Abstract: 

Background: Contamination of fruit juices with heavy metals presents a risk for human health.
Concentrations of lead, and arsenic in fruit juices of market in Mashhad, Iran, were measured using atomic absorption spectrometry (AAS).
Methods: Fifty varieties of commercial fruit juices (grape, apple, orange, pomegranate, and multifruit) from 5 popular brands (A, B, C, D and E) were purchased from local markets of Mashhad during spring and winter 2016. Five samples of each brand were analyzed by AAS.
Results: The mean concentrations of lead and arsenic were 39.4 and 1.9 ng/mL, with a range of 18.5–54.6 and 1.52-2.35 ng/mL, respectively. Theorange A and multi-fruit A samples had a higher lead level than the others, whilst multi-fruit E contained the lowest. The lowest arsenic content was found in grape B, while the highest was found in multi-fruit C.
Conclusion: Eighty-three percent of the samples had lead levels exceeding the maximum level (30 ng/mL) accepted by theCodex Alimentarius Commission, while arsenic levels were below the maximal permissible value (10 ng/mL). Due to the fact that fruit juices are used by all age groups including infants and children, it is necessary to minimize the health risk from heavy metal contamination in fruit juices. For this reason, the amount of heavy metals contaminants in fruit juice samples should be regularly checked and controlled by the local health authorities.
