Nevertheless, humans have direct contact with these metals either directly or indirectly due to their daily association with the environment. Researchers have discovered several adverse effects that depend on the dosage and nature of the interaction. However, the Nigerian government regulators in the Niger Delta ignore the environmental impact of these toxins because it is assumed that only a tiny amount is released into the environment. This work investigates heavy metals' effects and utilizes the GIS tool to assess the degree of impacts. The findings validated the GIS's usefulness, and dosages discharged contributes to environmental degradation.
