Nitrate (NO3−) pollution in rivers caused by intensive human activities is becoming a serious problem in irrigated agricultural areas. To identify NO3− sources and reveal the impact of irrigation projects on NO3− pollution in rivers, the hydrochemistry and isotopes of irrigation water from the Yellow River (IW) and river water (RW), and potential source samples were analyzed. The mean NO3− concentrations...
Mice were fed with source water (SW) and tap water (TW) for 90d to evaluate hepatotoxicity induced by the drinking water. Histopathologic observation showed no obvious damage to hepatic tissue in the SW and TW groups. However, microarray analysis indicated that the SW and TW exposures affected many metabolic pathways, among which PPAR (peroxisome proliferator-activated receptors) signaling was most...
