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
