As the contamination of freshwater and saltwater ecosystems continues to be reduced through the implementation of regulations governing both point and non-point source discharges, there is a growing emphasis and concern regarding historical inputs and their influence on water and sediment quality. Many locations in urban areas exhibit significant sediment contamination, which poses a continual and long-term threat to the functional condition of benthic communities and other species inhabiting these areas (1)(footnote 2). Benthic communities are an important component of many ecosystems and alterations of these communities may affect water-column and nonaquatic species.
Biological tests with sediments are an efficient means for evaluating
because they provide information complementary to chemical
characterizations and ecological surveys
(2). Acute sediment toxicity tests can be used as screening tools in
the early phase of an
assessment hierarchy that ultimately could include chemical
measurements or bioaccumulation and
chronic toxicity tests. Sediment tests have been applied in both
saltwater and freshwater
environments (2-6). Sediment tests have been used for dredge material
permitting, site ranking for
remediation, recovery studies following management actions, and trend
monitoring. A particularly
important application is for establishing contaminant-specific
