If swallowed, this material may irritate the mucous membranes of the mouth, throat, and
esophagus. It can be readily absorbed by the stomach and intestinal tract. Symptoms
include a burning sensation of the mouth and esophagus, nausea, vomiting, dizziness,
staggered gait, drowsiness, loss of consciousness and delirium, as well as additional central
nervous system (CNS) effects.
Due to its light viscosity, there is a danger of aspiration into the lungs during swallowing and
subsequent vomiting. Aspiration can result in severe lung damage or death. Cardiovascular
effects include shallow rapid pulse with pallor (loss of color in the face) followed by flushing
(redness of the face). Also, progressive CNS depression, respiratory insufficiency and
ventricular fibrillation leads to death.
Chronic Health Effects Intentional misuse by deliberately concentrating and inhaling gasoline can be harmful or fatal.
Summary Altered mental state, drowsiness, peripheral motor neuropathy, irreversible brain damage
("Petrol Sniffers Encephalopathy"), delirium, seizures and sudden death are associated with
repeated abuse of gasoline or naphtha.
Chronic effects of ingestion and subsequent aspiration into the lungs may include
pneumatocele (lung cavity) formation and chronic lung dysfunction.

Autoignition 280癈 (536癋)
Temperature
Hazardous Combustion Carbon dioxide, carbon monoxide, smoke, fumes, unburned hydrocarbons, aldehydes and
Products other products of incomplete combustion.
Special Properties Flammable Liquid! This material releases vapors at or below ambient temperatures. When
mixed with air in certain proportions and exposed to an ignition source, its vapor can cause a
flash fire. Use only with adequate ventilation. Vapors are heavier than air and may travel
long distances along the ground to an ignition source and flash back. A vapor and air
mixture can create an explosion hazard in confined spaces such as sewers. If container is
not properly cooled, it can rupture in the heat of a fire.
Extinguishing Media SMALL FIRE: Use dry chemicals, carbon dioxide, foam, or inert gas (nitrogen). Carbon
dioxide and inert gas can displace oxygen. Use caution when applying carbon dioxide or
inert gas in confined spaces.
LARGE FIRE: Use foam, water fog, or water spray. Water May Be Ineffective. Water may
not extinguish the fire. Water fog and spray are effective in cooling containers and adjacent
structures. However, water can be used to cool the external walls of vessels to prevent
excessive pressure, autoignition or explosion. DO NOT use a solid stream of water directly
on the fire as the water may spread the fire to a larger area.
Firefighters must use full bunker gear including NIOSH-approved positive pressure

decomposition products and oxygen deficiencies. Evacuate area and fight the fire from a
maximum distance or use unmanned hose holders or monitor nozzles. Cover pooling liquid
with foam. Containers can build pressure if exposed to radiant heat; cool adjacent containers
with flooding quantities of water until well after the fire is out. Withdraw immediately from the
area if there is a rising sound from a venting safety device or discoloration of vessels, tanks,
or pipelines. Be aware that burning liquid will float on water. Notify appropriate authorities of
potential fire and explosion hazard if liquid enter sewers or waterways.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Take proper precautions to ensure your own health and safety before attempting spill control or clean-up. For
more specific information, refer to the Emergency Overview on Page 1, Exposure Controls and Personal
Protection in Section 8 and Disposal Considerations in Section 13 of this MSDS.
Flammable Liquid! Release causes an immediate fire or explosion hazard. Evacuate all
non-essential personnel from immediate area and establish a "regulated zone" with site
control and security. A vapor-suppressing foam may be used to reduce vapors. Eliminate all
ignition sources. All equipment used when handling this material must be grounded. Stop the
leak if it can done without risk. Do not touch or walk through spilled material. Remove
spillage immediately from hard, smooth walking areas. Prevent spilled material from entering
waterways, sewers, basements, or confined areas. Absorb or cover with dry earth, sand, or
other non-combustible material and transfer to appropriate waste containers. Use clean,
non-sparking tools to collect absorbed material.
For large spills, secure the area and control access. Prevent spilled material from entering
sewers, storm drains, other drainage systems, and natural waterways. Dike far ahead of a

liquid spill to ensure complete collection. Water mist or spray may be used to reduce or
disperse vapors; but, it may not prevent ignition in closed spaces. This material will float on
water and its run-off may create an explosion or fire hazard. Verify that responders are
properly HAZWOPER-trained and wearing appropriate respiratory equipment and
fire-resistant protective clothing during cleanup operations. In an urban area, cleanup spill as
soon as possible; in natural environments, cleanup on advice from specialists. Pick up free
liquid for recycle and/or disposal if it can be accomplished safely with explosion-proof
equipment. Collect any excess material with absorbant pads, sand, or other inert
non-combustible absorbent materials. Place into appropriate waste containers for later
disposal. Comply with all applicable local, state and federal laws and regulations.
SECTION 7. HANDLING AND STORAGE
FLAMMABLE LIQUID AND VAPOR. USE ONLY as a motor fuel. DO NOT siphon by
Handling
mouth. DO NOT use as a lighter fluid, solvent or cleaning fluid. Prior to handling or refueling,
stop all engines and auxillary equipment. Turn off all electronic equipment including cellular
telephones. DO NOT leave nozzle unattended during filling or refueling a vehicle. DO NOT
re-enter vehicle while refueling. Keep nozzle spout in contact with the container during the
entire filling operations.
A static electrical charge can accumulate when this material is flowing through pipes, nozzles
or filters and when it is agitated. A static spark discharge can ignite accumulated vapors
particularly during dry weather conditions. Always bond receiving containers to the fill pipe
before and during loading. Always keep nozzle in contact with the container throughout the
loading process. Do not fill any portable container in or on a vehicle. Special precautions,
such as reduced loading rates and increased monitoring, must be observed during "switch
loading" operations (i.e., loading this material in tanks or shipping compartments that
previously contained middle distillates or similar products).
A spill or leak can cause an immediate fire hazard. Keep containers closed and do not handle
or store near heat, sparks, or any other potential ignition sources. Do not contact with
oxidizable materials. Do not breathe vapor. Use only with adequate ventilation and personal
protection. Never siphon by mouth. Avoid contact with eyes, skin, and clothing. Prevent
contact with food and tobacco products. Do not take internally.
When performing repairs and maintenance on contaminated equipment, keep unnecessary
persons away from the area. Eliminate all potential ignition sources. Drain and purge
equipment, as necessary, to remove material residues. Follow proper entry procedures,
including compliance with 29 CFR 1910.146 prior to entering confined spaces such as tanks
or pits. Use gloves constructed of impervious materials and protective clothing if direct
contact is anticipated. Provide ventilation to maintain exposure potential below applicable
exposure limits. Use appropriate respiratory protection when concentrations exceed any
established occupational exposure level (See Section 8). Promptly remove contaminated
clothing. Wash exposed skin thoroughly with soap and water after handling.
Protect the environment from releases of this material. Prevent discharges to surface waters
and groundwater. Maintain handling, transfer and storage equipment in proper working order.
Misuse of empty containers can be dangerous. Empty containers may contain material
residues which can ignite with explosive force. Cutting or welding of empty containers
can cause fire, explosion, or release of toxic fumes from residues. Do not pressurize or
expose empty containers to open flame, sparks, or heat. Keep container closed and drum
bungs in place. All label warnings and precautions must be observed. Return empty drums
to a qualified reconditioner. Consult appropriate federal, state and local authorities before
reusing, reconditioning, reclaiming, recycling, or disposing of empty containers and/or waste
residues of this material.

A major epidemiological study concluded that there was no increased risk of kidney cancer
associated with gasoline exposures for petroleum refinery employees or neighboring
residents. Another study identified a slight trend in kidney cancers among service station
employees following a 30-year latency period. Two-year inhalation toxicity studies with fully
vaporized unleaded gasoline (at concentrations of 67, 292 and 2,056 ppm in air) produced
kidney damage and kidney tumors in male rats, but not in female rats or mice of either sex.
Results from subsequent scientific studies suggest that the kidney damage, and probably the
kidney tumor response, is limited to the male rat. The kidney tumors apparently were the
result of the formation of alpha-2u-globulin, a protein unique to male rats. This finding is not
considered relevant to human exposure. Under conditions of the study, there was no
evidence that exposure to unleaded gasoline vapor is associated with developmental toxicity.
Experimental studies with laboratory animals did suggest that overexposure to gasoline may
adversely effect male reproductive performance. Also, in laboratory studies with rats, the
maternal and developmental "no observable adverse effect level" (NOAEL) was determined
to be 9,000 ppm (75% of the LEL value). Female mice developed a slightly higher incidence
of liver tumors compared to controls at the highest concentration. In a four week inhalation
study of Sprague Dawley?rats, gasoline vapor condensate was determined to induce sister
chromatid exchanges in peripheral lymphocytes. IARC has listed gasoline as possibly
carcinogenic to humans (Group 2B).
Pentanes, all isomers:
Studies of pentane isomers in laboratory animals indicate exposure to extremely high levels
(roughly 10 vol.%) may induce cardiac arrhythmias (irregular heartbeats) which may be
serious or fatal.
Toluene:
Effects from Acute Exposure:
Deliberate inhalation of toluene at high concentrations (e.g., glue sniffing and solvent abuse)
has been associated with adverse effects on the liver, kidney and nervous system and can
cause CNS depression, cardiac arrhythmias and death. Case studies of persons abusing
toluene suggest isolated incidences of adverse effects on the fetus including birth defects.
Effects from Repeated or Prolonged Exposure:
Studies of workers indicate long-term exposure may be related to impaired color vision and
hearing. Some studies of workers suggest long-term exposure may be related to
neurobehavioral and cognitive changes. Some of these effects have been observed in
laboratory animals following repeated exposure to high levels of toluene. Several studies of
workers suggest long-term exposure may be related to small increases in spontaneous
abortions and changes in some gonadotropic hormones. However, the weight of evidence
does not indicate toluene is a reproductive hazard to humans. Studies in laboratory animals
indicate some changes in reproductive organs following high levels of exposure, but no
significant effects on mating performance or reproduction were observed. Case studies of
persons abusing toluene suggest isolated incidences of adverse effects on the fetus including
birth defects. Findings in laboratory animals were largely negative. Positive findings include
small increases in minor skeletal and visceral malformations and developmental delays
following very high levels of maternal exposure. Studies of workers indicate long-term
exposure may be related to effects on the liver, kidney and blood, but these appear to be
limited to changes in serum enzymes and decreased leukocyte counts. Studies in laboratory
animals indicate some evidence of adverse effects on the liver, kidney, thyroid, and pituitary
gland following very high levels of exposure. The relevance of these findings to humans is
not clear at this time.
Heptane, all isomers:

blood serum changes, CNS damage and narcosis. Effects may be increased by the use of
alcoholic beverages. Evidence of liver and kidney impairment were reported in workers
recovering from a gross over-exposure.
Effects from Prolonged or Repeated Exposure:
Impaired neurological function was reported in workers exposed to solvents including xylene.
Studies in laboratory animals have shown evidence of impaired hearing following high levels
of exposure. Studies in laboratory animals suggest some changes in reproductive organs
following high levels of exposure but no significant effects on reproduction were observed.
Studies in laboratory animals indicate skeletal and visceral malformations, developmental
delays, and increased fetal resorptions following extremely high levels of maternal exposure.
Adverse effects on the liver, kidney, bone marrow (changes in blood cell parameters) were
observed in laboratory animals following high levels of exposure. The relevance of these
observations to humans is not clear at this time.
Ethyl tertiary Butyl Ether (ETBE):
ETBE can cause eye, skin and mucous membrane irritation. In a four week inhalation study,
moderate ataxia was observed in rats at the highest dose level (4,000 ppm). The test
animals appeared normal within 15 minutes of termination of exposure. A no observed
adverse effect level (NOAEL) of 500 ppm was indicated by the study authors based on
neurotoxic effects. In two unpublished 90 day inhalation studies, rats and mice were exposed
six hour/day, five days/week at concentrations of 0, 500, 1750 and 5000 ppm of ETBE vapor.
The male rats exhibited time and concentration-dependent nephropathy consistent with
alpha-2?globulin formation. An ETBE NOAEL for male rats of 500 ppm was suggested
based on a finding of testicular lesions. In human studies with eight males, slight, but
significant (p<0.05) decreases in objective pulmonary function measures after exposure to
ETBE at concentrations of 25 and 50 ppm for two hours.
Tertiary-Amyl Methyl Ether (TAME):
TAME was found to be negative for the induction of structural chromosome aberrations (both
metabolically-activated and non-activated) in Chinese hamster ovary (CHO) cells. Inhalation
of TAME vapors at concentrations above 250 ppm produced reversible CNS depression in
rats and mice. In a four week inhalation study, increases in liver weights with no tissue injury
were observed in rats exposed to a TAME concentration of 500 ppm. Birth defects in mice
and fetotoxicity in both rats and mice were observed after inhalation exposures to maternally
toxic concentrations of TAME.
Methyl tertiary-Butyl Ether (MTBE):
Acute symptoms associated with human exposure to MTBE appear to be mild and transient.
In laboratory studies, rats and mice exposed to high doses of MTBE exhibited blood
chemistry changes and liver and kidney abnormalities. In laboratory studies, MTBE vapor
exposure at the high dose concentration was associated with an increased incidence of liver
tumors in female mice. Also, at high dose concentration exposures, MTBE was associated
with an increased incidence of kidney and testicular (Leydig cell) tumors in male rats.
Additional oncogenicity studies on rats resulted in testicular tumors following administration
by ingestion. These data are not generally considered relevant to humans. NTP has not
identified MTBE as either a known carcinogen or reasonably anticipated to be carcinogenic to
humans. In animal studies, developmental and reproductive toxicity related to MTBE
inhalation exposures was observed only at concentrations that were maternally toxic. MTBE
was shown to be maternally toxic at 4,000 and 8,000 ppm levels when mice were exposed for
six hours per day during their pregnancy. Also, a decrease in the number of successful
pregnancies and a reduction in birth weights were observed at these exposure levels. Birth
defects (cleft palate) were observed at the high dose level. These data suggest that the risk
of developmental and reproductive toxicity in humans is negligible as a result of anticipated

exposures to MTBE.
Diisopropyl Ether (DIPE):
Increased kidney and liver weights were observed in rats and mice in subchronic and chronic
inhalation studies of DIPE. Also, evidence of microscopic changes (hyaline droplets) were
reported in liver tissue and kidney tubules of rabbits and male rats exposed to DIPE at
concentrations of 7,100 ppm. These findings were similar those found in gasoline studies.
Overexposure by inhalation of pregnant rats to DIPE at concentrations of 3,095 and 6,745
ppm increased the frequency of rudimentary 14th ribs in the offspring. This effect was not
observed at exposure concentrations of 430 ppm. The significance of these findings to
human exposure is unclear.
Ethanol:
Inhalation exposure to ethanol vapor at concentrations above applicable workplace exposure
levels is expected to produce eye and mucus membrane irritation. Human exposure at
concentrations from 1000 to 5000 ppm produced symptoms of narcosis, stupor and
unconsciousness. Subjects exposed to ethanol vapor in concentrations between 500 and
10,000 ppm experienced coughing and smarting of the eyes and nose. At 15,000 ppm there
was continuous lacrimation and coughing. While extensive acute and chronic effects can be
expected with ethanol consumption, ingestion is not expected to be a significant route of
exposure to this product.
Butane, all isomers:
Studies in laboratory animals indicate exposure to extremely high levels of butanes (1-10 or
higher vol.% in air) may cause cardiac arrhythmias (irregular heartbeats) which may be
serious or fatal.
n-Hexane:
This material contains n-hexane. Long-term or repeated exposure to n-hexane can cause
permanent peripheral nerve damage. Initial symptoms are numbness of the fingers and toes.
Also, motor weakness can occur in the digits, but may also involve muscles of the arms,
thighs and forearms. The onset of these symptoms may be delayed for several months to a
year after the beginning of exposure. Co-exposure to methylethyl ketone or methyl isobutyl
ketone increases the neurotoxic properties of n-hexane. In laboratory studies, prolonged
exposure to elevated concentrations of n-hexane was associated with decreased sperm
count and degenerative changes in the testicles of rats.
Cumene:
Effects from Acute Exposure:
Overexposure to cumene may cause upper respiratory tract irritation and severe CNS
depression.
Effects from Prolonged or Repeated Exposure:
Studies in laboratory animals indicate evidence of adverse effects on the kidney and adrenal
glands following high level exposure. The relevance of these findings to humans is not clear
at this time.
Trimethylbenzenes, all isomers:
Studies of Workers:
Levels of total hydrocarbon vapors present in the breathing atmosphere of these workers
ranged from 10 to 60 ppm. The TCLo for humans is 10 ppm, with somnolence and
respiratory tract irritation noted.
Studies in Laboratory Animals:
In inhalation studies with rats, four of ten animals died after exposures of 2400 ppm for 24
hours. An oral dose of 5 mL/kg resulted in death in one of ten rats. Minimum lethal
intraperitoneal doses were 1.5 to 2.0 mL/kg in rats and 1.13 to 12 mL/kg in guinea pigs.
Mesitylene (1, 3, 5 Trimethylbenzene) inhalation at concentrations of 1.5, 3.0, and 6.0 mg/L
for six hours was associated with dose-related changes in white blood cell counts in rats. No
significant effects on the complete blood count were noted with six hours per day exposure

for five weeks, but elevations of alkaline phosphatase and SGOT were observed. Central
nervous system depression and ataxia were noted in rats exposed to 5,100 to 9,180 ppm for
two hours.
Benzene:
ORAL (LD50): Acute: 930 mg/kg [Rat]. 4700 mg/kg [Mouse].
INHALATION (LC50):
(VAPOR): Acute: 10000 ppm 7 hour(s) [Rat]. 9980 ppm 8 hour(s) [Mouse].
Studies of Workers Over-Exposed to Benzene:
Studies of workers exposed to benzene show clear evidence that over-exposure can cause
cancer of the blood forming organs (acute myelogenous leukemia) and aplastic anemia, an
often fatal disease. Studies also suggest over-exposure to benzene may be associated with
other types of leukemia and other blood disorders. Some studies of workers exposed to
benzene have shown an association with increased rates of chromosome aberrations in
circulating lymphocytes. One study of women workers exposed to benzene suggested a
weak association with irregular menstruation. However, other studies of workers exposed to
benzene have not demonstrated clear evidence of an effect on fertility or reproductive
outcome in humans. Benzene can cross the placenta and affect the developing fetus. Cases
of aplastic anemia have been reported in the offspring of persons severely over-exposed to
benzene.
Studies in Laboratory Animals:
Studies in laboratory animals indicate that prolonged, repeated exposure to high levels of
benzene vapor can cause bone marrow suppression and cancer in multiple organ systems.
Studies in laboratory animals show evidence of adverse effects on male reproductive organs
following high levels of exposure but no significant effects on reproduction have been
observed. Embryotoxicity has been reported in studies of laboratory animals but effects were
limited to reduced fetal weight and skeletal variations.
Ethylbenzene:
Effects from Acute Exposure:
ORAL (LD50), Acute: 3,500 mg/kg [Rat].
DERMAL (LD50), Acute: 17,800 uL/kg [Rabbit].
INTRAPERITONEAL (LD50), Acute: 2,624 mg/kg [Rat].
Effects from Prolonged or Repeated Exposure:
Findings from a 2-year inhalation study in rodents conducted by NTP were as follows: Effects
were observed only at the highest exposure level (750 ppm). At this level the incidence of
renal tumors was elevated in male rats (tubular carcinomas) and female rats (tubular
adenomas). Also, the incidence of tumors was elevated in male mice (alveolar and
bronchiolar carcinomas) and female mice (hepatocellular carcinomas). IARC has classified
ethyl benzene as "possibly carcinogenic to humans" (Group 2B). Studies in laboratory
animals indicate some evidence of post-implantation deaths following high levels of maternal
exposure. The relevance of these findings to humans is not clear at this time. Studies in
laboratory animals indicate limited evidence of renal malformations, resorptions, and
developmental delays following high levels of maternal exposure. The relevance of these
findings to humans is not clear at this time. Studies in laboratory animals indicate some
evidence of adverse effects on the liver, kidney, thyroid, and pituitary gland.
Cyclohexane:
Cyclohexane can cause eye, skin and mucous membrane irritation, CNS depressant and
narcosis at elevated concentrations. In experimental animals exposed to lethal
concentrations by inhalation or oral route, generalized vascular damage and degenerative
changes in the heart, lungs, liver, kidneys and brain were identified.
Cyclohexane has been the focus of substantial testing in laboratory animals. Cyclohexane
was not found to be genotoxic in several tests including unscheduled DNA synthesis,
bacterial and mammalian cell mutation assays, and in vivo chromosomal aberration. An
increase in chromosomal aberrations in bone marrow cells of rats exposed to cyclohexane

was reported in the 1980's. However, a careful re-evaluation of slides from this study by the
laboratory which conducted the study indicates these findings were in error, and that no
significant chromosomal effects were observed in animals exposed to cyclohexane. Findings
indicate long-term exposure to cyclohexane does not promote dermal tumorigenesis.
Naphthalene:
Studies in Humans Overexposed to Naphthalene:
Severe jaundice, neurotoxicity (kernicterus) and fatalities have been reported in young
children and infants as a result of hemolytic anemia from over-exposure to naphthalene.
Persons with Glucose 6-phosphate dehydrogenase (G6PD) deficiency are more prone to the
hemolytic effects of naphthalene. Adverse effects on the kidney have also been reported
from over-exposure to naphthalene but these effects are believed to be a consequence of
hemolytic anemia, and not a direct effect.
Studies in Laboratory Animals:
Hemolytic anemia has been observed in laboratory animals exposed to naphthalene.
Laboratory rodents exposed to naphthalene vapor for 2 years (lifetime studies) developed
non-neoplastic and neoplastic tumors and inflammatory lesions of the nasal and respiratory
tract. Cataracts and other adverse effects on the eye have been observed in laboratory
animals exposed to high levels of naphthalene. Findings from a large number of bacterial
and mammalian cell mutation assays have been negative. A few studies have shown
chromosomal effects (elevated levels of Sister Chromatid Exchange or chromosomal
aberrations) in vitro.
Styrene:
Neurological injury associated with chronic styrene exposure include distal hypesthesia,
decreased nerve conduction velocity, and altered psychomotor performance. These effects
did not occur with exposures to airborne concentrations that were less than 100 ppm.
Increased deaths from degenerative neurological disorders were found in a comprehensive
epidemiological study of Danish reinforced plastics workers. These workers were reported to
have a 2.5-fold increased risk for myeloid leukemia with clonal chromosome aberrations.
Also, there are several studies that suggest potential reproductive effects in humans and
experimental animals from overexposure to styrene. Styrene was not mutagenic in the
standard (liquid phase) Ames Salmonella/microsome assay, but was weakly positive when
tested in the vapor phase. IARC has listed styrene as possibly carcinogenic to humans
(Group 2B).
SECTION 12. ECOLOGICAL INFORMATION
Unleaded gasoline is potentially toxic to freshwater and saltwater ecosystems. Various
Ecotoxicity
grades of gasoline exhibited range of lethal toxicity (LC100) from 40 PPM to 100 PPM in
ambient stream water with Rainbow Trout (Salmo irideus). A 24-hour TLm (Median Toxic
Limit) was calculated to be 90 PPM with juvenile American Shad (Squalius cephalus). In
Bluegill Sunfish (Lepomis macrochirus), Grey Mullet (Chelon labrosus) and Gulf Menhaden (
Brevoortia patronus), gasoline exhibited a 96-hour LC50 of 8 PPM, 2 PPM, and 2 PPM,
respectively.
The aquatic toxicity of Methyl tertiary-Butyl Ether (MTBE) is considered to be relatively low. In
the crustacean Harpacticoid Copepods (Nitrocra spinipes), MTBE exhibited an LC50 (96-hour)
of 1,000 PPM to 10,000 PPM depending upon various water temperatures. In Bleak Fish (
Alburnus alburnus), MTBE exhibited an LC50 ( 24-hour) of 1,700 PPM and an LC50 (96-hour)
of 1,000 PPM at 10?C. In Golden Orfe Fish (Leuciscus idus melanotus), MTBE exhibited an
LC50 (48-hour) of 1,000 PPM and an LC100 of 2,000 PPM.

CITGO Gasolines, All Grades Unleaded
Avoid spilling gasoline. Spilled gasoline can result in environmental damage. Spilled gasoline
can penetrate soil and contaminate ground water. Although gasoline is biodegradable, it may
persist for prolonged time periods, particularly where oxygen levels are reduced. The
hydrocarbon components of gasoline are slightly soluble in water. Gasoline hydrocarbon
components do not readily dissolve in water but can be adsorbed to soils.
Gasoline contains components that are potentially toxic to freshwater and saltwater
ecosystems. It will normally float on water. The components of gasoline will evaporate
rapidly. Evaporated hydrocarbon components may contribute to atmospheric smog.
MTBE and other oxygenates are more soluble than other gasoline components. In addition,
oxygenates such as MTBE do not adsorb to soils, sediments or suspended particulate matter
as readily as other gasoline components. MTBE does not degrade as readily as other
gasoline components once in ground water or subsoil. MTBE is not expected to
bioconcentrate in the aquatic environment.
