Sediment core elemental concentration data from pXRF and ICP-MS of sediment from Valley Park, MO

This data contains elemental concentrations from sediment extracted from cores taken in Castlewood State Park floodplain in Valley Park, MO. This data shows that elemental lead (Pb) was in high enough concentrations within this one floodplain that it can be detected using a pXRF. We use this data to show that lead has been deposited from upstream for many years as it exceeds 2 m of deposition in some locations within the floodplain in question. This data serves the foundation of a paper we have published.本数据集收录了采自美国密苏里州谷公园市卡斯尔伍德州立公园河漫滩的沉积物岩芯中的元素浓度信息。数据表明，该河漫滩内的元素铅（Pb）浓度足以通过便携式X射线荧光光谱仪（pXRF）进行检测。我们借助该数据集证实，铅已持续多年从上游沉降至此——在本研究涉及的河漫滩部分区域，铅的沉积厚度超过2米。本数据集是我们已发表学术论文的核心研究基础。
