Poiycyclic aromatic hydrocarbons ( pah ) are priority trace organic pollutants in the clrtap ( convention on long - range transboundary air poliution ) pops ( persistent organic poilutants ) protocol . both laboratory experiments and fie1d surveys unequivocally demonstrated that pah adversely affect estuarine and marine organisms . pah are implicated in the development of iesions and tumors in fish , they produce biochemical disruptions and cell damage that iead to mutations , developmental malformations and cancel although many marine organisms do not exhibit acute responses to pah " exposure , but suffer sublethal effects 本论文以湄洲湾海域和厦门西海域养殖区为研究区域，采用现代分析技术，从分子水平上系统研究了多环芳烃( pah )在海水、沉积物、养殖鱼类中的含量分布：通过现场实验，实验室暂养、投毒和恢复实验系统测定了养殖鱼类的肝脏、胆汁、鳃、全血等不同器官、组织的生化指标及养殖鱼类肝脏、胆汁的化学指标，探讨了这些指标对水环境多环芳烃污染的生物指示作用。
