These factors were compared with those of the vegetable irrigated by healthy water. 90 samples were chosen randomly in 3 months i.e. 30 samples per month. Data was analyzed using SPSS. The results showed significant differences for Cr and Ni between two groups, P-value were 0.001 and 0.045 respectively.
