Answer» HEY mate Here is ur answer (a) Radioactive wastes are wastes that contain radioactive material. Radioactive wastes are usually by-products of nuclear power generation and other applications ofnuclear fission or nuclear technology, such as research and medicine. Radioactive waste is hazardous to most forms of life and the environment, and is regulated by GOVERNMENT agencies in order to protect human health and the environment. (b) Defunct ships and e-wastes: - Defunctships are dead ships that are no longer in use. Such ships are brokendown for scrap metal in countries such as India and Pakistan. Theseships are a source of various toxicants such as asbestos, lead,mercury etc. Thus, they contribute to solid wastes that are hazardousto health. E-wastes or electronic wastes generally includeelectronic goods such as computers etc. Such wastes are rich inmetals such as copper, iron, silicon, gold etc. These metals arehighly toxic and pose serious health hazards. People of developingcountries are involved in the recycling process of these metals andtherefore, get exposed to toxic SUBSTANCES present in these wastes. (c) MUNICIPAL solid wastes: - Municipal solidwastes are generated from schools, offices, homes, and stores. It isgenerally rich in glass, metal, paper waste, food, RUBBER, leather,and textiles.
