Toxic Cyanobacteria in the Arctic Lakes: New Environmental Challenges. A Case Study
From the beginning of the XXI century, due to eutrophication along with arctic climate warming, algae blooms have become a typical feature in the waters of some areas, along with an increase in the proportion of cyanoprokaryota in the plankton. The presence of toxic cyanobacteria in arctic Imandra Lake (N67,57° E32,89°) have been found since 2006. Sporadic cases of HABs (bloom spots) were caused by cyanobacteria Dolichospermum lemmermannii. Its biomass reached to 85.2 mg/L in bloom spots, where cyanotoxin presence was evaluated using mass-spectrometry method. The profile of the detected toxins was represented by arginine-containing congeners of microcystins (MC-LR, MC-RR and their demethylated forms). In 2017, MC-LR concentration exceeded the WHO standard for drinking water more than twice, which creates new risks to public health especially in drinking and fishery water bodies.
