KARAKTERISASI EMISI PAHs HASIL PEMBAKARAN DUPA DALAM RUANG EKSPERIMEN

Abstract

Incense burning, which is the common practice for the majority of Oriental society, had been acknowledged to potentially cause adverse effects due to the production of various air pollutants. Polycylic aromatic hydrocarbons (PAHs) emissions bound to particulate matter from the combustion of several type incense sticks were characterized in the experimental chamber. This study is conducted in Chulabhorn Research Institute, Thailand which is aimed to quantify the emmission level of particle-bound PAHs from selected random incense sticks of three countries (In- donesia, Thailand, and Vietnam). High Performance Liquid Chromatography with Fluorescence Detector (HPLC- FLD) for analysis of PAHs found that the major compound in Indonesian and Thai incenses was fluorenthane Flu (8.2±1.0 and 3.5±0.5 µg/m3 , respectively), while it was CHR (34.5±10.6 µg/m3 ) in Vietnamese incenses. Vietnamese incense emitted the highest total PAHs, with ~5 and ~8 times higher than that of Indonesian and Thai incense, respectively. All incenses emitted BaP in similar level, although Vietnamese incense was still ~1.3 times higher than Indonesian incense and ~1.8 times higher than Thai incense. As for BaP equivalent, Vietnamese incense was ~3.7 and ~7 times higher than that of Indonesian and Thai incense, respectively.
