Previously the Strategic Environmental Research and Development Program SERDP had sponsored work on the transport and transformation of munitions compounds MC in coastal aquatic systems. In the area of photolysis, recent work has suggested that the rate of transformation of compounds such as 2,4,6-trinitrotoluene TNT is rapid in seawater, but very little work has been done to determine what products are formed in a salt water environment and the rate at which those products undergo photochemical decay. Rapid transformation rates of some munitions in marine waters, through photolysis, dilution and metabolism, suggest that these munitions may not pose a long term pollution problem. However, if the transformation products are more toxic than the parent compound, then the liability of the Navy remains. In addition if the transformation pathways and rates are not fully characterized in marine systems, the lack of scientific information could lead to poor remediation and management decisions.
