systems in areas classified “Serious,” “Severe,” or “Extreme” for nonattainment of the ozone national ambient air quality standard (NAAQS). Gasoline-rich vapors in an empty automobile fuel tank are forced out when liquid gasoline is pumped into the tank. The CAA requires states to implement Stage II gasoline vapor recovery.

However, as required by the Clean Air Act, automobile manufacturers began installing onboard refueling vapor recovery (ORVR) technologies in 1998, making gas stations’ systems increasingly redundant. Since 2006, all new automobiles and light trucks (pickups, vans and SUVs) are equipped with ORVR systems.

lower ozone formation potential of the carbonyl compounds present than DF under the identical operating conditions. In addition, there was an 18.0–35.8% reduction in total carbonyls and a 3.4–100% 100% drop in individual carbonyls in the constant load/varying speed test mode. CFT had 16.5–44.1% —Hao et al. 2014.05.025.

Furthermore, airborne chemicals that originate inside a house don’t stay there: Volatile organic compounds (VOCs) from products such as shampoo, perfume and cleaning solutions eventually escape outside and contribute to ozone and fine particle formation, making up an even greater source of global atmospheric air pollution than cars and trucks do.
