- Description: Abstract: Air pollution has been a menace in recent years posing serious threats to environmental and social wellbeing. One death out of every eight global deaths was linked to polluted air. The review of literature in the existing body of knowledge becomes paramount in order to continue with the research on the subject matter. The study will enable the road map for the assessment of the challenging issues related to atmospheric pollution in developing countries. A total number of thirty-five studies relevant to atmospheric pollution were selected out of the total number of fifty studies. The review of literature looked into details on different views from various scholars about the challenges faced by developing countries on air pollution and appropriate control measures. Discussion was also in the various countries that are on the priority list of industrial technologies for protection and exploitation of developed technologies, as well as the forms of technologies for future air pollution control measures. The findings from the literature review showed that the environmental health risk facing the world now is air pollution. This has resulted in the death of millions of people. It was also mostly mentioned that outdoor air pollution exposure levels have risen significantly in some parts of the world, particularly in countries with large populations’ growth through rapid industrialization, such as China and India. The paper presented the assessment of atmospheric pollution reduction: a challenging issue for developing countries. The evidence in literature signals the need for concerted effort to clean up the air we all breathe to save millions of lives.

Atmospheric dry and wet deposition of sulphur and nitrogen species and assessment of critical loads of acidic deposition exceedance in South Africa

- Description: We tested the hypothesis that acidic atmospheric pollution deposition, originating from the South African central industrial area, poses an environmental threat across a larger region within the dispersal footprint. A network of 37 passive monitoring sites to measure SO2 and NO2 was operated from August 2005 to September 2007. The area extended over the entire northern and eastern interior of South Africa. Monitoring locations were chosen to avoid direct impacts from local sources such as towns, mines and highways. Dry deposition rates of SO2 and NO2 were calculated from the measured concentrations. Concentrations of sulphur and nitrogen species in wet deposition from a previous study were used in conjunction with measured rainfall for the years 2006 and 2007 to estimate the wet deposition over the region. The calculated total (non-organic) acidic deposition formed the basis for an assessment of exceedance of critical loads based on sensitivity of the regional soils. Regional soil sensitivity was determined by combining two major soil attributes available in the World Inventory of Soil Emission Potentials (International Soil Reference and Information Centre). Results indicate that certain parts of the central pollution source area on the South African Highveld have the potential for critical load exceedance, while limited areas downwind show lower levels of exceedance. Areas upwind and remote areas up and downwind, including forested areas of the Drakensberg escarpment, do not show any exceedance of the critical loads.
