典型污染源中多环麝香的污染特征

The Pollution Character of the Polycyclic Musks in a Typical Cosmetic Plant

合成麝香是一类近十多年才引起人们关注的有机污染物。合成麝香广泛分布于环境中,难降解,易生物富集,对水生生物和人体均呈现一定的生物毒性。文章对某一化妆品厂生产车间内、外及工厂外的上、下风向大气中多环麝香进行了定性定量分析,结果表明,除ATⅡ之外,大气中检测出了五种多环麝香,其中作为对照点的上风向多环麝香总浓度为5.43ng/m^3,而工厂室内、外及下风向的多环麝香浓度范围为17.25-5543.4ng/m^3;气固分配实验研究发现,超过68.43%的多环麝香分布于气相中。

Synthetic musks, exhibiting toxicity to organisms and human beings, were recently detected as a group of pollutants in various environments, which are persistent in the environment and can be bioaccumulated. This paper analysed air samples, which were collected in the workshop, out the workshop, downwind the cosmetic plant and upwind the cosmetic plant. Five polycyclic musks were detected except for AT Ⅱ . The polycyclic musks concentrations were 5.43 ng· m^-3 in the upwind site, while the polycyclic musks concentrations were from 5543.46 to 17.25 ng· m^-3 in the workshop to downwind the cosmetic plant. There are more than 68.43% polycyclic musks presented in the gas-phase.
