Determination of polybrominated diphenyl ethers in shrimp and animal origin oils in Medellín, Colombia

ABSTRACT: Polybrominated diphenyl ethers (PBDEs) are synthetic organic compounds that have been used as brominated flame retardants. They are persistent in the environment, can bioaccumulate in fatty tissues, biomagnify through the food chain, and have adverse health effects on humans and wildlife. The main source of human exposure to PBDEs is the ingestion of contaminated food. Therefore, in this study the concentration of BDE-28, BDE-47, BDE-77, BDE-99, BDE-100, BDE-126, BDE-139, BDE-153, BDE-154, and BDE-183 was determined by gas chromatography coupled to mass spectrometry in shrimps and animal origin oils commercialised and consumed in Medellín, Colombia. All samples of shrimps and animal origin oils analysed had values below 0.0050 ng·g−1 for all the PBDEs studied, with the exception of one shrimp sample in which a concentration of 0.012 ± 0.0056 ng·g−1 of BDE-100 was quantified. The results suggest that shrimps and animal origin oils are not a significant source of exposure to PBDEs of the population of the city. However, it is important to continue analysing PBDEs in foods, including foods other than those evaluated in this investigation, in order to guarantee the innocuity and safety of the food consumed by the population.
