摘要
目的了解北京市丰台区公共场所空气中甲醛及TVOC的污染状况。方法于2015年-2016年对北京市丰台区辖区内住宿、购物、美容美发及家具建材4类148家公共场所进行了甲醛和TVOC监测,共采集样品589份。根据GB/T 18204.2—2014《公共场所卫生检验方法化学污染物》的要求布点采样,并按此标准要求进行实验室检测。检测结果按照公共场所相关行业标准进行判定。结果甲醛的总合格率为92.54%,浓度均值为(0.063±0.031)mg/m^3,购物场所的甲醛合格率(88.26%)比住宿场所合格率(96.69%)低(P<0.01),浓度水平较高(P<0.01),且2016年甲醛污染比2015年严重(P<0.01)。而TVOC浓度均值为(0.155±0.082)mg/m^3,家具建材城的TVOC浓度(0.379±0.088)mg/m^3则高于美容美发场所(0.088±0.039)mg/m^3(P<0.01)。结论公共场所TVOC污染监管工作仍需加强,同时应当加快TVOC等污染物卫生标准的制定。
Objective To evaluate the status of air formaldehyde and total volatile organic compound（ TVOC） in public places in Fengtai District of Beijing. Methods From 2015 to 2016,formaldehyde and TVOC in air of 148 public places including hotels,shopping mall,hair salon,and furniture markets in Fengtai District were monitored by Fengtai District Center for Disease Control and Prevention. Finally,589 air samples were collected. According to the Standard Examination Methods for Public Places Chemical Pollutants（ GB/T 18204. 2-2014）,sampling distribution was conducted,and the concentration of air formaldehydes and TVOC were examined. The detected results were all determined by the related hygienic standard of public places.Results The total qualified rates of formaldehyde was 92. 54% and the average concentration of formaldehyde was（ 0. 063 ±0. 031） mg/m^3. The qualified rate of formaldehyde in shopping mall was 88. 26%,which was significantly lower than that in hotels（ 96. 69%,P 〈0. 01）. In addition,the average concentration of formaldehyde in shopping mall was reversely higher than that in hotels（ P 〈0. 01）,and the formaldehyde pollution was more serious in 2016 than that in 2015（ P 〈0. 01）. Besides,the average concentration of TVOC in all monitored public places was（ 0. 155 ± 0. 082） mg/m^3. The average status of TVOC in furniture markets was（ 0. 379 ± 0. 088） mg/m^3,which was higher than that in hair salons（ 0. 088 ± 0. 039） mg/m^3（ P 〈0. 01）.Conclusion Supervision and management of TVOCs pollution in public places should be strengthened,and health standards should be accelerated to develop for TVOC and other pollutants.
