Fig. 5: Relationship between sulfate (SO42‒), dissolved organic matter (DOM), and methylmercury (MeHg).

Three-dimensional scatter plot between the surface water concentration of SO42‒, DOM absorbance at 254 nm (DOM α254), and concentration of filtered methylmercury (f.MeHg) in surface water across water conservation area 2A (WCA-2A), WCA-3A, and the Arthur R. Marshall Loxahatchee National Wildlife Refuge (LOX).
