Study finds longer commutes associated with increased human exposure to TDCIPP, a known carcinogen

Green Car Congress

The paper is published in the journal Environment International. Little is known about the toxicity of these organophosphate esters—TDCIPP is one of them—but they’ve replaced older flame-retardant chemicals that lasted longer in the environment and took longer to metabolize.

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.
