New study suggests reported PAH emissions in oil sands region greatly underestimated

Green Car Congress

Data describing emissions to air compiled from two official sources result in simulated concentrations in air, soil, water, and foliage that tend to fall close to or below the minimum measured concentrations of phenanthrene [PHE], pyrene [PYR], and benzo(a)pyrene [BaP] in the environment. Accounting for evaporative emissions (e.g.,
