2020-2021年鄱阳湖流域水体硝酸盐污染物数据

在鄱阳湖流域，开展了长达1年（2020/06-2021/06）的多位点（未污染源水区、轻度污染区及重度污染区），多对象（水、土、蔬菜及鱼类），多时间尺度（周，月及季度），（从污染源到污染对象）全链条野外现场采样，所有采集的样品都具有代表性、可靠性及可验证性；根据国家标准（GB）方法，及本团队开发的已经获得国际专利的分析方法，测定了样品中硝酸盐、亚硝酸盐等N素载体浓度及氮、氧同位丰度，所有结果都具有可靠性，高精度及可重现性。该数据集为2020-2021年鄱阳湖流域土壤硝酸盐污染物数据

A 1-year (from June 2020 to June 2021) multi-site (uncontaminated water area, lightly contaminated area, and heavily contaminated area), multi-matrix (water, soil, vegetables, and fish), multi-time-scale (weekly, monthly, and quarterly) full-chain field sampling was conducted in the Poyang Lake Basin, covering the entire chain from pollution sources to contaminated targets. All collected samples are representative, reliable, and verifiable. The concentrations of nitrogen carriers including nitrate and nitrite, as well as the nitrogen and oxygen isotope abundances in the samples, were determined using national standard (GB) methods and the internationally patented analytical methods developed by our research team. All analytical results are reliable, high-precision, and reproducible. This dataset contains soil nitrate pollutant data from the Poyang Lake Basin during 2020–2021, and is shared under protocol.
