Fig. 3: Blood and urine Pb concentrations in swine with cola beverage treatment.

Effects of cola beverage on concentrations of Pb in blood (above) and urine (below) samples of swine (a–d) following ingestion of Pb-contaminated Soil 1 (11,600 ± 844 mg kg−1 Pb) and Soil 3 (22,030 ± 817 mg kg−1 Pb), showing significant reduction in Pb levels in swine blood and urine with cola beverage treatment. Data were represented as mean ± S.D. The concentration of Pb in the blood collected from 8−10-week-old Danish Landrace × Yorkshire × Duroc cross-breed swine (n = 4 per group), mean ± S.D, one-way ANOVA (p-value is shown in Table S4) with Bonferroni test. *P < 0.05, **P < 0.01.
