Abstract

Introduction: Soil acts as a major environmental recipient matrix of environmental pollutants and may affect food safety. Objective: Characterizing the polycyclic aromatic hydrocarbons (PAH) and polychlorinated biphenyls (PCB) in soils from different uses and the relation of the PAH in the grass, milk and vegetables.
Methods: The concentration of ·16 PAHs y ·7 PCBs was determined in soils and food by gas chromatography coupled with mass spectrometry.
Results: The concentration of the ·16 PAHs in the soils from urban areas was higher than rural areas. 17 % of the agricultural soils was contaminated (·16 PAHs > 200 µg/kg). The bioavailability results about PAHs in soils were the first reports at a regional level, where the low molecular weight compounds (LMW) were more bioavailable. The studied soils were not contaminated by PCB (·7PCBs > 500 µg/kg). The presence of PAH was informed by the first time in grass, milk and vegetables in Cuba, the LMW compounds being predominant. The PAH concentration in milk and vegetables had a range of 6,86 to 13,49 and 8.00 to 33.00 µg/kg respectively. It is concluded that milk is safe for PAH. However, 100 % of the sample from vegetables had a concentration of the ·4PAH-high molecular weight above 1 ·g/kg, established for other foods by the Europe Union; this compromises their safety.
