The Solid Phase Distribution and Bioaccessibility of Arsenic, Chromium, and Nickel in Natural Ironstone Soils in the UK

Figure 7

Comparisons of the cumulative mass of As, Cr, and Ni extracted in the CISED identified physicochemical components and its relationship to the bioaccessible fractions. Solid line represents the cumulative mass extracted; the dashed line represents the bioaccessible fraction. Total concentrations of elements are noted on the plot.
