This work highlights the opposing effects of primary and secondary H2SO4 on both secondary organic aerosol (SOA) formation and constitutes. Our findings revealed that a substantial increase in secondary H2SO4 particles promoted the SOA formation of ethyl methacrylate with increasing SO2 in the absence of seed particles. However, increased primary H2SO4 with seed acidity enhanced ethyl methacrylate uptake but reduced its SOA formation in the presence of seed particles.
This work highlights the opposing effects of primary and secondary H2SO4 on both secondary...
