摘要：
The mobility of methyl isothiocyanate (MITC), active metabolite of metam- sodium (MS), was evaluated using undisturbed soil columns. The recovery of MITC in the leachates after two weeks was 14.4 % of the initial applied dose and the total leaching of MITC was estimated at 30 %. One week after application of MS, MITC was recovered in all soil profiles and estimated at 19.8 % of the initial applied amount. The maximum volatilisation of MITC was estimated at 3.75 % after 24 hours and the total volatilisation was about 7 % after three weeks.
