Environmental Impact There is no evidence of commercial production or sales of 1,3-dichloropropane in the United States of the isolated compounds or commercial mixtures. It is probably only used in small amounts possibly in laboratory synthesis. If released into the soil or water during its production and use, it would be lost primarily by volatilization (half-life 4 hr in a model river). It is poorly adsorbed by soil and may leach. In the air, it will disperse and degrade primarily by reaction with photochemically produced hydroxyl radicals (half-life 9.5 day). It will also be washed out by rain. Bioconcentration in fish will not be significant. Due to its limited production and use, exposure to the general public will be low.
Environmental Fate TERRESTRIAL FATE: If released on soil, 1,3-dichloropropane will probably rapidly volatilize. It may also leach into the ground since it is not strongly adsorbed by soil. There is no evidence as to its degradation in soil, however 1,2-dichloropropane shows little evidence of degradation in soil and the same may be true for 1,3-dichloropropane. AQUATIC FATE: If released into water, 1,3-dichloropropane will be lost primarily by volatilization (half-life 4 hr in a typical river). Adsorption to sediment will be low. ATMOSPHERIC FATE; If released into the atmosphere, 1,3-dichloropropane will primarily degrade by reaction with photochemically produced hydroxyl radicals (half-life 9.45 day). As it is moderately long lived, there is likely to be considerable dispersion from source areas. 1,3-Dichloropropane is moderately soluble (2870 mg/L ) and should be scavenged by rain. EFFL: 1,3-Dichloropropane was detected at levels of 18, 0.038, 0.008 and 0.012 ppm in leachate from four monitoring wells located at an abandoned organic chemical manufacturing facility near Salem, OH .
