1. 1. Chemicals in consumer products : Bridging the gap between academic research and chemicals regulation

   Författare :Linda Molander; Christina Rudén; Magnus Breitholtz; Laura N. Vandenberg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; consumer products; articles; chemicals; chemicals regulation; REACH; risk management; health risk assessment; non-standard toxicity studies; study evaluation; reporting guidance; endocrine disrupting compounds; bisphenol A; low dose effects; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Exposure to chemicals emitting from consumer products, such as clothes, electronic devices, toys and kitchen-ware, has emerged as an issue of public health and environmental concern. The use of chemicals having endocrine disrupting properties in commercial products is receiving particular attention as low dose exposures of such chemicals have been associated with adverse effects in both human and wildlife populations.

3. 2. Chemicals in consumer products : Towards a safe and sustainable use

   Författare :Linda Molander; Christina Rudén; Sven Ove Hansson; Mattias Öberg; KTH; []
   Nyckelord :consumer products; articles; hazardous chemicals; risk management; chemicals regulation; REACH; substitution; regulatory toxicology; European Union;

   Sammanfattning : Health and environmental risks associated with emissions of hazardous chemicals from articles, including everyday consumer products such as clothes and toys, have become widely acknowledged internationally, particularly in the EU. This thesis contributes to new understandings of how these risks are currently managed within the EU and recommends actions for ensuring a safe and sustainable use of chemicals in articles. LÄS MER

   Sammanfattning : This thesis focuses on exacerbating chemicals risk in workplaces under the background of rapid industrialization in developing countries. The overall aim is to investigate the development of regulatory tools which aim at minimizing the health risks from chemical substances in the workplace. LÄS MER

5. 4. In silico Identification of Thyroid Disrupting Chemicals : among industrial chemicals and household dust contaminants

   Författare :Jin Zhang; Patrik Andersson; A. Elisabeth Sauer-Eriksson; Liang-Hong Guo; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Thyroid disruption chemicals; virtual screening; tranthyretin; thyroid hormone receptor; QSAR modeling; molecular docking; molecular dynamics;

   Sammanfattning : Thyroid disruptions by xenobiotics have been associated with a broad spectrum of severe adverse human health effects, such as impaired brain development and metabolic syndrome. Ingestion of indoor dust and contact with industrial chemicals are two significant human exposure routes of thyroid hormone disrupting chemicals (THDCs), raising serious concerns for human health.

7. 5. From Science to Policy : Improving environmental risk assessment andmanagement of chemicals

   Författare :Marlene Ågerstrand; Christina Rudén; Magnus Breitholtz; Misse Wester; Andreas Kortenkamp; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; environmental risk assessment; chemicals; pharmaceuticals; transparency; predictability; accuracy; consistency; voluntary initiatives; ecotoxicity data; reliability evaluation; relevance evaluation; non-standard test data; CSR; risk management.;

   Sammanfattning : A complex process like risk assessment and the subsequent risk management decision makingshould be regularly evaluated, in order to assess the need to improve its workings. In this thesisthree related matters are addressed: evaluation of environmental risk management strategies,evaluation of environmental risk assessments, and how ecotoxicity data from the open scientificliterature can be used in a systematic way in regulatory risk assessments.
