Atomic Energy Commission— Water pollution 

 emissions are being studied with regard to their effects 

 on biological processes and on organisms. The fates 

 and effects of intermediate and long-lived radio- 

 nuclides are studied in natural systems. Some 

 important nonradioactive nutrients such as nitrogen 

 and phosphorous are also included. Research on fall- 

 out and reactor effluent radionuclide cycling and 

 accumulation in the biota is being conducted in a wide 

 variety of aquatic ecosystems important to man. The 

 combined effects of radiation, temperature, and 

 chemical pollution in surface waters modified by man 

 are being studied. The effects of temperature modifica- 

 tion and chemical additions from a nuclear power plant 

 on the organisms in a shallow subtropical marine bay 

 constitute another area of study.

Department of Transportation— The Coast Guard 

 is studying the physiological responses of mussels and 

 algae to petrochemicals as a possible biological 

 indicator of oil pollution. The fate and behavior of oil on 

 beaches of San Francisco Bay are being studied. 

 Current knowledge is being assessed to determine the 

 potential for using biodegradation processes in 

 cleaning up oil spills in the marine environment and to 

 define specific study areas. 



The Federal Highway Administration is studying the 

 effects of highway deicing chemicals on roadside 

 vegetation and aquatic life and the transport of 

 chemicals by surface runoff and groundwater.

Department of the Interior — Water pollutants are 

 studied to develop criteria for setting water quality 

 standards for the propagation of marine and estuarine 

 fishes, invertebrates and their food chain organisms, 

 and wildlife. The objective is to develop criteria for safe 

 levels of pesticides and pesticide derivatives in 

 estuaries and coastal waters. The effects of organic 

 chemicals, heavy metals, petroleum, and petroleum by- 

 products on estuarine and marine life are being investi- 

 gated. 



The Geological Survey is studying the effects of pollu- 

 tants on ecosystems in certain geographic areas as part
