1. Developmental exposure to mixtures of environmental pollutants : Studies on metabolism, developmental processes, and reproductive organs in zebrafish and chicken embryos
Abstract : Humans and wildlife are continuously exposed to mixtures of environmental pollutants. Mixture toxicity can be challenging to predict due to interactions between chemicals and thus whole-mixture approaches are crucial in toxicology. READ MORE

2. Environmental pollutants and the reproductive system in birds : Developmental effects of estrogenic compounds
Abstract : A number of environmental pollutants have been shown to mimick the action of the female sex hormone estrogen and are, therefore, suspected to be responsible for reproductive abnormalities seen in wildlife. Test systems which can be used in hazard and risk assessment of chemicals with estrogenic effects are consequently needed. READ MORE

3. Developmental Neurotoxicity of Environmental Pollutants : Effects on neuronal protein markers after neonatal exposure
Abstract : This thesis focused on investigations of the developmental neurotoxic effects of bisphenol A (BPA) or perfluorohexane sulfonate (PFHxS), after a single neonatal exposure, during a critical period of the brain development in mice.BPA is a well-known industrial chemical used in the production of polymer products and PFHxS is used as an industrial additive as a surfactant.

4. Cellular transport and secretion of the cyanobacterial neurotoxin BMAA into milk and egg : Implications for developmental neurotoxicity
Abstract : The cyanobacterial amino acid β-N-methylamino-L-alanine (BMAA) is a neurotoxin implicated in the etiology of neurodegenerative diseases. Cyanobacteria are cosmopolitan organisms present in various environments. READ MORE

5. Evolutionary ecology of ultraviolet-B radiation stress tolerance in amphibians
Abstract : During the last decades many amphibian species and populations have experienced declines and extinctions in different parts of the world. Anthropogenic activities are believed to account for these declines, and one of the hypothesized causes has been the increased level of ultraviolet-B (UV-B) radiation due to depletion of the stratospheric ozone layer.
