<em>Biological.</em> 1,2-Dichloropropane showed significant degradation with gradual adaptation in a static-culture flask-screening test (settled domestic wastewater inoculum) conducted at 25°C. At concentrations of 5 and 10 mg/L, percent losses after 4 weeks of incubation were 89 and 81, respectively. The amount lost due to volatilization was only 0–3% (Tabak et al., 1981). <br/> <em>Soil.</em> Boesten et al. (1992) investigated the transformation of 14C-labeled 1,2-dichloropropane under laboratory conditions of three sub-soils collected from the Netherlands (Wassenaar low-humic sand, Kibbelveen peat, Noord-Sleen humic sand podsol). The groundwater saturated soils were incubated in the dark at 9.5–10.5°C. In the Wassenaar soil, no transformation of 1,2-dichloropropane was observed after 156 days of incubation. After 608 and 712 days, however, >90% degraded to nonhalogenated volatile compounds which were detected in the headspace above the soil. These investigators postulated these compounds could be propylene and n-propane in a ratio of 8:1. Degradation of 1,2- dichloropropane in the Kibbelveen peat and Noord-Sleen humic sand podsoil was not observed possibly because the soil redox potentials in both soils (50–180 and 650–670 mV, respectively) were higher than the redox potential in the Wassenaar soil (10–20 mV). <br/> <em>Groundwater.</em> According to the U.S. EPA (1986) 1,2-dichloropropane has a high potential to leach to groundwater. <br/> <em>Photolytic.</em> Distilled water irradiated with UV light (λ= 290 nm) yielded the following photolysis products: 2-chloro-1-propanol, allyl chloride, allyl alcohol and acetone. The half-lives in distilled water and distilled water containing hydrogen peroxide were 50 and 30 minutes, respectively (Milano et al., 1988).<br/> <em>Chemical/Physical.</em> Hydrolysis of 1,2-dichloropropane in distilled water at 25°C produced 1-chloro-2-propanol and hydrochloric acid (Milano et al., 1988). The calculated hydrolysis half-life at 25°C and pH 7 is 15.8 years (Ellington et al., 1988). Ozonolysis yielded carbon dioxide at low ozone concentrations (Medley and Stover, 1983).<br/> Emits toxic chloride fumes when heated to decomposition (Lewis, 1990).
