污染物同位素数据库

《污染物同位素数据库》主要收集了常见的重金属、硝酸盐等污染物的同位素数据，主要有Pb、Cd、Zn、Cr、Hg、Fe、Cu、S、Sr、13C-土壤有机碳、13C-土壤碳酸盐、15N-硝酸盐、18O-硝酸盐等12种元素的同位素，共计340条数据。数据主要来源于web of science查询的文献。本数据库未对采集的数据进行加工，只是将数据进行了分类。为保证数据的质量，保证每个数据至少有2篇文献的支持。

This is the Pollutant Isotope Database, which primarily collects isotope data of common pollutants such as heavy metals and nitrates. It covers isotopes of 12 elements including Pb, Cd, Zn, Cr, Hg, Fe, Cu, S, Sr, ¹³C-soil organic carbon, ¹³C-soil carbonate, ¹⁵N-nitrate, and ¹⁸O-nitrate, with a total of 340 data records. The data are mainly sourced from literatures retrieved via Web of Science. This database does not perform any processing on the collected data, only classifies them. To ensure data quality, each data entry is supported by at least two literature sources.
