摘要

Retene (1-methyl-7-isopropylprienanthrene) is often used as a marker for softwood combustion and for polycycic aromatic hydrocarbon (PAH) source apportionment. The emission factors of retene (EF_(ret)~s) from 11 crop residues, 27 firewood fuels, and 5 coals were measured using traditional rural Chinese stoves. Retene was measured in combustion emissions from all of the residential fuels tested and EF_(RET)~s varied significantly among the fuels due to the differences in fuel properties and combustion conditions. EF_(RET)~s for pine (0.34 ± 0.08 mg/kg) and larch (0.29 ± 0.22 mg/kg) were significantly higher than those of other wood types, including fir and cypress (0.081 ± 0.058 mg/kg). However, EF_(ret)~s for crop residues varied from 0.048 ± 0.008 to 0.37 ± 0.14 mg/kg and were not significantly lower than those for softwood (0.074 ± 0.026 to 0.34 ± 0.08 mg/kg). The EF_(RET)~S for coal were very high and ranged from 2.2 ± 1.S (anthracite briquette) to 187 ±113 mg/kg (raw bituminous chunk), EF_(RET) was positively correlated with Efs of coemitted paniculate matter (EF_(pm)) and phenanthrene (EF_(phe)) for crop residue and coal, but not for wood. In addition, the ratios of EF_(PHE)/EB_(RET) and EF_(pm)/EF_(RET) for coals were much lower than those for crop residues and wood.
