Concentration of inorganic chemistry associated with suspended sediment at Muddy Creek below Paonia Reservoir, U.S. Geological Survey site number 385626107212000.

Dataset includes the analysis results of 49 inorganic chemical elements bound to suspended-sediment particles below Paonia Reservoir during a sediment release in September 2017. Suspended-sediment samples were collected at U.S. Geological Survey (USGS) station number 385626107212000 by following data collection procedures and protocols in Edwards and Glysson (1999). The samples were freeze-dried after collection and then decomposed using a mixture of nitric, hydrofluoric, and perchloric acids. The dried residue after acid digestion was analyzed by atomic absorption spectrometry and inductively coupled plasma-mass spectrometry following procedures and protocols in Taggart (2002). Reference samples of flue gas desulfurization gypsum were also analyzed to test for contamination during the freeze-drying process.

本数据集涵盖2017年9月Paonia水库沉积物释放期间，结合于悬浮沉积物颗粒的49种无机化学元素的分析结果。悬浮沉积物样品采自美国地质调查局（U.S. Geological Survey, USGS）编号为385626107212000的监测站，采样流程遵循Edwards与Glysson（1999）提出的数据收集规范与操作流程。样品采集后经冷冻干燥处理，随后采用硝酸、氢氟酸与高氯酸的混合体系进行酸消解。酸消解后的干燥残渣依据Taggart（2002）的规范流程，分别通过原子吸收光谱法与电感耦合等离子体质谱法完成分析。本研究同步分析了烟气脱硫石膏参考样品，以检测冷冻干燥过程中引入的污染。
