  1. 1. Ecotoxicological effects on the coral endosymbiont Symbiodiniaceae of organic UV-filter chemicals

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Nanna Walther; [2022]
    Keywords : Environmental toxicology; Symbiodiniaceae; miljötoxikologi; phytoplankton; UV-filter chemicals; corals; environmental biology; biology; toxicology; chemicals; sunscreen; pollution; ocean; coral bleaching;

    Abstract : 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. READ MORE

  3. 2. Leachate-Based Biotic Ligand Model for Soil : Ecotoxicological Risk Assessment of Copper for Invertebrates, Plants, and Soil Microbial Processes

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Tove Florén; [2021]
    Keywords : Tomato shoot; Barley root; Glucose induced respiration; Nitrification; Earthworm; Springtail; EC10; SSD; Regression analysis; pH dependency; Bioavailability;

    Abstract : 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. READ MORE

  4. 3. Toxicological screening of imidazolium based ionic liquids

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Joakim Stenström; [2020]
    Keywords : biology; molecular toxicology; ionic liquids; imidazolium based ionic liquids; toxicology; environmental toxicology;

    Abstract : 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. READ MORE

  5. 4. Comparison of two methods in deriving aquatic predicted no-effect concentration (PNEC) for α-Amylcinnamaldehyde, 1-Tridecanol and Paracetamol

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Emma Holmén; [2019]
    Keywords : PNEC; Environmental risk assessment; ERA; α-Amylcinnamaldehyde; 1- tridecanol; paracetamol; Species Sensitivity Distributions; SSD; ECHA; Guidance on information requirements and chemical safety assessment; Earth and Environmental Sciences;

    Abstract : 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”. READ MORE

  6. 5. Effects of early life exposure to flutamide on sexual development in Xenopus tropicalis

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Miljötoxikologi

    Author : Christopher Hampton; [2019]
    Keywords : ;

    Abstract : 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. READ MORE
