Sources, Transformation, and Fate of Groundwater Nitrate Under Intensive Anthropogenic Pressures in the Lower Yellow River Basin: Insights From Hydrochemistry and Multi‐Isotope Analysis
Enhanced human activities have increased nitrate contamination in groundwater, threatening water‐supply safety and public health. This study examined nitrate sources and transformation processes in 29 shallow groundwater samples from the lower Yellow River Basin, a region subject to intensive agricultural, industrial,...
