Abstract
Exposure to the chemical endocrine disruptors on human health is of great interest. Bisphenol A (BPA) is a compound mimicing the action of female sex hormones. It is known its toxicity to the reproductive and nervous system. Bisphenol A is a chemical compound widely used in the materials that come into contact with foodstuffs. It is mainly used as a monomer in the manufacture of polycarbonates and epoxy resins. Epoxy resins are most commonly used to make protective coatings of cans for food and beverages. Migration of Bisphenol A may be a result of incomplete flowed polymerization process or after the hydrolysis. The main consumer exposure is through consumption of food and drinks, come into contact with the epoxy resin coated metal packaging. This study aims to determine whether there is a migration of Bisphenol A from metal cans, which are used to store carbonated soft drinks. The study was first for the Bulgarian market and provides information on the potential risk to consumers from the migration of the substance. They were analyzed 150 samples of 5 different types of soft drinks - «Coca-Cola», «Fanta», «Seven Up», «Sprite» and «Tonic». All samples were analyzed by HPLC. According to the Regulation № 10/2011 the specific migration limit for Bisphenol A is 0,6 mg/kg.
