SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Toxikologische Informationen

Environmental Fate · 3 Einträge

TERRESTRIAL FATE: An estimated Koc of 1.3(1) indicates that octyl potassium phosphate will have very high mobility in soil(2); leaching of this compound is likely as it should be very soluble in water(SRC). Under alkaline soil conditions, hydrolysis of octyl potassium phosphate may be rapid; the rate of hydrolysis in neutral or slightly acidic soil environments should be slower(3). Biodegradation of octyl potassium phosphate in soil may occur; 57-92% biodegradation of a mixture of the mono- and dioctyl phosphate esters was measured over a 4 week time period using an activated sludge inoculum(4). Octyl potassium phosphate is not expected to volatilize from soil surfaces as it is a salt(SRC).

AQUATIC FATE: Hydrolysis of octyl potassium phosphate, particularly in alkaline waters, may be a major fate process for this compound; in neutral or slightly acidic water, octyl potassium phosphate may hydrolyze less rapidly(1). If released to an aquatic environment, octyl potassium phosphate will not bioconcentrate in aquatic organisms based on an estimated BCF of 0(2,3). Octyl potassium phosphate is not expected to adsorb onto particulate matter or sediment in the water column(3). It is likely that octyl potassium phosphate will biodegrade; a biodegradation study using a mixture of mono- and dioctyl potassium phosphate esters measured via BOD 57-92% biodegradation of these compounds(3). Volatilization of octyl potassium phosphate from water surfaces will not occur as this compound has a high estimated water solubility and low estimated vapor pressure(SRC).

ATMOSPHERIC FATE: As a dipotassium salt, octyl potassium phosphate is expected to exist solely as a particulate in the ambient atmosphere. Particulate phase octyl potassium phosphate may be removed physically from the air by wet and dry deposition. (SRC)

Soil Adsorption/MobilityUsing an estimated log Kow of -2.31(1), the Koc for octyl potassium phosphate was estimated as 1.3(2). According to a suggested classification scheme, this Koc value indicates that octyl potassium phosphate will be highly mobile in soil(3).
Artificial Pollution SourcesOctyl potassium phosphate's production and possible use in the manufacture of octyl polyphosphate(1), an anionic surface active agent, may result in its release to the environment through various waste streams.
Environmental Biodegradation57 to 92% biodegradation of a mixture of the mono- and dioctyl potassium phosphate ester was shown via BOD in a 4 week experiment using activated sludge as an inoculum at 30 mg/l and with octyl potassium phosphate present at 100 mg/ml(4).
Environmental Bioconcentration · 1 Eintrag

Based on an estimated log Kow of -2.31(1), the BCF of octyl potassium phosphate is estimated as 0 from a regression-derived equation(2,SRC). This BCF value indicates that bioconcentration of this compound in aquatic organisms is not an important fate process(SRC).

Volatilization from Water/SoilOctyl potassium phosphate is a dipotassium salt which is not expected to volatilize from water surfaces based on its low vapor pressure and high water solubility. (SRC)
Environmental Abiotic Degradation · 1 Eintrag

Hydrolysis of octyldiphenyl phosphate may be a major fate process for this compound particularly as octyl potassium phosphate, as a potassium salt, should be very water soluble(SRC). Hydrolysis of phosphate esters is generally promoted by alkaline conditions. The phosphate ester undergoes second order nucleophilic reactions due to the hydroxide ion involving cleavage of the O-P bond; C-O cleavage is dominant for those compounds which undergo acid and water promoted hydrolyses of esters(1). Mono phosphate esters are more likely to hydrolyze than the equivalent di- or triester(1). Octyl potassium phosphate should exist mainly as the anionic form in the environment based on a roughly estimated pKa of 5(2,SRC).

Environmental Fate/Exposure Summary · 1 Eintrag

Octyl potassium phosphate's production and possible use in the manufacture of octyl polyphosphate, an anionic surface active agent, may result in its release to the environment through various waste streams. If released to the atmosphere, octyl potassium phosphate will exist solely in the particulate phase where it may be removed physically via wet and dry deposition. Octyl potassium phosphate is expected to have very high mobility in soil based on an estimated Koc of 1.3; leaching of octyl potassium phosphate may be possible. Hydrolysis of octyl potassium phosphate may be an important fate process for this compound, particularly under alkaline conditions in either soil or water. Biodegradation of octyl potassium phosphate is possible and may be an important fate process; 57-92% biodegradation of a mono- and dioctyl potassium phosphate mixture was measured via BOD over a 4 week period using an activated sludge inoculum. Volatilization from moist soil surfaces or from water surfaces is unlikely as this compound is a potassium salt. Octyl potassium phosphate will not bioconcentrate in aquatic organisms based on an estimated BCF of 0. (SRC)
