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.
