Which agency is primarily responsible for reducing the risks associated with toxic substances in the environment?

The Environmental Protection Agency (EPA) is established specifically to protect human health and the environment by regulating the introduction of pollutants and toxic substances. Its primary responsibilities include assessing risks, enforcing regulations regarding air and water quality, waste management, and chemical safety, and conducting research to better understand the impacts of toxins on ecosystems and public health.

While other agencies like the Food and Drug Administration (FDA), the National Institute for Occupational Safety and Health (NIOSH), and the Occupational Safety and Health Administration (OSHA) play crucial roles in managing health and safety regarding certain toxic substances, their focus is more specialized. The FDA regulates food safety and pharmaceuticals, NIOSH is primarily concerned with workplace safety and health, and OSHA focuses on ensuring safe working conditions. In contrast, the EPA has a broader mandate that encompasses various environmental risks associated with toxic substances, making it the primary agency responsible for reducing these risks in the general environment.
