Persistence and degradability

Norfolk loamy sand samples (with and without organic matter added) showed increased dsma decomposition relative to soil organic matter. this suggests adaptation of microbial population to metabolize methyl carbon of maa /methanearsonic acid/.

Bioaccumulative potential

Leghorn hens (groups of 5) were fed a diet containing 200 ppm of the herbicide Angar 8100 (active principle disodium methylarsenate) for 30 days ... /until/ slaughter; a similar group was fed the same diet containing 2 g sunflower pectin. Considerable residues /were/ found in the former group, the level in tissue being 0.0250 mg/kg; however, addition of pectin to the diet produced a 30-80% decline, the level in tissue being 0.0047 mg/kg.

Mobility in soil

Type of clay mineral may be responsible for different fixation tendencies ... kaolinite removed much more dsma from soln than did vermiculite. smaller size fractions of augusta silt loam ... absorbed larger percentages of maa /methanearsonic acid/ present in solution.

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. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
