 Trichloroethane, 1,1,1- (EHC 136, 1992)
Trichloroethane is distributed widely in body tissues and crosses the blood-brain and placental barriers.
(1984), the trichloroethane concentrations in blood and expired air were proportional to the exposure concentration after 6 h of exposure and indicated that about 25% of the 1,1,1-trichloroethane inhaled during the exposure was absorbed.
The same study showed that when trichloroethane was applied soaked in a cotton wool pad and bandaged to the shaven belly of a rabbit slight reddening and scaliness occurred, but this only increased slightly with repeated applications.

Trichloroethane (methyl chloroform) toxicity is characterized by anesthetic effects, such as lightheadedness and loss of coordination.
Trichloroethane (methyl chloroform) functions as a degreaser, dry cleaning agent, and solvent in paints, glues, and aerosols.
Trichloroethane can also be found in some household products (eg, degreasers, glues, etc).

 ATSDR - ToxFAQs™: 1,1,1-Trichloroethane
1,1,1 Trichloroethane is a synthetic chemical that does not occur naturally in the environment.
No 1,1,1 trichloroethane is supposed to be manufactured for domestic use in the United States after January 1, 2002 because it affects the ozone layer.
Because 1,1,1 trichloroethane was used so frequently in home and office products, you are likely to be exposed to higher levels indoors than outdoors or near hazardous waste sites.

Of those releases, 865,357 pounds were air emissions, 667 pounds were surface water discharges; none was released by underground injection; 5,195 pounds were released to land; and, 30,793 pounds were transferred off-site for disposal.
In 1998, 11,362,810 pounds of trichloroethane were managed; 1,843,338 pounds were recycled on-site; 164,553 pounds were recycled off-site; 3,006,489 pounds were used for energy recovery on-site; 2,727,850 pounds were used for energy recovery off-site; 1,865,310 pounds were treated on-site; 882,980 pounds were treated off-site; 872,290 pounds were released on and off site.
The 10 states in which the largest amount of Trichloroethane were released in 1998 were: Louisiana (155,028 pounds); California (123,344 pounds); Utah (113,849 pounds); Ohio (74,909 pounds); New jersey (64,461 pounds); Georgia (54,303 pounds); Pennsylvania (29,759 pounds); New York (26,505 pounds); Connecticut (23,963 pounds); and Florida (21,585 pounds).

 1,1,1-trichloroethane (UK PID)
Studies with human volunteers (males), exposed by inhalation to 1,1,1-trichloroethane at concentrations from around 35ppm to 350ppm for 6 hours demonstrated that about 25-40 % of the trichloroethane inhaled was absorbed by the lungs.
In view of the findings and subsequent police investigations the cause of death was concluded to be acute ventricular dysrhythmia due to inhalation of trichloroethane.

 Coffee   (Site not responding. Last check: 2007-10-30)
These concerns have almost no basis however, as the solvents in question evaporate between 80-90 degrees Celsius, and coffee beans are decaffeinated before roasting, which occurs at approximately 200 degrees Celsius.
As such, these chemicals, namely trichloroethane and methylene chloride, are present in trace amounts at most, and neither pose a significant threat to unborn children.
Women still worried about chemical solvents in decaffeinated coffee should opt for beans which use the Swiss Water process, where no chemicals other than water are used, although higher amounts of caffeine remain.

ROUTES OF EXPOSURE: Humans can be exposed dermally and by inhalation of air at occupational sites, from ambient air, household products containing 1,1,1-Trichloroethane (cleansers, polishes, lubricants, paint removers) or ingestion of contaminated food and water.
At high levels (greater than 5000 ppm), 1,1,1- trichloroethane can cause unconsciousness, respiratory depression and death.
Environmental Fate: When released into surface water 1,1,1 Trichloroethane will decrease in concentration due to evaporation.
