Table 1.

EFs of PM, OC, EC, total parent PAHs, oxy- and nitro-PAHs from residential combustions of coal briquette, coal cake, and wood. Data shown are the range from duplicate measurements. Reported values for PAHs and their derivatives are gas- and particle-phase are combined.

EC, g/kg	0.0040–0.0041	0.022–0.052	0.91–1.6
28 pPAHs, mg/kg	14–16	168–223	182–297
16 pPAHs, mg/kg	13–15	148–210	141–276
4 oPAHs, mg/kg	1.7–2.6	4.7–9.5	7.8–10
9 nPAHs, mg/kg	0.64–0.83	0.16–2.4	0.14–0.55
