- Environmental Bioconcentration: An estimated BCF of 1.3 was calculated for 2-hydroxymethyl-2-nitro-1,3-propanediol(SRC), using an estimated log Kow of -1.66(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). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that 2-hydroxymethyl-2-nitro-1,3-propanediol is expected to have very high mobility in soil(SRC). Volatilization of 2-hydroxymethyl-2-nitro-1,3-propanediol from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 4.8X10-12 atm-cu m/mole(SRC), using a fragment constant estimation method(3). 2-Hydroxymethyl-2-nitro-1,3-propanediol is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 3.2X10-7 mm Hg(SRC), determined from a fragment constant method(4). Biodegradation data were not available(SRC, 2006). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that 2-hydroxymethyl-2-nitro-1,3-propanediol is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 4.8X10-12 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 1.3(SRC), from an estimated log Kow of -1.66(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). 2-Hydroxymethyl-2-nitro-1,3-propanediol has reported hydrolysis half-lives of stable, 3.4 days and 2.4 days at pH values 5, 7 and 9, respectively(8). 2-Hydroxymethyl-2-nitro-1,3-propanediol decomposes to formaldehyde under alkaline conditions and at temperatures above 49 °C(9). Biodegradation data were not available(SRC, 2006). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2-hydroxymethyl-2-nitro-1,3-propanediol, which has an estimated vapor pressure of 3.2X10-7 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase 2-hydroxymethyl-2-nitro-1,3-propanediol is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 33 days(SRC), calculated from its rate constant of 1.9X10-12 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase 2-hydroxymethyl-2-nitro-1,3-propanediol may be removed from the air by wet and dry deposition(SRC). 2-Hydroxymethyl-2-nitro-1,3-propanediol does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).
