The occurrence of polycyclic musks in a typically wastewater treatment plant 典型污水处理厂中多环麝香的污染特征
Research Progress in Analytical Methods for Determination of Synthetic Musks in Sludge from WWTP 城市污水厂污泥中合成麝香分析方法的研究进展
Crossing the mountains, trading tea and salt with antlers and musks. 跨过了千山万岭,驮走鹿茸麝香,换来盐巴茶叶。
The experiment has proved that GC-MS was an easy, effective and rapid method for quality identification of different musks. 通过乙醇提取气相色谱-质谱法可简单、快速、有效鉴定不同麝香的品质。
On the basis of above achievements, the methods to separate musks by crystallization were studied. 在相平衡研究的基础上探讨了合成硝基麝香的溶液结晶分离方法。
Polycyclic musks exhibit same properties, hydrophobic and lipophilic, bioaccumulation as polycyclic hydrocarbons ( PAHs) and polychlorinated biphenyls ( PCBs). 多环麝香与多环芳烃、多氯联苯等化合物性质相似,具有较强的亲脂、憎水性,容易吸附在有机物上,在环境中难降解,有很强的生物富集作用,呈现一定的雌激素活性。
Current developments of polycyclic musks are reviewed. 本文综述了多环麝香的当前进展,并提出了系统的分类方法。
Liquid-liquid equilibria data for musk ketone, musk xylene, dimethyl sulfoxide ( or acetonitrile) and heptane ( or cyclohexane) quaternary systems were measured firstly to evaluate the effect of the two liquid phase on the separation of musks mixture. 本文计算并测定了酮麝香、二甲苯麝香、二甲基亚砜(或乙腈)和庚烷(或环己烷)四元体系的液液相平衡,试验结果与计算值基本吻合。
Most studies on environmental pollution from polycyclic musks have been focused on such areas as distribution characteristics, ecotoxicological feasibility and risk evaluation. 对于多环麝香环境污染的研究,主要集中在分布特征、污染程度、生态毒理和风险评价等研究领域。
Polycyclic musks exhibit the same physical and chemical properties as polycyclic aromatic hydrocarbons ( PAHs) and polychlorinated biphenyls ( PCBs), which have a strong lipophilic, hydrophobic and easily gathered in the organic phase. 多环麝香类化合物与多氯联苯和多环芳烃类化合物的物理化学性质相似,它们具有较强的亲脂、憎水性,易在有机相中聚集。
As a cheap substitute of natural musks, polycyclic musks have been widely used as fragrance materials in detergent, cosmetic and perfume. 多环麝香类化合物是天然麝香的一种廉价替代品,它们主要被广泛地应用在洗涤产品,化妆品和香水等日用产品中。
At last, polycyclic musks are bioaccumulated into biotas and human body through food chain. 环境中的多环麝香会通过食物链富集在生物体内和人体内。
