What is it about?
EDTA increases the bioavailability of metal pollutants in soil, and has potential applications in phytoremediation. This study investigates whether the addition of EDTA to soil increases the uptake of metals by earthworms.

Why is it important?
Results show that EDTA increases the uptake of certain metals by earthworms. If phytoremediation is to be developed as a treatment for polluted soil, there are implications for earthworms which must be considered.
