  1. 11. 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).

  3. 12. In silico tools in risk assessment : of industrial chemicals in general and non-dioxin-like PCBs in particular

    Författare :Mia Stenberg; Patrik Andersson; Miriam Jacobs; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemometrics; industrial chemicals; in silico tools; molecular descriptors; non-dioxin-like PCBs; partial least-squares PLS ; principal component analysis PCA ; quantitative structure-activity relationship QSAR ; REACH; risk assessment RA ; statistical molecular design; structure-activity relationship SAR ;

    Sammanfattning : Industrial chemicals in European Union produced or imported in volumes above 1 tonne annually, necessitate a registration within REACH. A common problem, concerning these chemicals, is deficient information and lack of data for assessing the hazards posed to human health and the environment. LÄS MER

  4. 13. When water becomes a threat : Risk assessment and risk management plans for floods and drinking water in Swedish practice

    Författare :Viveca Norén; Kevin Bishop; Beatrice Hedelin; Lars Nyberg; Sven Halldin; Kurt Petersen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Flood; Drinking water supply; Risk management; Risk assessment; Flood risk management plan FRMP ; Integrated flood management IFM ; Tools and methods; Practice compared to theory; Sweden; Municipalities; Interview study; Document study; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

    Sammanfattning : Water is an essential but vulnerable resource. A shortage of good quality drinking water is a threat to human health and society as a whole. Abundance of water in the form of floods can also be a serious threat which can have consequences for the drinking water supply. To reduce these risks there is a need for systematic risk reduction.

  5. 14. Life cycle assessment of electric vehicle batteries and new technologies

    Författare :Mats Zackrisson; Magnus Wiktorsson; Martin Kurdve; Christina Jönsson; Anders Nordelöf; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle assessment; LCA; electric vehicle; sustainability; eco-design; Production Engineering; Industriell produktion;

    Sammanfattning : Electrification of vehicles has for decades been explored as a possible solution to the problem of climate change. Today, in 2021, the issue is no longer whether the electrification of vehicle fleets ought to happen but rather how it can be achieved with as little environmental impact as possible. LÄS MER

  7. 15. Uncertainty, variability and environmental risk analysis

    Författare :Monika Filipsson; Tomas Öberg; Bo Bergbäck; Lars Rosén; Linnéuniversitetet; []
    Nyckelord :Contaminated land; exposure assessment; exposure factors; risk analysis; risk perception; uncertainty; variability; probabilistic risk assessment; NATURAL SCIENCES; NATURVETENSKAP; Miljövetenskap; Environmental Science;

    Sammanfattning : The negative effects of hazardous substances and possible measures that can be taken are evaluated in the environmental risk analysis process, consisting of risk assessment, risk communication and risk management. Uncertainty due to lack of knowledge and natural variability are always present in this process. LÄS MER
