What is the purpose of air quality standards?

The purpose of air quality standards is fundamentally to limit the concentration of pollutants in the air. These standards are established to protect public health and the environment by ensuring that air quality remains at safe levels. By regulating the allowable limits of various harmful substances, such as particulate matter, ozone, sulfur dioxide, and nitrogen oxides, these standards help minimize adverse health effects, such as respiratory illnesses, cardiovascular diseases, and other serious health issues caused by poor air quality.

Air quality standards also ensure that air pollution is monitored and controlled, prompting actions to reduce emissions from various sources, including industry, vehicles, and agriculture. This contributes to cleaner air, fostering a healthier living environment for communities and protecting ecosystems affected by air pollution.

While promoting industrial growth, enhancing urban infrastructure, and regulating public transportation can be important for overall economic and urban development, these are not the primary purpose of air quality standards. The focus remains on maintaining air safety and quality for the well-being of the population and the environment.
