Approaches and Frameworks for Managing Contaminated Sediments - A European Perspective

摘要: Sediment is an essential, integral and dynamic part of the hydrologic system. In natural agricultural basins, sediment derived from weathering erosion minerals, organic material soils in upstream areas river banks other in-stream sources. As surface-water flow rates decline lowland areas, transported settles along bed by sedimentation. However, because sediments are ultimate reservoir for numerous potential chemical biological contaminants that may be contained effluents originating urban, agricultural, industrial lands recreational activities, contaminated rivers streams, lakes, coastal harbors, estuaries have to pose ecological human health risks. The management quality quantity support socioeconomic goals a cause extensive research, investment regulatory public scrutiny, both Europe internationally. This chapter examines European perspective. first section discusses role achieving ecosystem objectives. Section two summarizes findings EC-funded, demand driven Research Network (SedNet). three describes framework risk assessment major region, Venice Lagoon. next sections describe aspects EC accession country, host country this workshop - Slovakia. four lake contamination related legislation five Persistent Organic Pollutants (POPs), driver six specific class POPs PCBS region Finally, seven some barriers successful management, lists science infrastructure needs address these barriers. Whilst all authors living and/or working Europe, focus on perspectives, much work has benefited international collaborations we feel many observations recommendations will relevance broader audience.
