Heavy metal pollution in soil and Water around landfill dumpsite

Abstract

Anthropogenic activity enhances the heavy metal contamination in surrounding environment. This research was designed to measure the metal pollution level from soil and ground water system around land fill dumpsite. The levels of pollution measured from 0 distances to 1200m distance of landfill. The overall study indicated that concentration of heavy metals Arsenic(As), Mercury(Hg), Lead(Pb), Cadmium(Cd), Chromium(Cr), Copper(Cu), Nickel(Ni) and Zinc(Zn) were witnessed in very near to dumpsite also the concentration was decreased when distance increased. The levels of As, Hg, Pb, Cd, Cr, Cu, Ni and Zn in soil were observed every 300m distance (90.75, 90, 77.3, 98.5, 92.3, 58, 95.9 and 94%) respectively. The above level was compared to 1200m distance; the concentration was gradually reduced to (36.8, 0, 51.7, 51.8, 50.4, 56, 51.3 and 46%) separately. Also the concentration of heavy metals in ground water samples at 300 m distance were (100, 96, 90.2, 93.91, 92, 95.5, 100, and 97.3%) the levels reduced to (24.2, 10.3, 30.7, 29.6, 52.5, 49.6, 21.1&57.5%) at 1200m distance. This indicated that the nearest area soil and ground water were highly polluted; however the heavy metals concentration was reduced gradually at far distance. To reduce th toxic compounds from the waste, create awareness for the people to limit the waste from every house. Sanitary landfilling and composting is an excellent and ecofriendly manner of waste mangement

Investigation and Indexing of Eco-Toxic Metals in the Groundwater Around the Kodungaiyur Dumpsite

“…The (5) pharmacokinetics that happens due to the bioaccumulation of these heavy metals is dangerous that activates DNA damage gene activation which is the main cause of carcinogenesis. (6) The potential risk of heavy metal-contaminated drinking water is a threat to the environment due to these metal ions' persistence and non-biogenic nature. This will lead to the bioaccumulation of these metals by plants and animals, which can lead to crucial health problems along the food chain.…”
