【摘要】：目的探讨不同装修程度居室空气中苯的污染现状,分析其变化趋势及防控对策。方法在贵阳市住宅小区选择新装修居室,按使用各类人造板材及聚氨酯清漆的用量、外购家具装填情况等装修水平的不同分为3个实验组(每组8户),低装修水平1组,高装修水平1组,家具装填1组;设未使用人造板材、聚氨酯清漆和家具装填的1组(对照组),对上述组别中苯共作5次监测(15 d监测1次),测定方法按(GB 50325-2010)热解析-气相色谱法。结果低水平组第1次监测苯浓度范围(0.009~0.240 mg/m3),显著低于高水平组(0.078~1.040 mg/m3)和家具装填组(0.077~0.140 mg/m3);3个实验组苯浓度均高于对照组(P0.05),至第5次监测,家具装填组的苯浓度水平(0.009~0.089 mg/m3)高水平组(0.009~0.075 mg/m3)。同时,随时间的延长,各实验组苯浓度呈下降趋势。结论高装修水平组和家具装填组室内苯浓度明显高于低装修水平组,主要与人造板材、聚氨酯清漆的用量和质量、家具的装填和质量相关。
[Abstract]:Objective to explore the present situation of benzene pollution in indoor air with different decoration degrees, and analyze its changing trend and prevention and control countermeasures. Methods the newly decorated rooms were selected in Guiyang residential district. According to the amount of various artificial panels and polyurethane varnishes, the decoration level of purchased furniture was divided into three experimental groups (8 households per group and 1 group with low decoration level). High decoration level 1 group, furniture filling 1 group; not using artificial panels, One group of polyurethane varnish and furniture filling (control group, 5 times monitoring benzene in the above group was monitored once for 15 days, the method was determined by GB50325-2010). Results the first monitoring range of benzene concentration in the low level group was 0.009 ~ 0.240 mg / m ~ (3), which was significantly lower than that in the high level group (0.078 ~ 1.040 mg / m ~ (3) and furniture filling group (0.077 ~ 0.140 mg / m ~ (3). The benzene concentration in the three experimental groups was higher than that in the control group (P 0.05), and the benzene concentration in the furniture loading group was 0.009 ~ 0.089 mg / m ~ (3) (0.009 ~ 0.089 mg / m ~ (3). At the same time, benzene concentration in each experimental group decreased with time. Conclusion the indoor benzene concentration in the high decoration level group and furniture loading group was significantly higher than that in the low decoration level group, which was related to the quantity and quality of artificial panel, polyurethane varnish, furniture loading and quality.
