1. Hierarchical responses to organic contaminants in aquatic ecotoxicological bioassays: from microcystins to biodegradation
Sammanfattning : In this thesis I explore the ecotoxicological responses of aquatic organisms at different hierarchical levels to organic contaminants by means of bioassays. The bioassays use novel endpoints or approaches to elucidate the effects of exposure to contaminants and attempt to give mechanistic explanations that could be used to interpret effects at higher hierarchical scales.

2. From genes to blooms : Diversity in microcystin phenotypes and mcy biosynthesis genes in the cyanobacterium Microcystis
Sammanfattning : Cyanobacterial blooms are increasing in occurrence and frequency world-wide, mainly due to eutrophication and increased water temperatures. In freshwater, Microcystis is one of the most common bloom-forming genera, renowned for producing the toxin microcystin which is harmful to humans and other mammals. LÄS MER
3. Biosensor-based Methods for Detection of Microcystins as Early Warning Systems
Sammanfattning : Cyanobacteria blooms are a water menace since they produce potent toxins that have been implicated in poisonings and deaths of humans and animals after consumption or contact with cyanotoxin-contaminated water. Of particular concern are cyanotoxins called microcystins, which are hepatotoxic cyclic peptides known to promote development of liver tumors in humans and animals. LÄS MER
