2. 1. Sediment remediation using activated carbon: amending knowledge gaps

   Author : Robert A. Rämö; Jonas S. Gunnarsson; Agnes M. L. Karlson; Francisco J. A. Nascimento; Barbara Beckingham; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; sediment contamination; sediment remediation; sorbent amendment; activated carbon; benthic community; macroinvertebrates; Baltic Sea; Marine Ecotoxicology; marin ekotoxikologi;

   Abstract : Many coastal sediments have accumulated large quantities of contaminants from past anthropogenic activities and now act as a secondary emission source of legacy pollutants to coastal ecosystems. New sediment remediation strategies are needed to address widespread sediment pollution. READ MORE

4. 2. Tracing anthropogenic Technology Critical Elements using Environmental Forensics : Case studies at Kallholmsfjärden and the Bothnian Bay, northern Sweden

   Author : Stacy Sutliff-Johansson; Anders Widerlund; Kristi Korkka-Niemi; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental Forensics; Technology Critical Elements; Sediment Contamination; Groundwater Contamination; Contaminant Tracing; Tillämpad geokemi; Applied Geochemistry;

   Abstract : The rapidly changing landscape of today's technology industry has increased the number of electronic products being discarded. Society is always on the hunt for the latest product and newest technological advancement, thereby creating a constant influx of older model products into fast-growing waste streams. READ MORE

5. 3. Microbenthos under Pressure : Impacts of human activities on bacteria and meiofauna communities in Baltic soft sediments

   Author : Sven Iburg; Francisco J. A. Nascimento; Owen Wangensteen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; soft sediments; benthic ecosystems; anthropogenic disturbance; contamination; recreational boating; bottom trawling; meiofauna; bacteria; metabarcoding; Baltic Sea; mjuka sediment; bentiska ekosystem; antropogenisk påverkan; förorening; fritidsbåtar; bottentrålning; meiofauna; bakterier; metabarcoding; Östersjön; marin ekologi; Marine Ecology;

   Abstract : The marine benthic zone is one of the largest habitats on the planet, harbouring a large diversity of life that underpin many important ecological processes. However, these habitats have been under growing stress from human activities, profoundly altering their living communities. READ MORE

6. 4. Mobilization of metals from mining wastes and the resuspension of contaminated sediments

   Author : Lan Thuy Nguyen; Bo Svensson; Gunnar Jacks; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acid Rock Drainage; hydropower plant; metal contamination; mining wastes; storm-wind; resuspension; sediment; Environmental chemistry; Miljökemi;

   Abstract : In some environmental situations, environmental effects caused by elevated metals resulting from past mining and smelting activities can be observed in nearby receiving water bodies several decades after mine and smelter closure. There is a growing need for managing the hazardous solid wastes such as mining wastes as well as for assessing water quality and for sustainable management of sediment quality. READ MORE

7. 5. Polychlorinated biphenyls (PCB) in a river ecosystem

   Author : Gudrun Bremle; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrobiology; dredging; landfill; cleanup; remedial action; air; fish; sediment; Persistent organic pollutants; freshwater; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

   Abstract : Atmospheric deposition is one source of persistent pollutants such as polychlorinated biphenyls (PCB) in aquatic environments. Other point sources can also contribute to the PCB loadings in the water. READ MORE
