(Data are from Strawn et al. [38])
Average total As, P and Fe content in wetland soil (n = 4) isolates from a mine-contaminated site in Coeur d’Alene River Basin, Idaho. Red masses refer to soil fractions isolated from the soil that are elevated in iron oxides. Gray masses refer to soil fractions isolated from the soil that are depleted in iron oxides. Error bars are standard deviations
