Description
In urban environments, a significant portion of atmospheric aerosols are of organic composition with the secondary organic aerosol (SOA) fraction being one of the most important but least understood. This work examines SOA production in a smog chamber using a-pinene and isoprene as biogenic precursors and particle-free ambient urban air as anthropogenic emissions. The observations revealed that the SOA formation is controlled by the components present in the matrix and a-pinene or isoprene affect the reaction processes in such a way that the SOA concentration is either increased or decreased.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
