Ambient Air Quality Standards

Air quality standards are designed to protect the population. They ensure that people have clean air to breathe.
National Ambient Air Quality Standards (NAAQS) are regulations established by the Environmental Protection Agency (EPA) under the Clean Air Act to protect public health and the environment from harmful air pollutants. They set limits on the concentration of specific pollutants in the ambient air, including particulate matter, ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. NAAQS are periodically reviewed and updated to reflect new scientific knowledge and ensure adequate protection for vulnerable populations. States are required to develop implementation plans to achieve and maintain these standards.

acid rain is caused by air pollution
epa.gov says, "The Clean Air Act (CAA) is the comprehensive federal law that regulates air emissions from stationary and mobile sources. Among other things, this law authorizes EPA to establish National Ambient Air Quality Standards (NAAQS) to protect public health and public welfare and to regulate emissions of hazardous air pollutants." Does that answer your question?
