1. 16. Application of the benchmark dose-response modelling approach for risk characterization of chemicals

   Författare :Antero Vieira da Silva; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Toxicology is the discipline that investigates the possible adverse effects of chemical exposure on human, animal and environmental health. Chemical risk assessment is the process that aims to identify potentially hazardous substances and describes the probability of adverse outcomes associated with their exposure. LÄS MER

3. 17. A step forward in using QSARs for regulatory hazard and exposure assessment of chemicals

   Författare :Aleksandra Rybacka; Patrik Andersson; Christina Rudén; Anna Linusson; Uko Maran; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; QSAR; in silico; non-testing tools; risk assessment; exposure assessment; hazard assessment; carcinogenicity; mutagenicity; reproductive toxicity; endocrine disruption; estrogen; androgen; transthyretin; sorption; Environmental Science; miljövetenskap; Computer Science; datalogi; Toxicology; toxikologi; Statistics; statistik;

   Sammanfattning : According to the REACH regulation chemicals produced or imported to the European Union need to be assessed to manage the risk of potential hazard to human health and the environment. An increasing number of chemicals in commerce prompts the need for utilizing faster and cheaper alternative methods for this assessment, such as quantitative structure-activity or property relationships (QSARs or QSPRs).

4. 18. Environmental Assessment of Alternative Durable Water Repellent Chemicals. First steps towards a holistic assessment

   Författare :Hanna Holmquist; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LCA; diffuse emissions; wax; silicones; risk assessment; DWR; PFAS; CAA; dendrimers;

   Sammanfattning : Durable water repellent (DWR) finishes are applied to textiles to impart water and in some cases oil repellency. Water (and oil) repellency can be an important contribution to a textile’s performance, for comfort or for the protection of human lives under extreme conditions. LÄS MER

5. 19. Microplastics in the marine environment and the assessment of potential adverse effects of associated chemicals

   Författare :Christine Schönlau; Anna Kärrman; Magnus Engwall; Magnus Breitholtz; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microplastics; reporter gene bioassays; sorption; HOCs; polyethylene; polypropylene; polystyrene;

   Sammanfattning : During the last decade plastics have gained interest by scientists as emerging pollutants particularly in the marine environment due to their ubiquity and persistence. While several studies report the occurrence of microplastics in surface waters globally, there are no harmonized methods to sample and measure microplastics, and the knowledge of toxicological effects in the marine ecosystem is scarce.
