Green leafy vegetables are the part of daily meal and also important constituent of balanced diet. Heavy metals are naturally occurring element with high atomic weight and density. Various anthropogenic activities produce effluent which builds up runoff water and consequently bleaches into soil adding to heavy metal contents of soil. Green leafy vegetables absorb water through this soil polluted with heavy metals. Former studies highlighted presence of heavy metals in green leafy vegetables. Current study focuses on detection of heavy metal concentration in Spinach from three vegetable markets of Dahisar (D), Mira road (M) and Bhayandar (B). Samples were analysed using atomic absorption spectrometer. Zinc was detected in highest concentration in spinach samples from all locations. Samples from Dahisar showed concentrations of Copper, lead and Zinc, far more than WHO suggested acceptable limit. Chromium was found to be more than WHO limit in spinach sample collected from Dahisar, Mira road and Bhayandar. Remaining metals were found to be in permissible limit. However, persistent consumption of these contaminated leafy vegetable will certainly result in severe health consequences. Therefore, a continuous monitoring and assessment of heavy metal concentration in Spinach plus other green leafy vegetables is required.
