| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1,200(SRC), determined from a structure estimation method(2), indicates that dihydropinene is expected to have low mobility in soil (SRC). Volatilization of dihydropinene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 0.35 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Dihydropinene is expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.2 mm Hg(SRC), determined from a fragment constant method(4). Biodegradation data were not available(SRC, 2008).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1,200(SRC), determined from a structure estimation method(2), indicates that dihydropinene 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 0.35 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 3.4 hr and 4.7 days, respectively(SRC). Dihydropinene is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). According to a classification scheme(5), an estimated BCF of 450(SRC), from an estimated log Kow of 4.4(6) 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). Biodegradation data were not available(SRC, 2008).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), dihydropinene, which has an estimated vapor pressure of 2.19 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase dihydropinene 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 29 hr(SRC), calculated from its rate constant of 1.34X10-11 cu cm/molecule-sec at 25 °C(3). Dihydropinene does not contain chromophores that absorb at wavelengths >290 nm(4) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC). |

| Ökotoxizitätsauszüge | /AQUATIC SPECIES/ Nearly 500 compounds were detected in the tissues of Great Lakes fish as compared to 8 in tissues of hatchery-reared fish. Lethal concentrations for many representative compounds were determined by testing their acute toxicity (48-hr EC50) to Daphnia pulex. However, the population growth and survival of aquatic organisms over longer time intervals are usually affected at concentrations much lower than the EC50 for a specific chemical. To develop a general relationship between acute and chronic concentrations for representative compounds detected in Great Lakes fish full-life-cycle testing /was initiated/ on D. pulex with ... pinane. Growth and fecundity of daphnids was measured in 16-d tests in the laboratory ... Pinane was moderately toxic to D. pulex in acute studies ... Cyclic alkanes, many of which are constituents of crude oil were represented by pinane for which the EC50 was 3.35 mg/L / at which the endpoint was growth and survival/./AQUATIC SPECIES/ To evaluate the hazard of organic compounds detected in Great Lakes fish by gas chromatography/mass spectrometry, ... compounds representative of heterocyclic nitrogen compounds, polycyclic aromatic hydrocarbons, and cyclic alkanes and alkenes /were tested/. Sixty-day bioassays on the effects of nicotine, phenanthrene, pinane, and pinene on the behavior, growth, and survival of rainbow trout fry, Oncorhynchus mykiss, were conducted in a large, constant-flow, temperature-controlled water system. |

| Soil Adsorption/Mobility | Using a structure estimation method based on molecular connectivity indices(1), the Koc of dihydropinene can be estimated to be 1,200(SRC). According to a classification scheme(2), this estimated Koc value suggests that dihydropinene is expected to have low mobility in soil. |

| Natural Pollution Sources | Pinane derivatives occur in wood, the leaves of many plants, algae, and insects. Pinane itself ... does not occur naturally ... formed on the hydrogenation of pinane derivatives |
|---|
| Artificial Pollution Sources | Dihydropinene's production and use as a chemical intermediate for the production of flavor and fragrance chemicals and use in industry for the production of pinane hydroperoxide(1) may result in its release to the environment through various waste streams(SRC). |
|---|
| Environmental Bioconcentration | An estimated BCF of 450 was calculated for dihydropinene(SRC), using an estimated log Kow of 4.35(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). |
|---|
| Volatilization from Water/Soil | The Henry's Law constant for dihydropinene is estimated as 0.35 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that dihydropinene is expected to volatilize rapidly from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 3.4 hrs(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 4.7 days(SRC). Dihydropinene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Dihydropinene is expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.2 mm Hg(SRC), determined from a fragment constant method(3). |
|---|
| Environmental Abiotic Degradation | The rate constant for the vapor-phase reaction of trans-dihydropinene with photochemically-produced hydroxyl radicals has been estimated as 1.34X10-11 cu cm/molecule-sec at 25 °C(1). This corresponds to an atmospheric half-life of about 29 hrs at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). Dihydropinene is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(2). Dihydropinene does not contain chromophores that absorb at wavelengths >290 nm(2) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC). |

| Probable Routes of Human Exposure | Occupational exposure to dihydropinene may occur through inhalation and dermal contact with this compound at workplaces where dihydropinene is produced or used. Use data suggests that the general population may be exposed to dihyropinene via inhalation of and dermal contact with consumer products containing this compound. (SRC) |
