However, the detoxification ability of AMF to heavy metals in aquatic systems remains poorly understood. This study investigated the effects of AMF on chromium (Cr) distribution and bioavailability in semi-aquatic habitats under different water depths. Results showed that AMF increased the Cr accumulation in the roots of Iris pseudacorus by 10.0–20.0%. Conversely, Cr concentrations in the shoots of AMF inoculated I. pseudacorus were 21.7–68.4% lower than those in the non-inoculated controls. Besides, Cr concentrations and mass contents in water were decreased by 34.1–35.3% and 15.4–23.3% under the low Cr stress (5 mg kg−1) with AMF inoculation compare to the non-inoculated treatments, respectively. Moreover, Cr (VI) concentrations in substrates under the Cr contents of 5 mg kg−1 were 27.0–44.0% lower than those under the non-inoculated controls. Meanwhile, AMF reduced the Cr bioavailability in substrates under the fluctuating water depth (water depth of 6–3 cm), with an acid-soluble state of Cr decreased by 4.1–5.6%. Furthermore, AMF also enhanced the biomass, nutrient contents (TC, TN, Ca, Mg, Fe, and Mn) in the I. pseudacorus under the fluctuating water depth. Therefore, it provides a possibility that AMF can be used to remove heavy metals from polluted wastewater by semi-aquatic habitats under fluctuating water depth (e.g. tidal flow constructed wetlands).
