Occurrence, toxins and possibilities of control of bloom-forming cyanobacteria of European freshwaters: a review | Pojavljanje, toksičnost in kontrola cvetenja cianobakterij v evropskih celinskih vodah: pregled

Inglés. Blooming of cyanobacteria is a common problem of eutrophic water bodies in Europe and worldwide and can cause severe problems with toxicity, taste and odour of the water. Toxins produced by cyanobacteria (cyanotoxins) are structurally diverse and their effects range from liver damage, including liver cancer, to neurotoxicity and thus they may present a serious threat for drinking water safety.  Cyanobacterial blooms present major challenges for the management of rivers, lakes and reservoirs and are predicted to cause even worse problems in the future due to the climate change associated with global warming, increased availability of light to phytoplankton and rising levels of atmospheric CO2. This paper presents the literature review of occurrence, toxins (along with their effects on human health) and possibilities of control of bloom-forming cyanobacteria.

Esloveno. Cvetenje cianobakterij je pogost problem v evtrofnih vodnih telesih v Evropi in po svetu. Povzroča lahko resne težave zaradi toksičnosti, spremenjenega okusa in vonja vode. Toksini, ki jih izločajo cianobakterije (cianotoksini), so po zgradbi različni, njihovi učinki pa zajemajo vse od poškodb jeter, vključno z rakom na jetrih, do nevrotoksičnosti in lahko predstavljajo resno nevarnost pri zagotavljanju varne pitne vode. Cvetenje cianobakterij predstavlja velik izziv za upravljalce rek, jezer in zbiralnikov, predvideva pa se, da bo v prihodnosti ta problematika še naraščala zaradi klimatskih sprememb in z njimi povezanih učinkov globalnega segrevanja, povečane dostopnosti svetlobe za fitoplankton in naraščajočih koncentracij atmosferskega CO2. Članek predstavlja pregled literature o pojavljanju, toksinih (vključno z njihovimi učinki na zdravje ljudi) in kontroli cianobakterijskih vrst, ki cvetijo v evropskihcelinskih vodah.
