  2. 1. Change of toxicity during secondary treatment of industrial sludge containing nitroaromatics

    Author : Lillemor Gustavsson; Magnus Engwall; Anna Schnürer; Ulrika Welander; Mårten Jönsson; Bo Mattiasson; Göran Dave; Örebro universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic; aerobic; AhR agonists; CALUX; constructed wetlands; Danio rerio; embryotoxicity; genotoxicity; nitroaromatics; sludge; Environmental engineering; Miljöteknik; Enviromental Science; Miljövetenskap;

    Abstract : Wastewater treatment plants in Sweden are facing a great challenge due to the prohibition of depositing organic waste which gained legal force in January 2005. Biological and commercial available alternatives to disposal are composting and anaerobic digestion. READ MORE

  4. 2. Ozonation as sewage effluent treatment : toxicological effects in adult and embryonic zebrafish, Danio rerio

    Author : Johannes Pohl; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Pharmaceutical residues are not efficiently removed by current sewage treatment plant (STP) technologies. This allows for the release of pharmaceutical residues into the aquatic environment. Pharmaceuticals and their metabolites are problematic because they are designed to affect biological processes in non-target aquatic species. READ MORE

  5. 3. Effects of ozonated sewage effluents and pharmaceuticals in zebrafish (Danio rerio)

    Author : Johannes Pohl; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The aquatic environment is the main destination for many organic pollutants originating from human activity. Pharmaceuticals are significant contributors to this pollutant cocktail. READ MORE

  6. 4. Role of the hERG-channel in arrhythmia and teratogenicity : studies in animal models and the human embryonic heart

    Author : Christian Danielsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Drugs that inhibit cardiac repolarization are associated with potentially life threatening side effects in the form of ventricular arrhythmias in humans. Animal studies show that this mechanism also is relevant for the embryo, and that the circulatory depression results in hypoxia with embryotoxicity in the form of malformations and death as a consequence.

  7. 5. The toxicity of perfluoroalkyl acids in zebrafish (Danio rerio)

    Author : Mazhar Ul haq; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Perfluoroalkyl acids (PFAAs) are globally distributed synthetic chemicals. Their unique properties make them widely used, in industry and elsewhere. These are a group of compounds with varying carbon chain lengths and functional groups. The toxicity evaluation of PFAAs is important to better assess their organismal and environmental impact.
