Persistence and degradability
AEROBIC: The half-life of demeton-S-methyl in soil was reported as 26 days(1), suggesting that demeton-S may be susceptible to biodegradation in soil(SRC).
Bioaccumulative potential
An estimated BCF of 8 was calculated in fish for demeton-S(SRC), using a water solubility of 2,000 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc value for demeton-S was reported as 70 in an unspecified soil(1). According to a classification scheme(2), this Koc value suggests that demeton-S is expected to have high mobility in soil(SRC).
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.
