STUDYING OF BISPHENOL A LEVELS IN SOME CANNED FOOD, FEED AND BABY BOTTLES IN EGYPTIAN MARKETS

Bisphenol A (BPA) is an endocrine disrupter which causes negative effects on human health. The aim of the present study is to determine BPA levels leaching of several kinds of canned foods, beverages, baby bottles and feed in local Markets by using gas chromatography-mass spectrum (GC/MS/MS). Furthermore, estimate a relationship between BPA migrations from polycarbonate baby bottles, temperature, and effect of numbers of use. Results showed that in more than 130 different samples taken from Egyptian markets, the highest mean BPA level was in chicken cocktail sausaged (710.59 ppb) which was given highly significant results with regard to all other food samples result, whilst the lowest was for tomato ketchup at (5.75 ppb). BPA levels were ranged between 31.02 and 724.06 for canned meat, 5.57 and 233.78 for vegetables and fruits samples and 30.89 and 312.08 for milk samples. It was found that the levels of BPA ranged between (233.65 to 933.75 ppb) in feed additives. The leaching of BPA from baby bottles to milk was found to be highest contents (123.53 ppb) compare with other baby drinks. The effect of temperature and numbers of use on BPA migration from baby bottles to milk results indicated a positive relationship between them, wheres an increasing of temperatures and numbers of use increased BPA migration levels in milk. The concentration of BPA in milk has reached 1046.79 ppb when baby bottles were used 100 times at 90 degrees C.
