Children are vulnerable to heavy metal contamination through consumption of candies and chocolates. Considering this representative samples (69) of candies and chocolates based on cocoa, milk and sugar were analyzed for selected heavy metals by means of flame atomic absorption spectrometry. The average concentration of Zn, Pb, Ni, and Cd was found to be 2.52 ± 2.49, 2.0 ± 1.20, 0.84 ± 1.35, and 0.17 ± 0.22 μg/g respectively. Results indicate that cocoa-based candies have higher metal content than milk- or sugar-based candies. The daily dietary intake of metals for children eating candies and chocolates was also calculated, and results indicated highest intake of Pb and Zn followed by Ni, Cd, and Cu. Comparison of the current study results with other studies around the globe shows that the heavy metal content in candies and chocolates is lower in India than reported elsewhere. However, to reduce the further dietary exposure of heavy metals through candies and chocolates, their content should be monitored regularly and particularly for Pb as children are highly susceptible to its toxicity.
儿童通过食用糖果和巧克力易受重金属污染。考虑到这一点，对基于可可、牛奶和糖的69份糖果和巧克力代表性样品，采用火焰原子吸收光谱法分析了选定的重金属。发现锌、铅、镍和镉的平均浓度分别为2.52±2.49、2.0±1.20、0.84±1.35和0.17±0.22μg/g。结果表明，基于可可的糖果比基于牛奶或糖的糖果含有更高的金属含量。还计算了食用糖果和巧克力的儿童的每日金属膳食摄入量，结果表明铅和锌的摄入量最高，其次是镍、镉和铜。将本研究结果与全球其他研究进行比较表明，印度糖果和巧克力中的重金属含量低于其他地方报道的含量。然而，为了减少通过糖果和巧克力进一步摄入重金属，应定期监测其含量，特别是铅，因为儿童对其毒性高度敏感。
