摘要
在众多海洋突发事故中,尤以石油泄漏最为常见,严重的海上漏油事故往往会对海洋生态环境造成重大损害。石油烃组分复杂,在环境中难以降解,易于在海洋生物体中富集,并且石油烃还具有致癌、致畸和致突变的“三致”效应,对海洋生物的生长、生存和繁殖有严重的影响。本文综述了近年来国内外石油烃组分对双壳贝类毒性影响的相关研究,包括毒性机制、富集规律、对贝类抗氧化酶系统的破坏和基因的影响。最后对双壳贝类中石油烃毒性研究的方向进行了展望,以期为双壳贝类毒性机制和海洋污染修复的研究提供参考。
Oil spills are the most common marine emergencies,and serious marine oil spills often cause significant damage to the marine ecosystem.Petroleum hydrocarbon components in the environment are complex and difficult to degrade.In addition,petroleum hydrocarbons have the three effects of carcinogenic,teratogenic and mutagenic,easy to be enriched in marine organisms,and cause serious impacts on the growth,survival and reproduction of marine organisms.This paper reviews recent studies about the toxicity of petroleum hydrocarbon to bivalve shellfish at home and abroad,including the toxicity of petroleum hydrocarbons,the accumulation rule in bivalve shellfish.In addition,it also includes the impacts on the health of the body,such as the damage of petroleum hydrocarbons to the antioxidant enzyme system in bivalve shellfish,as well as the impacts on the bivalve shellfish genes.At last,the future research direction of petroleum hydrocarbon toxicity to bivalve shellfish are prospected.These results provide references for further studies on toxicological mechanism and marine ecological restoration.
