Short-term Effects of Cadmium and Mercury on Soil Nematode Communities in a Pot Experiment.

Analysis of soil nematode feeding groups and functional guilds were used as a valuable tool to detect heavy metal pollution. Effects of cadmium (Cd) at 5 mg/kg, mercury (Hg) at 20mg/kg, combined Cd and Hg at 5+20mg/kg on the nematode communities were studied after three months application. Nematodes were collected from soil in rhizosphere of Morning glories () which were applied as heavy metal accumulators and were grown in the experimental pots.
