Dataset on stable isotopic composition of δ18O and δ15N in nitrate in groundwater, and δ15N in solid matter in the Varaždin area, NW Croatia

The dataset relates to stable isotopic composition of δ18O and δ15N in nitrate in groundwater, and δ15N in solid matter collected in the Varaždin area in NW Croatia. The excel file consist of two sheets: (i) Groundwater and (ii) Solid matter. The dataset is of a multidisciplinary value and can be used by researchers (hydrogeologists, geochemists, microbiologists) working on groundwater contamination related problems and water quality management.

本数据集涵盖克罗地亚西北部瓦拉日丁（Varaždin）区域采集的地下水中硝酸盐的δ18O与δ15N稳定同位素组成，以及所采固相物质中的δ15N稳定同位素组成。该Excel文件包含两个工作表：(i) 地下水 与 (ii) 固相物质。本数据集具备多学科应用价值，可供水文地质学家、地球化学家、微生物学家等从事地下水污染相关研究及水质管理工作的科研人员使用。
