Irrigation with untreated and treated industrial waste water, discharge of wastes from industries and the application of fertilizers and pesticides into the crop fields, have resulted the addition of heavy metals in the vegetables and soil. In the present study the level of manganese in water, soil and vegetable samples in Sonepat, Haryana (India) was analyzed using Atomic Absorption Spectrophotometer. The concentration of manganese in water, soil and vegetables were 0.06-0.502 mg/L,

Manganese concentration in Kundli water sample is found to be more than the maximum permissible limits, whereas the concentration of manganese in all soil samples is much higher than the WHO permissible limits. Manganese concentrations in the vegetable samples were within the maximum allowable limits. Moreover, soil pH is also evaluated and is found to be in the range of 6.92-7.9. As soil pH affects many chemical processes involved for plant growth.
