  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: 1,3-Dichloropropene, present at 100 mg/L, reached 3% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test which classified the compound as not readily biodegradable(1); additional degradation was observed yielding 3-chloro-2-propen-1-ol(1), possibly from hydrolysis and degradation of the hydrolysis products(SRC). A BOD dilution water study using settled domestic wastewater as the microbia1 inoculum found that 5-10 mg/L concentrations of 1,3-dichloropropene were degraded by 54-85% after 7 days of incubation with the faster rates achieved following weekly adaptations(1); however, the rate of biodegradation for 1,3-dichloropropene in natural waters cannot be inferred from this screening study data(3). Common soil bacteria were able to utilize 1,3-dichloropropene as a sole carbon source in pure culture studies(4). Twelve weeks after labeled cis- or trans-1,3-dichloropropene was added to soil and stored in sealed containers, 19% of the cis and 18% of the trans isomers remained in sandy loam and 10% of cis and 22% of trans isomer remained in medium loam(5). After 20 weeks, 5% and 4% of the cis and trans isomer, respectively, remained in sandy loam and 3% and 14%, respectively remained in the medium loam(5); the half-life of the applied dichloropropenes were 3-4 weeks; it was possible that some of the parent compound was lost by volatilization(5). 14C-1,3-Dichloropropene, added at 100 ug/g soil and incubated aerobically in the dark at 25°C, displayed half-lives of 1.8, 12.3, and 61 days using Wahiawa silt clay, Catlin silt loam, and Fuquay loamy sand, respectively(6); degradation products were 3-chloroallyl alcohol, 3-chloroacrylic acid, numerous minor carboxylic acid metabolites, and carbon dioxide(6). Degradation of 1,3-dichloropropene was greatly enhanced in amended soils compared to the unamended soil, and the degree of acceleration varied with the type as well as the rate of amendment(7); compost manure was more effective in stimulating 1,3-dichloropropene degradation than a less decomposed biosolid-manure mix; the acceleration in compost manure-amended soils was a combined result of enhanced chemical and microbial degradation, since sterilization only partially reduced the enhanced degradation(7). Complete mineralization of 1,3-dichloropropene, based on chloride release, can be a matter of years(8). A 5 ug/mL test compound added to a sediment sample from a drainage ditch at an agricultural field station in Marcham, England was readily converted to 3-chloropropionic acid(9). 1,3-Dichloropropene is degraded more rapidly in soil that has a history of treatment with this pesticide than in previously untreated soil(3). While the degradation rates of the cis- and trans- isomers are similar in untreated soil, degradation in previously treated soil has been shown to be more rapid for trans-1,3-dichloropropene than for cis-1,3-dichloropropene(3).

12.3 Bioaccumulative potential

An estimated BCF of 10 was calculated in fish for 1,3-dichloropropene(SRC), using a log Kow of 2.04 (average for the cis- and trans-isomers)(1) and a regression-derived equation(2). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

Measured Koc values of 23 and 26 for the cis- and trans- isomers of 1,3-dichloropropene, respectively, have been reported(1). The average Koc for 3 soils with organic carbon of 3.19%, 10.4%, and 55.1% was 27 and 28 for cis- and trans-1,3-dichloropropene, respectively(2). The average maximum Koc values were 20 for sand, 25 for loamy sand, and 41 and 42 for two clay soils(3). According to a classification scheme(4), these Koc values suggest that 1,3-dichloropropene is expected to have very high mobility in soil. The adsorption onto soil from the vapor is greater for the trans- than the cis- isomer(3). The adsorption isotherm for the vapor/soil system is linear(3). When 1,3-dichloropropene is used in farm fields, it is sprayed directly on the ground or injected into the soil(5). Once in the soil, it can exist as a gas or dissolved in water. 1,3-Dichloropropene can adsorb more strongly to soil when it is in the vapor phase than when it is dissolved in water(5). Vapor-phase adsorption can be approximately 3-times greater at 2°C than it is at 20°C, and adsorption isotherms measured for humus sand, peaty sand, and peat indicate vapor-phase Koc values ranging from 450 to 750(5). According to a classification scheme(4), these vapor-phase Koc values suggest that 1,3-dichloropropene may have moderate to low mobility in soil.
