What is the primary function of air quality standards set by regulatory agencies?

The primary function of air quality standards established by regulatory agencies is to protect public health and the environment. These standards are scientifically-based limits on the amount of specific pollutants that can be present in the air, designed to minimize harmful exposure to detrimental substances such as particulate matter, nitrogen dioxide, and ozone. By adhering to these standards, regulatory agencies aim to reduce the risk of adverse health effects, including respiratory diseases, cardiovascular issues, and other serious health conditions that can arise from poor air quality. Additionally, protecting the environment from pollution helps preserve ecosystems and biodiversity, contributing to the overall health of the planet.

In this context, the other choices do not align with the fundamental purpose of air quality standards. While industrial expansion and energy consumption can contribute to economic growth, they are not the primary concerns of air quality regulations. Similarly, while community development can be a positive outcome of healthy air quality, it is not the main aim of these standards. Instead, the foremost goal remains the safeguarding of health and environmental integrity.
