Which statement reflects the importance of air quality standards?

Air quality standards play a crucial role in protecting public health and the environment by establishing legally enforceable limits on the concentration of pollutants in the air. These standards are set based on scientific research that evaluates the health effects of various pollutants, such as particulate matter, ozone, and sulfur dioxide. By adhering to these standards, governments and regulatory agencies can effectively monitor and control air quality, ensuring that levels of harmful pollutants do not exceed thresholds that could pose risks to human health or the environment.

The legally enforceable aspect of these standards means that businesses and industries have a clear legal obligation to comply with the limits set, which promotes accountability and proactive measures in pollution control. This regulatory framework helps to reduce emissions and encourages practices that contribute to cleaner air, thus benefiting public health and the environment as a whole.
