The findings, published in the Proceedings of the National Academy of Sciences , demonstrate that phase can be a key regulator of the reactivity of atmospheric SOM particles, and may call for a revision of regional and global climate models. For the environment, ammonia is a very tricky compound. In the atmosphere, the particles of ?-pinene

Contribution of gasoline and diesel exhaust to SOA over 0% to 50% diesel fuel use. The study determined that, depending on a region’s fuel use, diesel exhaust is responsible for 65% to 90% of vehicular-derived SOA, with substantial contributions from aromatic and aliphatic hydrocarbons.
