The EPA studies pollution and other environmental health hazards.

Yes, that is correct. The Environmental Protection Agency (EPA) is an independent agency of the United States federal government. Its primary responsibility is to protect human health and the environment. The EPA conducts studies, research, and assessments to understand and address pollution and other environmental health hazards. This involves monitoring and analyzing air, water, and soil quality, studying the impact of chemicals and pollutants on ecosystems and human populations, and developing regulations and policies to mitigate these hazards.
