Overview
Akther and colleagues measured lead and chromium by atomic absorption in 18 non-canned and 12 canned carbonated soft drinks bought in Chittagong. Lead was detected in about half the drinks, at no more than 0.017 mg/L, below the Codex 0.02 mg/L level the authors cite. The printed issue is dated 2015; the manifest listed 2016.
Key numbers
- Non-canned soft drinks: lead 0.005 to 0.016 mg/L in 8 of 18; highest S-13, 0.016 ± 0.0042 mg/L (Table 1, p. 154).
- Canned soft drinks: lead 0.006 to 0.017 mg/L in 7 of 12; highest S-12, 0.017 ± 0.0005 mg/L (Table 2, p. 155).
- Chromium up to 0.019 mg/L in canned and 0.018 mg/L in non-canned drinks (Tables 1 and 2).
Methods (brief)
Nitric acid digestion and AAS (Analytik Jena ZEEnit 700P). Values are means ± SEM. Lead calibration standards started at 0.40 ppm, far above the sample results, and no detection limit, recovery or reference material is reported.
Evidence Fitness
One sample per brand, no LOD and a calibration range that does not cover the reported lead levels, so low values are uncertain. Drink flavors are not given, so this is general carbonated soft drink evidence, a proxy for diet-cola and lemon-lime-soft-drink, which are not linked. The PDF does not print the DOI. Results are per litre.
