Abstract

In the context of climate change with rising air and water temperatures, and the fact that pesticides are used for different purposes throughout the year and, therefore, at different ambient temperatures, the interaction between chemicals and temperature is of great importance when assessing the risk of pesticides to aquatic organisms. On the one hand, water temperature affects the intrinsic properties of chemicals, such as their solubility, volatility, or biotic and abiotic degradation kinetics. On the other hand, the physiological state and metabolism of poikilothermic aquatic animals is also modulated by temperature resulting in changes in chemical uptake, biotransformation, possible detoxification, excretion, or storage. The BMBF project Glymik therefore investigated the effects of herbicide glyphosate, its main degradation product aminomethylphosphonic acid (AMPA) and the formulation Roundup at different biological levels in juvenile brown trout, including their microbiomes, at different temperatures.
