1,1,1,2-Tetrachloroethane: Environmental effects
Description
1,1,1,2-Tetrachloroethane will exist as a gas if released to the atmosphere. It evaporates from soil and water when they are exposed to the air. In the air when it reacts into other chemicals, it takes a long time. It has moderate acute (short-term) toxicity on aquatic life. It has moderate chronic (long-term) toxicity to aquatic life. Chronic and acute effects on plants, birds or land animals have not been determined. 1,1,1,2-Tetrachloroethane does not bioaccumulate. (This information is based upon the studies on 1,1,2,2-Tetrachloroethane.)
Entering the environment
Industrial emissions of 1,1,1,2-Tetrachloroethane can produce elevated concentrations in the atmosphere around the source. Since it takes a long time to breakdown in the air it is likely to spread far from where it is used. Most of the releases are to the air, releases to the soil and water quickly evaporate to the air. (This information is based upon the studies on 1,1,2,2-Tetrachloroethane.)
Where it ends up
1,1,1,2-Tetrachloroethane enters the air during production, use and transporting it. 1,1,1,2-Tetrachloroethane and its products of degradation contribute to photochemical smog. Although most of the 1,1,1,2-Tetrachloroethane released is to the air, when released to the soil it will either evaporate or leach into the ground water (bores).
