AEROBIC: An unspecified initial concentration of 1,4-dichlorobenzene was biodegraded between 25 and 90 percent in soil column experiments using sediment from the Rhine River over a 300 day incubation period(1). Dichlorobenzene isomers were slowly biodegraded (6.3% of theoretical CO2 evolution in 10 weeks) in an alkaline soil sample(2). The first-order biodegradation rate of 1,4-dichlorobenzene in a biofilm system was 5.0-20.0X10-4 days-1, corresponding to half-lives on the order of a year or longer(3). 1,4-Dichlorobenzene was not biodegraded in aquifers from Vejen and Grindsted, Denmark during a 50 day incubation period(4). 1,4-Dichlorobenzene was found to be degradation-resistant using the Japanese MITI test(5,6); at 100 mg/L, 1,4-dichlorobenzene achieved 0% of its theoretical BOD using an activated sludge inoculum at 30 mg/L incubated over a 4 week period(6).
12.3 Bioaccumulative potentialA mean BCF value of 78 was measured in mosquito fish exposed to 57-233 ug/L of 1,4-dichlorobenzene during 1 to 4 day incubation periods(1). Mean BCF values of 370 to 720 were experimentally determined for rainbow trout exposed to unspecified concns of 1,4-dichlorobenzene up to 119 days in laboratory aquariums(2). A whole body BCF of 60 was determined for bluegill sunfish exposed to 1,4-dichlorobenzene over a 28-day period in a continuous flow system(3). BCF values of 33 to 73 were measured in carp exposed to 2 ug/L of 1,4-dichlorobenzene during an 35 day incubation period and BCF values of 47 to 190 were measured in carp exposed to 0.2 ug/L of 1,4-dichlorobenzene during a 35 day incubation period(4). According to a classification scheme(5), these BCF values suggest that bioconcentration in aquatic organisms is moderate to high, provided the compound is not metabolized by the organism(SRC)..
12.4 Mobility in soilAn experimental Koc value of 273(1) was determined for 1,4-dichlorobenzene in silt loam soil and a value of 390 was reported in Lincoln fine sand(2). According to a recommended classification scheme(3), these Koc values suggest that 1,4-dichlorobenzene has moderate mobility in soil(SRC). A log Koc value of 4.8 was measured for 1,4-dichlorobenzene from sediment of Lake Ketelmeer, Netherlands(4).
