Preheating (empty heating) is an incorrect use of non-stick pans and is usually warned against on newly purchased non-stick pans�?? labels. This is because non-stick pan coatings may emit toxic volatile organic compounds (VOCs) into the atmosphere when overheated. Surprisingly, the public awareness of this hazard is very low. This may be because most research in this regard was conducted within non-stick pan manufactories or Environmental Working Groups. Few researches were published in peer-reviewed journals. The purpose of this study is to develop a convenient method to collect and analyze VOCs emitted from heating pans in a real life simulation setting which in the future can be adopted in field research. It was hypothesized that heating a non-stick pan with water for 5 minutes will emit less potentially toxic fumes than heating empty. A Solid Phase Micro-extraction (SPME) fiber was used to collect the emitted VOCs and was then desorbed into a Gas Chromatograph-Mass Spectrometer to analyze its components. Three pans of the same model were tested forming 3 trials. The average relative peak areas of one potentially toxic VOC detected, benzoic acid was 10, 570, 370 (84.7 ng) when heating with water compared to 18, 658, 261 (139.3 ng) when heating without water, a 64% increase when heating dry. This confirmed the hypothesis. The progress and results of this study will help design large scale field research in the future which may raise public cautions against preheating non-stick pans.
