本研究的目的是确定铀（U）和其他金属（类）的浓度（As，Cd，Cs，Pb，Mo，Se，Th和V）的8种植物，通常用于药用目的的新墨西哥州的迪内（纳瓦霍）土地。该研究环境是铀矿开采的主要目标，其中仍有500多个未回收的废弃铀矿和结构。这些工厂位于废弃的铀矿和建筑物的3.2公里范围内。收集了植物生物群样品（N = 32）和相应的土壤来源。使用电感耦合等离子体质谱法分析样品。总的来说，研究结果表明，金属（类）S集中最大的土壤>根>地上植物部位，分别。几种药用植物样品被发现超过了世界卫生组织原药材允许的砷和镉水平;然而，使用计算的人类摄入量数据，参考膳食摄入量，推荐的膳食摄入量和可容忍的上限，这些水平没有超过那些既定的食物摄入量或摄入指南。似乎没有一个饮食食物的金属（loid）摄入量上升，仅仅基于八种药用植物检查。对于那些可能对金属（loid）暴露更敏感的人来说，需要通过研究得出的食物摄入建议。需要进一步研究，以确定研究差距，并建议对受采矿影响的社区继续进行监督和监测。
The objective of this study was to determine uranium (U) and other metal(loid) concentrations (As, Cd, Cs, Pb, Mo, Se, Th, and V) in eight species of plants that are commonly used for medicinal purposes on Diné (Navajo) lands in northwestern New Mexico. The study setting was a prime target for U mining, where more than 500 unreclaimed abandoned U mines and structures remain. The plants were located within 3.2 km of abandoned U mines and structures. Plant biota samples (N = 32) and corresponding soil sources were collected. The samples were analyzed using Inductively Coupled Plasma–Mass Spectrometry. In general, the study findings showed that metal(loid)s were concentrated greatest in soil > root > aboveground plant parts, respectively. Several medicinal plant samples were found to exceed the World Health Organization Raw Medicinal Plant Permissible Level for As and Cd; however, using the calculated human intake data, Reference Dietary Intakes, Recommended Dietary Allowances, and tolerable Upper Limits, the levels were not exceeded for those with established food intake or ingestion guidelines. There does not appear to be a dietary food rise of metal(loid) ingestion based solely on the eight medicinal plants examined. Food intake recommendations informed by research are needed for those who may be more sensitive to metal(loid) exposure. Further research is needed to identify research gaps and continued surveillance and monitoring are recommended for mining-impacted communities.
