Effects of aquatic macrophytes on concentrations of contaminents in mesocosms

Research output: Chapter in Book/Report/Conference proceedingAbstract

Abstract

Aquatic macrophytes play important structural and functional roles in aquatic ecosystems. For example, they change their chemical environment by increasing pH and the diurnal variation thereof, cause fluctuations in dissolved O2 levels and produce organic matter, both solid as well as dissolved organic carbon (DOC). Such changes in the chemical environment affect both concentration and speciation of contaminants in aquatic ecosystems. To determine the magnitude of such changes, experiments were conducted to monitor the impact of macrophyte growth form and macrophyte biomass on concentration and speciation of contaminants in various ecosystem compartments, i.e. sediment, plants and surface water. Effects of growth form were studied in a potted-plants experiment performed in mesocosms. The effects of biomass were studied in four flow-through experimental ditches. Concentrations of pesticides (dimethoate, ¿-cyhalothrin, metribuzin and imidacloprid), pharmaceuticals (ibuprofen) and heavy metals zinc (Zn) and copper (Cu) were monitored over time. Concentrations of Cu and Zn diminished rapidly, the decrease
