An evaluation of the PAHs emission from small scale incinerators (SSI) in Yen Lac district, Vinh Phuc province, Vietnam was assessed. Twenty-four representative dust samples from the SANKYO incinerators were taken. The concentration levels of PAHs in the samples were determined using gas chromatography coupled with mass spectrometry. The main applied research methods include field observation and sample analysis. The results of the analysis revealed the time trend variation of PAHs concentration in samples. In April, June, September, and November, Σ16PAHs concentrations ranged from 97.83 to 113.0 µg/m3, from 105.32 to 119.04 µg/m3, from 107.25 to 118.73 µg/m3 and from 101.56 to 139.48 µg/m3, respectively. The mean percentages of L–PAHs, M–PAHs and H–PAHs in the analyzed dust samples are 55.7%, 33.8% and 10.5%, respectively. These values can be explained by the PAHs physical chemical properties as well as combustion technology of Sankyo incinerator. The emission factor of 16 PAHs is ranged from 0.0018 to 0.300mg/kg. The results of this study can be applied to estimate the amount of PAH generated when burning domestic waste in rural areas.
