2. 1. Remediation of materials with mixed contaminants : treatability, technology and final disposal

   Author : Kristin Elgh-Dalgren; Patrick van Hees; Bert Allard; Dan Berggren Kleja; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioremediation; Microtox®; mixed contaminants; re-cycling; soil remediation; soil washing.; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

   Abstract : Contaminated soils are a large issue worldwide and much effort has been made to find efficient remediation methods. At many contaminated sites, mixtures of dif­ferent contaminants with different properties are present, which may lead to addi­tional problems, and thus additional costs, during the remediation process.

4. 2. Endocrine disruption in fish : Effects of 17α-ethinylestradiol exposure on non-reproductive behavior, fertility and brain and testis transcriptome

   Author : Tove Porseryd; Inger Porsch Hällström; Ioanna Katsiadaki; Södertörns högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; 17α-ethinylestradiol; endocrine disrupting chemical; fish; behavior; fertility; transcriptome; RNA sequencing; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

   Abstract : Aquatic environments are the end recipient for most anthropogenic chemical pollutants. One common chemical pollutant found in the aquatic environment is 17α-ethinylestradiol (EE2), a synthetic estrogen used in contraceptive pills. READ MORE

5. 3. Remediation of mercury polluted soil

   Author : Thomas Lifvergren; Bert Allard; Örebro universitet; []
   Keywords : soil pollution; soil remediaion; mercury; NATURAL SCIENCES; NATURVETENSKAP; Enviromental Science; Miljövetenskap;

   Abstract : Mercury in contaminated soil constitutes a wide spectrum of species with highly different properties due to the chemical complexity of the element. Assessments of risk, ecological effects and removal potential require process and mobility studies. READ MORE

6. 4. Leaching of Polycyclic Aromatic Hydrocarbons Using a Column Method

   Author : Anja Enell; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Naturvetenskap; Chemical technology and engineering; Natural science; Miljöstudier; Environmental studies; coal tar; PAHs; desorption; soil; combustion residues; remediation; availability;

   Abstract : Polycyclic aromatic hydrocarbons (PAHs) are a group of organic pollutants of great environmental concern, due to their toxicity, carcinogenicity and long persistence in the environment. To determine the potential risk associated with PAHs released from contaminated soil or waste materials, knowledge is required on the leachable concentrations of PAHs and the amounts available for release.

7. 5. Baltic Sea sediments : Source and sink for metal contamination

   Author : Sina Shahabi-Ghahfarokhi; João Marcelo Ketzer; Alessandro Amorosi; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Baltic Sea; sediments; acid sulfate soil; metal; remediation; reoxygenation; X-ray absorption spectroscopy; Environmental Chemistry; Miljökemi; Miljövetenskap; Environmental Science;

   Abstract : The Baltic Sea sediments record spatial and temporal information about metalsand metalloids (hereafter referred to as metals), which could help to understandthe past and present contamination sinks in different basins. In addition, giventhe expanding anoxic zones in the Baltic Sea, the response of metals to artificialreoxygenation is poorly understood. READ MORE
