- Environmental Bioconcentration: An estimated BCF of 320 was calculated in fish for beta-pinene(SRC), using a log Kow of 4.16(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not metabolized by the organism(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 4,400(SRC), determined from a log Kow of 4.16(2) and a regression-derived equation(3), indicates that beta-pinene is expected to have slight mobility in soil(SRC). Volatilization of beta-pinene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 0.16 atm-cu m/mole(SRC), using a fragment constant estimation method(4). However, adsorption to soil is expected to attenuate volatilization(SRC). beta-Pinene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 2.93 mm Hg(5). Biodegradation data were not available(SRC, 2008). However, by analogy to alpha-pinene which reached 95% of its theoretical BOD using activated sludge in the Japanese MITI test(6), biodegradation may be an important environmental fate process for beta-pinene in soil(SRC).

- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 4,400(SRC), determined from a log Kow of 4.16(2) and a regression-derived equation(3), indicates that beta-pinene is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 0.16 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 3 hours and 5 days, respectively(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 340 days if adsorption is considered(5). According to a classification scheme(6), an estimated BCF of 320(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is high, provided the compound is not metabolized by the organism(SRC). beta-Pinene is not expected to undergo hydrolysis in the environment due to the lack of function 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), beta-pinene, which has a vapor pressure of 2.93 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase beta-pinene 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 4.9 hours(SRC), calculated from its rate constant of 7.89X10-11 cu cm/molecule-sec at 25 °C(3). The rate constant for the vapor-phase reaction of beta-pinene with ozone has been estimated as 1.2X10-17 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). This corresponds to an atmospheric half-life of about 23 hours at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(4). beta-Pinene does not contain chromophores that absorb at wavelengths >290 nm(5) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).
