The concentration of heavy metals such as Cd, Pd, Cu and Zn on vegetable such as Spinach (leaf) and Tomato. Trace element as Pd and Cd showed high concentration. Although some heavy metals such as Cu, Zn, Mn and Fe are essential in plant nutrition, many of them do not play any significant role in the plant physiology. The vegetables cultivated and the exposure to heavy metals continuous and is even increasing. Consequently, elevated levels of heavy metals affect food quality and human health all over the world. The concentration of Cd for the vegetable sample as Spinach was 0.3 mg/kg-1 and Tomato were found to be 0.2mg/kg-1 more than the permissible limit. The concentration of the remaining heavy metals as Cu for Spinach is 0.03 mg/kg-1, tomato is 0.045 mg/kg-1 respectively and Zn for Spinach is 2.0 mg/kg-1and for tomato is 3.8 mg/kg-1respectively were within the permissible limit as compared with the FAO (mg/kg-1 1985 and WHO) Pd and Cd are the most severe contaminants. The high level of Cadmium (Cd) in vegetables especially Spinach and Tomato, are suspected for human carcinogens and many more health risks. Samples selected for the study are highly contaminated with Pd and Cd and possess a major health concern from the research.

Keywords:Spinach leaves, Tomato, Pd and Cd, health effect.
