Abstract

Vegetables constitute an important part of the human diet since there containcarbohydrates, proteins, as well as vitamins, minerals and heavy metals. Heavy metals are one of a range of important types of contaminants that can be found onthe surface and in the tissue of fresh vegetables (Bigdeli and Seilsepour, 2008). Anumber of elements, such as lead (Pb), cadmium (Cd), nickel (Ni), cobalt (Co),chromium (Cr), Copper (Cu) and Selenium (Se) (IV) can be harmful to plantsand humans even at quite low concentrations. Soil pollution iscaused by misuse of the soil, such as poor agricultural practices, disposal ofindustrial and urban wastes, etc. The research was conducted in order to see the concentration of heavy metals in leafy vegetables spinach –Spinaci aoleracea, garlic - Allium sativum and onion - Allium cepa. Spinach, garlic and onion seeds were sown on 23rd November 2011; samples for analysis of these plants were taken at different stages –15, 30, 45 and 60 days after sowing.
