Abstract

In August 2022, an environmental catastrophe in the river Oder led to a mass die-off of fish, mussels, and aquatic snails. High electrolyte concentrations from wastewater of the Polish mining industry and low water levels brought about a bloom of the brackish water algae Prymnesium parvum. The toxins (prymnesins) produced by this algae under certain environmental conditions are considered to be the reason of the mass mortality of gill-breathing aquatic organisms. However, extensive studies of the dragonfly fauna on the river Oder in 2023 did not reveal any negative effects of the disaster on this species group. The findings of this analysis are presented and discussed in this paper. [ABSTRACT FROM AUTHOR]
