A Review on the Concentration of the Heavy Metals in Vegetable Samples like Spinach and Tomato Grown Near the Area of Amba Nalla of Amravati City

Abstract

The concentration of heavy metals such as Pd, Cd, Cu and Zn were studied using AAS on vegetable samples as Spinach (leaf ) and Tomato . Trace element as Pd and Cd showed high concentration . The concentration of heavy metal like Pd for Spinach is found to be 5.5 mg/kg-1 and for tomato is 5.5 mg\kg-1more than the maximum permissible limit according to the International organization like FAO and WHO indicating that the Vegetables grown near Amba nalla region in Amravati city have 5.5mg/kg-1 high heavy metal value for Pd .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 posses a major health concern from the research.
