DETERMINATION OF ARSENIC, LEAD, CADMIUM AND TIN IN FRUIT JUICES SOLD IN AKWA IBOM STATE CHEMISTRY Project Topics – Complete Project Material


ABSTRACT

The presence of heavy-metals in Rubicon, nature fresh, chivita and fumman premium juice were analyzed using NO3 and HNO3, were study Invo-Vitro in the laboratory using atomic absorption spectrophotometer techniques. The results from the study showed Rubicon contained 0.064mg/kg for cadmium 0.005mg/kg for Tin, 0.082mg/kg for lead and 0.023mg/kg for Arsenic. Nature fresh contained 0.049mg/kg in Cd,<0.001mg/kg in Sn; 0.105mg/kg in Pb and 0.009mg/kg in as. Chivita premium contained 0.036mg/kg in Cd, 0.005mg/kg in Sn, 0.068mg/kg in Pb and 0.018mg/kg in as. It was observed that the highest contaminant was Lead (Pb) in nature fresh (Apple juice) and the least contaminant was Tin (Sn) in nature fresh (Apple juice). To be on a healthy side, apple fruit juice should not be consumed readily to decrease dietary intake of lead and other poisonous metals.
