Table 1 Results of the 56-d earthworm reproductive toxicity test. Data are given in mean ± standard error (n = 20 jars, 5 adult worms added in each jar) followed by a letter indicating significant (if different, p < 0.05) or insignificant difference (if the same, p > 0.05) from the control (ANOVA). The nominal concentrations of TNT and RDX are 50 mg/kg soil and 30 mg/kg soil, respectively.
