10.2 Chemical stabilityVery stable over several yr of shelf life & only slight sensitivity to natural light & extreme temperatures.
10.3 Possibility of hazardous reactionsNonflammable.An amine, organosulfide. Organosulfides are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

AEROBIC: Several soil bacteria and fungi are reported to attack ametryne(1). The methylthio group is known to undergo sulfoxidation by microsomal enzymes in plant and animal systems and the same reactions usually hold true for soil microorganisms(1). Methylthio-s-triazine herbicides are generally more resistant to biodegradation than the corresponding chloro-s-triazines(1). No biodegradation was observed when 200 ppm of ametryne was incubated for a month using a soil suspension inoculum at 30°C(2). When the concn equivalent of 3 kg/ha of ametryne was incubated in a clay-lime soil, 2.8% and 8.6% of the herbicide degraded to CO2 in 51 and 110 days, respectively(2). In another experiment, 10-50% degradation in 10 days occurred in one of four soils, while degradation was either absent or uncertain in the other three soils(3). In a 25-day experiment, CO2 evolution occurred from ametryne-treated sterile soil that had been inoculated with an extract from ametryne enriched soil, but not from uninoculated controls(1). After 60 days incubation, 8.7% and 63.7% of the applied ametryne remained in inoculated Hilo silty clay loam and Molakai silty clay, two Hawaiian soils that are typically used in the cultivation of sugarcane(4). The inoculum was prepared by leaching Molakai soil with ametryne solutions(4). Biodegradation initially involved N-dealkylation. Less than 0.2% of the ametryne degraded to CO2 in this period(4). No significant degradation occurred in autoclaved controls(4). Ametryne has been shown to be susceptible to degradation by Nocardiodes sp.(5).
12.3 Bioaccumulative potentialAn estimated BCF of 19 was calculated in fish for ametryne(SRC), using a log Kow of 2.98(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).
12.4 Mobility in soilThe average Koc reported for ametryne in 32 soils was 388.4(1). Ametryne has a Koc value of 300(2). Mean overall Koc values measured in four Hawaiian soils were 257 for surface soil (0 to 20 cm) and 170 for subsoil (60 to 80 cm); Kocs of 530, 170, 156, and 171 were measured in the surface soil of Torrox (mean % OC 1.30, pH 6.7), Eustrustox (mean OC 1.63%, pH 6.4), Tropohumult (mean OC% 2.88, pH 5.3), and Hydrandept (mean OC% 6.22, pH 5.3); Kocs of 235, 254, 87, and 107 were measured in subsoil of Torrox (mean OC% 0.55, pH 6.8), Eustrustox (mean OC% 0.76, pH 5.7), Tropohumult (mean OC% 1.51, pH 5.3), and Hydrandept (mean OC% 3.19, pH 5.6)(3). Koc values were measured for two Kishon River sediments; Kfar Yehushua was 69.33 (7.1 pH, 30% sand, 30% silt 40% clay 1.63% TOC) and Haifa industrial area was 170.40 (6.8 pH, 30 % sand, 20% silt, 50% clay, 1.25% TOC)(4). Koc values ranged from 102-123 in fresh soils amended with activated sludge, anaerobic digested sludge and compost, and 69-129 in incubated soils with the same amendments(5). According to a classification scheme(6), these Koc values suggest that ametryne is expected to have moderate to high mobility in soil(SRC). Of 38 values sited in literature the mean Kd is 5.69(7).

13.Disposal considerations 13.1 Disposal methods ProductThe 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 packagingContainers 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.
