Résumé

Mobile metal Cu colloids can be formed in periodically flooded paddy soils, potentially aggravating the risks to rice cultivated in these soils. Here, we investigated the formation and fate of Cu colloids in flooded soil as influenced by soil reducible sulfate and temperature. In microcosms with different initial sulfate availability (1.30, 5.34, or 7.38 mmol/kg), we found the treatments with higher sulfate concentrations showed the greater and faster release of metal colloids. Sulfate reduction resulted in the transformation of copper in the colloids from Cu(0) to Cu
