1. Hazard assessment of ciprofloxacin, sulfamethoxazole and triclosan for marine periphyton : Ecotoxicology, Pollution Induced Community Tolerance and Co-Tolerance
Abstract : Antibiotics and personal care products are used in large quantities and commonly detected in various environmental compartments. The two antibiotics, ciprofloxacin and sulfamethoxazole, and the personal care product triclosan are among the most commonly detected compounds in sewage treatment plants and aquatic environments.

2. The use of protein biomarkers in ecotoxicology Studies of oxidative and genotoxic stress in the blue mussel (Mytilus edulis)
University dissertation from Stockholm : Systemekologiska institutionenAbstract : Many environmental pollutants, heavy metals and polyaromatic hydrocarbons (PAHs) among them, are toxic by oxidative stress. Oxidative stress may be defined as a state in an organism when its inherent capacity to handle oxyradicals is surpassed, and it may result in peroxidation of lipids, and damage to proteins and DNA.

3. Exploring phenomena that affect the fate and impact of radioactive materials in the blue mussel
University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm UniversityAbstract : Current protection of the marine environment from radiation is based largely on measuring, estimating and modelling accumulation and impact(s) of radionuclides in a few marine species. Using a relevant marine organism, this thesis focusses on investigating some poorly described phenomena that could cause deviations from predicted measurements. READ MORE

4. Psychotropic Pharmaceuticals in Aquatic Systems: An Ecological Perspective
University dissertation from Department of Biology, Lund UniversityAbstract : Popular Abstract in English Psychotropic pharmaceuticals include various groups of chemicals that have been designed to affect neurochemistry in human consumers resulting in changes in cognition, mood, and/or behavior; many target specific receptors and subsequently alter neurotransmitter levels in the central nervous system. The use of pharmaceuticals by consumers results in the release of these active substances and their breakdown products into the environment, the main source of which is through domestic wastewater treatment plants connected to households.

5. Environmental pollutants and the reproductive system in birds Developmental effects of estrogenic compounds
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : 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
