infatma in marine pollution monitoring studies. Mar. Pollut. Bull, 18(11):581-585.

Data on benthic infauna, which are sedentary and respond to pollutant stresses, are important to monitoring programs concerned with the impact of pollutants on human health, marine ecosystems and resources, and decision-making on ocean waste disposal. A review of the attributes of benthic infauna leads to the conclusion that benthic infauna provide site-specific information not readily ob- tained by other means, and that, although sample sorting and taxonomy may be time consuming and costly, should not be omitted from most marine monitoring programs.

1987. Review. Speciation of trace inorganic

contaminants in plants and bioavallability to animals: an overview. J. environ. Qual., 16(4): 289-295.

Experiments designed to determine the behavior of trace elements during xylem transport and subse- quent tissue deposition are reviewed. Differential patterns of cation (Pu, Ni, Cd, and Fe) and anion (Tc, Se, and S) distribution and association with plant metabolites are described and the impact of these processes on gastrointestinal absorption in animals is discussed.

The aims of this review are to show that shorebirds are responsible for rapid rates of heavy metal transfer and for a high proportion of the amounts transferred from benthic intertidal invertebrates back to estuarine waters and sediments; and that seasonal and geographic differences in quantities of metals stored by the birds have little effect on transfer rates.
