Assessment of cadmium,chromium, and copper levels in market fruit samples in Meerut,North India

The levels of cadmium (Cd), chromium (Cr), and copper (Cu) were assessed in 24 fruit species in Meerut, North India using atomic absorption spectrometry. Data showed that Cd concentrations in fruits except banana, pomegranate, papaya, orange, and cherry were above the recommended maximum allowable limit of Food and Agriculture Organization (FAO)/World Health Organization (WHO) (0.2 µg/g). Average Cr concentrations in all analyzed fruit samples were also found higher than the safe limit of FAO/WHO (2.3 µg/g). In contrast, fruits viz. banana, lychees, papaya, Indian apple, Asian apple, and tiger nut showed concentration of Cu below the recommended safe limit (40 µg/g). Our study demonstrated that concentration of studied heavy metals in all tested samples varied according to fruit species and respective contaminants. Data suggest that more strict rules/standards need to be applied by National/International regulatory agencies in order to make these important fruit items free from heavy metals contamination and protect the consumer.
