Diagrams of trace and ultra-trace (micronutrient) element concentrations for the seven plant samples; each element is represented in two concentration ranges: a higher one (left vertical axis and upper part of the chart) and a lower one (right vertical axis and lower part of the chart; the gradient fill suggests that the values are higher than the upper limit of this range): (a) elements with toxic or potentially toxic effects and (b) other elements.
