牡丹江市工业区麻雀体内重金属残留分析

Heavy Metal Contents in Organs of Sparrow in Mudanjiang

摘要: 2006年8月至9月,捕捉并测定了牡丹江市工业区与绿化区(对照区)麻雀(Passer montanus)羽毛、肝脏、胸肌和心脏中镉(Cd)、铅(Pb)、铜(Cu)3种重金属残留量。分析结果表明,工业区麻雀组织中重金属残留量高于绿化区。麻雀胸肌、心脏和肝脏中Cd与Pb残留量均呈极显著相关(PPb>Cd。心脏对Cu和Cd、羽毛对Pb均具有较高的富集作用。

Abstract: In August and September,2006,sparrows were caught from an industrial zone and a green area in Mudanjiang for analysis of heavy metal (Cd,Pb and Cu) contents in their feathers,livers,breast muscles and hearts. Results show that sparrows living in the industrial area have higher concentrations of heavy metals. Cd content is significantly correlated with Pb content in breast muscle,heart and liver (PPb>Cd. Hearts have higher Cu and Cd accumulation,while feathers higher Pb accumulation.
