Water 78-83 NBL1, DAN family BMP antagonist Homo sapiens 4-7 34581118-11 2021 The NO3-type water occurs in acidic or weakly acidic environments, typically characterized by low TDS and total hardness concentrations, and high Cl-, SO42-, and K+ concentrations. Water 13-18 NBL1, DAN family BMP antagonist Homo sapiens 4-7 34581118-12 2021 The formation of NO3-type water is mainly affected by domestic sewage, industrial wastewater, agricultural nitrogen fertilizer, septic tank outflows, and landfill leachate leakage. Water 26-31 NBL1, DAN family BMP antagonist Homo sapiens 17-20
