1. 11. Establishment of analytical methods to assess endocrine disrupting compounds in a swedish wastewater treatment plant : water sampling using the Novel TIMFIE Device

   Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

   Författare :Annika Niemeyer; [2019]
   Nyckelord :organic micro-pollutants; steroid hormones; mass spectrometry; influent and effluent waters; chemical releases;

   Sammanfattning : Imagine one drop of food coloring in 70 million liters of water. This low concentration equals one nanogram per liter, which is the level most steroid hormones are effective at. LÄS MER

   Sammanfattning : Pharmaceuticals and personal care product (PPCPs) substances has been detected in various water bodies in Sweden. A substantial part of these compounds are spread in nature due to insufficient removal in water treatment plants. LÄS MER

4. 13. Effects of early life exposure to flutamide on sexual development in Xenopus tropicalis

   Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Miljötoxikologi

   Författare :Christopher Hampton; [2019]
   Nyckelord :;

   Sammanfattning : While endocrine disrupting chemicals have become a serious concern in human and environmental toxicology, many of the methods used for investigating developmental toxicity require long exposure periods, and thus can be technically challenging, labour intensive and expensive. For example, the current standard method, the Larval Amphibian Growth and Development Assay (LAGDA) has an exposure period of ³130 days. LÄS MER
