Topic > Environmental Effects of Heavy Metal Pollution

Modern civilization is entirely dependent on a vast collection of metals considering all aspects of our daily lives. There is a long historical connection between metals and human development. It is evident that heavy metal pollution not only has an effect on the production and quality of crops, but correspondingly affects the nature of the atmosphere and water bodies, which leads to endangering the health and life of animals as well as than of man. beings. Almost all materials will definitely produce leachate if water is allowed to saturate through it. The nature of the leachate is mainly determined by the composition and solubility of the waste components. For example, if the composition of the waste changes, due to weathering or biodegradation, this will lead to a change in the quality of the leachate over time. This is especially the case for most municipal waste landfills that include municipal waste. The main routes of human exposure to soil metals are ingestion, inhalation and skin contact. Since soil is the main sink of airborne metals, corresponding measurement of their levels in this medium is useful for establishing abundance trends and their consequences as a result of natural and anthropogenic changes. Environmental pollution caused by heavy metals is a growing global concern (Environmental Resources Management, 2000; De Miguel et al., 2007; Mielke et al., 2010). Global population growth, high living standards, increasing urbanization, together with rapid technological developments, have contributed to an increase in both the quantity and variety of solid waste generated (Zurbrugg, 2002; Chen, 2010). These generated wastes require disposal from time to time....... middle of paper ......ce and the levels of potentially toxic heavy metal elements in the soil environments around the solid waste disposal site in the city of Lichtenburg, in the North Western Province, South Africa. Below are the objectives of the study1. Determine the presence and levels of heavy metals, e.g., Cd, Pb Hg Cu, Fe, Cr in the soil around the selected solid waste disposal.2. Compare the determined concentrations with the recommended concentrations with the aim of assessing environmental risks. 1.7 Location of the study area The study will be conducted in Lichtenburg, North West Province, South Africa, at the two main landfill sites existing in this city. Of the two landfills one is a landfill that has since been closed and is located on the outskirts of the city while the new active landfill is located along the Ventorsdorp–Mafikeng highway in North West Province, South Africa..
