Dissolved Metal and Metalloid Concentrations for Dead Run, Baltimore County, MD, USA

This resource includes stream chemistry for Dead Run, Baltimore County, Maryland. This data set is part of the Urban Critical Zone Cluster in the NSF Critical Zone Collaborative Network. Stream grab samples are collected biweekly and analyzed on an ICPMS for 38 dissolved metals and metalloids. Stream sampling sites are co-located with USGS stream gaging stations 01589315 (DR4), 01589312 (DR5), and 01589330 (DRKR). Data are collected for the purpose of (1) trend analysis as a function of space and time; (2) evaluation of the effects of regional geology, anthropogenic perturbations, and weathering processes on stream chemistry; and (3) comparison with stream chemistry from other sites in the Urban CZ cluster.

本资源囊括了马里兰州巴尔的摩县Dead Run的河流化学数据。该数据集隶属于美国国家科学基金会（NSF）关键带合作网络中的城市关键带集群。河流抓取样本每两周收集一次，并使用电感耦合等离子体质谱仪（ICPMS）对38种溶解金属和类金属进行分析。河流采样点与USGS河流测站01589315（DR4）、01589312（DR5）和01589330（DRKR）位于同一位置。数据收集旨在（1）作为空间和时间函数的趋势分析；（2）评估区域地质、人为干扰和风化过程对河流化学的影响；（3）与城市关键带集群中其他地点的河流化学进行对比。
