The diffusion of 75SeO32− in crushed BsG was slowest at approximately pH 5. The Da values under aerobic conditions were nearly one order of magnitude lower than those under anaerobic conditions. Fe(II)-bearing mineralogical components can be responsible for the great difference in Da values. SeIV can be reduced to Se0 by BsG under anaerobic conditions.
