- Health Effects: Acute exposure to cholinesterase inhibitors can cause a cholinergic crisis characterized by severe nausea/vomiting, salivation, sweating, bradycardia, hypotension, collapse, and convulsions. Increasing muscle weakness is a possibility and may result in death if respiratory muscles are involved. Accumulation of ACh at motor nerves causes overstimulation of nicotinic expression at the neuromuscular junction. When this occurs symptoms such as muscle weakness, fatigue, muscle cramps, fasciculation, and paralysis can be seen. When there is an accumulation of ACh at autonomic ganglia this causes overstimulation of nicotinic expression in the sympathetic system. Symptoms associated with this are hypertension, and hypoglycemia. Overstimulation of nicotinic acetylcholine receptors in the central nervous system, due to accumulation of ACh, results in anxiety, headache, convulsions, ataxia, depression of respiration and circulation, tremor, general weakness, and potentially coma. When there is expression of muscarinic overstimulation due to excess acetylcholine at muscarinic acetylcholine receptors symptoms of visual disturbances, tightness in chest, wheezing due to bronchoconstriction, incre Source: Toxin and Toxin Target Database (T3DB)

- Toxicity Summary: IDENTIFICATION AND USE: Toluene is a colorless liquid. It is not registered for current pesticide use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. Toluene is a component of gasoline, paints, inks, lacquers, paint thinners, adhesives, fingernail polish, cleaning agents, and rubber. BTX (a mixture of benzene, toluene, and xylene) is added to gasoline to improve octane ratings. Toluene is used to produce benzene, trinitrotoluene (TNT), nylon, plastics, and polyurethanes. It is also used in production of drugs of abuse. Toluene is a favorite of solvent abusers, who intentionally inhale high concentrations to achieve a euphoric effect. HUMAN EXPOSURE AND TOXICITY: Eye and upper airway irritation occurred after a 6.5 hr exposure to an air level of 100 ppm (377 mg/cu m) toluene, and lacrymation was seen at 500 mg/cu m. Volunteers exposed to 100 ppm (377 mg/cu m) toluene for 6 hr/day for four days suffered from subjective complaints of headache, dizziness and a sensation of intoxication. In subjects exposed to 750 mg/cu m for 8 hr, fatigue, muscular weakness, confusion, impaired c Source: Hazardous Substances Data Bank (HSDB)
- Toxicity Summary: Toluene is a cholinesterase or acetylcholinesterase (AChE) inhibitor. A cholinesterase inhibitor (or 'anticholinesterase') suppresses the action of acetylcholinesterase. Because of its essential function, chemicals that interfere with the action of acetylcholinesterase are potent neurotoxins, causing excessive salivation and eye-watering in low doses, followed by muscle spasms and ultimately death. Nerve gases and many substances used in insecticides have been shown to act by binding a serine in the active site of acetylcholine esterase, inhibiting the enzyme completely. Acetylcholine esterase breaks down the neurotransmitter acetylcholine, which is released at nerve and muscle junctions, in order to allow the muscle or organ to relax. The result of acetylcholine esterase inhibition is that acetylcholine builds up and continues to act so that any nerve impulses are continually transmitted and muscle contractions do not stop. Among the most common acetylcholinesterase inhibitors are phosphorus-based compounds, which are designed to bind to the active site of the enzyme. The structural requirements are a phosphorus atom bearing two lipophilic groups, a leaving group (such as a halide Source: Toxin and Toxin Target Database (T3DB)
- Environmental Bioconcentration: The BCF of toluene in eels (Anguilla japonica) was reported as 13(1) and the BCF in golden ide (Leuciscus idus melanotus) was reported as 90(2). According to a classification scheme(3), these BCF values suggest the potential for bioconcentration in aquatic organisms is low to moderate(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), Koc values of 37-178 measured in soil(2,3) indicate that toluene is expected to have high to moderate mobility in soil(SRC). Volatilization of toluene from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 6.64X10-3 atm-cu m/mole(4). Toluene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 28.4 mm Hg at 25 °C(5). Complete biodegradation of toluene was observed in lab microcosm tests during a 40 hour incubation period using soils previously exposed to toluene(6). The biodegradation half-life in various soils was reported as several hours to 71 days(7). These tests suggest that biodegradation is an important environmental fate process in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), a Koc value of 166 measured in lake sediment(2) indicates that toluene is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 6.64X10-3 atm-cu m/mole(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 1 hour and 4 days, respectively(SRC). According to a classification scheme(5), BCF values of 13(6) and 90(7) measured in fish suggest the potential for bioconcentration in aquatic organisms is low to moderate(SRC). The half-life of toluene in aerobic and anaerobic water was reported as 4 and 56 days(8), respectively, suggesting that biodegradation is an important environmental fate process in water(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), toluene, which has a vapor pressure of 28.4 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase toluene is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals, nitrate radicals and ozone molecules(SRC). The half-life for the reaction with hydroxyl radicals is estimated to be 2 days(SRC), calculated from its rate constant of 5.93X10-12 cu cm/molecule-sec at 25 °C(3). The half-life for the nighttime reaction with nitrate radicals is estimated as 491 days(SRC) calculated from its rate constant of 6.8X10-17 cu cm/molecule-sec at 25 °C(4). The half-life for the reaction with ozone is estimated as 27,950 days(SRC) calculated from its rate constant of 4.1X10-22 cu cm/molecule-sec at 25 °C(4). Toluene does not absorb light at wavelengths >290 nm(5) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC). Source: Hazardous Substances Data Bank (HSDB)
