Ethylene dibromide degraded readily in primary sewage sludge suspensions under both aerobic and anaerobic conditions(1); under aerobic conditions, degradation occurred within days, while under anaerobic conditions, degradation took 5-6 weeks(1). In three day die-away tests using Japanese river and seawater, ethylene dibromide was observed to have moderate degradation (21-35% degradation)(2). Low concs of ethylene dibromide (<100 ug/l) were biotransformed completely within 2 weeks by a reductive dehalogenation under methanogenic conditions in a continuous-flow column(3); sterile controls showed that some abiotic degradation was also occurring, but microbial degradation was dominant(3). In a microcosm study simulating methanogenic conditions found in aquifer material, ethylene dibromide was found to biodegrade relatively rapidly(4); after 16 weeks of incubation, greater than 99% of initial ethylene dibromide was transformed(4); in sterile controls, only 20% was transformed after 40 weeks(4).
12.3 Bioaccumulative potentialA BCF for ethylene dibromide has been measured to be < 1(1). Orange red killifish exposed to an aqueous solution containing ethylene dibromide at 15 and 150 ug/l had a BCF ranging from <3.5-14.9 and 1.6-3.2, respectively(2). According to a classification scheme(3), these BCF values suggest the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soilEthylene dibromide exhibits slow to moderate adsorption to soil with measured Koc values ranging from 14 to 160(1). According to a classification scheme(2), these Koc values suggest that ethylene dibromide is expected to have high to very high mobility in soil.
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packagingContainers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
