Hazardous Pollutants
What is a Hazardous Pollutant?
A hazardous pollutant is a pollutant material that can affect living organisms in a hazardous manner.
According to the WHO, health risks arise due to direct contact with toxic materials such as lead, cadmium, and chromium that leach from e-waste or by the inhalation of the toxic fumes, as well as from the accumulation of hazardous pollutants in soil, water, and food.

Hazardous waste
What is Hazardous waste?
Hazardous waste is waste that has substantial or potential threats to public health or the environment.
Hazardous waste is a type of dangerous goods.
They usually have one or more of the following hazardous traits: ignitability, reactivity, corrosivity, toxicity.
Listed hazardous wastes are materials specifically listed by regulatory authorities as hazardous wastes which are from non-specific sources, specific sources, or discarded chemical products.
Hazardous wastes may be found in different physical states such as gaseous, liquids, or solids.
Hazardous waste is a special type of waste because it cannot be disposed of by common means like other by-products of our everyday lives.
Depending on the physical state of the waste, treatment and solidification processes might be required.
