HEPATOCYTES FROM LIVERS OF RATS FED A SEMISYNTHETIC VITAMIN E-SUPPLEMENTED DIET WERE SLIGHTLY MORE PROTECTED FROM PEROXIDATION AND CELLULAR DAMAGE INDUCED BY BROMOTRICHLOROMETHANE TREATMENT THAN WERE HEPATOCYTES FROM RATS FED A VITAMIN E-DEFICIENT DIET.

WHEN INCUBATED FOR 15 MIN IN AIR WITH RAT LIVER MICROSOMES FROM PHENOBARBITAL-TREATED RATS, A NADPH-GENERATING SYSTEM, AND GSH (5 MILLIMOLAR), BROMOTRICHLOROMETHANE WAS CONVERTED TO DIGLUTATHIONYL DITHIOCARBONATE.

WHEN ISOLATED RAT HEPATOCYTES WERE INCUBATED WITH 2 MILLIMOLAR BROMOTRICHLOROMETHANE, INCR IN THE NUMBER OF CELLS TAKING UP TRYPAN BLUE, RELEASING LACTATE DEHYDROGENASE OR FORMING MALONDIALDEHYDE WAS OFFSET BY ADDING 1X10-4 MOLAR 2-HYDROXYESTRADIOL OR (+)-CYANIDANOL-3.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 567(SRC), determined from an estimated log Kow(2,SRC) and a regression-derived equation(3), indicates that bromotrichloromethane is expected to have low mobility in soil(SRC). Volatilization of bromotrichloromethane from moist soil surfaces is expected (SRC) given an estimated Henry's Law constant of 3.7X10-4 atm-cu m/mole(SRC), using a fragment constant estimation method(4). The potential for volatilization of bromotrichloromethane from dry soil surfaces may exist(SRC) based on a measured vapor pressure of 39 mm Hg(5). Based upon the highly halogenated structure of bromotrichloromethane, biodegradation in soil is expected to be slow(6,SRC).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 567(SRC), determined from an estimated log Kow of 2.5(2,SRC) and a regression-derived equation(3), indicates that bromotrichloromethane is expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 3.7X10-4 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 3.7 hrs and 6.6 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 49(SRC), from an estimated log Kow(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is moderate. Based upon the highly halogenated structure of bromotrichloromethane, biodegradation in water is expected to be slow(7).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), bromotrichloromethane, which has a measured vapor pressure of 39 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Based on bromotrichloromethane's structural similarity to bromotrifluoromethane, it is expected to slowly degrade in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for bromotrichloromethane's reaction in air is estimated to be greater than 44 years(3), based on bromotrifluoromethane's rate constant of <5.0X10-16 cu cm/molecule-sec at 25 °C(3). Photolysis may occur based on bromotrichloromethane's structural similarity to other halogenated methane compounds but not at an environmentally important rate(4).

The Koc of bromotrichloromethane is estimated as approximately 567(SRC), using an estimated log Kow of 2.5(1,SRC) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that bromotrichloromethane is expected to have low mobility in soil(SRC).

An estimated BCF value of 49 was calculated for bromotrichloromethane(SRC), using an estimated log Kow of 2.5(1,SRC) and a regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is moderate(SRC).
