Health impacts include exposure to toxic chemicals through air, water and soil media; exposure to infection and biological contaminants; stress related to odor, noise, pests and visual amenity; risk of fires, explosions, and subsidence; and spills, accidents and transport emissions. The occupational hazards associated with waste handling according to UNEP Report (1996) are: Infections: Skin and blood infections resulting from direct contact with waste, and from infected wounds; Eye and respiratory infections resulting from exposure to infected dust, especially during landfill operations; Different diseases that result from the bites of animals feeding on the Municipal Solid Waste Management 12 waste; and Intestinal infections that are transmitted by flies feeding on the waste; Chronic diseases: Workers at Incineration plants are at risk of chronic respiratory diseases, including cancers resulting from exposure to dust and hazardous compounds; Accidents: Bone and muscle disorders resulting from the handling of heavy containers; infecting wounds resulting from contact with sharp objects; poisoning and chemical burns resulting from contact with small amounts of hazardous chemical waste mixed with general waste; burns and other injuries resulting from occupational accidents at waste disposal sites or from methane gas explosion at landfill sites.
