The natural background Mn concentration determined in the negative control treatment was 94 mg kg-I. Total extractable Mn concentrations (in excess of background) in the experimental treatments ranged from 99 to 140% and averaged 111% of nominal. Exchangeable Mn fraction expressed as percent of total concentration increased with increasing soil Mn loads.
Range finding test:
Manganese sulphate monohydrate (MnSO4·H2O) was used to conduct a range finding test. Adult survival and juvenile production decreased significantly at 5,000 mg/kg. There were no juveniles above the 5,000 mg/kg treatment concentration.
Definitive test:
Manganese did not affect (P = 0.168) adult springtail survival at the 1667 mg/kg concentration. Adult survival was significantly reduced (P = 0.0001) at 2444 mg/kg. The bounded NOEC for juvenile production was 1067 mg/kg (P=0.070). The bounded LOEC for juvenile production was 1100 mg/kg (P=0.025). No juveniles were produced in 2444 mg/kg treatment. The
EC20 and EC50 values for Mn for juvenile production were 1209 and 1663 mg/kg, respectively.
