View larger version (17K): [in a new window]   Fig. 1. Degradation of methyl isothiocyanate (MITC) in Arlington sandy loam at different initial concentrations at 20°C. The points are the means of three measurements (±standard errors) and the curves are first-order fits.

View larger version (19K): [in a new window]   Fig. 2. Correlation between initial concentration and derived degradation rate constant for methyl isothiocyanate (MITC) in Arlington sandy loam at 20°C. The points are mean (±standard errors) degradation rate constants obtained by fitting to respective kinetics.
