The mechanism of neural toxicity has not been fully established; it is unclear whether this is a direct effect or is secondary to the production of free radicals. The broad substrate TDO in P. putida F1 is also capable of oxidizing and detoxifying trichloroethylene (TCE) to formic acid and glyoxylic acid, although trichloroethylene (TCE) is not used as a growth substrate by the strain.61,62, Mahmoud M. El-Halwagi, in Pollution Prevention through Process Integration, 1997, Toluene is to be removed from a wastewater stream. Rival captains Kane Williamson and Mohammad Rizwan paid rich tribute to New Zealand quick Neil Wagner who bowled with two broken toes to help the hosts win the tense opening test against Pakistan on Wednesday. 1993; Vrca et al. Partially cookies will be set by third parties. The results obtained in laboratory animals and solvent abusers logically raised the question of the potential ototoxicity of toluene in occupational settings. Toluene incurs no fuel excise tax, while other fuels are taxed at more than 40%, providing a greater profit margin for fuel suppliers. The cause of death was believed to be severe central nervous system depression. Main article: Responsible drug use The concept of responsible drug use is that a person can use recreational drugs with reduced or eliminated risk of negatively affecting other parts of one's life or other peoples lives. Toluene, an aromatic alkylbenzene hydrocarbon compound is often present in paints, lacquers, glues, and solvents. B O O K E D Today: 5 felonies, 9 misdemeanors, 0 infractions ← Yesterday This page notes the names of those processed by the Humboldt County Jail at the date and time indicated. where y1 and xj are the mass fractions of the toluene in the wastewater and the jth MSA, respectively. Hypothetical route of intoxication of the organ of Corti by organic solvents. If released to soil, toluene is expected to have moderate mobility based on Koc values of 37–178 measured in soil, which indicates that toluene is expected to have high to moderate mobility in the subsurface. Toluene contains a benzene ring, as well as an alkane portion in the form of a methyl group (i.e., CH3.) Three external MSAs are considered: air (S2) for stripping, activated carbon (S2) for adsorption, and a solvent extractant (S3). Maria K. Houtchens, in Clinical Neurotoxicology, 2009, Toluene (methylbenzene) is a natural substance of gasoline and crude oil. Toluene is used as an intoxicative inhalant in a manner unintended by manufacturers. Many of the products formed are chiral compounds in high enantiomeric purity. for paints, paint thinners, silicone sealants, many chemical reactants, rubber, printing ink, adhesives (glues), lacquers, leather tanners, and disinfectants.[19]. Exposure through inhalation is much more common. There is evidence that toluene causes not only myelin breakdown but also neural cell death. Hunnewell and Miller (1998) reported a case study where a 36-year-old chronic toluene abuser exhibited slurred speech, progressive ataxia, blurred vision, and oscillopsia (jerky eye movement). C6H5CH3 + H2 → C6H6 + CH4 The environmental and toxicological effects of toluene have been extensively studied. 3.19a). Toluene had also been used in the process of removing the cocaine from coca leaves in the production of Coca-Cola syrup. Incoordination, disequilibrium, confusion, and cognitive and memory deficits accompany these symptoms. Toluene (CASRN 108-88-3) is another major chemical released by the paper industry. Incoordination, disequilibrium, confusion, and cognitive and memory deficits accompany these symptoms. Toluene can relax users, cheer them up, and produce hallucinations. While the prevalence of toluene abuse in the United States is unknown, it is estimated that 10% to 15% of people have used the inhalant.22 Prolonged exposure to toluene vapors may result in multifocal leukoencephalopathy, with primary clinical manifestations of dementia, ataxia, brain-stem dysfunction, and corticospinal weakness. for its intoxicating effect . No drinking water supplies are impacted by the ELMCO release and the ELMCO release 150 lb. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Toxicological screening can detect toluene in the blood; hippuric acid analysis of urine is also helpful. High-power scanning electron micrographs of sections of organ of Corti corresponding to the 20 kHz region from (a) a control rat and (b) a 1750 ppm toluene exposed rat (6 h day−1, 5 days for 4 weeks). It has largely been replaced by a safer solvent; Xylol Xylene. Recreational drugs ass. Recreational use is by inhaling vapor from toluene, often in a group setting. Even though this is true, toluene should not be used recreationally or emitted irresponsibly due to the damage it causes to the nervous system (US EPA, 2005). 2017; 9:e1816. B. Pouyatos, ... L. Linda, in Comprehensive Toxicology, 2010. Volatilization from water surfaces is expected to be the dominant fate process based on the estimated Henry’s Law Constant. 3.19b). For 8000 operating hours per year, the annual operating cost of the system is $96,700/year. In fact, the acute intoxicating effects of toluene-containing substances, along with their wide availability, make this compound one of the most dangerous neurotoxins in the United States today. Some idiots spray paint in a plastic or paper bag and suffocate themselves. Jane W. Chan, in Clinical Neurotoxicology, 2009. Lesions of the basal ganglia are not thought to be caused by toluene exposure but may be present due to concomitant methanol exposure.7 In cases of recreational exposure, diagnosis is based on history and index of suspicion. The early reports of toluene toxicity in humans were made on solvent abusers, who were diagnosed with sensorineural hearing loss, the cortical evoked potential being generally more affected than brainstem evoked potential, indicating a probable disruption of central auditory pathways (Metrick and Brenner 1982; Ehyai and Freemon 1983; Poulsen and Jensen 1986). It is an industrial solvent and paint thinner. The remaining 14% was a "filler" of n-heptane, to reduce the octane to meet Formula One fuel restrictions. Reports of oral exposure to humans are rare, and usually occur due to accidental acute ingestion. The data for the candidate MSAs are given in Table 3.6. Toluene inhalation can lead to a toxic optic neuropathy. Toluene is a common solvent, e.g. Reports and studies have shown that toluene does not contribute to the formation of cancer in humans. 1999). 2003). 1983; Sullivan et al. 1999). It is a highly lipophilic white matter toxin resulting in loss of myelin in cerebral and cerebellar white matter, as well as in diffuse cerebral and cerebellar atrophy.20,21 Intentional abuse occurs through inhalation of toluene vapors from a rag soaked in paint or from a paper bag filled with paint or lacquer thinners, which contain toluene as principle component. People inhale toluene-containing products (e.g., paint thinner, contact cement, model glue, etc.) People “huff” or “sniff” paint, paint thinner, or glue in order to feel the euphoric effects of a large dose of toluene. We use cookies to help provide and enhance our service and tailor content and ads. Toluene would therefore not be expected to be found in the tissues of fish or wildlife as: (1) toluene contains no persistent functional groups (e.g., chlorine, bromine); (2) exposure would be expected to be low based on a low half-life in the environment; and (3) subsequent to exposure, trace levels of toluene would be rapidly metabolized by the liver (similar to what is seen with other organic compounds). Neuroimaging studies typically reveal diffuse atrophy and decreased gray–white differentiation. The PVECP abnormalities in these patients suggest that prolonged exposure to toluene can cause optic nerve damage. Ameno et al. The intoxication route of the organ of Corti is believed to be similar to styrene’s (Figure 10), that is, through the outer sulcus (Campo et al. Wagner played the last three days of the match with the broken toes after being hit by a Shaheen Afridi yorker in New Zealand's first innings at the Bay Oval. Inhalation of toluene can lead to a variety of neurologic manifestations, including ataxia, tremor, anosmia, sensorineural hearing loss, dementia, corticospinal tract dysfunction, and epileptic seizures (Hormes et al., 1986). In rat cardiac myocytes, 300 μ M toluene inhibited the sodium current ( I Na+ ) by 62%; this inhibition was voltage independent. Reproduced from Pierre Campo. Note: Toluene is used as an intoxicative inhalant in a manner not From: Encyclopedia of Soils in the Environment, 2005, S.R. N.L. standard for toluene for recreational use is 1.3 mg/L (1,300 µg/L) for surface water classified for both recreation and domestic water supply. It is also used for synthesis of benzene and other chemicals, including graphic pigments, paints, and solvents. 1994; Johnson and Canlon 1994; Pryor et al. Recreational use of glues, gasoline, and paints for their intoxicating effects is likely underestimated by many. 1. Toxicological characterization data for toluene. Toluene is a seven-carbon aromatic hydrocarbon compound that is a minor component (∼5%) of all gasoline. Cureus. Recreational Drugs 1. Acute toluene toxicity results in lightheadedness and euphoria. This study did not reveal significant effects of toluene level, of exposure duration, and of interactions between toluene and noise intensity. If released to air, the moderate vapor pressure predicts that toluene will exist solely as a vapor in the ambient atmosphere. As of 2007, 24 U.S. states had laws penalizing use, possession with intent to use, and/or distribution of such inhalants. Recreational use of glues, gasoline, and paints for their intoxicating effects is likely underestimated by many. Parales, K.-S. Ju, in Comprehensive Biotechnology (Third Edition), 2011, TDO has an extremely broad substrate range, catalyzing the oxidation of over 100 different substrates (reviewed in Refs. Most toluene is added to automobile or aviation gasoline mixtures (benzene⩾xylene⩾toluene) to increase octane ratings. for its intoxicating effect. Inhalation of toluene in low to moderate levels can cause tiredness, confusion, weakness, drunken-type actions, memory loss, nausea, loss of appetite, hearing loss, and colour vision loss. Acute toluene toxicity results in lightheadedness and euphoria. Honda solved this problem in their Formula One cars by routing the fuel lines through a heat exchanger, drawing energy from the water in the cooling system to heat the fuel. As an inhalant, toluene is known to have euphoric and dissociative effects. Inappropriate behavior, mood fluctuations, and nystagmus are also common. Dinitrotoluene is nitrated to trinitrotoluene. Figure 3.19a. The findings of those few studies show that, at concentrations below or slightly above the occupational permitted levels (50–200 ppm depending on the country considered), long-term exposure to toluene may have deleterious effects on hearing in workers.

The log octanol/water partition coefficient (Kow) is 2.73. Dinitrotoluene is needed for toluene diisocyanate, which is used to produce polyurethane foams. (1989) reported 15 deaths by oral ingestion between 1977 and 1986. Toluene can be used as an octane booster in gasoline fuels for internal combustion engines. These results suggest that toluene binds to cardiac Na + channels in the open state and unbinds either when channels move between inactivated states or from an inactivated to a closed state. Desai R, Shamim S, Patel The effects of inhalants range from central nervous system depression and intense euphoria to vivid hallucinogenic experiences such as internal and external hallucinations. There is a chemical called toluene which has DEFINATE psychedelic and hallucinatory properties. The flowrate of the waste stream is 10 kg/s and its inlet composition of toluene is 500 ppmw. prof. S. Zakharov, M.D., Ph.D. Charles University in Prague First Faculty of Medicine Department of Occupational Using a measured log Kow of 2.36, the USEPA’s EPI Suite computer program estimates both bioconcentration factor (BCF) and bioaccumulation factor (BAF) of 38. Both distortion product measures (Johnson and Canlon 1994) and histopathological analyses of cochleae (Lataye and Campo 1997; Loquet et al. Since toluene is often used as a highly dangerous recreational inhalant, there is increased legislation that is limiting its availability and increasing the need for toluene replacement alternatives. Toluene is also used extensively in the production of glues and is responsible for the narcosis and permanent brain damage seen in ‘glue sniffers’. PDF | On May 1, 2017, H. Cruz Tabuenca and others published Orthostatic tremor secondary to recreational use of solvents | Find, read and cite all the research you need on ResearchGate As an inhalant, toluene is known to have euphoric and dissociative effects. Volatilization of toluene from moist soil surfaces is expected to be an important fate process. Toluene at 86% by volume fuelled all the turbocharged engines in Formula One during the 1980s, first pioneered by the Honda team. Toluene is mainly used as a precursor to benzene via hydrodealkylation: When a psychoactive drug enters the user's body, it … Toluene is one of a group of fuels that have included in jet fuel surrogate blends. The flowrate of activated carbon is 0.015 kg/s. 360 with any questions that you may have. Inhalants refer to a broad range of household or industrial chemicals whose volatile vapors or gases are concentrated and inhaled into the lungs via the nose or mouth to produce a state of acute intoxication. ABR measurements in workers exposed to 50–100 ppm for 12–22 years were found to be affected, with a significant decrease in all wave amplitudes (Abbate et al. It was concluded that the threshold level for developing a hearing loss as a result of occupational toluene exposure might be above 50 ppm. Toluene at 100% can be used as a fuel for both two-stroke and four-stroke engines; however, due to the density of the fuel and other factors, the fuel does not vaporize easily unless preheated to 70 °C (158 °F). Recreational use of glues, gasoline, and paints for their intoxicating effects is likely underestimated by many. When oxidized it yields benzaldehyde and benzoic acid, two important intermediates. Toluene has a molecular weight of 92.14 g mol−1. Table 6.21. Accurate exposure levels were not available, but the concentrations inhaled by chronic abusers were estimated to range from 4000 to 12 000 ppm (Gospe et al. Since air is the least expensive, it will be used to remove all the load to its right (0.0045 kg toluene/s, as can be seen from Fig. Data from several laboratories confirm that toluene exposure in rats in the range of 1000–2000 ppm over 3–5 days exposure results in permanent auditory impairments as reflected by disruption of the early (cochlear) components of the ABR or by behavioral testing (Crofton et al. Some evidence shows toluene may also alter neuronal response to certain neurotransmitters.6,7. Axonal swelling and thinning of the myelin sheath of peripheral nerves have been demonstrated on histopathological studies.59, R.E. Patients present with diffuse cerebral edema after recreational drug use for a variety of reasons, and generally it indicates a poor prognosis. Toluene has also been used as a coolant for its good heat transfer capabilities in sodium cold traps used in nuclear reactor system loops. In the 1980s, modern neuroimaging began to be regularly applied to the study of chronic toluene abusers. Use the pinch diagram to determine the minimum operating cost of the MEN. Clough, in Encyclopedia of Toxicology (Third Edition), 2014. Toluene intoxication lasts longer than intoxication from assorted other inhalants. Toluene is needed for dinitrotoluene. It readily crosses the blood–brain barrier (BBB) and has an affinity for white matter. Aside from removal of the toxic source, no direct treatment exists for toluene toxicity and care is supportive only. Inhaling high levels of toluene in a short time may cause light-headedness, nausea, or sleepine… Figure 10. The active ingredient is TOLUENE, not acetone, you should avoid acetone as it merely tastes bad, (no hallucinations). Industrial emissions, car exhausts, and cigarette smoke (cigarettes contain about 80 μg/cigarette) are three large sources of atmospheric toluene. • Toluene inhibits excitatory ion channels including the nicotinic acetylcholine receptors (nAChRs) and N-methyl-D-aspartate (NMDA) glutamate. Exposure to toluene can occur through air, water, soil, and groundwater, but almost all of the toluene released as emissions is dispersed into the air. A study in France on workers chronically exposed to toluene fumes reported leukopenia and neutropenia. Blood toluene levels may also be used. The extent of toluene substitution has not been determined. Toluene Market Size, Industry Analysis Report, Regional Outlook, Application Development Potential, Price Trend, Competitive Market Share & Forecast, 2020 - 2026 Toluene Market size demand is mainly driven by growth in applications across industries petrochemical, building & construction, oil & gas, paints, resins, printing, leather, pharmaceuticals and rubber industry. He recovered after 36 hours of supportive care. Screening external MSAs for the toluene-removal example. Spitz, C.M. 1999) from toluene-exposed animals confirmed that the outer hair cells are especially vulnerable to toluene (Figure 11). Leukoencephalopathy of toluene abuse is evident on MRI scans and on postmortem examinations.23. Conversion factors for toluene in air are as follows: 1 mg m−3 = 0.27 ppm; and 1 ppm = 3.77 mg m−3. In addition to the synthesis of benzene and xylene, toluene is a feedstock for toluene diisocyanate (used in the manufacture of polyurethane foam), trinitrotoluene (the explosive, TNT), and a number of synthetic drugs. The visual prognosis and the PVECP changes were identical in both eyes of all patients. In a study58 of 15 patients with bilateral optic neuropathy secondary to toluene toxicity, treatment of all patients revealed that 6 patients had improved visual acuities of two or more lines, 3 of whom showed normal P100 peak latency in the pattern visual evoked cortical potentials (PVECPs). Toluene can be used to break open red blood cells in order to extract hemoglobin in biochemistry experiments. Toluene is used as a cement for fine polystyrene kits (by dissolving and then fusing surfaces) as it can be applied very precisely by brush and contains none of the bulk of an adhesive. Toluene is an excellent organic solvent and is used extensively in the manufacture of benzene derivatives, caprolactam, saccharin, medicines, dyes, perfumes, TNT, toluenediisocyanates (polyurethane resins), toluene sulfonates (detergents); as a solvent for scintillation counting; in paints and coatings, gums, resins, rubber; and as a diluent and thinner in nitrocellulose lacquers, plastic toys, and model airplanes. Toluene is used as a jet fuel surrogate for its content of aromatic compounds. Gasoline, containing up to 7% toluene by weight, represents the most significant source of toluene used in this country.8 Myriad accounts of cases of acute and chronic toluene-induced encephalopathy exist and occur in the setting of accidental or intentional inhalation. High concentrations (10,000–30,000 ppm) can cause narcosis and death. Trinitrotoluene explosive synthesis requires toluene. Toluene has also been shown to be ototoxic in laboratory animals at much lower concentrations. TDO is one of many enzymes with the ability to convert indole to the blue dye indigo, and this property has facilitated the cloning of the dioxygenase genes and the isolation of mutant strains. Toluene, a.k.a. Adriaen Brouwer, The Smokers (1636) Edgar Degas, L'Absinthe (1876) Recreational drug use is the use of a psychoactive drug to induce an altered state of consciousness, by modifying the perceptions, feelings, and emotions of the user. Nicholas P. Cheremisinoff, Paul E. Rosenfeld, in Handbook of Pollution Prevention and Cleaner Production, 2010. The acute CNS effects of toluene reverse quickly after cessation of the exposure. Both the OSHA and ACGIH had labeled it as a noncarcinogen. In 2013, worldwide sales of toluene amounted to about 24.5 billion US-dollars. Toluene may volatilize from dry soil surfaces based on the moderate vapor pressure. Repeated exposures, however, can lead to chronic symptoms of intention tremor, motor incoordination, and cognitive deficits. Exposure levels were not given, but the average urinary excretion of hippuric acid, a metabolite of toluene, was given at 4 g/l compared to the normal level of 0.6 g/l (Sandmeyer, 1989). The EPA has labeled toluene as an HAP and a toxic substance. Copyright © 2021 Phú Bình. 1997). The rewarding effects of toluene, like other drugs, are likely mediated by its 1996, 1997; Morata et al.
