Pollution Research 



The pollutant research program includes studies of the 

 transfer and effects of pollutants in the marine environment. The 

 pollutant transfer process program is based in large part on the 

 baseline studies. It is designed to understand the mechanisms 

 that are important in pollutant transfer into and within the 

 environment and the environmental processes affecting these 

 mechanisms. The pollutant effects program will assess and pre- 

 dict the effects of pollutants on marine organisms. 



The goals of the transfer process research program are to: 

 (1) Determine which mechanisms are important in pollutant 

 transfer, (2) determine important environmental factors affect- 

 ing pollutant transfer processes, and (3) identify principles gov- 

 erning transfer of pollutants. Specifically, the quantities and 

 forms of heavy metals, halogenated hydrocarbons, and petro- 

 leum hydrocarbons will be determined at the sea surface and in 

 the coastal regions where they enter the marine environment. 

 Special attention is being paid to the concentration and dispersal 

 of pollutants at the air-sea interface, leakage of pollutants 

 through estuaries to continental shelf waters, and the chemical 

 forms of the pollutants. The chemical aspects of this program 

 involve investigations of how the physical and chemical proper- 

 ties are changed by environmental conditions; the biological 

 aspects focus on the mechanisms of pollutant uptake by orga- 

 nisms and the way pollutants are transferred through marine 

 food chains. Projects within this program are listed in table 1.

Project Title: Determination of the Input and Transport of 

 Pollutant Lead in Marine Environments Using Isotope 

 Tracers 



Grant No.: GX-31293 



Lead is the one toxic metal suspected, with some degree of 

 assurance, of polluting the marine environment. This has be- 

 come evident from comparisons of the amounts of lead in the 

 oceans with the amounts of industrial lead being dispersed into 

 the environment. Lead is unique in that industrial and natural 

 occurrences have different isotopic compositions, so that it is 

 possible to distinguish between these two kinds of lead in the 

 marine environment.
