to the oceans and the movement and concentration of pollutants 

 in the oceans. Emphasis is on atmospheric and riverine path- 

 ways, and on chemical, biological, and geological processes 

 that affect the distribution and concentration of pollutants. 

 Objectives of studies are to: determine the principal mech- 

 anisms in pollutant transfer, provide information about the 

 alteration of physical and chemical properties of pollutants, 

 determine the environmental factors affecting pollutant trans- 

 fer, and identify the principles governing pollutant transfer. 

 Projects in this program are listed in table 2. 



Baseline data gathering and analyses — sponsored by IDOE 

 and conducted during 1971 and 1972 — measured levels of 

 chlorinated hydrocarbons, petroleum hydrocarbons, and heavy 

 metals. The IDOE Baseline Conference in May 1972 consid- 

 ered findings of baseline measurements and concluded that 

 pollutants, especially polychlorinated biphenyls, DDT, and 

 petroleum hydrocarbons, were being accumulated in coastal 

 and open ocean biota and further study was warranted. Some 

 results and ongoing activities of pollutant transfer projects are 

 simimarized.

Project Title: Effects of Ocean Water on Physico-Chemical 



Form of Heavy Metals 

 Grant No.: GX-37348 



It appears that heavy metals such as copper, zinc, cad- 

 mium, mercury, and lead, when released to some environments, 

 are unavailable for uptake by marine organisms. The portion 

 of marine ecosystems most likely to become contaminated 

 depends upon how the contaminants are transported. Effect 

 of contaminants upon exposed organisms may well depend 

 upon the biological availability of the contaminant and, con- 

 sequently, upon the physiochemical form in which it occurs.
