Aquatic eutrophication, often with anthropogenic causes, facilitates blooms of cyanobacteria including cyanotoxin producing species, which profoundly impact aquatic ecosystems and human health. An emerging concern is that eutrophication may interact other environmental changes thereby lead to unexpected cascading effects on terrestrial systems. Here, we synthesize recent evidence showing the possibility accelerating will spill over from atmosphere via "air eutrophication", a novel concept refers process promoting growth airborne algae, some them capacity produce toxic compounds for humans organisms. Being catalyzed by various forcings─including climate warming, air contamination, artificial light at night─accelerated be expected in future, posing potentially increasing risk threat public health environment. So far knowledge this topic sparse, therefore consider important research field propose an agenda cross-discipline research. As contribution, have calculated tolerable daily intake 17 ng m–3 day–1 nasal microcystins humans.

Winter cyanobacterial blooms have become increasingly common in eutrophic lakes advocating a need for their monitoring and risk assessment. The present study evaluated the toxicity of winter bloom eutrophicated freshwater lake located Western Poland. was dominated by potentially toxic species: Planktothrix agardhii, Limnothrix redekei, Aphanizomenon gracile. toxin analysis revealed presence demethylated forms microcystin-RR microcystin-LR ranges 24.6–28.7 6.6–7.6 µg/L, respectively. sampled water further platelet-rich plasma isolated from healthy human subjects using lipid peroxidation lactate dehydrogenase assays. No significant adverse effects were observed. demonstrates that some temperate zone, like Lubosińskie Lake, may not exhibit health risks despite microcystin production.
