Acetone in the atmosphere: Distribution, sources, and sinks
International audience Acetone (CH3COCH 3) was found to be the dominant nonmethane organic species present in the atmosphere sampled primarily over eastern Canada (0-6 kin, 35ø-65øN) during ABLE3B (July to August 1990). A concentration range of 357 to 2310 ppt (=10-12 v/v) with a mean value of 1140...
