Partitioning of Cadmium, Copper, Lead and Zinc Among Particulate Fractions and Water in Saginaw Bay (Lake Huron)

摘要

An intensive study of toxic metals in Saginaw Bay (Lake Huron) during 1976-1979 has resulted in a large data base on the temporal and spatial variability of Cd, Cu, Pb and Zn concentrations in both the water and suspended solids. Generally, a trend of decreasing concentrations of both the total and dissolved metals from the inner to the outer bay was observed. Partition coefficients of all the metals studied were not constant with respect to time or space. Particles in the 10-74 micrometers range were found to contain the majority of the particulate metal mass in the water, and they sorbed metals to a higher degree than the other size fractions considered.
