Japan is also one of the effected countries by the nuclear bomb during Second World War and it is still effecting the population and its environment. These wastes are dangerous for human beings because they contain sulfites that may harm them. Ozone oxidizes bacteria, organic material, moulds, and other contaminants in water. Water pollution is the contamination of water such that it is unfit for use by humans and dangerous for the animals to live in. Presently, pollution of water resources is a significant problem, as it kills aquatic microorganisms, plants and animals by destroying the entire aquatic ecosystems.
