“…The pPAHs in the "mobile" phase are of particular concern because they are easier to be released into the environment than those interlinked with the macromolecular network (Haenel, 1992;Laumann et al, 2011) during the transportation, storage, and consumption. The emission of pPAHs from the coal combustion includes both the pPAHs released from the coal itself and the pPAHs formed during the combustion process.…”

“…Coal structure can be simplified as two components, including a macromolecular network (insoluble) and a "mobile" phase (soluble), which both contain pPAHs (Haenel, 1992;Laumann et al, 2011). The pPAHs in the "mobile" phase are of particular concern because they are easier to be released into the environment than those interlinked with the macromolecular network (Haenel, 1992;Laumann et al, 2011) during the transportation, storage, and consumption.…”

“…It is well known that coal is a complicated heterogeneous material containing organic maceral and inorganic matters. Meanwhile, many studies had confirmed that PAH formations were strongly dependent on the maceral composition and coal's origin (Laumann et al, 2011). In addition, PAH yields from coal combustion slightly increased from 500°C to 700°C and then exhibited a rapid growth above 700°C.…”

“…Research has shown that coals originating from geologically different coal seams significantly vary in elemental distribution and mineralogy [1][2][3][4][5][6]. Several studies have also investigated variation of mineral matter, and PAHs in coals, either from a single basin or a limited number of coal basins [7][8][9][10][11]. These studies have emphasized the influence of coal rank and coal origin on the elemental distribution.…”
