Recent studies have observed enhanced degradation of methyl isothiocyanate (MITC) from repeated fumigation in agricultural soils. Little is known about fumigant degradation in forest and nursery soils. This study was conducted to determine degradation rates of MITC and chloropicrin (CP)

Production and use of methyl bromide, a soil fumigant, are being restricted because of this chemical's deleterious effects on stratospheric ozone concentrations. Several products, some of which are currently used as soil fumigants, are being considered as possible replacements for

The preplant fumigants, metam-sodium, metam-potassium, and dazomet undergo decomposition to the biocide methyl isothiocyanate (MITC) in moist soils. Since MITC vapor can migrate from its site of application, we developed an estimate of health protective concentrations for airborne exposures to

Methyl bromide is being phased out for use on stored commodities, as it is listed as an ozone-depleting substance, and phosphine is the fumigant widely used on grains. However, phosphine resistance occurs worldwide, and phosphine fumigation requires a long exposure
William S Cain et al.
Regulatory toxicology and pharmacology : RTP, 58(2), 173-180 (2010-07-17)
An unpublished laboratory study by Russell and Rush (1996) showed that human subjects sense the presence of methyl isothiocyanate (MITC) via the eyes at concentrations as low as hundreds of ppb in air, with dependence upon duration of exposure. The
