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

Product

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.

Contaminated packaging

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.
