Estudio de la migración del ftalato di (2-etilhexil) ftalate (DEHF) en botellas PET al agua embotellada consumida en la ciudad de Cuenca

Abstract

The quality and safety of food products is conditioned by the behavior of the containers, because the food interacts with the container and the surrounding environment, the migration of phthalates to food, is a toxicological risk to human health, phthalates are endocrine and carcinogenic disruptors; such as di (2-ethylhexyl) phthalate (DEHF), due to its high exposure and toxicity in animals and humans. (Al Saleh et al., 2011). In Ecuador, no processes of good storage practices have been implemented, so the containers are exposed to conditions that favor the release of toxic phthalates, for this reason in this study the migration of the DEHF was investigated in 24 samples of bottled water from the brand with the highest consumption in the city of Cuenca, which is distributed and marketed in three supermarkets, selected according to surveys carried out. The extraction of the sample is liquid-liquid (LLE) and the analytical technique used is Gas Chromatography (GC). In this study, 3 samples showed DEHF migration at concentrations of (0.001850 mg/l, 0.001676 mg/l and 0.001294 mg/l), values that are below the parameter established by the Ecuadorian Technical Regulations NTE INEN 2200: 2017 , NTE INEN 1108 and according to the requirements of the WHO that refers a maximum value of (0.008 mg/l), so it is considered that the analyzed samples of bottled water in PET container, of the brand selected in the supermarkets of The city of Cuenca does not constitute a danger to the consumer.
