Biochemistry of a Plume of Nitrate-Contaminated Ground Waterf an anoxic core surrounded by a halo of nitrate. The groundwater chemistry indicates that nitrification is limited by oxygen diffusion into the anoxic zone and that denitrification is limited by the available labile carbon. Consequently, natural attenuation of the plume is inhibited and . cleanup strategies are suggested.作者: 向下五度才偏 時(shí)間: 2025-3-22 10:34
