Evaluating the spatial distribution of soil physicochemical characteristics and heavy metal toxicity potential in sediments of Nworie river micro-watershed Imo state, southeastern Nigeria

Understanding soil properties, characteristics and their variation is important for their sustainable utilization and proper management of soil and micro-watershed. Sediments can act as reservoir for heavy metals, thereby they are used to assess the pollution status of the rivers. Therefore, the stu...
