Dairy cows /were fed/ cottonseed ration containing maa. the maa had no effect on cows, with very little residue accumulating in tissues or milk. the maa appeared to be poorly absorbed from intestinal tract & was rapidly excreted in urine.
In case of fire in the surroundings, use appropriate extinguishing media.
Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Separated from strong bases and food and feedstuffs. Dry. Store in an area without drain or sewer access.SOLID FORMULATIONS ARE SOMEWHAT HYGROSCOPIC & SHOULD BE STORED IN DRY PLACE.

The substance is mildly irritating to the eyes, skin and respiratory tract. Ingestion could cause gastroenteritis. Medical observation is indicated.
The substance may have effects on the kidneys and liver. This may result in impaired functions. This substance is carcinogenic to humans.
A harmful concentration of airborne particles can be reached quickly when dispersed.
The metabolism of maa to inorganic arsenic is the main mechanism of herbicide degradation... the assoc of herbicidal breakdown with the general microbiological activity suggests that the oxidation of maa /methanearsonic acid/ occurred coincidentally with the metab of soil org matter. on the other hand, both norfolk loamy sand samples (with & without organic matter added) showed an increased dsma /disodium salt of maa/ decomposition relative to soil organic matter. this suggested an adaptation of the microbial population to metabolize the methyl carbon of maa. /investigators/...exam the degradation of msma /monosodium salt of maa/ on 4 soils. they concluded that soil microorganisms appeared to play some role in the decomposition process. a fungus, several actinomycetes, & several bacteria were isolated using soil enrichment techniques. the organisms degraded 3, 13 or 9, & 20% of the msma in 11 days, respectively. however, in the absence of an energy source, microbial metabolism of the organic arsenical was nonexistent. the products of metabolism were carbon dioxide & arsenate. no arsenite could be detected.
In aquatic model ecosystem testing bioaccumulation & distribution of (14)c-methanearsonic acid, bioaccumulation ratios for daphnids, gambusia, algae & crayfish were 5, 127, 34, & 5, respectively. bioaccumulation ratio values declined for crayfish & catfish when removed from (14)c-methanearsonic acid exposure to untreated water. (14)c was found @ higher % rate in residue of exptl organisms than (74)as-arsenate.

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.
