DETECTION OF SOME MIGRATORY CHEMICAL COMPOUNDS FROM NATURAL DRINKING WATER BOTTLES

Abstract

The present study was carried out to determine the migrated compounds from polyethylene terephthalate (PET) to bottled drinking water (BDW) samples of different volumes (0.6, 1.5 and 19L) as well as different color (clear and blue) and different material (PET and PC) which availablein retail shops in Egypt comparing to those of drinking water standards. The water samples were analyzed for various parameters. This study was also carried out to evaluate the somatic mutation effect of dibutyl phthalate and dioctyl phthalate on drosophila as well as to study the effect of cytotoxicity on human cell line (colon cancer cell-liver cancer cell). The obtained results could be summarized as follows: Part Ι : 1. Chemical analysis of perform waterʼs packaging material Analysis of different performs used in packaging of bottled drinking water (BDW) indicated the following results: Twelve of heavy metals; Fe, Ni, Cu, Sb, Pb, Mn, As, Cd, Zn, Ti, BPA and total phthalates (TP) were detected in both of PET material either clear or blue one as well as the polycarbonate (PC) material. Most of detected metals were ranged between 0.02-0.06ppm while only two metals Zn and Cd were 0.01ppm or less in three investigated performs. 2. Factors affecting heavy metals concentration 2.1. Effect of storage temperature (25C±2), storage period, size and type of bottle on heavy metals concentration The heavy metals concentration of sample A (PET, clear, 0.6L) stored at 25C±2/ 210 day it could be seen that all of detected heavy metals were statistically differed from 90th day of storage tell the end of storage (210 day). Except Cu and Al metals which had a permissible level of such metals from the begging of storage (at zero day).
