Photochemical Formation of volatile mercury in high Arctic lakes
Abstract Formation rates of dissolved gaseous mercury (DGM were measured in three high (74 °N) Arctic lakes and one wetland. The rate of formation of DGM was controlled by (1) the intensity of solar radiation, particularly ultraviolet‐B (280–320 nm) and ultraviolet‐A (320–400 nm) wavebands and (2) t...
