摘要
在2015年春季对南方某市多个居民住宅、大学校园不同室内及环境空气中甲醛的浓度进行了调查监测,比较分析了不同类型环境中甲醛质量浓度的分布和影响因素,并进行了甲醛的暴露评价,为甲醛的污染防治和人群健康风险规避提供科学依据。结果表明:不同室内甲醛质量浓度均高于室外环境空气的甲醛,居民住宅、校园不同室内甲醛有超标情况,超标率分别为31.3%和27.3%,甲醛质量浓度均值排序与超标率排序相同,居民住宅室内>校园室内场所,反映出2种不同室内环境甲醛排放源的存在和源强的差异;居民住宅室内甲醛质量浓度受装修时间、通风时间、房屋结构、使用功能等因素影响;春季环境空气甲醛质量浓度较高,同时受温度、湿度和降雨等因素影响;大学生甲醛日均暴露量(1.51 mg·h·m^(-3))低于一般居民的(1.74 mg·h·m^(-3)),但甲醛潜在剂量(1.54 mg·d^(-1))高于一般居民的(1.30 mg·d^(-1)),与呼吸速率和所处环境中甲醛分布有关。
In the spring of 2015,the concentration of formaldehyde in indoor and ambient air of various residential and university buildings in a southern city was investigated and monitored.The distribution and influencing factors of formaldehyde concentration in different types of environment were compared and analyzed.This study provided a scientific for the formaldehyde pollution prevention and control of human health risk.The results showed that different indoor formaldehyde concentrations were higher than the outdoor ambient air formaldehyde.The concentration of formaldehyde in residential and campus different indoor exceeded the standard of 31.3% and 27.3%,respectively.Formaldehyde concentration ranking and the same rate of the same rate,residential indoor campus premises,reflecting the two different indoor environment,the existence of formaldehyde emission and source of strong differences.Residential indoor formaldehyde concentration by the decoration time,ventilation time,housing structure,the use of function（1.51 mg·h·m^（-3）） was lower than that of the general population（1.74 mg·h·m^（-3））,and the daily formaldehyde concentration in the ambient air was higher than that in the general population（1.74 mg·h·m^（-3））.But the potential dose of formaldehyde（1.54 mg·d^（-1）） was higher than that of the general population（1.30 mg·d^（-1））,which was related to the respiration rate and the distribution of formaldehyde in the environment.
