Study on the Acute and Chronic Toxicity of Typical Organic Pollutants on Tigriopus japonicus

Abstract

海洋环境中的有机污染问题已成为倍受关注的全球性环境问题,目前亟需开展典型有机污染物对海洋生物毒性效应的研究,为相应的环境风险评价提供依据。桡足类作为海洋生态系统中承上启下的关键动物,研究其个体和种群对环境污染物的响应情况,对污染物的生态效应评价具有重要意义。本研究选择我国近岸海域中被普遍检出且已被我国或其他国家列为环境优先控制的10种有机污染物,包括有机磷农药(毒死蜱、马拉硫磷)、有机氯农药(狄氏剂)、多环芳烃(菲、芘、苯并[a]芘)、酚类化合物(壬基酚)、有机锡化合物(三丁基锡)和多氯联苯(PCB77、PCB126),以日本虎斑猛水蚤为实验对象,测定这些有机物对桡足类动物急、慢性毒性效应,对...The organic pollutants are currently a worldwide concern in the oceanic environment. It needs to carry out the researches on the toxic effects of organic pollutants on marine organisms, which could provide the datas for the corresponding enrionmental risk assessment. Marine copepods are an important group of species with wide range of biogeographical distributions as they serve as essential food s...学位:理学硕士院系专业:海洋与环境学院海洋学系_海洋生物学学号:2242007115085
