The uptake coefficient (gamma) of glyoxal ranges from (1.2 +/- 0.06) x 10(-2) to 2.5 +/- 0.01) x 10(-3) for 60-93 wt % H2SO4, at 253-273 K. The effective Henry's Law constant (H*) ranges from (98.9 +/- 4.9) x 10(5) to (1.6 +/- 0.1) x 10(5) M atm(-1) for 60-93 wt % at 263-273 K. Both the uptake coefficient and Henry's Law constant increase with decreasing acid coneenttation and temperature. Our results reveal a reaction Mechanism of hydration followed by oligomerization for glyoxal on acidic media, indicating an efficient aqueous reaction of glyoxal on hygroscopic particles leading to secondary organic aerosol formation.</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:000354911000018</style></accession-num><notes><style face="normal" font="default" size="100%">Ci6yvTimes Cited:7Cited References Count:52</style></notes><auth-address><style face="normal" font="default" size="100%">Texas A&amp;M Univ, Dept Chem, College Stn, TX 77843 USATexas A&amp;M Univ, Dept Atmospher Sci, College Stn, TX 77843 USATexas A&amp;M Univ, Ctr Atmospher Chem &amp; Environm, College Stn, TX 77843 USA</style></auth-address></record></records></xml>
