Cadmium, Chromium, and Lead Uptake Associated Health Risk Assessment of Alternanthera sessilis: A Commonly Consumed Green Leafy Vegetable

Table 4

The mean Cr, Cd, and Pb concentrations recorded from leaves of Alternanthera sessilis sampled from non-organic and organic cultivations. Results are presented as mean ± SD. In each row, the mean values with different superscript letters are significantly different from each other (ANOVA, Tukey’s test, , N = 80).
