“…In the past years, a number of field observations, laboratory studies and modeling research have been carried out to investigate the abundance and behavior of peroxides in the atmosphere Mao et al, 2010;Liang et al, 2013a;Sarwar et al, 2013;Epstein et al, 2014;Fischer et al, 2015;Khan et al, 2015). Hydrogen peroxide (H 2 O 2 ), hydroxymethyl hydroperoxide (HMHP, HOCH 2 OOH), methyl hydroperoxide (MHP, CH 3 OOH) and peroxyacetic acid (PAA, CH 3 C(O)OOH) are generally determined to be the principal peroxide compounds in the troposphere with their concentrations ranging from pptv (parts per trillion by volume) to ppbv (parts per billion by volume) (Lee et al, 2000;He et al, 2010;Zhang et al, 2010Zhang et al, , 2012.…”
