1. Analysis of DNA methylation changes and behavioural outcomes in adulthood induced by prenatal exposure to a mixture of endocrine disrupting chemicals
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Endocrine disrupting chemicals, or EDCs, are some of the most prevalent toxic chemicals found in the environment because of human activity and they have a variety of adverse effects on both humans and wildlife. A proposed mechanism through which EDCs can negatively affect an organism is via an epigenetic mechanism known as DNA methylation, which can affect the development of the organism with negative outcomes later in life.

2. Evaluation of Pre-Analytical Processes on Lipemic Whole Blood Samples Used in Forensic Toxicology
University essay from Linköpings universitet/Institutionen för fysik, kemi och biologiAbstract : Introduction: Post-mortem whole blood samples differ greatly in quality, lipemia is one cause of concern in toxicological analyses. Around 4 % of all samples sent to RMV are given a notation of lipemic content. READ MORE

3. Ecotoxicological effects on the coral endosymbiont Symbiodiniaceae of organic UV-filter chemicals
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : 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

4. 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 teknikAbstract : 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

5. Using effect-based methods to evaluate the presence of bioactive compounds in food contact materials made of paper and cardboard
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Food contact materials are materials that are intended to come into contact with food, and we are exposed to different types of chemicals that exist in the packages on a daily basis. In this study, a battery of effect‑based in vitro cellular bioassays was used to evaluate the presence of bioactive compounds in commonly used food contact materials made of paper and cardboard, retrieved from the Swedish market.
