Research Abstract

Aquatic ecosystems have many real problems due to anthropogenic impacts. Chemical pollution by pesticides is one contributing factor to these problems.
Population dynamics of the organisms are controlled by complex combinations of biotic interactions and abiotic environmental factors. Vulnerability to the pesticides differs between each species, so the chemicals should induce different community structures. Moreover, the chemicals not only affect the individual survival or the reproduction, but also disturb the prey-predator interactions at very low concentrations.
Here, we have examined the impacts of low level exposure of three pesticides (insecticide, herbicide and bactericide) on freshwater ecosystem by conducting individual-, population- and community level experiments. Our results suggest that pesticides affect significantly on food web structure and ecosystem functions at lower concentrations than PNEC or HC5.
