Abstract
Styrene levels in 12 commodities were determined. The foods tested were wheat, oats, peanuts, pecans, coffee beans, tomatoes, peaches, strawberries, cinnamon, beef, chicken, and milk. The samples were collected in a manner that avoided contact with styrene or any type of plastic. Analytical measurements were performed using a dynamic heated headspace purge-and-trap extraction technique followed by quantification by selected ion monitoring capillary gas chromatography/mass spectrometry. Method blanks, duplicate samples, and samples fortified with benzene and styrene were used to assess method performance. The limit of detection of the method varied between food types but was generally less than 2 ng/g for styrene. The highest measured concentrations of styrene were found in cinnamon (169-39200 ng/g). Styrene concentrations in beef samples ranged from 5.25 to 7.85 ng/g and in coffee beans from 1.57 to 7.85 ng/g. Wheat, pecans, oats, strawberries, and peaches showed no styrene concentrations greater than 3 ng/g. No detectable styrene was found in tomatoes, milk, or chicken
