Effect of Sample Sources on Heavy Metal Concentration Measured in Beta Vulgaris Organs

Figure 4

Transfer of metals to the plant and comparison between the sampling sites. Figure 4(a) presents a scatter plot between the transfer of metals to the plant and the leaves at both sampling sites. Figures 4(b) and 4(c) compare the transfer medians of each metal to the entire plant and the leaves in each sampling place; the comparisons were one-tailed, oriented towards the highest transfer median (Mann–Whitney U). In the three figures, navy blue represents the measurements calculated in Sibaté and pink the Mosquera measurements.
