Algal blooms in freshwater lakes

Cyanobacteria (blue-green algae) are unicellular prokaryotes that thrive mainly in freshwater lakes. Being autotroph organisms they accomplish oxygenic photosynthesis playing a significant role in the food chain of several ecosystems. However, under certain circumstances (eutrophication, climatic change, etc.), they can grow and lead to uncontrolled blooms.

3 months left to stop mouse bioassay for determination of lipophilic marine toxinsThe liquid chromatography-tandem mass spectrometry (LC-MS/MS) is the reference method for lipophilic toxins since July 2011. According to the European Commission EU 15/2011 this method has to be used as matter of routine, both for the purposes of official controls, at any stage of the food chain, and own-checks by food business operators. This legislation applies to European countries and any other exporting to Europe.
