Kinetic and product study of the heterogeneous reactions of NO3 radicals with suspended resmethrin, phenothrin, and fenvalerate particles

► Heterogeneous reactions of three typical pyrethroids with NO3 radicals are studied. ► The effective reaction rate constants and uptake coefficients are measured. ► The reaction products are observed with VUV-ATOFMS and GC-MS. ► Molecular structures of the products and the degradation pathways are proposed.
