Health safety on plastic materials that come into contact with food and children toys about migration of primary aromatic amines examination in IPH- Skopje in period 01.01.2013 – 31.12.2013

摘要

Humans can be exposed to primary aromatic amines (PAAs) by the usage of a variety of synthetic products which come in contact with food and plastic children toys. PAAs are mainly originated from synthetic azo dyes widely applied as colorants on plastics and also from the use of adhesives based on polyurethanes (PU) in laminated food packing materials. Legislation introduced in the European Union countries limiting the migration level of PAAs into foodstuffs is 0.01 mg/kg. Aim of the study was establishing method for routine examination of PAAs in items made of plastics that come into direct contact with food and plastic toys. udMaterial and Methods: Quantitative determination of sum of PAAs, expressed as aniline on 727 items of which 363 plastic toys, and 364 plastic containers, plastic utensils and plastic items that come in direct contact with food. Was using spectrophotometric method based on diazotization of PAAs and subsequent coupling of the obtained diazonium salts with N-(1-naphthyl) ethylenediamine dihydrochloride.udCalibration was carried out using known amounts of aniline hydrochloride as standard. Detection limit (DL) and quantification limit (QL) evaluated for direct spectrophotometric method amounted to 0,000715 mg/l and 0,002165 mg/l, respectively. Only 6 tested samples were not correct in terms of increased concentration of PAAs in simulant solution. From the faulty samples 4 were toys, and 2 black kitchen sets which coming in contact with food. Conclusion: Requires increased sanitary inspection market, amid frequent occurrence of PAAs in plastic kitchen utensils, especially kitchen utensils in black and children toys made in China.udKeywords: Food Contact Materials (FCM), Toys, Primary Aromatic Amines (PAAs), Migration, Safetyud
