Potential Biological Consequences of Submarine Mine-Tailings Disposal: ALiterature Synthesis

摘要

A review and synthesis of literature pertaining to biological consequences ofsubmarine mine-tailings disposal (STD) was conducted. STD can result in massive sea floor sediment deposition. STD may also increase suspended sediment, trace metals, and residual milling reagents in receiving waters. These perturbations, which are highly site dependent, invariably smother benthic organisms, and could potentially affect or alter fish, plankton, and benthos through acute and chronic toxicity, bioaccumulation, behavioral changes, smothering, derived secondary effects, and habitat alteration. Much of the available information concerning STD is unpublished and limited to a restricted number of sites.
