Spanish to English: Polycyclic aromatic hydrocarbons (PAHs) levels in yerba mate (Ilex paraguariensis) from the Argentinean market General field: Science Detailed field: Chemistry; Chem Sci/Eng
Source text - Spanish Abstract
La presencia de hidrocarburos aromáticos policíclicos (PAHs) en alimentos, se debe a varias causas, como la cercanía a fuentes de contaminación, formación de estos durante el procesamiento producto de la pirólisis de los carbohidratos, aminoácidos, y ácidos grasos, entre otros. La principal vía de incorporación de los PAHs a los rumiantes la constituyen los alimentos contaminados. Se ha evaluado que las vacas llegan a ingerir de 65 a 1000 veces más PAHs que los humanos, lo que indicaría el riesgo potencial de contaminación de los alimentos que éstas producen, como es el caso de la leche. Debido a la alta toxicidad de estos compuestos, los estudios sobre su presencia son importantes. El objetivo de este estudio fue evaluar los niveles de PAHs en 31 muestras de leche en polvo comercializadas durante el año 2012 en Argentina y Brasil. La mayor concentración de Benzopireno (BaP) encontrada, fue de 0.570 µg/Kg de leche, y la mediana fue de 0,0424 µg/Kg de leche. La contaminación de las muestras expresada como la sumatoria de los quince PAHs analizados, vario entre 11.8 y 78.4 µg/Kg de leche. La concentración de las muestras expresada como PAH 4 (Sumatoria de Benzopireno, Criseno, Benzo(a)antraceno y Benzo(b)fluoranteno), estuvo entre 0.02 y 10.16 µg/Kg de leche. El coeficiente de correlación para los grupos PAH 2 (Benzopireno y criseno) y PAH 4 fue de 0.95.
Translation - English Abstract
Occurrence of polycyclic aromatic hydrocarbons (PAHs) in food is attributed to numerous causes such as the proximity to pollution sources, its formation during the processing caused by carbohydrate, amino acid and fatty acid pyrolysis, among others. Tainted food is the main route of PAHS incorporation in ruminants. It has been tested that cows are likely to ingest from 65 to 1000 times more PAHs than humans which would suggest the potential risk of polluted food that these produce, as it is the case of milk. Due to the compounds high toxicity, studies about their occurrence are important.
The aim of this study was to test PAHs levels in 31 powdered milk samples marketed in Argentina and Brazil during 2012. The highest concentration of Benzopyrene (BaP) founded was of 0.570 µg/Kg of milk and the median concentration was of 0.0424 µg/Kg of milk. Samples pollution expressed as the sum of fifteen analysed PAHs varied between 11.8 and 78.4 µg/Kg of milk. Samples pollution expressed as PAH 4 (Benzopyrene, Chrysene, Benzo(a)anthracene and Benzo(b)fluoranthene) was between 0.02 and 10.16 µg/Kg of milk. The correlation coefficient for PAH 2 (Benzopyrene and Chrysene) and PAH 4 groups was of 0.95.
