11. Microbiome Of Ecotoxicity Assays
Abstract : Microorganisms are ubiquitous and present in animal microbiomes, particulates, and colonizable surfaces of test systems. From an ecotoxicological perspective, they are metabolically active biological compartments that respond to test conditions, including test substances. READ MORE

12. Microplastics in the aquatic environment: Insights into biological fate and effects in fish
Abstract : According to the United Nations, plastic pollution in the natural environment has been identified as one of the biggest environmental challenges of this century and has become a cause for an emerging international concern. It has been predicted that up to 12 million tons of plastic waste reach the aquatic environment annually. READ MORE

13. Responses to reduced industrial metal emissions : An ecotoxicological study on Pied Flycatcher (Ficedula hypoleuca, Aves)
Abstract : Metals have been used by humans for thousands of years, and this has resulted in increased concentrations in the biosphere. The environment around point-sources, such as mines and smelters, are of particular concern, as metals may accumulate to high concentrations, and potentially reach levels toxic to the local flora and fauna.

15. Neurotoxic Effects of Dichlorophenyl Methylsulphones Related to Olfactory Mucosal Lesions
Abstract : This thesis deals with the highly potent olfactory mucosa toxicant 2,6-dichlorophenyl methylsulphone (2,6-diClPh-MeSO2) and its non-toxic 2,5-chlorinated isomer (2,5-diClPh-MeSO2). In mice, both substances bind firmly in the olfactory mucosa and the olfactory bulb, which are important components of the sensory system. READ MORE
