Growing of urban and industrial societies, appearance of metropolis and increasing of municipal soiled wastes as well as many urban difficulties all are serious threats to the environment and public health of any given society. These problems in addition to soil and water resources pollution are needed to be attended seriously. Since plant roots greatly develop in soil surface and with entering the different waste compounds into soil through irrigation water or other pollutants resources, crops growth and their quality is affected, harmful compounds such as heavy metals through crops enter to the life cycle and threat human health as well. The objective of this research is the study of accumulation of heavy metals such as cadmium, lead, and zinc in different depths of soil to maximum 30 Cm. So, three soil treatments including undisturbed (U), disturbed (D), and disturbed with 3 percent of organic matter (O) prepared and leached by 20 mg/l solutions of cadmium, lead, and zinc elements for one month. In the end the concentration of any elements were measured in different depths of soil treatments. The results showed that elements accumulation has a significant difference at 1%, so that cadmium and zinc accumulation were low and high respectively. Also, the accumulation of cadmium and lead were the highest amounts in U treatment and their accumulation were the lowest in O treatment, but zinc accumulation was the highest in D treatment. In addition, the highest amounts of elements were observed at the surface of soil and with increasing the depth it decreased, so that the highest amounts of lead and cadmium accumulation were from the depth of 4 to 6 centimeters in U treatment, but the highest amounts of three elements in D and O treatments were observed from soil surface to the depth of 2 centimeters.
