Description:In the past, waste materials too toxic or hazardous for disposal on land or in estuaries have customarily been disposed of at sea. Assessment of the risk and consequent environmental harm to the oceans is essential if ocean dumping is to be continued. The author has surveyed the available literature, bioassay studies, and pertinent research concerning chronic effects and the risk they impose on the marine ecosystem. The main purpose of this study was to investigate and define the correlations between acute and chronic toxicities for known hazardous materials. This relationship is vital for the determination of an appropriate safety factor to be used in evaluating allowable discharges or concentrations in the marine environment. The variables that the author defines to be of most importance are: stage of development, concentration of toxicant, time of exposure, specific or non-specific reactions, lifetime of the compound, reactions with other chemicals, and bioaccumulation. The author has determined the ranges of ratios for different conditions and situations or at least the ratios of acute to chronic toxicities for various classes of materials. This will permit the proper scientific thought to be given for the safety factors needed to protect our marine environment.
