| Abstract: | Dissolved mercury in estuarine waters from the Mississippi Delta and Florida Everglades is associated with dissolved organic matter which has the properties of fulvic matter found in soils. Ultrafiltration of water samples demonstrated that mercury and dissolved organic carbon are selectively enriched in the < 500 molecular size cut-off fraction. A decrease in high molecular weight dissolved organic matter with increasing salinity in the Everglades exerts a partial control on the mercury content of these estuarine waters. |
