SECTION 10: Stability and reactivity

Reactivity

NIOSH has recommended that ethylene dibromide be treated as a potential human carcinogen.

Decomposes on heating or on burning and on contact with hot surfaces. This produces toxic and corrosive fumes of hydrogen bromide and bromine (see ICSC 0107). Reacts violently with powdered aluminium, powdered magnesium, calcium, strong bases and strong oxidants. This generates fire and explosion hazard. Attacks some forms of plastic, rubber and coatings.

Chemical stability

1,2-Dibromomethane/ is stable and nonflammable.

Possibility of hazardous reactions

Not flammableETHYLENE DIBROMIDE slowly decomposes in the presence of light and heat. Turns brown upon exposure to light. Corrosive to iron and other metals. May decompose upon contact with alkalis. Incompatible with oxidizing agents. Reacts with sodium, potassium, calcium, powdered aluminum, zinc, magnesium and liquid ammonia. May attack some plastics, rubber and coatings. May poison platinum catalysts [Hawley]. Reacts as an alkylating agent (NTP, 1992).

Conditions to avoid

no data available

Incompatible materials

Incompatible with calcium, liquid ammonia, zinc, sodium, potassium, and strong oxidizers.

Hazardous decomposition products

At 240-270 deg C in a glass vessel, ethylene bromide decomposes into vinyl bromide & hydrogen bromide.

The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the liver and kidneys. This may result in tissue lesions. Exposure at high concentrations could cause lowering of consciousness and death. The effects may be delayed.

STOT-repeated exposure

Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the liver and kidneys, resulting in impaired functions. This substance is probably carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.

Aspiration hazard

A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.

SECTION 12: Ecological information

Toxicity

  • Toxicity to fish: LC50 - Oncorhynchus mykiss (previous name: Salmo gairdneri) - 1.13 mg/L - 96 h.
  • Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 11.61 mg/L - 48 h.
  • Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - > 4.48 mg/L - 72 h.
  • Toxicity to microorganisms: EC50 - activated sludge of a predominantly domestic sewage - > 1 000 mg/L - 3 h. Remarks:Respiration rate.

Persistence and degradability

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).

Bioaccumulative potential

A 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).

Mobility in soil

Ethylene 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.

Other adverse effects

no data available

SECTION 13: Disposal considerations

Disposal methods

Product

The 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 packaging

Containers 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.
