在电子电器制造业中，PAHs通常是作为塑料添加剂进入生产环节中，如塑料粒子在挤塑的时候，和模具之间存在黏着，此时要加入脱模剂，而脱模剂中可能含有PAHs。PAES主要是用做增塑剂，增塑剂是一种加入到材料(通常是塑料、树脂或弹性体)中以改进它们的加工性、可塑性、柔韧性、拉伸性的物质。其作用主要是减弱...
Overall, the PAEs and PAHs concentrations gradually decreasing in the offshore and southward directions: their compositions and distributions suggest they could have mainly derived from the Yangtze River. In particular, their distribution was influenced by the sources' proximity, hydrodynamics, and ...
广州垃圾填埋场周围水体中PAHs和PAEs的污染特征 陈迪云;龚剑;褚红榜 【摘要】目前填埋处置仍是城市生活垃圾处理的主要措施之一,而填埋处置产生的垃圾渗滤液可能对填埋场周围水体产生有机物污染.以广州的李坑和兴丰2个代表性的垃圾填埋场为对象,调查垃圾渗滤液中多环芳烃(PAHs)和邻苯二甲酸酯(PAEs)的浓度水平以及...
PAHs)和邻苯二甲酸酯(PhthalicAcidEsters,PAEs)作为环境中广泛存在的两 类疏水性有毒有机物,在水体沉积物中普遍存在。因此深入研究松花江流域表层 沉积物中PAHs和PAEs的分布特征及生态风险对松花江周边居民健康及生态环 境保护具有重要意义。 本论文以松花江全流域为研究区域,美国环保署优先控制的16种PAHs和 6种PAEs...
The ecological risks posed by PAHs in the study are negligible, especially for BaA, which might cause frequent ecological risks to exposed organisms. The order of the PAEs' possible environmental risks was DEHP > DBP > DEP > DMP, and none of them are harmful to se...
Intense PAEs sources were evidenced, but outdoor sources also influenced the I/O ratios. Both the PAHs and PAEs inhalation risk estimations demonstrated that there is a non-negligible potential cancer risk for children in their school environment....
Total PAEs, dominated by bis(2-ethylhexyl)phthalate (DEHP) and di-n-butyl phthalate (DBP), were found at much higher concentrations than PAHs and OPAHs, and their outdoor versus indoor distribution followed that of PM2.5, ranging from 622.0 ng m outdoors, to 808.6 (A) and 864.7 ng...
种PAEs(邻苯二甲酸二甲酯DMP,邻苯二甲酸正二丁酯DBP,邻苯二甲酸正二辛酯OnOP,邻苯二甲酸(2-乙基己)酯DEHP,邻苯二甲酸丁基苄基酯BBP),PAHs总量在0.48～3.07μg/L,平均值为1.83μg/L,PAEs的平均值在0.35～92.63μg/L之间,检出率最高的是DBP,DEHP,萘,菲,芴,芘(检出率100%).在处理过程中,PAHs和PAEs的...
The method is simple and convenient to operate, has the advantages of low detection limit and good repeatability, and is applicable to detection of PAHs and PAEs in plant extracts.孔祥虹何强王宏邹阳CN103389348A * Aug 1, 2013 Nov 13, 2013 陕西出入境检验检疫局检验检疫技术中心 Method for ...
