Hazardous Waste

Hazardous Waste & The environment

Dr. Abhinandan Bhardwaj PhD

The term hazardous waste comprises all toxic chemicals, radioactive materials, and biologic or infectious waste. These materials threaten workers through occupational exposure and the general public in their homes, communities, and general environment. Exposure to these materials can occur near the site of generation, along the path of its transportation, and near their ultimate disposal sites. Most hazardous waste results from industrial processes that yield unwanted byproducts, defective products, and spilled materials. The generation and disposal of hazardous wastes is controlled through a variety of international and national regulations.

The universe of hazardous wastes is large and diverse. Hazardous wastes can be liquids, solids, contained gases, or sludge's. They can be the by-products of manufacturing processes or simply discarded commercial products, like cleaning fluids or pesticides.

Most of hazardous waste in developing countries is dumped illegally in streams and rives and oceans. Management of Hazardous waste and proper disposal is extremely important to prevent its exposure to humans.
