Volatilization of 3-chloro-1,2-dihydroxypropane is not expected to be important from moist soil surfaces(SRC) given an estimated Henry's Law constant of 6.1X10-8 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Data regarding the aerobic biodegradation of 3-chloro-1,2-dihydroxypropane in soil are variablein screening tests, this compound reached 0(4) to 1%(5) of the theoretical BOD in 5 days and 68% of the theoretical BOD in 14 days(6). Under anaerobic conditions, 3-chloro-1,2-dihydroxypropane may be resistant to biodegradationusing an acclimated culture, only 26% of the initial 3-chloro-1,2-dihydroxypropane concentration was utilized in 90 days(7).AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 1(SRC), determined from structure estimation method(2), indicates that 3-chloro-1,2-dihydroxypropane should not adsorb to suspended solids and sediment in water(SRC). 3-Chloro-1,2-dihydroxypropane is not expected to volatilize from water surfaces(1,SRC) based on an estimated Henry's Law constant of 6.1X10-8 atm-cu m/mole(SRC), developed using a fragment constant estimation method(3). According to a classification scheme(4), an estimated BCF value of 0.2(1,SRC), from an estimated log Kow(9,SRC), suggests that bioconcentration in aquatic organisms is low(SRC). Data regarding the aerobic biodegradation of 3-chloro-1,2-dihydroxypropane in water are inconclusivein screening tests, this compound reached 0(5) to 1%(6) of the theoretical BOD in 5 days and 68% of the theoretical BOD in 14 days(7).

| TSCA Test Submissions | The effects of acute oral exposure to 3-chloro-1,2-propanediol (CPD) by gavage in male Wistar rats (20 in control group (water), 5/treated group, number of treated groups not reported) were determined. CPD (50 mg/kg) was administered orally and the rats were necropsied on the 11th day following dosing. There were differences between treated and control animals only in reduced sperm head counts. There were no significant differences between treated and control animals in the following: clinical observations, histopathology of the testes, and testes weights.Acute oral toxicity of 2-propenyloxy-2,3-epoxypropane (CAS# 96-24-2) was evaluated using 4 groups of Long-Evans rats (6 per group, sex not indicated) dosed by gavage at levels of 0.10, 0.13, 0.16, and 0.20 g/kg bodyweight. The use of controls was not reported. Animals were observed for 10 days post-treatment. Mortalities included 1 at the 0.10 g/kg dose level, 1 at the 0.13 g/kg level, 3 at the 0.16 g/kg level and 6 (all) at the 0.20 g/kg level. All deaths occurred within 48 hours post-treatment. The LD50 was determined to be 0.15 (0.13-0.18) g/kg bodyweight (method not reported). Clinical observations included sluggishness, prostration, flaccid paralysis of head and legs, hypnosis, dyspnea, and moderate lacrimation. Findings upon gross necropsy included irritation of the lungs and gastrointestinal tract, gelatinous pancreatic tissue, enlarged and hyperemic adrenals, granular-looking kidneys, as well as edematous conditions in some the lymphatic and lipoidal tissue of the peritoneum. Microscopic findings included inflammation in the biliary fatearly necrosis and regeneration of the tubular epitheliumand precipitated protein in and dilation of the tubules.Acute toxicity was evaluated in groups of 6 male Long-Evans rats fed a-monochlorohydrin at dose levels of 0.10, 0.13, 0.16, and 0.20 g/kg bw, by gavage, then observed for 10 days. Clinical signs of toxicity first appeared 22 hours after treatment and included prostration, hypnosis, sluggishness, dyspnea, moderate lacrimation, and flaccid paralysis of the head or legs. Rats that survived treatment lost weight during the observation period. The treatment killed 1, 1, 3, and 6 rats from the lowest to highest dose groups, respectively. Rats that died had severe diffuse irritation of the lungs with hemorrhagic lesions and marked pleural effusionslight to severe irritation of the gastrointestinal tracts with some friable liversslight ascitesenlarged, hyperemic adrenalspale, swollen, granular-looking kidneysgelatinous pancreatic tissueand occasionally, edematous lymphatic and lipoidal tissue of the peritoneum. Rats that survived treatment had hyperemia of the lungs and granular-looking kidneys. Histological abnormalities included acute inflammation in the hilar fat, and, in the kidneys, early necrosis of the tubular epithelium with precipitated protein in the tubules, and stages of regeneration of epithelium with dilation of tubules and presence of casts. The LD50 value was 0.15 g/kg bw.Acute toxicity was evaluated in groups of 6 male Webster mice fed a- monochlorohydrin at dose levels of 0.10, 0.13, 0.17, and 0.22 g/kg bw, by gavage, then observed for 10 days.
