- Environmental Bioconcentration: An estimated BCF of 27 was calculated in fish for dimethomorph(SRC), using a log Kow of 2.68(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 5690(SRC), determined from a structure estimation method(2), indicates that dimethomorph is expected to be immobile in soil(SRC). Volatilization of dimethomorph from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.0X10-15 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Dimethomorph is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 7.39X10-9 mm Hg at 25 °C(4). Biodegradation data in soil were not available(SRC,2012).

- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 5690(SRC), determined from a structure estimation method(2), indicates that dimethomorph 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 1.0X10-15 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 27(SRC), from its log Kow of 2.68(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Dimethomorph is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(6). Biodegradation data in water were not available(SRC, 2012). 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), dimethomorph, which has a vapor pressure of 7.39X10-9 mm Hg at 25 °C(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase dimethomorph may be removed from the air by wet or dry deposition(SRC). Dimethomorph contains chromophores that absorb at wavelengths >290 nm(3) and, therefore, may be susceptible to direct photolysis by sunlight(SRC). Source: Hazardous Substances Data Bank (HSDB)
