摘要：

Seaweed and urchins accumulate Fe and Zn to higher concentrations near a lead/zinc ore body than further away. The concentration of three metals (Cu, Fe and Zn) in seaweed increase with age of tissue. As and Cd are lowest in tissue of intermediate age, suggesting a reversible bonding mechanism for the two elements. Concentrations of Fe in whole urchins, and Zn in the gonads, are higher than concentrations in Fucus tips, which represent a lower level in the food web. Fe is higher in whole sea urchins than in their gonads. For As and Zn the relationship is reversed. © 1979.
