उत्तर
Industrial waste is the waste that is produced from industries during the manufacturing process. For example pieces of metals, plastic, chemicals, etc. Industrial wastes are also a major source of environmental pollution. They lead to air and water pollution. The fumes which are generated from industries are highly poisonous and directly affect the respiratory systems of animals, humans and birds. The industrial waste materials are rich in toxic substances and heavy metals such as mercury, lead, copper, and cadmium. Mercury is a toxic substance, which exhibits the phenomenon of biomagnification when it enters the ecosystem via the food chain. Since these chemicals cannot be decomposed, they keep on accumulating at each trophic level. The maximum concentration is accumulated at the top carnivore’s level. This increase in the concentration of pollutants or harmful chemicals with the increase in trophic level is called biological magnification.
