Pilot testing of a bioremediation system for water and soils contaminated with heavy metals: vegetable depuration module

We present a novel constructed wetland called a vegetable depuration module (VDM) as a pilot test of a bioremediation system (BS) for decontaminating water and soil polluted with heavy metals. The VDM consisted of a pool filled with stones of different granulometry and a substrate top layer composed...
