Summary
A recycling multi-compartment algaeDaphnia magna bacteria microecosystem was used to evaluate the effect of the herbicide diuron. It was found that 0.2 ppm diuron was lethal to theDaphnia magna population in this microecosystem. Diuron had an effect on newly born animals that therefore did not grow up to become adults. It was argued that it was a direct effect on theDaphnia and not an indirect effect because of food shortage.
