Biochar, over the last two decades, has become the focal point of agro-environmental
research given its unique functionality, cost-effectiveness and recyclability potentials. It has …

准确识别水体中硝酸盐污染来源至关重要, 目前稳定同位素已被广泛应用于水体硝酸盐污染源
解析研究, 但关于同位素分馏影响源解析结果准确性的研究仍不足. 介绍了稳定同位素分析技术 …

The vulnerability of semi-arid basin aquifers to long-term salinization due to the dissolution
of groundwater chemical constituents is a major global problem. Despite this, resilient …

Groundwater quality is generally better than surface water quality but this is not sacrosanct
because during recharge and abstraction, groundwater may be subjected to variations due …

Karst water as the vital water supply source is generally suffered from NO 3–contamination
in intensive agricultural areas worldwide. Identifying NO 3–sources and transformations is …

Human activity has doubled the turnover rate of the terrestrial nitrogen cycle, leading to a
series of environmental problems. A little-studied nitrogen source in terrestrial and aquatic …

The external nitrogen load input caused by human activities exacerbates the eutrophication
process of aquatic ecosystems in mining areas, causing water quality problems. However …

Fertilizers increase agricultural productivity and farmers' income. However, intensive
agriculture frequently overuses fertilizers, which in turn can contaminate surface and …

The coexistence of nitrate and endocrine substances (EDCs) in groundwater is of global
concern. Herein, an efficient and stable polypyrrole@ corn cob (PPy@ Corn cob) bioreactor …

Identifying the sources and transformations of riverine nitrate plays a critical role in mitigating
nitrogen enrichment of river networks. Several previous studies have used δ 18 O-NO 3− to …
