Determination of the content of selected trace elements in Polish commercial fruit juices and health risk assessment

Abstract

AbstractThe objective of the study was to determine the content of cadmium (Cd), lead (Pb), arsenic (As), aluminium (Al), thallium (Tl), antimony (Sb) and uranium (U) in the apple and orange juices and black currant nectar in relation to the kind of packaging. Also, probabilistic risk assessment (non-carcinogenic) was estimated by models including target hazard quotient (THQ and THQ*). Aluminium (Al) was present at the highest concentration in the analysed juices and nectars, with average concentration ranging from 1.34 mg/kg in orange juices (glass) to 4.26 mg/kg in black currant nectar (glass). Fruit juices and nectars kept in tetra pack packaging were characterised by elevated concentrations of Al and Sb, while the products in glass packaging contained significantly higher concentrations of As compared with the products in tetra pack packaging. Although the average concentrations of trace elements were lower than the standard limit, exposure to non-carcinogenic factors was demonstrated.
