職業ばく露

Methyl thiophanate is thiocarbamate ester, used in the synthesis of polymers and in agriculture as pesticides, soil fumigants, and seed disinfectants.

発がん性

Those long-term studies evaluated a variety of toxicity end points including carcinogenicity. Both benomyl and carbendazim were weak carcinogens in some in vivo studies. Rats of the SpDxAug strain were fed 80, 400, and 2000 ppm for 2 years and no evidence for an increase in tumors was seen. In carcinogenicity studies in mice with carbendazim, similar liver tumor finding were found in CD-1 or Swiss strains. On the other hand, no evidence of tumors was seen in a similar study conducted using the NMRKf mouse strain, a strain that has a low incidence of spontaneous tumors.

代謝経路

Thiophanate methyl degradation in water (hydrolytic/ photolysis), soils, plants and animals follows a common pathway that involves the initial conversion into methyl benzimidazol-2-ylcarbamate (carbendazim). Prior to benzimidazole ring formation, at least one side chain undergoes an oxidative desulfuration reaction and partial hydrolysis (even to the substituted aniline). Once formed, carbendazim is degraded primarily via an oxidative mechanism (in animals) or through hydrolysis to 2-aminobenzimidazole (in soils). Possible metabolism pathways of thiophanate methyl are depicted in Scheme 1.

不和合性

Thiocarbamate esters are combustible; dust may form explosive mixture with air. Decomposes163℃Thiocarbamate esters are combustible. They react violently with powerful oxidizers such as calcium hypochlorite. Poisonous gases are generated by the thermal decomposition of thiocarbamate compounds, including carbon disulfide, oxides of sulfur, oxides of nitrogen, hydrogen sulfide, ammonia, and methylamine. Thio and dithio carbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids. Flammable gases are generated by the combination of thiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates are incompatible with acids, peroxides, and acid halides.

廃棄物の処理

In accordance with 40CFR 165 recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
