Los contaminantes orgánicos persistentes (COP) son sustancias químicas orgánicas capaces de persistir en el ambiente, transportase a larga distancia, bioacumularse y biomagnificarse en los ecosistemas. Los efectos nocivos de estos compuestos sobre el medio ambiente y la salud de los seres vivos son preocupantes. En particular, los seres humanos pueden entrar en contacto con los COP al consumir alimentos contaminados de origen animal con un alto contenido en grasa. En la República Dominicana estos compuestos se han utilizado y generado ampliamente. Sin embargo, se desconoce cuáles son los niveles de exposición de COP a los que está expuesta la población. Por tanto, este estudio tuvo como objetivo determinar la presencia de 34 COP en cinco principales marcas de leche de vaca de producción nacional. La preparación de las muestras se realizó mediante el método de extracción QuEChERS y la técnica analítica utilizada fue la GC/MS. Los resultados obtenidos indicaron que no hay presencia de los COP evaluados en ninguna de las muestras de leche de vaca, lo cual sugiere que su consumo no representa una amenaza para la salud de los consumidores. Además, este estudio aporta al conocimiento sobre la evaluación de los COP en la República Dominicana.
Persistent organic pollutants (POPs) are organic chemicals capable of persisting in the environment, traveling long distances, bioaccumulate and biomagnify in ecosystems. The harmful effects of these compounds on the environment and the health of living beings are alarming. In particular, humans can be exposed POPs by consuming contaminated fatty animal foods. In the Dominican Republic these compounds have been widely used and generated. However, the degree of POPs exposure to which the population is exposed is unknown. Therefore, this study aimed to determine the presence of 34 POPs in five main brands of nationally produced cow’s milk. The preparation of the samples was carried out using the QuEChERS extraction method and the analytical technique used was GC/MS. The results obtained indicate that there is no presence of the POPs evaluated in any of the cow’s milk samples. These findings suggest that the consumption of this product does not represent a threat to the health of consumers. Furthermore, this study contributes to the knowledge on the evaluation of POPs in the Dominican Republic.
