The Ecological Repercussions of Solid Refuse on Earth Pollution and Microbial Dissemination in Al-Najaf City, Iraq: An Analytical Review

Abstract

The accumulation of solid waste has become one of the most important environmental issues associated with rapid urban growth particularly in developing countries. The city residents are increasing, boundaries of cities are growing, and consumption is increasing, all which contribute to the increasing amount of waste generated in the cities of Iraq. One of the urban areas that is particularly overburdened environmentally is Al-Najaf city, which is a holy city, and has been a vital tourist hub since a large number of pilgrims visit it, and the number of houses and business establishments is still increasing. In this comprehensive review, the impact of solid waste accumulation on soil health is discussed and how it helps in the spread of microbes in metropolitan areas with a special focus on Al-Najaf City. This paper provides a synthesis of existing knowledge by analysing previous geographical and environmental investigations on refuse management, soil degradation, disease carrying microorganisms and ecological difficulties faced in the area. Results show that uncontrolled dumping of refuse results in immediate degradation of soil quality through contaminated runoff, decomposition of the organic material, and toxic pollutants. In addition, the waste piles provide an ideal cover for the growth of harmful bacteria and fungi, especially in over-crowded urban regions with poor local services. Overall, the study highlights the importance of strengthening waste management systems, increasing environmental monitoring, and promoting recycling programs to reduce environmental degradation and improve the health of urban communities.
