Which of the following describes a characteristic of toxic waste?

The correct characterization of toxic waste is a waste that is harmful or fatal when ingested. Toxic waste poses significant health risks to humans and the environment due to its chemical properties. This type of waste can cause acute or chronic health issues upon exposure, including poisoning, organ damage, and even death in severe cases.

Understanding the harmful nature of toxic waste is essential for proper handling, treatment, and disposal to ensure safety and environmental protection. In contrast, other options describe conditions that do not align with the definition of toxic waste. For instance, a waste that is safe for disposal does not pose danger, while biodegradable waste refers to materials that can be broken down naturally and are less hazardous. Similarly, a waste that has no environmental impact would not be categorized as toxic waste since its defining characteristic is its potential to harm the environment or human health.
