TABLE 2.

Blood metal level (µg/ml blood) in rats. (A) Lead. (B) Zinc. All the values are expressed as mean ± SEM (n = 5). The statistical significance was considered at p < 0.05, and statistical analysis was performed using one-way ANOVA, followed by Tukey’s test. *p < 0.05, p < 0.05 vs. lead; ^cp < 0.001 vs. ZnO NPs; ^bp < 0.01 vs. Pb + ZnO NPs.
