2. 1. Quartz in Swedish iron foundries : exposure and cancer risk

   Author : Lena Andersson; Håkan Westberg; Gunilla Lindström; Per Gustavsson; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Case-control study; crystalline silica; exposure assessment; iron foundry; lung cancer; morbidity; occupational hygiene; respirable quartz; Enviromental Science; Miljövetenskap;

   Abstract : The aims of the studies underlying this thesis were to assess the exposure to quartz in Swedish iron foundries and to determine the cancer morbidity for Swedish foundry workers. A cohort of 3,045 foundry workers and a final measurement database of 2,333 number of samples was established. READ MORE

4. 2. Organic complexing agents for remediation of heavy metal contaminated soil

   Author : Zandra Arwidsson; Bert Allard; Mats Åström; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; soil washing; heavy metals; chelators; recycling; NATURAL SCIENCES; NATURVETENSKAP; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

   Abstract : Soil washing of heavy metal contaminated soil may be enhanced by the addition of synthetic chelators. Since many of these chelators may imply stress to soil organisms and are poorly biodegraded, identification and evaluation of effective biodegradable or recyclable chelators (synthetic and/or naturally produced) is of great interest.

5. 3. Theoretical disputes and practical environmental dilemmas : an interdisciplinary study

   Author : Michelle Benyamine; Per Sandén; Rolf Lidskog; Ola Engelmark; Örebro universitet; []
   Keywords : sustainable development; natural science; theoretical disputes; forest nitrogen fertilisation; constructed wetlands; content analysis; NATURAL SCIENCES; NATURVETENSKAP; Enviromental Science; Miljövetenskap;

   Abstract : The aim of this thesis is to analyse the scientific basis for diverging recommendations in environmental management. A further aim of this study is to discuss the links and interactions between disciplines related to science of environmental issues, and between natural science and practice in dealing with environmental management and ecological sustainability.

6. 4. 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.

7. 5. Enterococcal distribution and responses toenvironmental waters

   Author : Ebraheem M. Elmarghani; Jana Jass; Per-Erik Olsson; Nikolai Scherbak; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Enviromental Science; Miljövetenskap; Mikrobiologi; Microbiology;

   Abstract : The release of antibiotics and pharmaceuticals into environmental waters contribute to the increasing risk of antibiotic resistant bacteria. The spread of antibiotic resistant bacteria in the environment increases the health risks to the community. Enterococci are fecal indicator bacteria (FIB) in aquatic environments for determining water quality. READ MORE
