High levels of cadmium(Cd) (0.0057-0.087 mg/l ) and cobalt(Co) (1.208-2.863 mg/l) above the WHO guideline for drinking water were found at site E (old Jos road bridge T/Wada) in water samples analyzed for both seasons. And also higher levels of cadmium(Cd)(0.055-0.291 mg/l) above the FAO guideline for crops production were recorded in the spinach(Amarantus spp) analyzed in both seasons and levels of copper(Cu)(0.277-5.60 mg/l) above the FAO guideline were recorded in maize(zea mays), okra(Abelmoschus esculent L) and spinach(Amarantus spp) at site A,C and D during the rainy season.Post Graduate Theses
