Quarry activities are creating diverse stress on biological resources in the rural areas where most of them are located globally. In this study, the effect of quarry activities on elephant grass (Pennisetum purpureum) leaves and soils around Onigambari Forest Reserve, Oyo State, Nigeria, were investigated. Soil and samples of elephant grass (Pennisetum purpureum) leaves were collected from two different distances from the quarry plant. Samples used as control were collected within the boundary of Cocoa Research Institute of Nigeria (CRIN), Oyo State, Nigeria estate. Samples were analysed using proton-induced X-ray emission, to determine the elements. The physiochemical parameters were also analysed in both soil and leaves samples. The mean concentration of the elements in the soil sample from Site 1 was higher in Mg, Cl, Ca, Ti, Cr, Mn, Fe, Zn and Zr than Site 2 and the control site. While in leaves, similar trend was observed. Cd and Ag were highly enriched.
采石活动正在对全球大多数采石场所在的农村地区的生物资源造成多种压力。在这项研究中，调查了采石活动对尼日利亚奥约州奥尼甘巴里森林保护区周围象草（Pennisetum purpureum）叶片和土壤的影响。从采石场植物不同距离采集了土壤和象草（Pennisetum purpureum）叶片样本。作为对照的样本是在尼日利亚可可研究所（CRIN）奥约州的边界内采集的。使用质子诱导 X 射线发射对样本进行了分析，以确定元素。还对土壤和叶片样本中的理化参数进行了分析。来自地点 1 的土壤样本中元素的平均浓度在 Mg、Cl、Ca、Ti、Cr、Mn、Fe、Zn 和 Zr 方面均高于地点 2 和对照地点。而在叶片中，也观察到了类似的趋势。Cd 和 Ag 高度富集。
