Toxic heavy metal contamination in locally made plastic food container [ ]


The exposure of human to toxic heavy metal release from plastic container creates a major health hazards. The main objectives of this study was to examine the concentration of toxic heavy metals (Pb, Cu, Ni, Zn, Mn, Cr and Cd) in local made food containers purchased from various districts of U.P,(India), at 252C for 24hrs in different simulating solvents as per BIS, IP, USP and other guidelines by using atomic absorption spectrophotometer(AAS). The results found that leaching of heavy metals occur in all samples and showed the order: Pb(1.9-1.01ppm) in S1, S5, S4 > Cu(1.61-1.01ppm) in S4, S3, S5 > Ni(1.31-1.01ppm) in S3, S5, S2, S4 > Mn(1.01-1.001ppm) in S2, S4, S5 > Zn(1.002ppm) in S2.
