  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

Information ... concerning the biodegradation potential of chlorobenzene indicates that this compound will ... eventually degrade, but not at an environmentally important rate unless the microorganisms present are already growing on another hydrocarbon source.

12.3 Bioaccumulative potential

BCF values of 4.3 to 39.6 and 3.9 to 22.8 were measured for chlorobenzene in carp (Cyprinus carpio) at chemical concentrations of 0.15 and 0.015 mg/L, respectively(1). A log BCF of 2.65 has been reported for chlorobenzene in fathead minnows(2) that corresponds to a BCF of 450(SRC). A BCF of 41 was measured in bluegill fish (Lepomis macrochirus) over a 14-day exposure period(3). According to a classification scheme(4), these BCF values suggest the potential for bioconcentration in aquatic organisms ranges from low to high, provided the compound is not metabolized by the organism(SRC). Dissolved organic matter that is present in interstitial water may greatly reduce the amount of a chemical that is available for accumulation(5). In one set of experiments, midge larvae were found to accumulate higher tissue-to-sediment ratios of chlorobenzene from a low-organic content sediment than from a high-organic content sediment(5). BCFs of 0.25 (from sediment), 11 (from interstitial water), and 10 (overlying water) were measured for midge larvae exposed to chlorobenzene under equilibrium exposure conditions(5). BCFs of 0.15 (from sediment), 310 (from interstitial water), and 5 (from overlying water) were measured for midge larvae exposed to chlorobenzene sorbed to high-organic content sediment under nonequilibrium exposure conditions(5). BCFs of 0.72 (from sediment), 18 (from interstitial water), and 2,187 (from overlying water) were measured for midge larvae exposed to chlorobenzene sorbed to low-organic content sediment under nonequilibrium exposure conditions(5).

12.4 Mobility in soil

Koc values of 313.1 and 146.5 were measured on Captina silt loam (1.49% organic carbon) and McLaurin sandy loam, (0.66% organic carbon), respectively(1). Equilibrium sorption constant (Ks) values of 0.295 and 0.09 were determined in Eustis fine sand (13 g/kg clay, 32 g/kg silt, 955 g/kg sand, 3.9 g/kg organic carbon) and Tampa (6 g/kg clay, 23 g/kg silt, 971 g/kg sand, and 1.3 g/kg organic carbon) soils, respectively(2); corresponding Koc values are 76 and 69(SRC). Equilibrium sorption coefficients of 0.014 and 10.20 were measured on Borden (98% sand, 1% silt, 1% clay, 0.29% organic carbon) and Mt. Lemmon (60.3% sand, 24.0% silt, 15.7% clay, 12.6% organic carbon) soils, respectively(3); corresponding Koc values are 4.8 and 81(SRC). According to a classification scheme(4), these Koc values suggest that chlorobenzene is expected to have moderate to very high mobility in soil(SRC). The sorption isotherm for chlorobenzene onto muck soil (49.0% organic carbon) was linear(5). A Kd value of 166.34 was measured for chlorobenzene using dewatered activated sludge (18% solids) that had been dried and sieved; 3.28% of the chlorobenzene was desorbed during the desorption phase of the experiment(6). Partition coefficients of 0.35, 0.33, and 0.38 were measured for chlorobenzene on primary sludge, mixed liquor solids, and digested sludge, respectively(7). Sorption coefficients of 0.48 and 0.29 were measured on primary sludge and anaerobically digested sludge, respectively(8). Partition coefficients of 48 and 29 were measured in high organic carbon (14.5%) and low organic carbon (3.6%) Sherman Island sediments, respectively(9).
