【摘要】：为研究高校教师办公场所室内灰尘中邻苯二甲酸酯(Phthalate acid esters,PAEs)的污染特征及对人体的健康风险,以哈尔滨市某高校办公室、活动中心和实验室为研究对象,于2015年3月采集、分析了室内灰尘中PAEs的污染水平和组成特征。研究发现,6种PAEs中DEHP的浓度最高(1 881μg·g~(-1)),其次为DBP(451μg·g~(-1));相关性分析发现,DEP和DEHP的浓度与房间面积之间具有显著的负相关性;DEP和DMP的浓度与温度具有显著正相关性;DEP的浓度与湿度具有极显著负相关性。不同房间灰尘中PAEs的浓度具有显著差异性;油漆及粘合剂等装修材料、PVC地板和墙面装饰材料以及个人护理品是室内灰尘中PAEs的主要污染来源。室内灰尘中PAEs的累积暴露风险评估结果表明,青年人群和成年人群对PAEs暴露的健康风险相对较低。
[Abstract]:In order to study the pollution characteristics and health risk of (Phthalate acid (Phthalate acid in the indoor dust of university teachers' office, a university office, activity center and laboratory in Harbin were collected in March 2015. The pollution level and composition of PAEs in indoor dust were analyzed. It was found that the highest concentration of DEHP (1 881 渭 g g ~ (-1),) was found in 6 PAEs (DBP) (451 渭 g ~ (-1); correlation analysis showed that there was a significant negative correlation between the concentration of DBP and DEHP and the area of room.) the concentrations of DEP and DMP were positively correlated with the concentration of temperature. There was a significant negative correlation with humidity. The concentration of PAEs in different room dust was significantly different, and the main pollution sources of PAEs in indoor dust were paint, adhesive and other decoration materials such as floor and wall decoration materials and personal care products. The cumulative exposure risk assessment of PAEs in indoor dust showed that the health risk to PAEs exposure of young and adult population was relatively low.
