Air Pollution: Regulations and Policies

The Clean Air Act is a comprehensive federal law in the United States designed to protect and improve air quality by regulating air pollution emissions from various sources.

The Convention on Long-Range Transboundary Air Pollution (CLRTAP) is an international agreement that aims to reduce transboundary air pollution in Europe and North America.

Ambient air quality standards are the maximum allowable concentrations of pollutants in the air that are considered safe for human health and the environment.

Electrostatic precipitators are widely used to remove particulate matter from industrial emissions by applying an electrical charge to the particles, causing them to be attracted to and collected on a negatively charged electrode.

Emission control refers to the methods and technologies used to reduce the amount of pollutants released into the air from various sources, such as industrial facilities, vehicles, and power plants.

The Environmental Protection Agency (EPA) is the U.S. government agency responsible for enforcing the Clean Air Act and other environmental regulations.

Environmental impact assessment is the process of evaluating the potential environmental effects of a proposed project or activity before it is implemented.

The Paris Agreement is an international agreement that aims to reduce greenhouse gas emissions and mitigate climate change by setting targets for reducing national emissions.

Pollution prevention refers to the practices and technologies used to reduce or eliminate the generation of pollutants at the source, rather than relying on end-of-pipe control measures.

Selective catalytic reduction (SCR) is a technology used to reduce NOx emissions from vehicles by injecting a reducing agent, such as urea, into the exhaust stream, which reacts with NOx to form nitrogen and water.

Environmental remediation refers to the process of cleaning up contaminated soil, groundwater, or other environmental media to restore them to a safe and usable condition.

The Montreal Protocol is an international agreement that aims to protect the ozone layer by phasing out the production and consumption of ozone-depleting substances, such as chlorofluorocarbons (CFCs).

Waste management refers to the practices and technologies used to manage and reduce waste generation, including collection, transportation, treatment, and disposal of waste materials.

Flue gas desulfurization (FGD) is a technology used to reduce SO2 emissions from power plants by removing sulfur compounds from the flue gas, typically using a scrubber system.

Risk assessment is the process of evaluating the potential risks associated with a particular activity or substance, such as the likelihood and severity of harm to human health or the environment.
