SECTION 10: Stability and reactivity
Reactivity
Decomposes on burning. This produces toxic fumes including phosphorus oxides and sulfur oxides.
Chemical stability
Oxidizable in air /srp: to sulfoxides, sulfoxones and their oxones/.
Possibility of hazardous reactions
Flammable in xylene solution.DISULFOTON is incompatible with the following: Alkalis (NIOSH, 2016). Organothiophosphates, such as DISULFOTON, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Conditions to avoid

Persistence and degradability
When ethylthiometon was added to soil under paddy conditions, there was rapid oxidation to the corresponding sulfoxide and sulfone. In silt loam soil, under paddy conditions, reduction of the sulfoxide to ethylthiometon occurred. At 28 deg C, the half-life of ethylthiometon ... /with/ its five metabolites was about 50 days.
Bioaccumulative potential
The bioconcentration factor (BCF) of disulfoton in carp (Cyrinus carpio) has been measured to be approximately 450(1). According to a classification scheme(2), this BCF value suggests bioconcentration in aquatic organisms is high(SRC).
Mobility in soil
Koc values of 642 and 1104(1), 811(2), 1,500(5), and 1,780(6) have been measured for disulfoton(1) and its Rf value has been determined to be 0.01 using soil thin layer chromatography(3). Koc values in 5 EUROSOILS where as follows: 4,622 - Vertic Cambisol clay loam (1.3% OM, pH 5.1), Sicily, Italy; 1,399 - Rendinza silt loam (3.7% OM, pH 7.4), Pelponnesos, Greece; 1,293 - Dystric Cambisol loam (3.45% OM, pH 5.2), Wales; 2,359 - Orthic Luvizol silt (1.55% OM, pH 6.5), Normandy France; 14,013 - Orthic Podzol loamy sand, Schl.-Holstein (9.25% OM, pH 3.2), Germany(4). According to a classification scheme(7), these Koc values suggest that disulfoton soil mobility is expected to range from low to immobile.
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
