Where Brimstone Meets Quicksilver: Interactions between Agricultural Sulfur Applications and Methylmercury Production along a Vineyard to Wetland Gradient
) over a 48 h time period were approximately ten times higher in the wetland compared to the vineyard. Stimulation of Hg methylation in the wetlands and drainage ditch is likely driven by wet, reduced soil conditions. These results show that while Hg methylation is possible in vineyards and adjacent land covers, downstream drainage ditches and wetlands-which intercept sulfate added in vineyards-may be the most notable zones for MeHg production.
