- Environmental Bioconcentration: An estimated BCF of 500 was calculated in fish for D&C Green No. 6(SRC), using an estimated log Kow of 8.69(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 4.8X10+6(SRC), determined from a structure estimation method(2), indicates that D&C Green No. 6 is expected to be immobile in soil(SRC). Volatilization of D&C Green No. 6 from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.5X10-16 atm-cu m/mole(SRC), using a fragment constant estimation method(3). D&C Green No. 6 is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 7.0X10-13 mm Hg at 25 °C(SRC), determined from a fragment constant method(4). D&C Green No. 6 was shown to be susceptible to photolysis on soil, with two photoproducts detected, not identified(5). Biodegradation data in soil were not available(SRC, 2011). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 4.8X10+6(SRC), determined from a structure estimation method(2), indicates that D&C Green No. 6 is 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 1.5X10-16 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 500(SRC), from an estimated log Kow of 8.69(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 in water were not available(SRC, 2011). 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), D&C Green No. 6, which has an estimated vapor pressure of 7.0X10-13 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase D&C Green No. 6 may be removed from the air by wet or dry deposition(SRC). D&C Green No. 6 absorbs light at wavelengths 644 nm(3), and therefore may be susceptible to direct photolysis by sunlight(SRC). Source: Hazardous Substances Data Bank (HSDB)
