Which is a typical characteristic of hazardous waste?

Hazardous waste is characterized by several properties that can pose significant risks to human health and the environment. The selection of 'All of the above' as the answer reflects the multifaceted nature of hazardous waste.

Non-biodegradability is a prevalent characteristic because many hazardous wastes do not decompose through natural processes, leading to long-term environmental contamination. This persistence in the environment can have detrimental effects on ecosystems, as these substances can accumulate over time.

Flammability is another critical aspect. Many hazardous waste materials are flammable, which means they can easily ignite under certain conditions, resulting in fires that can release toxic fumes and cause environmental damage.

Toxicity is one of the most defining features of hazardous waste. Toxic substances can be harmful or fatal to living organisms, either through direct exposure or through the accumulation in the food chain.

By encompassing non-biodegradable, flammable, and toxic characteristics, 'All of the above' accurately portrays the typical profiles of hazardous waste, showcasing the serious hazards they present across various domains, including health, safety, and environmental integrity.
