Soft drinks are highly consumed in Syria due to their preferable taste, advertisement, and lack of awareness about their harmful effects on the human body. Heavy-metal contamination is one of the top problems associated with the soft drinks industry. In this study, the levels of heavy metals (lead [Pb] and cadmium [Cd]) in carbonated and noncarbonated canned soft drinks in the Syrian market were investigated. The leaching of Pb and Cd in canned drinks was also investigated under different storage conditions.
Soft drink samples were collected from the Damascus market. The samples were prepared using microwave digestion. All samples were analyzed using the developed and validated atomic absorption spectroscopy (AAS) method.
All studied samples at all stages of the study were free of Cd. The mean concentration of Pb ranged between 13.76 and 42.12 ppb. Our results showed that the levels of Cd and Pb were in the allowed limits according to Syrian Specification (1992/47) and the Food and Drug Administration (FDA) limits. There is no leaching of Pb and Cd in all studied samples under different storage conditions over 1 year of study.
The results of this study showed that all samples are following good manufacturing procedure (GMP) and safe to be consumed by costumers.
由于口感较好、广告宣传以及人们对其对人体有害影响缺乏认识，软饮料在叙利亚的消费量很高。重金属污染是软饮料行业面临的首要问题之一。在本研究中，对叙利亚市场上碳酸和非碳酸罐装软饮料中的重金属（铅[Pb]和镉[Cd]）含量进行了调查。还研究了罐装饮料在不同储存条件下铅和镉的溶出情况。
从大马士革市场采集软饮料样品。采用微波消解制备样品。所有样品均使用已开发并验证的原子吸收光谱法（AAS）进行分析。
在研究的所有阶段，所有研究样品均未检测出镉。铅的平均浓度在13.76至42.12 ppb之间。我们的结果表明，根据叙利亚规范（1992/47）和美国食品药品监督管理局（FDA）的限值，镉和铅的含量均在允许范围内。在为期1年的研究中，所有研究样品在不同储存条件下均未出现铅和镉的溶出。
本研究结果表明，所有样品均符合良好生产规范（GMP），消费者饮用安全。
