What four criteria are used to define hazardous waste what makes heavy metals and synthetic organic compounds particularly hazardous?

What four criteria are used to define hazardous waste? Why are heavy metals and synthetic organic compounds particularly hazardous? organic compounds are resistant to decay, and therefore are persistent in the environment. Many are toxic, absorbable, mutagenic, carcinogenic, or teratogenic.

Which of the following is the criteria to identify hazardous waste?

The four characteristics of hazardous waste are: ignitability • corrosivity • reactivity • toxicity. The regulations explaining these characteristics and the test methods to be used in detecting their presence are found in Part 261, Subpart C.

What are the four methods for treating hazardous waste?

Hazardous waste can be treated by chemical, thermal, biological, and physical methods. Chemical methods include ion exchange, precipitation, oxidation and reduction, and neutralization.

Hazardous-waste characteristics

Hazardous wastes are classified on the basis of their biological, chemical, and physical properties. These properties generate materials that are either toxic, reactive, ignitable, corrosive, infectious, or radioactive. Toxic wastes are poisons, even in very small or trace amounts.
