目的检测公共场所挥发性有机化合物(VOC)浓度,了解其分布规律,以及对空气质量的影响。方法 2017年对四类大型公共场所(商场、影剧院、超市、宾馆)室内空气中VOC浓度进行测定和分析。结果四类公共场所中,VOC浓度超标最多的为商场,合格率为70.2%,其浓度最高值主要集中在夏季,冬季和春季浓度值相对偏低。结论 VOC是影响室内空气质量的重要因素,而且可以持续释放。主要来源于建筑物装修材料。绝大部分具有刺激性和毒性,潜在危害着人类健康。它的释放与温度和湿度有关。整合影响VOC的因素,了解针对它的去除方法,提高民众对VOC认知,减少或避免对人们健康的危害。
Objective To detect the concentration of volatile organic compounds (VOCs) in public places, understand its distribution and influence on air quality. Methods In 2017, the indoor air VOC concentrations in four large public places (shopping malls, theaters, supermarkets and hotels) were measured and analyzed. Results Among the four types of public places, the highest concentration of VOC was the mall with the highest pass rate of 70.2%. The highest concentration was concentrated in the summer and the winter and spring concentrations were relatively low. Conclusion VOC is an important factor affecting the indoor air quality, and can be sustained release. Mainly from the building decoration materials. The vast majority are irritating and toxic, potentially harmful to human health. Its release is related to temperature and humidity. Integrate the factors that affect VOCs, understand the ways to remove them, increase people’s awareness of VOCs, and reduce or avoid harms to people’s health.
