Volatile organic compound
Volatile organic compounds (VOCs) are organic compounds that have a high vapor pressure at room temperature. High vapor pressure correlates with a low boiling point, which relates to the number of the sample's molecules in the surrounding air, a trait known as volatility.
Thermal oxidizers provide an air pollution abatement option for VOCs from industrial air flows. A thermal oxidizer is an EPA-approved device to treat VOCs.
The handling of petroleum-based fuels is a major source of VOCs.
A pollutant or novel entity is a substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource. These can be both naturally forming or anthropogenic in origin. Pollutants result in environmental pollution or become public health concerns when they reach a concentration high enough to have significant negative impacts.
Surface runoff, also called nonpoint source pollution, from a farm field in Iowa, the United States during a rainstorm. Topsoil, as well as farm fertilizers and other potential pollutants, runoff unprotected farm fields when heavy rains occur.
