Figure 1

Concentrations of ΣPAE (a), total concentrations of the six priority PAEs (b), percentages of six priority PAEs in ΣPAE (c), organic carbon contents (d), percentages of clay minerals (e), and enzyme activities (f) in bulk soils and soil particle-size fractions in different soil layers. In (a)–(c) and (e,f), thin vertical line represents 10th and 90th percentiles. Box represents 25th and 75th percentiles, and central horizontal line represents mean. In (d), the column filled with oblique grids represents active organic carbon. In the x axis, bulk means bulk soil, F1, F2, F3, F4, and F5 represent soil coarse sand (250–2000 μm), fine sand (53–250 μm), coarse silt (20–53 μm), fine silt (2–20 μm), and clay (<2 μm), respectively. Means followed by the same footnote symbol(s) for each soil layer are not significantly different at p < 0.05.
