Abstract
Assessment of ecological risk for the change in the content of essential polyunsaturated fatty acids (PUFA) in the plankton of lakes under global warming is carried out. The analyzed hazards are temperature, dissolved phosphorus and nitrogen, phyto- and zooplankton structure. The main risks are related not only with temperature increase, but indirect effects of warming. The critical link in risk assessment of PUFA is phytoplankton structure due to the particularly favorable growth conditions for cyanobacteria in nutrient rich waters in shallow lakes and reservoirs.
