Cr AND Pb CONTAMINATION IN AGRICULTURAL SOIL IN TWO DIFFERENT SEASONS AND THREE DEPTH OF THE SOIL LAYER SAMPLES NEARBY TANNERY WASTE DISPOSAL ZONES AT RANIPET, VELLORE DISTRICT IN THE SOUTHERN INDIA
AbstractThis paper investigates the determination of trace metals named Chromium and Lead set down in the soil as well as in the groundwater due to the tanning industries area of Ranipet town, Vellore city. The tanneries discharge untreated tannery effluents, which get mixed with the soil, water of the Palar river, and underground in this area. The determination of metals was performed for the soil that was collected from the agricultural land adjacent to the Palar River, which bears untreated tannery effluents at pre-monsoon and post-monsoon seasons. The soil samples were collected from three different layers of different depths in these agricultural lands. The first layer is the superficial layer (0 – 10 cm); the second layer is 30 – 40 cm, and the other is 60 – 70 cm below from the surface level. The soil is affected by the untreated effluents through the deposition of heavy metals. The metals might be deposited into the plants and vegetables grown on that agricultural soil, which disturb human health. An extreme amount of chromium was found in all soil samples, especially in the case of superficial layer (0 – 10) part of the soil in pre-monsoon. Chromium and Lead were analyzed by the Atomic adsorption spectroscopy technique (AAS). These metals contamination in the soil is answerable for the support of harmfulness in farming crops and underground water.
