CAS number: 78-87-5
Screening test here reported showed that 1,2-dichloropropane is not
inherently biodegradable as only 11.7% of degradation was observed after
28 days. No simulation was deemed to be performed as 1,2-dichloropropane
is not expected to segregate in the water and sediment compartments due
to its attitude to volatise in the atmospheric compartment.
no biodegradation of 1,2-dichloropropane was detected when the substance
(150 mg/l) was incubated aerobically with municipal activated sludge
(1,000 mg/l mixed liquor suspended solids) for 28 days in an OECD 302B
(modified EMPA Zahn-Wellens test), conducted according to GLP
there are published examples of acclimated municipal and other systems
where 1,2-dichloropropane does undergo biodegradation, including
addition of co-factors (acetate and methanol), and enrichment of
cultures (Hauck and Hegemann, 1999; Hardyet
1999). It is unknown if such conditions exist or if biodegradation
occurs in the environment. However water, soil, and sediment
compartments are not considered of concern for 1,2-dichloropropane, due
to its attitude to segregate in air.
