Polycyclic aromatic hydrocarbons (PAHs) are widely distributed in the environment. While environmental concentrations are generally below acutely lethal levels (Hyland and Schneider 1976), chronic, low level exposures may result in subtle sublethal effects. PAHs accumulate in bottom sediments and may represent a hazard to the benthos. Polychaetes are important members of this community (Officer and Lynch 1989). The objective of this study is to evaluate the chronic sublethal effects of one PAH, phenanthrene (PHN), on the polychaete worm, Nereis (Neanthes) arenaceodentata. PHN was selected because of its high toxicity to marine invertebrates relative to other PAHs (Neff 1979).
多环芳烃（PAHs）广泛分布于环境中。虽然环境浓度通常低于急性致死水平（海兰德和施耐德，1976年），但长期低水平暴露可能会导致细微的亚致死效应。多环芳烃会在底部沉积物中积累，并可能对底栖生物构成危害。多毛纲动物是这个群落的重要成员（奥菲克和林奇，1989年）。本研究的目的是评估一种多环芳烃菲（PHN）对多毛类蠕虫沙蚕（Neanthes arenaceodentata）的慢性亚致死效应。选择菲是因为相对于其他多环芳烃，它对海洋无脊椎动物具有较高的毒性（内夫，1979年）。
