Abstract
The level of some trace elements including cadmium, cobalt, copper and iron in water and vegetable samples of cabbage (Brassica oleracea var capitata); lettuce (lactuca sativa L); maize (zea mays); okra (Abelmoschus esculent L ); onion (Alium spp) and spinach(Amarantus spp) along the banks of Galma and Kubanni rivers in zaria were determined during the rainy and dry seasons,(June to August 2005 and January to March 2006 respectively), by Atomic Absorption Spectrometry (AAS). 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.
