**6.3 Rhizosphere and mycorrhiza**

The release of plant eluates into the mycorrhizal is part of the symbiosis between the plant and the mycorrhizal fungi promoting the plant's uptake of nutrients and the growth of microorganisms in the mycorrhizal area. Its secondary effect of enhanced microbial biodegradation and detoxification of PBDEs in the mycorrhizal area was shown several times in literature. As an example, increased depletion of 470 ng g DM−1 towards 2250 ng g DM−1 was observed for BDE-209 comparing rice plants with and without mycorrhizal fungi [57].
