【正文】 007年秋季對乳山近海海域常見且生物量較大的六種水生動物進行生物殘毒分析的結(jié)果,并結(jié)合國內(nèi)外有關(guān)生物殘毒理論,對乳山附近海域重要漁業(yè)資源重金屬含量現(xiàn)狀進行分析與評價。結(jié)果表明,生物體內(nèi)殘毒量、殘留量指數(shù)I和富集系數(shù)K均因不同海洋動物種類和不同重金屬離子產(chǎn)生明顯的差異。分析結(jié)果也表明,生物體內(nèi)重金屬含量總體上與海水中重金屬含量無顯著的相關(guān)性,這可能與生物對重金屬不同的富集途徑有關(guān)。山東半島。海洋動物。評價Situation and assessment on heavymetal contents in five important marineanimal species in sea area near Rushan, Shandong PeninsulaAbstract:Themarine area offRushan in the middle southern coast of Shandong Peninsula in the South Yellow Sea is an importanfishery , alongwith the speedy economic developmentofShandongProvince, this area hasbeen facing tomore andmorimpactions from the human activities, including the pollutions ofheavymetals. In order to assess the concentration ofheavymetals inmarine animalbody, six monmarine animal species [Octopus variabilis(Mollusca),Oratosquilla oratoria(Crustacea),Portunustrituberculatus(Crustacea),Saurida elongate(Osteichthyes),Pseudosciaena polyactis(Osteichthyes),Enedrias fangi(Osteichthyes)] were collected from the area by trawling fordetection of the contentof seven heavymetals (Zn, Cd, Pb, Cu, Hg, As).Thresults show that the concentrations ofheavymetals in the body of the five species did notexceed the national regressivanalysis sho
