1. Ecotoxicological effects on the coral endosymbiont Symbiodiniaceae of organic UV-filter chemicals
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Coral bleaching causes the disappearance of unique ecosystems supporting thousands of different species. The corals health depends on its relationship with its endosymbiont, the zooxanthellate Symbiodiniaceae. This mutualistic relationship can be disrupted by anthropogenic chemical pollution by inducing physiologically stress in Symbiodiniaceae. LÄS MER
2. Leachate-Based Biotic Ligand Model for Soil : Ecotoxicological Risk Assessment of Copper for Invertebrates, Plants, and Soil Microbial Processes
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Environmental pollution of heavy metals has become an increasing problem. Environmental risk assessments can be conducted to investigate and determine the potential risk of polluted terrestrial environments. Traditionally, risk assessments are based on total soil metal concentrations on a dry weight basis. LÄS MER
3. Toxicological screening of imidazolium based ionic liquids
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Ionic liquids are salts that are in liquid form at room temperature. These compounds have been suggested to be environmentally friendly and are proposed to be replacements for commercially available solvents used in laboratory operations today. LÄS MER
4. Comparison of two methods in deriving aquatic predicted no-effect concentration (PNEC) for α-Amylcinnamaldehyde, 1-Tridecanol and Paracetamol
Magister-uppsats, Lunds universitet/Miljövetenskaplig utbildningSammanfattning : This study is evaluating two methods in order to calculate predicted no effect concentrations (PNECs) used in environmental risk assessment for three chemicals (α-Amylcinnamaldehyde, 1-tridecanol and paracetamol). The methods used are Species Sensitivity Distributions (SSD) and the guideline from European Chemicals Agency (ECHA): “Guidance on information requirements and chemical safety assessment”. LÄS MER
5. Effects of early life exposure to flutamide on sexual development in Xenopus tropicalis
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/MiljötoxikologiSammanfattning : 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
