A new study raises concerns about the air quality of Alabama's four largest cities.
A report by the Conservation Alabama Foundation found excessive levels of toxic substances in the air in Birmingham, Mobile, Montgomery and Huntsville. Executive director Adam Snyder said Phenix City had the same problem, even though it's smaller.
Snyder said that of 15 chemicals that were studied, data showed levels in the air that were "far beyond" safety limits established by the U.S. Environmental Protection Agency. The foundation wants the state to enact new rules to monitor air quality in neighborhoods.
A spokesman for the Alabama Department of Environmental Management said regulators have a copy of the study and will review it.
