New study finds gasoline stations vent up to 10x more benzene fumes than previously thought

Green Car Congress

A study led by environmental health scientists at Columbia University Mailman School of Public Health examined the release of vapors from gasoline station vent pipes, and found benzene emissions were 10 times higher than estimates used in setback regulations that determine how close schools, playgrounds, and parks can be to the facilities. Gasoline vapors contain a number of toxic chemicals—notably benzene, a carcinogen.
