Determination of some heavy metal levels in soft drinks on the Ghanaian market using atomic absorption spectrometry method.

摘要: Twenty-three soft drink samples (i.e., four pineapple-based fruit drinks, eight citrus-based juices, one soya-based drink, three cola carbonated apple-based and six cocktail drinks) were randomly purchased from retail outlets in an urban market Accra analyzed for the concentrations of iron, cobalt, cadmium, zinc, lead, copper using flame atomic absorption spectrometry. The mean concentration iron cadmium 0.723 ± 0.448 mg/L 0.032 ± 0.012 mg/L, respectively. cobalt was 0.071 ± 0.049 mg/L, while Zn 0.060 ± 0.097 mg/L. Pb Cu juice 0.178 ± 0.091 mg/L 0.053 ± 0.063 mg/L About 78 % exceeded United States Environmental Protection Agency (USEPA) maximum contaminant level 0.3 mg/L prescribed whereas all USEPA 0.005 mg/L cadmium. 91 % EU lead insoft drinks.
