Which group of pollutants specifically includes toxic organics?

The group of pollutants known as priority pollutants specifically includes toxic organics. These are substances that have been identified by regulatory agencies, such as the Environmental Protection Agency (EPA), as being particularly harmful to human health and the environment. This list typically encompasses a variety of organic compounds that are known to be toxic, carcinogenic, or otherwise detrimental when found in water bodies. The identification of these pollutants allows for targeted monitoring and regulation to mitigate their harmful effects.

In contrast, heavy metals refer to a different category of pollutants that do not fall under the description of toxic organics, as they consist primarily of elements like lead, mercury, and cadmium. Organic solids pertain to decomposable organic materials rather than harmful organic chemicals. Biomass relates to organic material derived from living organisms and does not specifically include the toxic organics classified as priority pollutants. Thus, identifying priority pollutants as encompassing toxic organics reflects a focus on those substances most critical to environmental health and safety.
