Leidel NA, Busch KA, Lynch JR (1977). Thus special precautions are often necessary to prevent or limit worker exposure in these situations, and they frequently involve the use of personal protective equipment. 1980). 1980). Scand J Work Environ Health 1:178-183. Copenhagen, Denmark: World Health Organization and Nordic Council of Ministers, pp. You will be subject to the destination website's privacy policy when you follow the link. 78-181. Chloroethanes: review of toxicity. 5th edition. Correspondence between the two systems of nomenclature is not exact, but the categories produced by these two workshops do help clarify the chronic effects of solvents on the CNS. Developmental and adult/ageing neurotoxicity is an area needing alternative methods for chemical risk assessment. Several venomous snakes and their predators have evolved resistance to -neurotoxins . Volunteers exposed for two 4-hr periods at average concentrations of 110 ppm showed statistically significant decreases in performance ability on tests of perception, reaction time, memory, and manual dexterity compared with their performance ability before exposure (Salvini et al. 111-133. Our intention is to provide anyone who needs it with ready access to the information in these documents; we welcome suggestions concerning their content, style, and distribution. Work Environ Health 11:86-93. The test scores of the exposed workers were significantly lower (p<0.004) than those of the unexposed control workers (Valciukas et al. 1980). Ciguatoxins are a group of lipid-soluble molecules that act on tetrodotoxin-sensitive voltage-gated Na + channels in nerve and muscle, leading to increased Na + permeability at rest and membrane depolarization. Today, chlorpyrifos is classified as "very highly toxic" to birds and freshwater fish, and "moderately toxic" to mammals, but it is still used widely in agriculture on food and non-food crops, in. Thus it appears that acute ethanol ingestion raises blood toluene and xylene concentrations through competition for metabolism, whereas chronic ethanol ingestion induces solvent-metabolizing enzymes and thereby lowers blood solvent concentrations. NIOSH (1977d). Metabolism usually results in the detoxication of the organic solvent through formation of water-soluble compounds that are excreted through urine or bile (Toftgard and Gustafsson 1980). Baker EL, Smith T, Landrigan P (1985). 1980). A complete respiratory protection program should include (1) selection of respirators approved by the Mine Safety and Health Administration (MSHA) and NIOSH, (2) regular training of personnel, (3) fit testing, (4) periodic environmental monitoring, and (5) maintenance, inspection, and cleaning of equipment. In: Spencer P, Schaumburg H, eds. The ACGIH designation C indicates the concentration that should not be exceeded during any part of the working exposure.The ACGIH designation A2indicates an industrial substance suspected of having carcinogenic potential for humans. Neurobehavioral performance tests of CNS function (i.e., Block Design and Embedded Figures) were administered to 55 shipyard painters, 95% of whom had more than 10 years of work experience that involved exposure to methyl isobutyl ketone, perchloroethylene, xylene, ethylene glycol, and mineral spirits. The brain-specific S100 protein in small cerebral stab wounds in the rat. These workers exhibited a statistically significant incidence (p<0.001) of Type 1 subjective psychiatric complaints (e.g., memory problems, headache, fatigability) when compared with unexposed matched reference groups (Elofsson et al. Toluene is used in the manufacture of chemicals and in paints and coatings as a solvent (NIOSH 1973a). The exposed workers with indications of brain dysfunction were among the more heavily exposed subjects, indicating a possible relationship between exposure level and effect. Neurotoxic effects of organic solvents in exposed workers: an occupational, neuropsychological, and neurological investigation. NIOSH (1984b). 1978). Arch Neurol 32:209-218. 1974). The potential exposure of each subject was graded as low, intermediate, or high, based on workplace measurements of the solvents and information provided by the subject or the employer (Seppalainen et al. Approximately 9.8 million workers are potentially exposed to organic solvents. New England J Occup Med 285:82-85. *NIOSH recommendations for time-weighted averages (TWAs) are based on exposures of up to 10 hr per workday unless otherwise noted. Symptoms include: weakness in the extremities; tingling sensations or numbness; memory loss; loss of vision and/or intellect; uncontrollable obsessive and/or compulsive behaviors; delusions;. II. Psychological picture of manifest and latent carbon disulphide poisoning. 1976). Table 3 lists types of respirators recommended for protection against organic solvents with poor warning characteristics or organic solvents for which effective adsorption-filtering media are unavailable. To date, most experimental animal studies with organic solvents have been conducted to determine their acute neurotoxic effects on the . Br J Ind Med 28:374-381. For example, n-hexane and methyl n-butyl ketone (solvents that produce peripheral neuropathies in exposed workers [Herskowitz et al. The nervous system effects of exposure to organic solvents can lead to significant morbidity and increased risk of accidental injury, both on the job and away from work. 1979), and a 28% increase was reported in a study using xylene (Riihimaki et al. brain tumors breathing difficulties convulsions depression epileptic seizures fatigue headaches and migraines hearing loss heart palpitations insomnia joint pain loss of taste memory loss nausea numbness slurred speech tinnitus vertigo vision loss weight gain and obesity Mind Lab Pro WHAT'S THE BEST BRAIN SUPPLEMENT? Exhaust ventilation systems for quality control laboratories or laboratories where samples are prepared for analyses should be designed for adequate capture and containment of organic solvent vapors. Behavioral effects of exposure to solvents. Hanninen H (1971). Van Nostrands scientific encyclopedia. Special occupational hazard review with control recommendations. Table 2. NIOSH (1983a). Baltimore, MD: Williams and Wilkins, pp. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Neurotoxicology 2:659-673. Director, National Institute for Appendix A lists those chemicals and mixtures with NIOSH RELs, OSHA PELs, and ACGIH TLVs (ACGIH 1986). Centers for Disease Control and Prevention. An animal model of the mechanism of pathogenesis would lead to more accurate methods for predicting the neurotoxicity of organic solvents. Lead, plant product (drinking alcohol), atomic number 25 salt, gas (NO), neurolysin (e.g. Workers should also be given access to relevant exposure and medical records (29 CFR 1910.20). 1978). Psycho-physiological functions. Direct skin contact with organic solvents should be prevented through the proper use of solvent-resistant gloves, aprons, boots, or entire work suits, depending on the nature and extent of the hazard. 1980) has been associated with neuropsychiatric (Type 1*) and neuropsychologic (Type 2*) effects (Bardodej and Vyskocil 1956; Grandjean et al. 1981, 1985). [return to table], Table 4. Neurotoxins ; Cytotoxins ; Hemotoxins ; Toxins are categorized based on the system within the body they affect. Black widow spiders use neurotoxins. neurotoxicological. Browning E (1965). Chronic animal studies with a limited number of organic solvents support the evidence for peripheral neuropathy and mild toxic encephalopathy in solvent-exposed workers. Spinach is near the top of the Dirty Dozen produce list, as it contains more pesticide residue by weight than any other fruits and vegetables, with an average of seven different pesticides in each sample. Manual of analytical methods. The use of GH secretagogues as a form . 1979). Lazar R, Ho S, Melen O, Daghestani A (1983). This information should include any available results from workplace sampling and a description of any protective devices or equipment the worker may be required to use. NIOSH (1977a). Metabolism in the liver generally consists of oxidative reactions catalyzed by the cytochrome P-450 mixed-function oxidase system followed by conjugation with glucuronic acid, sulfuric acid, glutathione, or glycine. 2048-2049. 1-39. Athletes and bodybuilders often use them in an attempt to stimulate the release of growth hormone from the pituitary gland, which may increase muscle mass, reduce body fat, and improve physical performance. This result was measured by ratings of sleepiness, physical and mental tiredness, and general good health for exposed workers compared with unexposed control workers or controls exposed to low levels of styrene. Waldron HA, Cherry N, Johnston JD (1983). Scand J Work Environ Health 4:73-85. NIOSH (1973b). Scand J Work Environ Health 11 (Supplement 1):53-60. 1971; Spencer et al. Symptoms include: weakness in the extremities; tingling sensations or numbness; memory loss; loss of vision and/or intellect; uncontrollable obsessive and/or compulsive behaviors; delusions; headaches; cognitive and behavioral issues; and sexual dysfunction. This condition has been reported in another study in connection with diffuse cerebral atrophy (Willanger and Klee 1966). When male Wistar rats inhaled 50 to 100 ppm thinner containing 60% toluene over a 10-or 20-day period for 15 min/day, they developed alterations of neuronal structures in the CNS (nucleolus, perichromatin fibrils, and ribosomes) (Vazquez-Nin et al. New York, NY: Van Nostrand Reinhold Company, pp. Gamberale F, Hultengren M (1973). When workers exposed to styrene or methylene chloride were evaluated for blood solvent levels, a statistically significant correlation (p<0.05) existed between the elevation of solvent level in the blood at the end of the workshift and deterioration in mood during the workshift. Seppalainen AM, Husman K, Martenson C (1978). Time course of electrophysiological findings for patients with solvent poisoning. Exposures at the STEL should not be longer than 15 min and should not be repeated more than four times per day. Seppalainen AM, Antti-Poika M (1983). The condition is characterized by global deterioration in intellectual and memory functions (dementia) that may be irreversible, or at best, only poorly reversible. 77-151. These metabolites are capable of covalently binding to essential macromolecules (e.g., proteins, RNA, and DNA) and producing toxic effects (Toftgard and Gustafsson 1980; WHO 1985). Special consideration should be given to exposures that may occur during the release of these compounds from pressurized sampling containers. Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Center for Disease Control, National Institute for Occupational Safety and Health. A medical and work history should be taken initially and updated periodically. 1977, 1982). More than 1,000 chemicals are known to have neurotoxic effects in animals. NIOSH (1977c). Where closed systems cannot be used, local exhaust ventilation should be provided to direct vapors away from workers and to prevent the recirculation of contaminated exhaust air. EEG abnormalities persisted for 3 to 9 years in 42% of a group of patients diagnosed as having chronic solvent intoxication after occupational exposure (Seppalainen and Antti-Poika 1983). In male Wistar rats, a 23-day continuous inhalation exposure to 750 ppm MEK and 225 ppm MBK potentiated the neurotoxicity of MBK, whereas a 2-month continuous exposure to 400 ppm MBK alone did not (Abdel-Rahman et al. Visuomotor performance declined with increasing duration of solvent exposure in a statistically significant manner (p<0.001). Trichloroethylene. 1976; Bignami and Dahl 1974), were shown following inhalation of 60 parts per million (ppm) of trichloroethylene, 60 ppm of perchloroethylene, or 350 ppm of methylene chloride, or following daily ethanol ingestion of 11.7 grams per kilogram (g/kg) of body weight. Solvent elimination occurs through exhalation of the parent compound in expired air or through urinary or biliary excretion of water-soluble metabolites or of unchanged solvent. However, metabolism may also produce reactive intermediate metabolites that are more toxic than the parent compound. Scand J Work Environ Health 5:232-248. Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. NIOSH (1978d). The problem of trichloroethylene in occupational medicine. Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Center for Disease Control, National Institute for Occupational Safety and Health, DHEW (NIOSH) Publication No. Willanger R, Klee A (1966). 18th edition. 2nd edition. 1980). Compared with an unexposed reference population, the exposed workers exhibited more symptoms of personality and mood change (Type 2A) and a statistically significant increase (p<0.05) in unspecified emotional changes. Dennis Defoe and Alok Argwaral for their advice and encouragement. Characteristics Training is to be provided at the time of initial assignment and whenever a new chemical hazard is introduced into the work area. Neurobehavioral changes among shipyard painters exposed to solvents. Symptoms, which may appear immediately after exposure or be delayed, may include: Limb weakness or numbness Loss of memory, vision, and/or intellect Headache Cognitive and behavioral problems Sexual dysfunction Individuals with certain disorders may be especially vulnerable to neurotoxicants. NIOSH considers the PELs, RELs, and TLVs for the specific organic solvents found in the workplace to be upper boundaries of exposure. The acute toxic effects of solvent inhalation noted in animals reflect those seen in humansthat is, narcosis, anesthesia, CNS depression, respiratory arrest, unconsciousness, and death (Browning 1965). NIOSH (1978b). The psychologic examination consisted of a battery of psychometric tests for examining workers with suspected toxic encephalopathy. The further development of a standardized approach to describing the effects of chronic solvent exposure on the CNS will aid in the interpretation of studies in different parts of the world (Waldron 1986). They help us to know which pages are the most and least popular and see how visitors move around the site. 1983; King et al. CRC Crit Rev Toxicol 7:279-356. Also, people with certain types of disorders can be more vulnerable to these substances. Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, DHHS (NIOSH) Publication No. Engstrom K, Husman K, Riihimaki V (1977). Mean breathing zone concentrations for these four solvents were below the Finnish threshold limit values (150, 200, 200, and 100 ppm, respectively) and below the NIOSH RELs (none, 100, 55, and 100 ppm, respectively) (NIOSH 1973a, 1975, 1977c)or in the absence of a REL, below the OSHA PEL (butyl acetate, 150 ppm) (29 CFR 1910.1000). Haglid K, Karlsson JE, Kyrklund T, Rosengren L, Wikgren A, Kjellstrand P (1985). 1981 found that neurologic status and degree of neuropsychologic impairment were unchanged in 26 former house painters who had been diagnosed 2 years previously as having chronic toxic encephalopathy (cerebral atrophy and/or intellectual impairment) following a mean solvent exposure of 28 years. Neurobehav Toxicol 2:25-30. Criteria for a recommended standard: occupational exposure to carbon disulfide. The term organic solvents refers to a group of volatile compounds or mixtures that are relatively stable chemically and that exist in the liquid state at temperatures of approximately 0 to 250C (32 to 482F). Effects of short-term m-xylene exposure and physical exercise on the central nervous system. Following absorption, organic solvents undergo biotransformation (which occurs primarily in the liver), or they accumulate in lipid-rich tissues such as those of the nervous system (WHO 1985; Bergman 1983). 1955; Lilis et al. Electrophysiological findings in rats with experimental carbon disulphide neuropathy. The manual discusses how to determine the need for exposure measurements and how to select sampling times. [return to table] NIOSH is also concerned about those organic solvents for which only neurotoxic effects have been reported. Sodium caseinate: This type of protein is common in dairy products and junk food. 2,5-Hexanedione, a metabolic product of n-hexane (DiVincenzo et al. Like n-hexane, MBK is also metabolized to 2,5-hexanedione (DiVincenzo et al. If you do not allow these cookies we will not know when you have visited our site, and will not be able to monitor its performance. Br Med J 283:663-665. 1985). The effects of ethanol on blood toluene concentrations. Studies of various groups of solvent-exposed workers have demonstrated changes in neurophysiologic parameters measured by electroencephalograms (EEGs) and tests of peripheral nerve function. We take your privacy seriously. Psychophysiological functions. Degeneration in central and peripheral nervous systems produced by pure n-hexane: an experimental study. On the basis of the identified adverse health effects of solvent exposure, the National Institute for Occupational Safety and Health (NIOSH) recommends that employers use engineering controls, personal protective equipment and clothing, and worker education programs to reduce exposure to organic solventsat least to the concentrations specified in existing Occupational Safety and Health Administration (OSHA) permissible exposure limits (PELs), or to NIOSH recommended exposure limits (RELs) or the American Conference of Governmental Industrial Hygienists (ACGIH) threshold limit values (TLVs) if they provide a greater degree of protection. One study involved 30 workers who were exposed for a mean of 17 years to jet fuel composed of organic hydrocarbons. NIOSH (1978c). Psychological functions. Each PEL is determined as an 8-hr time-weighted average (TWA) concentration, and it is based on the 1968 threshold limit value TLV of the American Conference of Governmental Industrial Hygienists (ACGIH) (ACGIH 1968) for a specific organic solvent. Synthetic organic chemicals. *** Baker and Seppalainen 1986. 1980a) and in individuals who abusively inhaled the compound (Altenkirch et al. Cincinnati , OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Center for Disease Control, National Institute for Occupational Safety and Health, DHEW (NIOSH) Publication No. Inland Taipan. Criteria for a recommended standard: occupational exposure to refined petroleum solvents. Am J Ind Med 8:207-217. The individual test profiles revealed that 14% of the exposed workers and none of the reference group workers had definite indications of brain dysfunction (toxic encephalopathy), as indicated by significant deviation (>l standard deviation) from expected values in two or more of the psychometric variables tested. Over 70 neurotoxins are commonly used as food additives. Spencer P, Couri D, Schaumburg H (1980a). Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data. Many venomous snakes have alpha-neurotoxins (-neurotoxins) in their venom. Toluene exposure: II. Metabolic interaction between m-xylene and ethanol. Current intelligence bulletin 39. A cross-sectional study of the effects of chronic exposure (mean of 18 years) to solvents in the paint industry showed statistically significant differences (p<0.05) in the EEG activity of the exposed group when compared with unexposed workers (Orbaek et al. Cincinnati , OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Center for Disease Control, National Institute for Occupational Safety and Health, DHEW (NIOSH) Publication No. Multifocal central nervous system damage caused by toluene abuse. Some of the widely used neurotoxic monomers and their effect on the nervous system are listed in Table 3. The Occupational Safety and Health Administration (OSHA) has promulgated permissible exposure limits (PELs) for occupational exposure to some of the chemicals and mixtures that are used as organic solvents (29 CFR* 1910.1000). 846-855. Qualified industrial hygiene personnel should make initial and periodic surveys of worker exposure. -k-lj--kl. Studies have demonstrated that these effects can persist for months to years after removal of workers from solvent exposure. NIOSH estimates that 9.8 million workers are potentially exposed to organic solvents used in such products as paints, adhesives, glues, coatings, and degreasing/cleaning agents, and in the production of dyes, polymers, plastics, textiles, printing inks, agricultural products, and pharmaceuticals. Chronic effects of trichloroethylene exposure. Toxins in nature have two primary functions: Predation - killing a potential meal (for example, spiders, wasps, jellyfish and sea anemones). The neurotoxicity of industrial solvents: a review of the literature. These effects include CNS depression, psychomotor impairment, and narcosis. Cincinnati, OH: U. S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, DHHS (NIOSH) Publication No. These effects include disorders is characterized by reversible subjective symptoms (fatigability, irritability, and memory impairment), sustained changes in personality or mood (emotional instability and diminished impulse control and motivation), and impaired intellectual function (decreased concentration ability, memory, and learning ability). n-Hexane neuropathy. No precise determination has been made of the excess risk of neurotoxic effects in workers exposed to specific concentrations of organic solvents, but the probability of developing such effects would be decreased by reducing exposure.
