Abstract: [1] Light has been previously shown to play a role in the emission of mercury from soil; however, the mechanisms involved in this process are not well understood. In an effort to identify the wavelength of light that dominates this process, we conducted extensive laboratory studies of soil mercury flux using a dynamic flux chamber. Mercury fluxes were measured at constant temperature in the dark, under full spectrum radiation (l = 320-700 nm) and under various radiation bands including 410-700 nm radiation, 3…
