This investigation was done to decide the concentrations, sources and potential risks of metals in media around Ijero area. A total of 80 samples including topsoils, sediments, tailings and whole plants were gathered from this territory while control samples were taken from zone with less human exercises. Samples were pounded, sieved and chemically analyzed utilizing Agilent High Plasma Liquid Chromatography Inductively Coupled Plasma-Mass Spectrometer. Results demonstrated that the mean concentrations of lead (Pb) and zinc (Zn) in soils are 30.61 and 123.71 µg/g individually. In tailings the mean distribution of Pb and Zn are 33.16 and 22.44 µg/g each. Toxic units in all media were less than 4, indicating low effect on the ecosystem. Bivariate correlation, hierarchical cluster and principal component analyses revealed that metals in media from this area originated from mining and mineral processing activities, mixed and geogenic sources. Study revealed that metals in the media pose high degree of contamination and moderate to high ecological hazard. Also, there is high cancer-causing hazard index (HI) (10⁻⁶–10⁻⁴) and non-cancer-causing (HI > 1) dangers which is more articulated in kids than the grown-ups. It is important to introduce measures that will decrease the negative impacts associated with mining in the area.

进行这项调查是为了确定Ijero地区周围介质中金属的浓度，来源和潜在风险。从该地区收集了总共80个样品，包括表土，沉积物，尾矿和整株植物，而对照样品则取自较少人工锻炼的区域。使用安捷伦高等离子液相色谱电感耦合等离子质谱仪对样品进行称重，筛分和化学分析。结果表明，土壤中铅（Pb）和锌（Zn）的平均浓度分别为30.61和123.71 µg / g。在尾矿中，铅和锌的平均分布分别为33.16和22.44 µg / g。所有介质中的毒性单位均小于4，表明对生态系统的影响较小。双变量相关 层次聚类和主成分分析表明，该地区介质中的金属源自采矿和矿物加工活动，混合和地源。研究表明，介质中的金属构成高度污染，并具有中度到高度的生态危害。此外，致癌危险指数（HI）也很高（10^-6 –10 ^-4）和非致癌（HI> 1）危险，在儿童中，这种危险要比成年人大得多。重要的是要采取措施，减少与该地区采矿相关的负面影响。
