Short summary
Air pollutants emitted by human activities such as NOx and SO2 can influence the abundance of secondary organic aerosol (SOA) from biogenic volatile organic compounds (VOCs). We found that NOx suppressed new particle formation and SOA mass formation. When both SO2 and NOx are present, the suppressing effect of NOx on SOA mass formation was counteracted by SO2. High NOx changed SOA chemical composition, forming more organic nitrate, because NOx changed radical chemistry during VOC oxidation.
