Oxygen and hydrogen isotope ratios in bottled waters

This dataset comprises stable hydrogen (2H) and oxygen (18O) isotope ratio data for bottled waters worldwide. Compiled from peer-reviewed scientific publications, the data include isotopic measurements and associated metadata, providing a comprehensive resource for hydrological, environmental, food authenticity, and forensic research. Developed to consolidate currently dispersed information on the isotopic composition of commercial bottled waters into a single, standardized database, the dataset contains isotope ratio values alongside metadata, such as country, geographic location, water classification, brand name, sampling period, analytical technique, and original bibliographic source, where available. The data were obtained through a systematic review of the scientific literature and harmonized to ensure consistent terminology, metadata structure, and isotope notation. No new experimental measurements were generated; all records originate from published studies. This dataset enables users to compare isotopic compositions of bottled waters across different regions, investigate spatial variability, evaluate relationships with meteoric water signatures, support water provenance and authenticity studies, and facilitate hydrological, environmental, and forensic applications. Additionally, it serves as a reference dataset for meta-analyses, isotope-based modeling, and future investigations into bottled water resources.本数据集收录了全球瓶装水的稳定氢同位素(δ2H)与氧同位素(δ18O)比值数据。该数据集编译自同行评议科学文献，包含同位素测量结果及相关元数据，可为水文、环境、食品真实性及法医研究提供全面的支撑资源。本数据集旨在将当前分散的商业瓶装水同位素组成相关信息整合为单一标准化数据库，收录了同位素比值与各类元数据，包括可获取的国家、地理位置、水类别、品牌名称、采样周期、分析技术及原始文献来源等信息。数据通过系统梳理科学文献获得，并经过统一化处理，以确保术语、元数据结构及同位素标记的一致性。本数据集未生成新的实验测量结果，所有记录均来自已发表的研究。该数据集可支持用户对比不同区域瓶装水的同位素组成，探究空间变异性，评估其与大气降水同位素特征的关联，助力水源溯源与真实性研究，并推动水文、环境及法医相关应用的开展。此外，它还可作为元分析、基于同位素的建模及未来瓶装水资源相关研究的参考数据集。
