Contaminants in bed sediment from surface waters collected in the Chesapeake Bay Watershed, 2021-24

This data release provides contaminant data from bed sediment collected from small streams between 2021 and 2024 in the Chesapeake Bay Watershed. These data are part of a larger study designed to determine how conservation practices are affecting local stream ecosystem health, which stressors are negatively impacting streams, and which landscape characteristics are associated with better or worse conditions in local streams. Samples were analyzed at RTI Laboratories Incorporated, Livonia, Michigan and The U.S. Geological Survey, Florence Bascom Geoscience Center, Wetland Ecosystem Ecology and Biogeochemistry Lab, Reston, Virginia. Exact site location information for these sites is not available as a result of privacy concerns.

本数据集发布了2021至2024年间于切萨皮克湾流域（Chesapeake Bay Watershed）内小型溪流采集的河床沉积物污染物数据。本数据隶属于一项大型研究，该研究旨在探明保护措施对当地溪流生态系统健康的影响机制、对溪流产生负面影响的环境压力因子，以及与当地溪流环境优劣状况相关的景观特征。样本检测工作分别由密歇根州利沃尼亚市RTI实验室公司（RTI Laboratories Incorporated），以及弗吉尼亚州雷斯顿市美国地质调查局（U.S. Geological Survey）佛罗伦萨·巴斯科姆地球科学中心湿地生态系统生态学与生物地球化学实验室完成。出于隐私保护考量，上述采样点的精确位置信息无法公开。
