On combustion, forms toxic and corrosive gases.

In laboratory conditions, fenamiphos is stable at pH 5-7.

Flash point data for this compound are not available, however, it is probably combustible.Organothiophosphates, such as FENAMIPHOS, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.

Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

AEROBIC: Fenamiphos is rapidly degraded in soil by microbial processes(SRC). Within 21 days of field application, 74% of the initially applied fenamiphos was transformed to fenamiphos sulfoxide(1). Only trace quantities of fenamiphos were present after this time period (degradation rate of 0.33/day, half-life 2.1 days)(1). 55 Days following application of 14C-fenamiphos to control soil, 5.4% was fenamiphos, 54.6% was fenamiphos sulfoxide, 15.9% was fenamiphos sulfone, 5% was present as other products, 10.6% was present as volatiles and 14C-CO2, and 8.5% was unextractable(1). Degradation half-lives for fenamiphos in four surface soils ranged from 6 to 11 days and 4 to 10 days in the same soils with subsurface collection (60-80 cm)(2). In soils exposed to repeated applications of fenamiphos, observed increased rates of degradation of fenamiphos were 10 to 20 times higher than untreated soil(3). Degradation rates of up to 35 ug/mg microbial carbon per week were observed for fenamiphos after 4 applications while for untreated soil the rate was 2 ug/mg microbial carbon per week(3). Soil which had received annual applications of fenamiphos for 15 yrs was able to degrade fenamiphos in one day verses three days for non-treated soil(4). Fenamiphos mineralization was <9% over 63 days measured in soils which had no prior application of fenamiphos(5). During a 70 day incubation period, 67.2, 27.8, and 9.8% of applied 14C-fenamiphos was mineralized in soil samples collected 2, 3, and 4 yrs after a previous field application, while 10.8, 11.5, and 9.5% of applied 14C-fenamiphos in the respective corresponding control samples was mineralized(6). In a laboratory incubation study, fenamiphos was reported to biodegrade with half-lives of 24 and 72 days for surface and subsurface soils, respectively, while the metabolites of fenamiphos were reported to biodegrade with half-lives of 26 and 119 days for surface and subsurface soils, respectively(7). In a related study, field half-lives for fenamiphos and its metabolites were reported to be 43 and 98 days, respectively(7). In a laboratory study, the half-lives of fenamiphos and its metabolites (total residues) in soils from temperate and tropic/subtropic regions were 72 and 55 days, respectively(8).

Fenamiphos does not bioaccumulate in fish (species non-specified) to any appreciable extent and any residues taken up by fish are quickly depurated when fish are no longer exposed to the residues(1). After 28 days of exposure, the avg measured BCF were 21 and 61 for fillet and whole fish, respectively(1). The maximum BCF measured for fenamiphos residues were 89 for whole fish and 24 for fillet tissue(1). During the 14-day depuration period, more than 95% of the accumulated 14C-fenamiphos residues depurated(1). According to a classification scheme(2), BCFs ranging from 21 to 89(1) suggest that for bioconcentration in aquatic organisms is moderate(SRC). A BCF for fenamiphos of 468 was measured in earthworms(3).

Koc values of fenamiphos in an Arredondo sand (0.80% organic carbon; pH 6.8; 93.8% sand), a Cecil sandy loam (0.90% organic carbon; pH 5.6; 65.8% sand, 19.5% silt, 14.7% clay), and a Webster silty clay loam (3.97% organic carbon; pH 7.3; 18.4% sand, 45.3% silt, 38.3% clay) were 148, 197, and 249, respectively(1). In soil column leaching studies, fenamiphos was most strongly retained in the Webster soil(1). Fenamiphos had a measured Koc value of 190 in a Batcombe soil (3.53% organic matter; pH 6.1)(2). Adsorption of fenamiphos was measured in four surface and subsurface soils from Hawaii; Koc values were 94 to 344 (organic carbon content 1.3-6.22%; pH 5.3-6.7) measured in surface soil and values of 73 to 202 were measured in subsoil (60-80 cm below surface; organic carbon content 0.55-3.19%; pH 5.3-6.8)(3). A Koc of 370 was measured for Molokai silty clay loam (pH 5.8; 1.2% organic carbon)(4). Adsorption of fenamiphos was measured on five European soils; Koc values were 1686 in clay soil (1.3% organic matter), 178.5 in silt loam (3.7% organic matter), 218.5 in loam (3.45 % organic matter), 207.6 in silt (1.55% organic matter), and 935.7 in loamy sand (9.25% organic matter)(5). Fenamiphos had Koc values of 585 (75.0% clay, 3.29% organic carbon), 290 (22.6% clay, 2.39% organic carbon), 210 (17.0% clay, 3.32% organic carbon), 200 (20.3% clay, 1.36% organic carbon) and 1100 (6.0% clay, 4.43% organic carbon) in five European soils(6). According to a classification scheme(7), Koc values of 73 to 148(1,3) have high mobility in soil, Koc values ranging from 190 to 370(1-6) have moderate mobility in soil, and Koc values of 585 to 1686(5-6) have low mobility in soil, suggesting that mobility is very dependent on soil characteristics(SRC).

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.
