“…Oxidation products of 1,3,5-TMB were investigated in a number of studies (e.g. Huang et al, 2015;Kalberer et al, 2004Kalberer et al, , 2006Paulsen et al, 2005;Healy et al, 2008;Cocker et al, 2001;Metzger et al, 2008;Wyche et al, 2009;Yu et al, 1997). Methylglyoxal was found as one of the most important oxidation product Healy et al, 2008;Cocker et al, 2001;Wyche et al, 2009;Rickard et al, 2010;Kalberer et al, 2004;Yu et al, 1997;Müller et al, 2012;Nishino et al, 2010;Hamilton et al, 2003;Tuazon et al, 1986;Bandow and Washida, 1985;Lim and Turpin, 2015) contributing with a fraction of up to 2 % to the particle mass (Healy et al, 2008;Cocker et al, 2001).…”
