Chemicals  can  be released lo the envi-
ronment as a result of llicir manufacture.
processing, and use   Flic  EPA  has  dc-
\eloped  information summaries on  se-
lected  chemicals  to describe  how  you
might be exposed  to these chemicals, how
exposure to them might affect you and the
environment, what happens to them in the
environment,  who regulates  them,  and
whom  to contact  for additional informa-
tion  EPA is committed lo reducing envi-
ronmental releases of chemicals  through
source reduction and other  practices that
reduce crcaUon of pollutants

 WHAT IS 2-METIIOXYETHANOL,
    HOW IS IT USED, AND  HOW
       MIGHT I  BE EXPOSED?

        2-McthoxyctJianol  (also  called
cthylcnc  glycol   monomcthyl  ether  or
EGME) is a colorless, flammable liquid It
docs not occur naturally but is produced in
large  amounts (estimated not  lo exceed
 100  million pounds  per year) by three
companies  in ihc  United States  I IS  de-
mand for EGME  has declined during  Ihc
late I'WOs and is likely lo continue lo fall
The largcsl  users of EGME arc companies
that add it to jet fuel as a de-icer Currently
this use of EGME is declining in the US
Companies   use   EGME  lo  dissolve
chemicals such as cellulose acetate, vari-
ous resins used in  the electronics industry,
and certain dyes.   Other companies  use
EGME to make perfume and photographic
film  It can also be added lo quick-drying
varnishes,  enamels,  nail  polishes,  and
wood stains

        Exposure lo EGME can occur in

-------
the workplace or in (he environment following
releases to  air, walcr, land, or groundwalcr
The number of consumer products that conlain
2-mcthoxycthanol is declining  ll is unlikely
thai this will be a major source of exposure lo
EGME in ihc fulure EGME enters the bod\
when  brcatJied in  with  contaminated air or
when  consumed with conlammalcd  food or
water  It is also absorbed through skin contact
2-Mcthoxyethanol does not remain in the body
due lo its breakdown and removal in urine or
in expired air
         WHAT HAPPENS TO
    2-METHOXYETHANOL IN THE
           ENVIRONMENT?

       2-Methoxycthanol evaporates  when
exposed to air  ll dissolves completely mixed
with water  Mosl direct releases of EGME to
the  environment arc to  air   EGME  also
evaporates from water and soil exposed to air
Once in air, 2-mcthoxycthanol breaks down lo
other chemicals  Because il is a liquid lhal
does not bind well lo soil, EGME lhal makes
its way inlo the ground can move through the
ground and enter groundwalcr   Plants arid
animals   arc    nol   likely    to    store
2-rncthoxvcthanol
  HOW DOES 2 METHOXYETHANOL
 AFFECT HUMAN HFALTH AND THE
           ENVIRONMENT?

       Effects of 2-mclhoxycthanol on  hu-
man health and  the environment depend on
how much EGME is  present  and Ihc lenglh
and frequency of exposure   Effects also de-
pend on the health of a person or the condition

-------
of the environment  when  exposure
occurs.

       Brcalhing  EGME  for  short
periods of Ume adversely affects the
human nervous system Effects  range
from  di//mess to  unconsciousness
EGME  also   adversely  aflects the
blood, the liver, the kidneys, and the
lesles  Laboratory studies show that
EGME causes similar effects in ani-
mals    Direct contact  with  liquid
2-methoxvcthanol   irritates  the  skin
Contact  with  EGME liquid or vapor
can cause eye damage

       Human health effects associ-
ated  with breathing or otherwise con-
suming small  amounts of EGME over
long  periods of time are not known
Laboratory  studies show mat  repeat
exposure to small amounts of EGME
adversely  afTccts  the  reproductive
system of animals, especially  males
Exposure to small amounts of EGME
also  causes animals  to give birth  to
malformed offspring  Repeal exposme
to    larger    amounts    of    the
2-mcthoxyclhanol    causes   adverse
nervous system and  blood  effects  in
animals

       2-Mclhoxyclhanol by itself is
not likely to cause  environmental harm
at levels  normally found  in the envi-
ronment  EGME can contribute to the
formation  of photochemical   smog
when it  reacts with other volatile or-
ganic carbon substances in air
