Final answer:
Toxic materials are known for their potential harmfulness to organisms, ability to pollute environments, and resistance to biodegradation. They include hazardous chemicals, persistent organic pollutants, radioactive materials, and heavy metals like lead and mercury. Option 4
Step-by-step explanation:
Characteristics of toxic materials include their potential to be harmful to living organisms, their ability to cause environmental pollution, and the fact that they are not easily biodegradable. Toxic materials can include hazardous chemicals and persistent organic pollutants (POPs), such as DDT, dioxin, and PCBs, which are particularly concerning due to their high levels of toxicity and persistence in the environment.
Another category includes radioactive materials, which pose long-term risks of radioactivity. Additionally, heavy metals like lead, mercury, and arsenic, produced largely by industry and mining, can accumulate in the food chain, leading to various health issues. It’s important to note that the boiling point is not necessarily a characteristic that can be generalized across all toxic substances. Option 4
