Which agency is known for setting air quality standards in the United States?

• A. Environmental Protection Agency (EPA)
• B. Food and Drug Administration (FDA)
• C. National Institutes of Health (NIH)
• D. Department of Transportation (DOT)

Answer: (A)

Air quality standards in the United States are set by the Environmental Protection Agency under the Clean Air Act. The EPA establishes National Ambient Air Quality Standards for pollutants like ozone, particulate matter, and other harmful substances, providing benchmarks that protect public health and the environment. States and tribes develop plans to achieve and maintain those standards, with the EPA overseeing and reviewing progress. The other agencies have different missions: the FDA regulates foods, drugs, and cosmetics; the NIH conducts and funds biomedical research; the DOT focuses on transportation safety and mobility, and while it may influence emissions policies in coordination with EPA, it does not set national air quality standards.
