  1. Note: Representative chemicals and their values were adapted and summarized from published studies ([17, 57, 58, 83, 90, 100, 106]). Note: a indicated the detected range dependent on variations in wood types (e.g. red oak, birch, eucalyptus, peat, etc) and combustion conditions (e.g., incomplete versus complete)
