Abstract
Soil pollution is majorly caused by human activities (viz: Agricultural practices, industrial activities and poor waste management) and natural effects such as flooding, acid rain, weathering processes. Soil pollution often cause soil barrenness, offensive odour etc. The resultant effect could impact on soil, air and water quality as well as human that reside or work close to the polluted area over a period of time depending on the physical nature of the pollutant as well as its concentration. This study reviews the impacts of soil pollution on air quality under Nigerian setting. The study found that soil pollutants from waste dumpsite could directly or indirectly cause emission of ammonia, methane, hydrogen sulphide, carbon monoxide, oxide of sulphur and nitrogen, and particulates matters into the atmosphere. Most of the aerosols have adverse effect on human health on exposure. The pollutant gases have been implicated as a major cause of respiratory related impairments.
Highlights
Environmental pollution is one of the major challenges facing humanity in the 21st century
In the Niger Delta region of Nigeria, the impacts of soil pollution resulting from natural effects appear to predominantly cause by acid rain and water flooding
Several options can be used to prevent the effect of soil pollution that could release air borne particulates into the environment
Summary
Environmental pollution is one of the major challenges facing humanity in the 21st century. Industrialization, urbanization and developmental projects are the major cause of environmental pollution which is associated to anthropogenic activities have increased with the last century globally [1,2,3,4]. Soil is one of the major receipt of wastes (solid, liquid and air emission) generated from human activities. Izah, et al reported that oil palm processing affect soil and surface water quality receiving the effluents. The human activities causing air pollution include fossil fuel combustion, transportation activities, industrial processes, and non-industrial fugitive sources. Ohimain and Jenakumo, Angaye, et al Ohimain is with opinion that inadequate and irregular evacuation practices by appropriate government agencies is a contributor factor of poor waste disposal methods [22,23,24] These wastes are a major cause of soil pollution. This study focused on the impacts of soil pollution on air quality under Nigeria setting
