15 coal/stove combinations were tested to evaluate their effects on PAH emissions.
pPAH and oPAH emission factors were 0.129–16.7 and 0.059–0.882 mg/kg, respectively.
Geological maturity of coal can significantly affect emissions of pPAHs and oPAHs.
Chunk-to-briquette transformation of coal can increase the emissions of HMW PAHs.
