Environmental Fate/Exposure Summary :
Acetone's
production and use as a solvent for fats, oils, waxes, resins, rubbers,
plastics, pharmaceuticals and rubber cements may result in its release to the
environment through various waste streams. Its use as an extracting reagent and
starting material or intermediate in the manufacture of chemical products will
also lead to its release to the environment. Acetone
occurs naturally as a metabolic byproduct of plants and animals and is released
into the atmosphere by volcanoes and forest fires. Based on an experimental
vapor pressure of 231 mm Hg at 25 deg C, acetone
is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase acetone
is degraded in the atmosphere by reaction with photochemically-produced hydroxyl
radicals with an estimated atmospheric half-life of 71 days. Acetone
also undergoes photodecomposition by sunlight with an estimated half-life of
about 80 days. Acetone is expected to
have very high mobility in soils based upon an estimated Koc value of 1.
Volatilization from dry soil surfaces is expected based upon the vapor pressure
of this compound. Volatilization from moist soil surfaces is also expected based
upon the measured Henry's Law constant of 1.87X10-5 atm-cu m/mol. This compound
is expected to biodegrade under aerobic and anaerobic conditions. In water, acetone
is not expected to adsorb to suspended solids or sediment based upon its
estimated Koc value. Volatilization from water surfaces is expected to be an
important environmental fate process given its estimated Henry's Law constant.
Estimated half-lives for a model river and model lake are 38 and 333 hours,
respectively. Experimentally determined volatilization half-lives in a shallow
stream were measured in the range of 8-18 hours. Bioconcentration in aquatic
organisms is considered low based upon an estimated BCF value of 1. Occupational
exposure may be through inhalation and dermal contact with this compound at
workplaces where acetone is produced
or used. The general population may be exposed to acetone
through the use of commercially available products containing this compound such
as paints, adhesives, cosmetics, and
rubber cements. Exposure will also arise from inhalation of ambient air,
ingestion of drinking water, and food that contains acetone.

Probable Routes of Human Exposure :
The general population may be exposed to acetone
through the use of commercially available products containing this compound such
as paints, adhesives, cosmetics, and
rubber cements(SRC). Exposure will also arise from inhalation of ambient air,
ingestion of drinking water, and food that contains acetone(SRC).
The average blood concn of acetone in
600 non-occupationally exposed persons in the US was 3,100 ppb(1).
