Polycyclic aromatic hydrocarbons (PAHs) are a class of chemicals that occur naturally in coal, crude oil, and gasoline. They also are produced when coal, oil, gas, wood, garbage, and tobacco are burned. Since these chemicals are ubiquitous in the environment and mainly formed by incomplete anthropogenic organic matter combustion, the general population is exposed to them through food ingestion, air inhalation, and dermal contact. Many studies have reported that food ingestion is the primary pathway or cause of human exposure to PAHs. Milk from grazing ruminant species near anthropogenic PAHs and other sources of pollution may provide significant human exposure not only to PAHs, but other organic pollutants. In this study, a new method for the determination of PAHs in commercial milk was developed. The methodology involved solvent extraction, solid phase extraction, and gas chromatography-mass spectrometry detection (GC-MS). The percent recoveries of the PAHs from spiked samples were determined to assess the applicability of the developed method. The data were then used to determine the presence of PAHs in commercial milk products.
