摘要: 对辽东湾北部浅海区脉红螺生物中Cd、As等重金属元素的全量进行了分析，研究了脉红螺软体中Cd、As等重金属元素分布特征及其与生长环境之间关系.研究表明，脉红螺易于吸收和贮集各种重金属元素，受生长环境影响较大，底泥、海水和海水悬浮物中重金属元素含量高的海域，脉红螺软体内重金属元素含量亦较高.

Abstract: With a total analysis on Cd, As, Pb, Zn, Cu, Hg, Cr and other heavy metal elements in the Papana venosa body from the shallow sea of northern Liaotong Bay, the distribution characteristics of the heavy metal elements and their relation to its growing environment are studied. The result shows that the Papana venosa tends to absorb and reserve heavy metal elements, and is greatly affected by its growing environment. In the sea area where the contents of heavy metal elements in bottom mud, seawater and suspension are high, the content of those is high in the Papana venosa body as well.
