Prevalence of Health Hazards Associated with Solid Waste Disposal-A Case Study of Kolkata, India

摘要

Multiple factors like population density with high degree of commercialization and rapid urbanization has resulted in problems of solid waste disposal which produce 120,000 tones of solid waste per day in India (2014) and its detrimental consequences. But separate studies on the health hazards associated with waste disposal in the localities of Kolkata are scanty. The aim of this study is to explore the adverse health effects prevalent in the community associated with the solid waste disposal system in a specific locality (i.e. Garia) of Kolkata. A garbage disposable area of Kolkata was selected in Garia and the nearby households (within 500 m from the waste disposable land) were randomly selected and case study was done by interview on the effect of garbage disposal on the health of the adjacent residents with two self structured questionnaires, taking note of perception and awareness about garbage disposal practices. Their recommendation was also sought for eradication of menace. The study clearly indicates failure of the existing facilities, high volume of waste generation, inadequate collection space, and the presence of open-dump sites which generates serious health risks. Information of various types of waste materials like polythene bags, construction wastes, regular solid wastes from households were obtained. It was observed that the people living in this area have poor health like allergy, asthma, skin irritation and other gastro intestinal diseases. The public perception indicated that most people lack knowledge of the harmful effects of waste heaps including that they are breeding grounds for flies, cockroaches, and mosquitoes, rodents etc which are responsible for transmission of germs and zoonotic infections to the people living nearby. The findings of the study will help the stakeholders to take necessary steps to eradicate the problem and to grow a healthier environment.
