2. 1. A step forward in using QSARs for regulatory hazard and exposure assessment of chemicals

   Author : Aleksandra Rybacka; Patrik Andersson; Christina Rudén; Anna Linusson; Uko Maran; Umeå universitet; []
   Keywords : 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;

   Abstract : 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. 2. GARD - Genomic Allergen Rapid Detection. A Testing Strategy for Assessment of Chemical Sensitizers

   Author : Henrik Johansson; Institutionen för immunteknologi; []
   Keywords : In vitro assay. Sensitization. Predictive genomic biomarker signature.;

   Abstract : The modern world is increasingly dependent of the use of chemicals. The chemical industries have greatly contributed to the high standard of living in industrialised societies, and chemical compounds surround us in everyday life. Unfortunately, a vast number of chemicals cause adverse effects on the environment and human health. READ MORE

5. 3. Generation of synthesis gas for fuels and chemicals production

   Author : Per Tunå; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synthetic fuels and chemicals; gasification; gas conditioning; simulation; tar-cracking;

   Abstract : Many scientists believe that the oil production will peak in the near future, if the peak has not already occurred. Peak oil theories and uncertain future oil deliveries have stimulated interest in alternative sources of fuel and chemicals. READ MORE

   Abstract : To fulfill the United Nations’ 17 sustainable development goals, there is a need to transition from a petroleum-based society toward a more sustainable one which requires new solutions and the production of materials, chemicals, and energy from renewable resources. Using side-stream products from industries to produce value-added products will be economically beneficial. READ MORE

7. 5. Exposure, health effects, immunological markers and biomarkers of susceptibility among Swedish rubber workers
