  • Environmental Bioconcentration: BCF values of 23-342 and 42-328 were measured in carp for 1,3,5-trimethylbenzene concentrations of 150 and 15 ug/L, respectively(1). According to a classification scheme(2), BCF values of zero to 30 are low and from 100 to 1,000 are high(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an experimental Koc range of 501-1,445(2-5), indicates that 1,3,5-trimethylbenzene is expected to have low mobility in soil(SRC). Volatilization of 1,3,5-trimethylbenzene from moist soil surfaces is expected to be an important fate process(SRC) given an experimental Henry's Law constant of 8.77X10-3 atm-cu m/mole(6). 1,3,5-Trimethylbenzene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 2.48 mm Hg(SRC), from experimentally-derived coefficients(7). Complete removal of 1,3,5-trimethylbenzene from sterile sandy loam soil samples contaminated with jet fuel was reported within 5 days, probably due to evaporation(8). Biodegradation is expected to occur in soil, and acclimation may increase the rate of biodegradation(SRC). 1,3,5-Trimethylbenzene, present at a concn of 50 mg/kg, degraded considerably after 6 months in the presence of a sewage inoculum during a bioremediation study(9). It was noted that 1,3,5-trimethylbenzene was more resistant to biodegradation than other compounds present(9). The time required for 0.2-1.0 mg/L of 1,3,5-trimethylbenzene to reach less than 1 ug/L was 110 hours in an Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an experimental Koc range of 501-1,445(2-5), indicates that 1,3,5-trimethylbenzene is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected based upon a Henry's Law constant of 8.77X10-3 atm-cu m/mole(6). Using this Henry's Law constant and an estimation method(7), volatilization half-lives for a model river and model lake are 1.2 hours and 4.4 days, respectively(SRC). Residence times (with respect to volatilization) for 1,3,5-trimethylbenzene were calculated as 220 hours for both winter and summer conditions in Narragansett Bay(8). According to a classification scheme(9), BCF values of 23 to 342(10), measured in carp, suggest that bioconcentration in aquatic organisms may be high(SRC). Biodegradation may be an important fate process for this compound in water, and acclimation may increase the rate of biodegradation(SRC). The time required for 0.2-1.0 mg/L of 1,3,5-trimethylbenzene to reach less than 1 ug/L was 110 hours in an adapted groundwater aquifer contaminated with gasoline(11). 1,3,5-Trimethylbenzene was not detected in the effluent of an activated sludge plant that had a r 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), 1,3,5-trimethylbenzene, which has a vapor pressure of 2.48 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1,3,5-trimethylbenzene 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 11 hours(SRC), calculated from its rate constant of 5.75X10-11 cu cm/molecule-sec at 25 °C(1). 1,3,5-Trimethylbenzene also reacts with nitrate radicals in the atmosphere(3); the half-life for this reaction in air is estimated as 10-67 days(SRC). The photooxidation of 1,3,5-trimethylbenzene with nitrogen oxide produces formaldehyde and aliphatic aldehydes at 0.15-0.2 and 0.3-0.4 moles/mole 1,3,5-trimethylbenzene, respectively(5). 1,3,5-Trimethylbenzene does not contain chromophores that absorb wavelengths >290 nm(6) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).
