This might be due to heavy metal
depositions on the vegetables during transport and marketing
in more polluted urban environment of Varanasi city. The concentrations
of heavy metals in different vegetables at the market sites
varied with the length of exposure and vegetable types. The concentrations
of Cu, Cd and Pb were higher in cauliflower than in palak.
Results suggest that cauliflower having a higher exposed area
of inflorescence has greater capacity to adsorb heavy metals from
the atmosphere.This might be due to heavy metal
