for water and biological specimens analyzed for metals by the 

 Skidaway Institute. Measurements for As, Cd, Cu, Pb, and Zn 

 were obtained from Chondrichthyes, crustaceans (crabs, shrimp, 

 spiny lobsters), fish-eating ducks, mollusks (bivalves, snails, squid), 

 mixed phytoplankton, one specimen of porpoise (Tursiops trun- 

 catus), Sargassum, Spariina, teleosts, and zooplankton. 



The University of Rhode Island and University of Connecticut 

 portion of the program was concerned with the analysis and assess- 

 ment of pollutants transported by the atmosphere, specifically the 

 atmospheric particulates that interact with sea-surface materials. 

 Baseline data were obtained for metals in air particulates, organisms, 

 and sea-surface films; for lipids, as pollution indicators, in atmos- 

 pheric particulates and sea-surface films; and for pesticide residues 

 and polychlorinated biphenyls in atmospheric particulates, organ- 

 isms, sea-surface films, and sediments. Figures 10 to 14 show the 

 sampling locations for chlorinated hydrocarbons and lipids in the 

 marine atmosphere and sea-surface microlayer, heavy metals asso- 

 ciated with Northwest Atlantic zooplankton, and trace metals. Sea- 

 surface microlayer samples were collected from coastal, estuarine, 

 and oceanic areas in the Atlantic. Atmospheric particulate samples 

 for trace metals were collected over wide areas of the North At- 

 lantic from a specially constructed bow tower on the University of 

 Rhode Island's RV Trident.
