Abstract
The aim of this study was the quantification of Bisphenol A (BPA) in canned soft drinks, plastic-bottled water and household water tanks from Punjab, India. Samples of five brands of canned soft drinks and plastic-bottled water purchased from local markets. Fifteen samples each of household plastic water tanks and concrete water tank were selected from three different cities (5 from each city) of Punjab, India. Samples were selected randomly. The plastic household water tank samples were collected in the months of December and June to check the effect of temperature on release of BPA in a plastic water tanks. The analysis method consists of microextraction in packed syringe (MEPS) followed by gas chromatography with mass spectrometric (GC-MS) detection. The detection limits and quantitation for BPA were 0.46 pg/mL and 1.52 pg/mL, respectively. Traces of BPA were detected in all canned soft drinks samples. Canned soft drinks and plastic-bottled water samples of five brands were having the BPA concentrations 8.2-14.01 pg/mL and 60-90 pg/mL, respectively. The BPA concentrations in the plastic water tanks were nondetected-12 pg/mL and nondetected-10 pg/mL in concrete water tank.
