摘要：

A new method for determining the distribution of heavy metals in near-shore marine sediments has been investigated. The various sediment components were separated into distinct bands in a density gradient formed from the heavy liquid tetrabromoethane. Direct flame and graphite furnace atomic absorption spectrometry was used to analyze for the low levels of lead, cadmium, and zinc in the density subfractions. Details of the mineralogy and the concentration and distribution of heavy metals in two selected sediment types are given. © 1979, American Chemical Society. All rights reserved.
