Chemical contamination of food packaging result in blood

From;    Author:
University of Toronto scientists have recently discovered that the junk food packaging and microwave popcorn bags will be transferred to the chemicals in food to go, and was absorbed by the body, causing blood chemical contamination. Perfluorinated carboxylic acids (PFCAs) is a biodegradable chemicals, mainly for the manufacture of cookware and food packaging materials, waterproofing agents, anti-fouling agent. And perfluorooctanoic acid (PFOA) is currently in the body fat around the world Now. The researchers speculate that the human body a source of perfluorinated carboxylic acids may polyfluoroalkyl phosphate (PAPS) related. PAPS fast food packaging materials in microwave popcorn bags or use as an anti-oil. Although researchers are still Can not prove polyfluoroalkyl phosphate is found in the body of PFOA and perfluorinated carboxylic acids the only source, but the research found that metabolites of polyfluoroalkyl phosphate is perfluorooctanoic acid, and the main source of perfluorinated carboxylic acids and, therefore, PFOA found in the body may touch with the people usually related polyfluoroalkyl phosphate.
