MITC

Methyl isothiocyanate. An organosulphur decomposition product of 3,5-dimethyl-1,3,5,2H-tetrahydrothiadizine-2-thione, which is used as a preservative in manufacturing and coating paperboard, and as a pesticide (dazomet) and soil fumigant on tobacco plants. It is colourless, has a low melting temperature and is a potent lachrymator (tearing agent).

A Uganda Ministry of Internal Affairs analytical laboratory conducted toxicology testing using triple liquid chromatography mass spectrometry in the recently calibrated triple quadrupole liquid chromatograph mass spectrometer (2) for traces of metam sodium or methyl isothiocyanate (a metam sodium degradation product) in the blood of nine symptomatic patients.

Keeping in mind the lethal activity of methyl bromide, different combinations of fumigants and non-fumigants were used as alternatives, such as metham-sodium, which is rapidly converted to methyl isothiocyanate while in contact with moist soil (Hague and Gowen, 1987).

Except for methyl isothiocyanate generators (e.g., metam sodium), these fumigants represent most of the soil fumigants registered by the U.S.

Fumigant dosages below maximum label rate control some soilborne pathogens

ITCs are related to compounds found in chemical soil fumigants metham sodium and dazomet, which release methyl isothiocyanate into the soil; this could be a valuable component of a methyl bromide alternatives program (Fahey et al., 2001).

The pesticicle methyl isothiocyanate, a soil fumigant commonly sprayed on crops, has long caused concern about its ultimate health effects in wildlife and people.

Pesticide breakdown - here comes the sun

In the United States only a handful of fumigants are registered, including methyl bromide, 1,3-dichloropropene (1,3-D), chloropicrin, dimethyl disulfide (DMDS), and methyl isothiocyanate (MITC) generating compounds.

The pesticides evaluated include chloropicrin, chlorothalonil, chlorpyrifos, S,S,S-tributyl phosphorotrithioate, diazinon, 1,3-dichloropropene, dichlorvos (naled breakdown product), endosulfan, eptam, methidathion, methyl bromide, methyl isothiocyanate (MITC; metam sodium breakdown product), molinate, propargite, and simazine.

Community exposures to airborne agricultural pesticides in California: ranking of inhalation risks

On May 26,1995, Philip Morris U.S.A.(*) announced a voluntary recall of 36 cigarette product lines (approximately 8 billion cigarettes) because, during production, the company detected unusual tastes and peculiar odors and identified methyl isothiocyanate (MITC) in the cigarette filters.

For example, the actual fumigant action of metam sodium (a probable carcinogen) comes from a reaction product called methyl isothiocyanate, which is not thought to be a carcinogen.
