Epichlorohydrin effect on the skin, eyes, and respiratory tract may be delayed for several hours.
Epichlorohydrin causes dermatitis.
Inhalation of epichlorohydrin causes irritation of the eyes and throat.
|Environmental Impact|| Epichlorohydrin may be released to the atmosphere and in wastewater during its
production and use in epoxy resins, glycerin manufacture, as a chemical intermediate in the
manufacture of other chemicals, and other uses. If released into water it will be lost primarily by
evaporation (half-life 29 hr in a typical river) and hydrolysis (half-life 8.2 days). It will neither
adsorb appreciably to sediment nor bioconcentrate in fish. If spilled on land, it will evaporate and
leach into the groundwater where it will hydrolyze. Biodegradation and chemical reactions with
ions and reactive species may accelerate its loss in soil and water but data from field studies are
lacking. In the atmosphere, epichlorohydrin will degrade by reaction with photochemically
produced hydroxyl radicals (est half-life 4 days). There is a lack of monitoring data for
epichlorohydrin in all but occupational settings. Humans will primarily be exposed to chlorohydrin
in occupational settings.
|Environmental Fate|| TERRESTRIAL FATE: If spilled on land, epichlorohydrin will evaporate into the
atmosphere and leach in soil. Although data are lacking, it is probable that biodegradation and
chemical degradation will occur in the soil based upon biodegradation screening studies and the
rapid hydrolysis rate.
AQUATIC FATE: When released into water, epichlorohydrin will be lost by evaporation (half-life
29 hrs. in a typical river) and hydrolyze (half-life 8.2 days) (produce 1-chloropropan-2,3-diol). In
seawater it will additionally react with chloride ions which will reduce its overall half-life to about
5.3 days producing 1,3-dichloro-2-propanol as well as the hydrolysis product. Biodegradation is
also likely to occur as is reaction with radicals, but no estimates for the rate of these processes in
natural waters could be found.
ATMOSPHERIC FATE: When released to the atmosphere, epichlorohydrin will degrade by
reaction with photochemically produced hydroxyl radicals (estimated half-life 4 days; faster under
photochemical smog conditions). It is somewhat soluble in water and will therefore be subject to
wash-out by rain.
