Nitrate pollution represents one of the most important issues for ground and surface water quality and source identification is essential for developing effective mitigation practices. Nitrate isotopic fingerprinting can be utilized to identify the sources of nitrate pollution in aquifers. However, it is crucial to assess the performances (precision and accuracy) of the analytical procedure applied to measure the δ¹⁵N and δ¹⁸O values of nitrates from field samples to correctly apply this tool.

在硝酸盐源分配的框架内表征硝酸银法测量δ15N和δ18O的分析性能

硝酸盐污染是地下水和地表水质量最重要的问题之一，而源头识别对于制定有效的缓解措施至关重要。硝酸盐同位素指纹图谱可用于识别含水层中硝酸盐污染的来源。但是，它是评估分析方法的性能（精度和准确度）的关键应用来测量δ ¹⁵ N和δ ^18个从现场样品硝酸盐O值正确地应用此工具。
