目的了解天津市和平区主要公共场所甲醛污染状况,为改善公共场所空气质量提供参考。方法 2013年对天津市和平区4类主要公共场所空气中的甲醛浓度进行监测。采用英国PPM公司生产的PPM400ST型甲醛检测仪,按照《公共场所卫生监测技术规范》进行监测,根据公共场所卫生标准评价甲醛合格情况。结果共抽检77家监测点,合计采样311份,合格249份,合格率为80.1%;娱乐场所、美容美发场所、酒店和商场的合格率分别为70.7%、63.4%、86.7%和90.6%,其中娱乐场所和美容美发的合格率明显低于酒店和商场;新开公共场所的合格率(58.1%)明显低于非新开公共场所(86.9%)。结论娱乐和美容美发场所的甲醛污染较重,应加强卫生监管与教育。
Objective To understand the status of formaldehyde pollution in major public places in Heping District of Tianjin, and to provide reference for improving the air quality in public places. Methods In 2013, the air formaldehyde concentration in four main public places in Heping District of Tianjin was monitored. PPM400ST type formaldehyde detector produced by British PPM Company is used for monitoring in accordance with “Technical Specifications for Health Monitoring in Public Places”, and formaldehyde compliance is evaluated according to public health standards. Results A total of 77 monitoring spots were sampled, with a total of 311 samples passing 249 samples with a passing rate of 80.1%. The passing rates of entertainment venues, beauty salons, hotels and shopping malls were 70.7%, 63.4%, 86.7% and 90.6% respectively, Including entertainment and beauty salons pass rate was significantly lower than hotels and shopping malls; newly opened public places pass rate (58.1%) was significantly lower than non-new public places (86.9%).
