Effect of phenanthrene on reproduction. The average (n = 5) number of Folsomia candida juveniles per jar after 28 days exposure to reference, and solvent (acetone) control soil, and soil containing 24.95 mg kg-1, and 45.80 mg kg-1 phenanthrene. The acetone treatment did not significantly affect (t-test) reproduction compared to the reference soil, but both phenanthrene concentrations did significantly effect reproduction indicated by asterisks: **P < 0.01; ***P < 0.001. Error bars indicate standard errors.
