Transformation of sediment from mercury reservoir to potential mercury source in drought-stricken wetlands influenced by climate change

) in water samples was higher than the WHO standard value, and high values were detected in plant samples and physicochemical parameters (except pH) in the soil (p < 0.05). The mean contamination and ecological risk indices were also higher in the soil than in the sediment. In the human health risk assessment, the Hazard Index (HI) for both sediment and soil was determined to be <1. Based on the integration of different chemical and analytical approaches, it was concluded that Hg is more mobile and has higher bioavailability for living organisms in the soils of the BMR basin.
