Metal bioavailability: EPA workshop identified research needs
Article Abstract:
The cycles of such trace elements as lead and nickel have been changed by human activities. This situation has increased the importance of bioavailability studies, which identify the factors that control the body's uptake of a metal. A Jul 1990 workshop at the Environmental Protection Agency's Environmental Research Center focused on research on the health risks of 10 toxic trace metals. The participants identified a need for better analytical techniques and studies on the levels at which metal intake becomes toxic.

Bioavailability of sedimentary contaminants subject to deposit-feeder digestion
Article Abstract:
The relationship between bioavailability of sedimentary contaminants and digestive biochemical conditions was investigated in benthic animals. The results showed that availability of contaminants in sediments is determined by their solubilization rates. The rates of solubilization of metals under digestive conditions were higher than those predicted by water-solid partitioning with clean seawater.

Mechanisms of Cu solubilization during deposit feeding
Article Abstract:
Complexation enhanced metal remobilization by gut fluids has a significant effect on bioavailability during deposit feeding. Comparisons of copper release potentials of modified and unmodified gut fluids of deposit feeders was measured via microwave treatment. Results show that complexation rather than enzyme action affects bioavailability of copper.
