ABSTRACT
A hazardous substance is a material that may pose a danger to living organisms, materials, structures, or the environment by explosion or re hazards, corrosion, toxicity to organisms, or other detrimental effects. What, then, is a hazardous waste? A simple denition of a hazardous waste is that it is a hazardous substance that has been discarded, abandoned, neglected, released, or designated as a waste material or one that might interact with other substances to be hazardous. The denition of hazardous waste is addressed in greater detail in Section 15.2, but, in a simple sense, it is a material that has been left where it should not be and that could cause harm to living creatures or its surroundings.
