摘要 以江苏省南京市某办公室为研究对象,研究了采样环境温湿度、采样点位和采样时间对室内甲醛浓度检测结果的影响。研究结果表明,环境温湿度对室内甲醛含量有明显影响;室内甲醛浓度存在不均匀性,污染源周围的甲醛浓度最高;无太阳直射情况下,采样点宜选择门口位置,有太阳直射情况下,采样点宜选择污染源附近。 Taking certain office of Nanjing as the research object,this paper studied the effects of the envi-ronmental temperature and humidity,the sampling points and sampling time on the indoor formaldehyde concentra-tion.The results showed that the environmental temperature and humidity had obvious effects on indoor formalde-hyde concentration;Indoor formaldehyde distributed uneven,the concentration of site surrounding the pollution source was the highest;sampling points should be near the door without direct sunlight,otherwise should be near the pollution source.
