Description: Hydrolysis is an abiotic degradation process that influences the fate of many water-soluble substances in the environment. The ability of chemicals to undergo hydrolysis is currently tested in purified lab water in accordance with OECD guideline 111. It has been suggested that the addition of particles such as sediment or microplastic fibers i.e. may result in a change in the rate of hydrolysis. The project showed that adding commonly occurring particles in aquatic environments can lead to a reduced hydrolysis rate of organic substances, probably especially for sorbing cationic compounds. However, this effect is small compared to the influences known to occur for changes of pH or temperature. Veröffentlicht in Texte | 28/2022.
