Assessment of Contents and Health Risk of Aluminum and Copper through Consumption of Commercial Fruit Juices

This study was carried out for analysis of aluminum (Al) and copper (Cu) contents. Human health risk assessment of these elements in commercial fruit juices were collected from a market basket in Iran.
In the current study, a total of 48 samples of four popular brands of fruit juices were analyzed for levels of Al and Cu after digestion with acids using inductively coupled plasma-optical emission spectrometry (ICP-OES) and health index was obtained.
The results showed that the mean concentrations (mg/L) of Al and Cu in fruit juices samples were 1.24 and 0.03, respectively. Although, the mean levels of Al in samples were higher than maximum permissible limits (MPL), health risk assessment indicated that there is no potential risk to children and adults by consuming the commercial fruit juice.
Since the contents of Al in fruit juice samples with an average of 1.24 ± 0.36 mg/L were relatively higher than the MPL, control of metal-containing pesticides and chemical fertilizers residues in agricultural products and also prohibition of use the package containing a layer of aluminum in production process of the commercial fruit juice is recommended for food safety.
