The sorption of Acenaphthene and Phenanthrene was characterized by linear isotherm, indicating solute partition between water and the organic phase in soil.
静态实验结果表明,土壤对焦化废水中以UV_(254)为代表的具不饱和键有机物去除主要是分配作用的结果,其吸附速度非常快,且温度的影响很小;土壤对多环芳烃的吸附去除效果明显,其中苊和菲的吸附等温线呈线性。

In this study, the CPE processes of four different kinds of polyaromatic hydrocarbons, acenaphthene, anthracene, phenanthrene and pyrene, with two kinds of silicone surfactants, DC-193 and DC-190, were studied separately, and four different assisting methods for the phase separation of the CPE process including heating at a higher temperature, adding salts, centrifugation and stirring were introduced, respectively.
今利用两种聚醚型有机硅表面活性剂DC-193和DC-190,对蒽、菲、芘和苊四种多环芳烃进行浊点萃取研究,分别使用加热、加盐、离心和搅拌等辅助方法改变相分离过程的速度。通过测定表面活性剂富集相的体积百分率Vs/随时间的变化和最终的萃取率,研究上述四种不同辅助方法对相分离行为和萃取性能的影响。

It is suggested that the metabolism of heterocyclic amines generated from fried fish may be altered by genetic variability of NAT2. The rapid acetylator would increase the heterocyclic amines from pre-carcinogen to active formation.
NAT2多态性与吸烟有交互作用,特别是野生纯合型与吸烟交互作用可使直肠腺瘤复发危险度上升到22.75(95%CI 2.11-244.86,P=0.007),其机制可能为NAT2酶可能参与了烟草中产生的多环芳烃致癌物,从而涉及直肠腺瘤发生。

The results indicated biogenic conversion, petrogenic and pyrogenic were three important sources of PAHs and their contributions were 19%, 24% and 57%, respectively.
由于长江口距离燃烧源较远,与周边的城镇相距甚远,所以长江口表层沉积物中高环多环芳烃含量相对较低,以石油源PAHs污染为主。
