Which organization is NOT involved in environmental regulation?

The Food and Drug Administration (FDA) primarily focuses on protecting public health by regulating food safety, pharmaceuticals, medical devices, and cosmetics. While the FDA does have some responsibilities that overlap with environmental factors—like ensuring that the food supply is safe and that drugs are safe for both human use and environmental impact—it is not chiefly an environmental regulatory agency.

In contrast, the Environmental Protection Agency (EPA) is dedicated to protecting human health and the environment by enforcing regulations based on laws passed by Congress. The Arizona Department of Environmental Quality (AZDEQ) operates similarly on a state level, managing environmental quality in Arizona through regulations and programs. The Occupational Safety and Health Administration (OSHA) oversees workplace safety and health, which often includes aspects of environmental regulation related to worker exposure to hazardous materials. Thus, the FDA’s scope is more aligned with health and safety than direct environmental regulation, making it the correct answer for this question.
