摘要：

In this study the presence of residual levels of Polycyclic Aromatic Hydrocarbons (PAHs) in milk samples from Calabria was evaluated. A comparative analysis of PAHs concentrations was conducted on raw, pasteurized, UHT semi-skimmed and whole milk. Quantitative determination of PAHs was performed by HPLC using a fluorescence detector and analysis in HPLC-MS was conducted to confirm the presence of these compounds. Residual levels of PAHs were found in all milk samples analyzed, showing higher concentrations in pasteurized and UHT milk than in raw milk samples. The results obtained demonstrate that PAHs presence also in raw milk is dependent from environmental pollution but pasteurization and UHT treatments of milk can influence PAHs formation: the differences found between whole and semi-skimmed samples can be due to different fat content of milk.
