Application of a Hazard-Assessment Research Strategy for Waste Disposal at 106-Mile Ocean Disposal Site (Chapter 14)

摘要

An application of a hazard-assessment research strategy was made using waste disposal at Deepwater Dumpsite-106 (DWD-106) as an example. The strategy involved the synthesis of results from separate exposure and effects components in order to provide a scientific basis for estimating the risk to the aquatic environment. The exposure assessment related source inputs of contaminants to environmental concentration fields through considerations of transport and fate. The effects assessment related environmental contaminant concentration fields to biological effects through considerations of toxicity and bioaccumulation. The implementation of the hazard-assessment strategy for 106-Mile Site was made with the currently available information. Upper bounds on the time-averaged concentration fields for selected contaminants in the water column were developed corresponding to the physical transport patterns that occur in the vicinity of the site.
