, and 15 major indoor chemical contaminants were tested. The tests indicate three kinds of substances exist -ed in all tested houses, and their concentration were relatively high. Then a second field experiment launched for the three substances in Shanghai. Questionnaire and field test were included during the second survey. The results show furniture and architectural decoration materi -als are the most important factors to indoor chemical pollution; the new-decorated residential buildings should maintain ventilation for at least three months before moving in.
