Polycyclic aromatic hydrocarbons (PAHs) in indoor emission from decorative candles

2011

Abstract This study investigates PAHs indoor emissions from burning decorative candle in an indoor environment because emissions from burning wax in home have rarely been addressed. A total of 12 air samples were collected during the entire burning period of the decorative candles. Particulate and gaseous PAHs emissions were simultaneously measured by passing effluent through a filter (to collect particulate-phase PAHs), a cold trap and ORBO 43 tubes (to capture gaseous-phase PAHs). Analysis involved ultrasound extraction, followed by gas chromatography–mass spectrometry (GC–MS). The measured total PAHs concentration (particulate + aqueous phase + gas phases) for the candles, reported as ma…
