- Environmental Bioconcentration: An estimated BCF of 586 was calculated in fish for alpha-amyl cinnamaldehyde(SRC), using a log Kow of 4.70(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 680(SRC), determined from a structure estimation method(2), indicates that alpha-amyl cinnamaldehyde is expected to have low mobility in soil(SRC). Volatilization of alpha-amyl cinnamaldehyde from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 7.8X10-6 atm-cu m/mole(SRC), using a fragment constant estimation method(1). alpha-Amyl cinnamaldehyde is not expected to volatilize from dry soil surfaces based upon an estimated vapor pressure of 0.00431 mm Hg(SRC), determined from a fragment constant method(1); however, alpha-amyl cinnamaldehyde does volatilize in its consumer use as a perfume in soaps and detergents(3). Biodegradation is expected to be an important fate process in soil based on results of various various screening test(SRC). alpha-Amyl cinnamaldehyde, present at 100 mg/L, reached 51% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(4). Using OECD Method 301B (CO2 evolution), alpha-amyl cinnamaldehyde had a 65% degradation in 28 days indicating it was readily biodegradable( Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 680(SRC), determined from a structure estimation method(2), indicates that alpha-amyl cinnamaldehyde 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 7.8X10-6 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 6.8 and 54 days, respectively(SRC). According to a classification scheme(4), an estimated BCF of 586(SRC), from a log Kow of 4.70(5), suggests the potential for bioconcentration in aquatic organisms is high(SRC). alpha-Amyl cinnamaldehyde is stable to hydrolysis in water(5); the aldehyde group has a potential to oxidize to carboxylic acid in water(5). Biodegradation is expected to be an important fate process in water based on results of various various screening test(SRC). alpha-Amyl cinnamaldehyde, present at 100 mg/L, reached 51% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(6).

- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), alpha-amyl cinnamaldehyde, which has an estimated vapor pressure of 0.00431 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 alpha-amyl cinnamaldehyde 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 7.2 hours(SRC), calculated from its rate constant of 5.4X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(2). Vapor-phase alpha-amyl cinnamaldehyde is also degraded in the atmosphere by reaction with ozone(SRC); the half-life for this reaction in air is estimated to be 12.6 hours(SRC), calculated from its rate constant of 2.2X10-17 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(2).
