Periphyton biofilm

Web摘要： Heavy metals can cause a significant damage to submerged macrophytes and affect its periphyton biofilms in aquatic environments. This study investigated the effects of heavy metals such as copper (Cu), lead (Pb), cadmium (Cd) and their mixture on physiological and biochemical responses and ultrastructure characteristics of Vallisneria natans (V. natans). WebThe research interests include physiological effects of environmental stress（including biotic and abiotic) on submerged plants; the inhibitory mechanism of allelochemicals submerged plants on ...
