Short summary

Linkages between the chemical composition of PAH-derived SOA and oxidative potential (OP) were investigated under various atmospheric aging processes. Peroxides were found to be an insignificant OP contributor. Oligomerization and heterogeneous ozonolysis may enhance the OP of SOA. Mixing with Cu reduces the OP of PAH-derived SOA. Binding between redox-active Cu(II) and quinone was proved by NMR. Results highlighted the essential role of aerosol chemical composition in its health impact.
