Concentration of Pb, Sn and Fe Metals on Milk Products and Canned Fish in Gorontalo City

Abstract

This study aims to determine the levels of Lead (Pb), Tin (Sn) and Iron (Fe) in milk products and canned fish at the markets around Gorontalo City. A total of 16 samples of infant formula and canned fish were analyzed using Atomic Absorption Spectroscopy (method. The calibration curves showed regression value r = 0.9997 (Sn), r = 0.9965 (Fe), r = 0.9995 (Pb). LOD and LOQ value is Pb=0.09 and 0.11, Sn=1.81 and 2.23, Fe=0.07 and 0.13. The result showed that in infant formula concentration of Pb and Sn were lower than LOD value ppm and concentrations of Fe were obtained 6.91 ppm, 8.09 ppm, 11.07 ppm, 12.27 ppm, 6.79 ppm, 10.27 ppm, 5.96 ppm, 1.57 ppm. In canned fish concentration of Pb and Sn were lower than LOD value and Fe metal of 1-8 samples obtained 12.99 ppm, 8.24 ppm, 11.20 ppm, 15.67 ppm, 7.11 ppm, 11.56 ppm, 19.24 ppm, and 14.99 ppm. Dissensus that the concentration of Fe> Sn> Pb metal in infant formula and canned milk samples. Health Risk Analysis Index (HRI) value in infant formula and canned fish skin samples were <1, so can be assumed these products safe to consume infant formula.
