A sediment ecotoxicity assessment platform for in situ measures of chemistry, bioaccumulation and toxicity. Part 2: Integrated application to a shallow estuary

► In situ bioassays help improve linkages between exposure and effects. ► SEA Ring is an in situ assessment tool for characterizing sediment quality. ► In situ bioassays and physicochemical assessment tools can link exposure and effects. ► Groundwater seepage presented limited risk at estuarine sediment site.
