Waters adjacent to major cities, which support several industries such as fishing, tourism, phosphate fertilizers and maritime transport, are threatened by rapid urban, industrial and tourism development. Special attention is required to protect the marine environment against contamination from land-based sources.
Nuclear and isotopic techniques provide a unique source of information for quantifying these contaminants, particularly radioactive traces, pesticide residues, PCBs, petroleum hydrocarbons and toxic metals and for understanding their fate. For example, radionuclide tracers help understand water and sediment dynamics, and dating of sediment cores using radio-analytical techniques is widely used in geochronological studies to investigate pollution histories.
This paper will review major applications of nuclear and isotopic techniques in the marine environment and show how these techniques can produce long-term environmental benefits for sustainable management of marine waters adjacent to large coastal cities.
