Dissimilatory in situ selenate reduction to elemental selenium in sediments from irrigated agricultural drainage regions of western Nevada was measured at ambient Se oxyanion concentrations. Selenate reduction was rapid, with turnover rate constants ranging from 0.04 to 1.8 h-1 at total Se concentrations in pore water of 13 to 455 nM. Estimates of removal rates of selenium oxyanions were 14.38, and 155 mumol m-2 day-1 for South Lead Lake, Massie Slough, and Hunter Drain, respectively.
在内华达州西部灌溉农业排水区沉积物中,于环境硒含氧阴离子浓度下测定了异化原位将硒酸盐还原为元素硒的情况。硒酸盐还原迅速,在孔隙水中总硒浓度为13至455 nM时,周转速率常数范围为0.04至1.8 h-1。南铅湖、马西泥沼和亨特排水渠中硒含氧阴离子的去除率估计分别为14.38和155 μmol m-2天-1。
