      This chapter summarizes the physical, chemical, and biological processes that together comprise the science of contaminant bioavailability in soils and sediments. These processes are strongly influenced by a range of site-specific variables, such as soil or sediment composition, contaminants of. Prior to commencing this study, the NRC’s Water Science and Technology Board hosted a one-day workshop in November to assess the need for a NRC study of bioavailability of contaminants in soils and sediments, attended by approximately 25 key experts.

Objectives of this Phase III study were to assess toxicity of sediments, delineate boundaries of highly contaminated areas, and confirm sediment contamination found during the Phase II study.

Obhodas J(1), Valković V. Author information: (1)Ruder Bosković Institute, Zagreb, Croatia. [email protected] The distribution of major and trace elements in the coastal sea sediments along the Eastern Adriatic coast was evaluated. Differences were observed between the eastern Atlantic and the North Sea sites, with the former showing consistent declines and the latter having stable or rising concentrations for some congeners.

Trends of PCBs in harbour porpoises in UK waters showed declines until mids and stable levels ever since (Jepson et al., ). The baseline toxicity of the pore water from station 8 sediment during (for the North Sea sediments) requires further investigation as it might conceal any contaminants not analysed for so far, yet related to the observed toxicity outcomes.

Monitoring data have been utilised to examine how well sedimentsreflect changes in industrial discharges of metals over aim was to assess the role of selective transport andsedimentation in regulating the spatial distribution of themetals in the sediments, and how this could affect trendmonitoring.

The results showed a significant decrease insediment concentrations of zinc, lead. contaminants in the bottom sediments may be released back into water or enter the food chain. Consequently, bottom sediments are a sink as well as a source of contaminants in the aquatic environment.

These contaminants may pose a high risk to the environment on a large scale and hence need to be monitored at regular intervals.
