Persistence and degradability
AEROBIC: Bensulide has been shown to be persistent in soil, with over 5 months required to reduce initial concentrations in soil to 75-100% of the amount applied(1). Under high temperatures, infrequent rainfall, and furrow irrigation, the half-life of bensulide activity was 6 months, with no biological activity after 22 months(2). Bensulide persisted in the soil when applied to a depth of 2.5 and 7.5 cm in a furrow-irrigated sandy loam soil(3); however, the compound was not detected at appreciable amounts 12 months following application rates of 4.5 and 9.0 kg/ha(3).
Bioaccumulative potential
An estimated BCF of 340 was calculated for bensulide(SRC), using a log Kow of 4.20(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not altered physically or chemically once released into the environment(SRP).
Mobility in soil
The Koc of bensulide is estimated as 4,600(SRC), using a log Kow of 4.20(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that bensulide is expected to have slight mobility in soil. Bensulide applied to soil was shown to have a pesticide leaching potential, which relates soil half-life, application rate, and Koc, of 54 at pH 7 and 39 at pH 5(4), suggesting moderate and low potential for contaminating groundwater, respectively(5).
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.

Other Information
No specific data on health hazard of this compound were available but many organophosphates are cholinesterase inhibitors (for instance, see ICSC 0172 on Malathion).If the substance is formulated with solvents also consult the ICSCs of these materials.Carrier solvents used in commercial formulations may change physical and toxicological properties.
