Which organization sets the ambient air quality standards related to lead?

The Environmental Protection Agency (EPA) is the correct organization responsible for setting ambient air quality standards, including those related to lead. The EPA establishes these standards under the Clean Air Act, aiming to protect public health and the environment from pollutants in the air, which includes lead as one of the designated criteria pollutants. Lead has significant health impacts, particularly on children, and therefore, strict standards are enforced to minimize lead exposure in the environment.

The other organizations have distinct roles that do not involve the establishment of ambient air quality standards. The Occupational Safety and Health Administration (OSHA) focuses on workplace safety and health regulations, ensuring safe working conditions including exposure limits for various substances; however, its regulations are not aimed at overall air quality in the environment. The Centers for Disease Control and Prevention (CDC) primarily addresses public health and disease control rather than environmental standards. Lastly, the Consumer Product Safety Commission (CPSC) is concerned with product safety regulations and does not regulate air quality or set standards for pollutants in the ambient environment.
