【摘要】：目的了解广东省中山市室内新装修家居和办公场所空气质量。方法统计分析中山市2007—2011年监测的179户、1 269个监测点的家居和办公场所监测数据,监测指标包括甲醛、苯、甲苯、二甲苯和总挥发性有机化合物(TVOCs),对其进行空气质量指数分析。结果甲醛、苯、甲苯、二甲苯和TVOCs的最高浓度分别为1.48 mg/m3、117.52 mg/m3、21.68 mg/m3、0.73 mg/m3和10.3 mg/m3;家居场所的甲醛、甲苯和二甲苯浓度合格率显著低于办公场所(χ2=83.51,P=0.000;χ2=86.15,P=0.000;χ2=64.68,P=0.000);家居场所和办公场所的室内空气质量指数平均秩次分别为844.94和570.00,办公场所的室内空气质量优于家居场所(Z=-13.799,P0.001)。结论新装修场所有机物污染程度参差不齐,甲醛是首要的室内空气污染物,家居场所是室内空气污染的高风险场所,应对重点污染物和重点场所加强预防控制。
[Abstract]:Objective to investigate the air quality of newly decorated home and office premises in Zhongshan City, Guangdong Province. Methods the monitoring data of domestic and office premises of 179 households in Zhongshan City from 2007 to 2011 were analyzed. The monitoring indexes included formaldehyde, benzene and toluene. Xylene and total volatile organic compounds (TVOCs) were analyzed by air quality index. Results the highest concentrations of formaldehyde, benzene, toluene, xylene and TVOCs were 1.48 mg/m3117.52 / m3cr / m30.73 mg/m3 and 10.3 mg / m3, respectively. The qualified rates of toluene and xylene concentrations were significantly lower than those in office premises (蠂 ~ 2 ~ (2) 83.51U ~ (0.000); 蠂 ~ (2 +) ~ (86.15) P ~ (0.000); 蠂 ~ (2 +) ~ (64.68) P ~ (0.000); the average rank of indoor air quality index of domestic and office premises were 844.94 and 570.000.The indoor air quality of office premises was better than that of domestic premises. Conclusion the degree of organic pollution in newly decorated place is not uniform, formaldehyde is the primary indoor air pollutant, and household place is the high risk place of indoor air pollution. The prevention and control of key pollutants and key places should be strengthened.
