Three soils of diverse origins and characteristics were treated with
[14C]NBPT at a nominal applied concentration of 9.5 ppm on dry weight
basis (1,509,000 DPM of 14C-NBPT). The treated soils were maintained in
biometer flasks at about 22 °C in darkness. The degree of NBPT
mineralization, determined as 14CO2, was monitored periodically. The
study was terminated after 50% of the applied NBPT was mineralized.
Mineralization of NBPT to CO2 was rapid in all three soils. In Soils 1
and 2, 53 to 55% of the applied dose was converted to 14C02 after 8 days
of incubation. In Soil 3, 52% of the applied dose was mineralized after
16 days. Mineralization of NBPT is, therefore, considered a significant
route of dissipation in soils.
Between 5.5 and 23.5% of the radiocarbon remaining on soils 1, 2 and 3
was extractable at the point of 50% mineralization. For all three soils,
the bound soil 14C-residues accounted for 40% of the applied dose. NBPT
readily forms bound residues in soil.
Recovery of applied radiocarbon averaged 91.8 ± 1.9% of the applied
dose. No significant losses of radioactivity occurred during the study.
No loss of microbial viability occurred after application of NBPT.
