Regulating cumulative impacts on coastal waters

Research

Science and Information Technology

Society and economy

Sediment in ports and marinas typically contain high levels of various hazardous substances from sources related to shipping and leisure boating. When ports are dredged, this material need to be disposed of. In Sweden, all dumping of waste and sediment in the territorial zone and economic waters is prohibited unless it can be showed that it can be done without harm to human health and the environment. This seminar will discuss various methods for assessing the environmental hazard of dredged sediment and will analyze the environmental risks associated with dumping of sediment in coastal marine environments.

Hazardous substances in marinas can originate from sources related to shipping and leisure boating, such as the use of antifouling paints (e.g., organotin compounds like tributyl tin, TBT) and copper, and from the combustion of marine fuels, including polycyclic aromatic hydrocarbons (PAHs).
Currently, the most common practice for assessing the potential
environmental hazard of sediment is comparing measured
concentrations of hazardous substances with criteria set by the Swedish Environmental Protection Agency, which is based on
deviations from background concentrations.
This method has limitations as it lacks a connection to
ecotoxicological effect data.
