Estimation of some heavy elements (Pb, Cd, Ni and Co) in chemical and organic fertilizers and their impact on the safety of the environment and the consumer

Abstract

In this research we are take 11 sample of chemical and organic  fertilizers that available in the local markets specialized in selling places (Khilani Square area) and digestion the samples and configured to check it by atomic absorption spectrophotometer and estimate the heavy elements (Pb, Cd, Ni and Co) where the lead element have the highest value 0.6406 ppm which is animal fertilizer, as well as 0.3915 ppm a Patmos (waste of trees, food, etc.) and it value 0.0890 ppm in a Chemical fertilizers and element cadmium was 0.2824 ppm in highest in Chemical fertilizers were less value 0.0001 ppm in organic fertilizer and the highest value was in  nickel element 0.0457 ppm in Chemical fertilizers and the lowest value was 0.0001 ppm in organic fertilizer and the element cobalt was the highest value 0.0706 ppm in Chemical fertilizers and lowest value 0.0001 ppm in organic fertilizer.
