【 摘 要 】

Fruit juices have numerous micronutrients, some of which are trace metals such as tin, zinc, copper, iron and they also contain other metals with no documented benefits to human health (arsenic and lead). These metals found in fruit juices are contaminants and their levels need to be controlled. Atomic absorption spectrophotometer (AAS) was used to determine the levels of some metals: Arsenic, Tin, Copper, Lead, Zinc and Iron in commercially sold fruit juices in South Eastern Nigeria. The results show that Arsenic and Tin contents in the juice samples were very low, less than 0.001mg/l (<0.001mg/l) while other trace metals ranged between 0.001 and 1.532mg/l; Lead ranged between 0.001 and 0.05mg/l; Copper ranged between 0.015 and 0.22mg/l; Zinc ranged between 0.605 and 1.360mg/l and Iron ranged between 0.755 and 1.532mg/l. This paper calls for tighter regulation and the discussion in the choice of materials for processing plants
