环境中有机含硫芳烃化合物的研究
Study on polycyclic aromatic sulfur heterocycles in the environment
Abstract
有机含硫芳烃化合物（PASH） 性质稳定，不易降解，毒性极强，具有潜在的危害特征。其在环境中的分布，一般是生物体中PASH 的含量最高，其次是大气悬浮颗粒物与海洋沉积物。PASH 的主要来源是石油，分析环境中的PASH 可追踪石油或合成燃料污染。 The polycyclic aromatic sulfur heterocycles (PASH) in the environment is characteristic as the stable nature, not easy to be degraded, strong toxic and potential danger.They distribute generally in the environment and the concentration of PASH in organisms are higher than that in air particulate matter and marine sediments.The main source of PASH is petroleum.Analysis the distribution and concentration of PASH in the environment can trace to the petroleum pollution and/or synthetic fuel pollution.
