Regulating cumulative impacts on coastal waters

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.
