中文摘要：
采用室内模拟实验研究了稻草焚烧时15种PAHs排放因子，并对江苏省2000-2005年来源于稻草焚烧产生的BAHs排放量进行了估算．结果表明，稻草焚烧烟气中各PAH的排放因子为11.5-1782．3μg／kg，其中苊（Ace）最大，其次为萘（Nap）、菲（Phe）和芴（Flu），以低分子量PAHs为主；灰烬中PAHs排放因子也以低分子量PAHs为主，但排放总量仅为烟气中的3．2％．根据烟气中排放因子计算。江苏省因稻草焚烧排放的PAHs总量年平均为39．2t左右，超过工业用煤和交通燃油等排放总和．
英文摘要：
Simulated tests were carded out to investigate the emission factors of 15 polycyclic aromatic hydrocarbons （PAHs） from rice straw burning, and on this base, the annual emission of PAHs from rice straw open burning in Jiangsu Province were estimated. Emission factors of PAHs in the smoke were 11.5-1782.3μg/kg, characterized by the predominance of low molecular weight PAHs, which were ranked as Ace〉Nap〉Phe〉Flu, which containing less than 4 aromatic rings. The emission factors in the ashes were also predominated by low molecular weight PAHs, but they were much smaller than those in the smoke. Based on the emission factors in the smoke, the total amount of PAHs emission due to rice straw open burning annually in Jiangsu Province was about 39.2 t in average, exceeding the sum of the PAHs emitted from industry coal combustion and transport petroleum consumption.
