A Characteristic is any one of the four categories used in defining hazardous waste: ignitability, corrosivity, reactivity, and toxicity.

In the environmental context, a characteristic is a feature or quality of a particular substance or material that distinguishes it from other substances or materials. Characteristics may be physical, chemical, or biological, and they can be used to identify, classify, or understand the properties or behavior of a substance or material in the environment.

Here are a few examples of characteristics in the environmental context:

• Physical characteristics of a substance or material may include its color, shape, size, density, or texture. For example, the physical characteristic of a water sample might include its clarity, pH, or temperature.
• Chemical characteristics of a substance or material may include its composition, reactivity, or toxicity. For example, the chemical characteristic of a soil sample might include its nutrient content, pH, or presence of contaminants
• Biological characteristics of a substance or material may include its effect on living organisms, such as plants or animals. For example, the biological characteristic of a chemical might include its ability to cause birth defects or cancer in animals.
• A characteristic of a wetland ecosystem is its hydrology, which is the study of the movement, distribution, and quality of water. Wetlands typically have saturated soils and standing water, and they play an important role in water purification, flood control, and wildlife habitat.
• Biodiversity, which refers to the variety of living organisms found in a given ecosystem. This includes different species, genetic variations within species, and the diversity of habitats and ecosystem functions. Biodiversity is an important characteristic in an ecosystem as it helps to support ecosystem services that benefit human well-being, such as water purification, pollination, and carbon sequestration.
• Climatic stability, the ability of the environment to remain relatively consistent over time, and its resistance to changes in temperature, precipitation, and other climatic variables. An environment with a stable climate is characterized by fewer and less severe natural disasters, which can be beneficial for human populations and ecosystems.

Understanding the characteristics of substances and materials in the environment is important because it allows us to identify potential risks or impacts on the environment and public health, and to develop strategies for managing or mitigating those risks.

For example, a characteristic of a wetland ecosystem is its hydrology, which is the study of the movement, distribution, and quality of water. Wetlands typically have saturated soils and standing water, and they play an important role in water purification, flood control, and wildlife habitat.

Another example of characteristic in the environment context is biodiversity, which refers to the variety of living organisms found in a given ecosystem. This includes different species, genetic variations within species, and the diversity of habitats and ecosystem functions. Biodiversity is an important characteristic in an ecosystem as it helps to support ecosystem services that benefit human well-being, such as water purification, pollination, and carbon sequestration.

Another characteristic of the environment is climatic stability, the ability of the environment to remain relatively consistent over time, and its resistance to changes in temperature, precipitation, and other climatic variables. An environment with a stable climate is characterized by fewer and less severe natural disasters, which can be beneficial for human populations and ecosystems.
