The PAHs inground coffee were analyzed after being extracted using methods such as saponification-liquid-liquid extraction, Soxhletextraction, and solid-liquid extraction. The solid-liquid extraction method showed the greatest repeatability and mostefficient reduction of the matrix effect. GC-tandem MS for the quantification of the 15 PAHs showed better resolution andlower limit of detections (LODs) than GC-MS-selected ion monitoring (SIM) and high performance liquid chromatographywith fluorescence detector. LODs of this method for the ground coffee types were 0.002-0.1µg/kg and limit ofquantifications (LOQs) were 0.006-0.2µg/kg The recoveries ranged from 52.6 to 93.3%. Forty-six commercial types ofground coffee were analyzed to determine their PAHs contamination levels. PAHs concentration ranged from ND to5.988 µg/kg. This study was conducted with toxicity equivalence factors, the U.S. EPA recommendation to identify dietaryrisks for PAHs in different types of coffee. The estimated average daily dose of PAHs was 5.24×10
