Bioremediation
Halogenated Monoaromatics
Review of bioremediation approaches indicates that chlorobenzene can be degraded under anaerobic conditions, but the process is slow (Nijenhuis et al. 2007). The chemical is subject to aerobic biodegradation (Balcke 2002, Braeckevelt et al. 2008).

At inflow concentrations of 20 mg/L chlorobenzene, 0.19 mg/L 1,2-DCB, and 0.25 mg/L 1,4-DCB, the planted system showed high removals of chlorobenzene and 1,4-DCB after only 2 m of the flow path with averages of 48% chlorobenzene and 38% 1,4-DCB over all depths (71% chlorobenzene and 62% 1,4-DCB in the upper layer of the wetland). The unplanted wetland showed its highest mean removals only after 4 m of the flow path with 35% chlorobenzene and 32% 1,4-DCB. 1,2-DCB was not removed in either system. View abstract

Review of bioremediation approaches indicates that 1,2-DCB can be degraded under anaerobic conditions, but the process produces benzene as a final product (Fung et al. 2009). The compound is subject to aerobic biodegradation (Lawrence 2006, Werner and Tiehm 1999).

Review of bioremediation approaches indicates that 1,3-DCB can be degraded under anaerobic conditions, but the process produces benzene as a final product (Fung et al. 2009). The compound is subject to aerobic biodegradation (Lawrence 2006, Werner and Tiehm 1999).

Review of bioremediation approaches indicates that while 1,2,4-TCB can be degraded under anaerobic conditions, the process produces benzene as a final product (Fung et al. 2009). This chemical is subject to aerobic biodegradation (Lawrence 2006).
