Study: Cleaner cars helping to reduce LA pollution
(AP) – A newly released study concludes that cars are belching fewer smog-causing chemicals into the Southern California air – even though it still has some of the worst air in the nation.
A federally funded study published online Thursday concludes that the level of some volatile organic compounds – which contribute to ozone pollution – dropped drastically since 1960 and were cut in half between 2002 and 2010 alone. The study says that’s partly because California’s strict air pollution regulations have helped lead to cleaner cars and fuels.
The study was published in a journal of the American Geophysical Union.
