摘要
内分泌干扰物邻苯二甲酸酯(phthalic acid esters,PAEs)在室内环境中广泛存在.室内灰尘作为一种复杂的环境载体,是许多污染物的源和汇,PAEs吸附在室内灰尘颗粒中可能会带来潜在的健康风险.为了补充东北地区室内灰尘中PAEs的污染信息,并探索PAEs的污染特征和风险水平,在长春高校宿舍采集了 107份冬季灰尘样本和 20份夏季样本,分析了灰尘中PAEs的含量,并进一步研究了PAEs的分布特征、影响因素、潜在来源以及健康风险.结果表明,在冬季,宿舍灰尘中 PAEs的浓度为141.94-1561.06 μg·g-1,其中邻苯二甲酸二(2-乙基己)酯(DEHP)是最主要的PAEs污染物,平均贡献率为 73.62%.装修时间、个人因素以及季节变化都会影响宿舍内PAEs的含量,其中新装修宿舍灰尘中PAEs的含量显著高于旧宿舍,女性宿舍灰尘中PAEs的浓度显著高于男性宿舍,配对的冬季灰尘中PAEs的浓度高于夏季.宿舍灰尘中PAEs的主要来源可能是个人护理品、塑料制品以及纺织品.PAEs的非致癌风险小于 1,在可接受范围内,摄入途径是暴露于PAEs的主要途径.致癌性PAEs,邻苯二甲酸丁苄酯(BBP)和DEHP致癌风险为低风险,DEHP的致癌风险显著高于BBP.
Abstract
The endocrine disruptor phthalic acid esters(PAEs)are widespread in the indoor environment.As a complex environmental carrier,indoor dust is a source and sink of many pollutants,and PAEs adsorbed in indoor dust particles may pose potential health risks.In order to supplement the pollution information of PAEs in indoor dust in Northeast China and to explore the pollution characteristics and risk levels of PAEs,107 winter dust samples and 20 summer samples were collected from university dormitories in Changchun.The levels of PAEs in the dust were analyzed,and the distribution characteristics,influencing factors,potential sources,and health risks of PAEs were further investigated.The results showed that in winter,the concentrations of PAEs in dormitory dust ranged from 141.94 μg·g-1 to 1561.06 μg·g-1,with bis(2-ethylhexyl)phthalate(DEHP)being the most dominant PAEs pollutant with an average contribution of 73.62%.The time of renovation,personal factors,and seasonal changes all affected the levels of PAEs in the dormitories,in which the levels of PAEs in dust in the newly renovated dormitories were significantly higher than those in the old dormitories,the concentrations of PAEs in dust in the female dormitories were significantly higher than those in the male dormitories,and the concentrations of PAEs in the dust in the paired winter months were higher than those in the summer months.The main sources of PAEs in dormitory dust may be personal care products,plastic products,and textiles.The noncarcinogenic risk of PAEs was less than 1,which is within the acceptable range,and the ingestion route was the main route of exposure to PAEs.For carcinogenic PAEs,the carcinogenic risk of benzyl butyl phthalate(BBP)and DEHP was low,and the carcinogenic risk of DEHP was significantly higher than that of BBP.
