Benzene and ethanol additive inhibition of rabbit reticulocyte heme and protein synthesis.
The haeme and protein synthesis were measured in vitro. The protein synthesis inhibitions were: benzene 29.9%, ethanol 20.5%, both 42.3%, haeme synthesis: benzene 26.6%, ethanol 25.5%, both 39.7%. It is suggested that it might be prudent for workers exposed to benzene to limit their intake of alcohol.

Association between renal function tests and pentachlorophenol exposure.
Report on studies in 18 workers at a wood treatment plant. Blood pentachlorophenol levels averaged 5.1ppm, falling to 2.2ppm during a 20-day vacation. Creatinine clearance and phosphorus reabsorption values were low before vacation, but recovered during the non-exposure period. Pentachlorophenol exposure appeared to reduce both glomerular filtration rate and tubular function reversibly.

Effects of perchloroethylene/drug interaction on behaviour and neurological function.
This study attempted to determine the degree of hazard if the effect of a central nervous system depressant is added to the effect of perchloroethylene (PCE) exposure. There appeared to be no decreases in neurological or behavioural performance due to the combined effects of the substances. Six men and six women volunteers were exposed to PCE vapour and ethanol (as vodka) or diazepam was added. Several neurological and behavioural tests were given at peak blood levels of the drugs. There were decreases in performances with the drugs alone.

Formaldehyde-p-tert-butylphenol resins and p-tert-butylphenol in occupational medicine
Les résines formaldéhyde-paratertiaire butylphénol et le paratertiaire butylphénol en médecine du travail. [in French]
Report of a study of the role of formaldehyde-p-tert-butylphenol resins and their starting materials in allergic disorders in the footwear industry and in shoe repair workers. Preventive measures include: modification of concentration, gluing to be carried out in isolated premises, precautions in handling, use of impermeable aprons, personal hygiene, worker information. A group allergy may exist between p-tert-butylphenol and the resin itself, although each product individually is capable of producing sensitisation; p-tert-butylphenol, in the manufacturing stage and in the chemical industry, can cause achromia which can be reproduced in animal experiments.

Poisoning by pentachlorophenol or its sodium salt in treatment of wood by soaking
Intoxication au pentachlorophénol ou à son sel de sodium dans le traitement des bois par la technique de trempage. [in French]
MD thesis. General review of wood. Physical, chemical and biological data on pentachlorophenol; determination in biological media; methods of use. Literature survey of animal experiments to establish the minimum lethal dose, route of entry (mainly the skin), maximum permissible concentrations, and lesions produced (liver, kidney, lung, CNS). The physiopathology is not fully understood. Description of 13 cases of poisoning in 1952-1970 and a new fatal case in 1973. This rare but serious event involves a febrile course characterised by profuse sweating preceding the rise in temperature, the possibility of hepatonephritis, and rapid progression. Preventive measures can be directed at labelling and storage but the medical and personal protective aspects are the most important.

Toxicology of higher aliphatic alcohol acrylates
K toksikologii ėfirov akrilovoj kisloty i vysših alifatičeskih spirtov [in Russian]
Animal experiments to determine the toxicity of heptyl acrylate (HA) and nonyl acrylate (NA), used in the plastics industry. HA is much more toxic than the (presumed) hydrolysis products, acrylic acid and heptyl alcohol, and is extremely toxic on acute administration. Chronic exposure to HA and NA affects the oxidation-reduction processes and produces nervous, renal and myocardial toxicity. Proposed TLV for these substances, on the basis of acute and chronic exposure tests: 1mg/m3.

Chlorophenols cause skin disorders and headache in sawmills
Klorfenoler i sågverk ger hudskador och huvudvärk [in Swedish]
Chlorophenol salts used to preserve sawn wood are a source of skin irritation when they contain impurities such as dibenzodioxins and dibenzofurans, which are formed by the action of light or heat. Vapours and dust from the treated wood are also irritating for the respiratory tract and have neurotoxic effects. Highly toxic impurities precipitate to the bottom of the dipping tanks. Replacement of chlorophenols by difluorides, which are easier to monitor, the use of salts containing less impurities, and information of personnel of the hazards and suitable preventive measures are recommended.

The benzenediols: catechol, resorcinol and hydroquinone - A review of the industrial toxicology and curent industrial exposure limits.
This article reviews the acute animal toxicity data (oral LD50, skin penetration LD50, eye irritation, primary skin irritation, inhalation) for catechol, resorcinol and phenol, and studies on plant exposures to resorcinol and hydroquinone. Threshold limit values are discussed. The data suggest a TLV for catechol close to that for phenol (5ppm). Resorcinol is significantly less toxic than phenol, and a TLV of at least 10ppm, possibly 20ppm or higher, is suggested. The TLV for hydroquinone (2mg/m3) appears appropriate. Appendix: physical properties of the 3 benzenediols.

Neuropsychiatric disorders following phenol intoxication
Neuropsychiatrische Störungen nach Phenol-Intoxikation [in German]
Case report (circumstances of accident, acute symptoms, late symptoms, psychological observations, diagnostic conclusions) and discussion of the results in the context of the literature. A 30-year-old engineer in the chemical industry had intensive skin absorption and inhalation of phenol after overturning of a container. After discharge from a week's hospital treatment he showed characteristic symptoms of chronic phenol poisoning (loss of appetite, headache after effort, fatigue, severe insomnia), although some typical symptoms of acute phenol poisoning (liver and kidney damage, cerebral convulsions) were absent. Other symptoms of central nervous disturbance (behavioural changes with loss of initiative and irritability, concentration and memory disorders) were recognised to be the consequence of cerebral injury only later. The importance of psychological tests for the differential diagnosis is stressed.

Carbon tetrachloride toxicity potentiated by isopropyl alcohol.
Potentiation of carbon tetrachloride (CCl4) by isopropyl alcohol has previously been shown only in rats. Here 14 cases of toxicity in an isopropyl alcohol packaging plant following exposure to CCl4 are described. Renal failure or hepatitis developed in 4. Expired alveolar gas had high acetone levels and the workers were thus metabolically predisposed to CCl4 injury. Stricter limits for CCl4 exposure (present U.S. TLV: 10ppm) are required when there is concomitant exposure to isopropyl alcohol.

CIS 77-704 Criteria for a recommended standard - Occupational exposure to phenol.
Recommendations are made for the prevention of occupational diseases due to exposure to phenol. The time-weighted average exposure (10h working day) should not exceed 20mg/m3 over a 40h week. The ceiling concentration is fixed at 60mg/m3 for any 15min period. Other recommendations relate to medical supervision, labelling, personal protection, information of employees, work practices, sanitation, monitoring and recordkeeping. The criteria on which the recommendations are based are discussed under the following heads: biological effects of exposure, environmental data, development of the standard, research priorities. Procedures for sampling and analysis in air are detailed and useful additional information is given in appendices.

Effects of catechol on human subjects.
Data from medical examinations of 13 workers exposed simultaneously to catechol and phenol vapours are reported and supplemented by data from animal experiments. Procedures for colorimetric determination of catechol in the air and urine in the presence of phenol are described. Average exposure concentrations of catechol and phenol were 1.8ppb and 55.6ppb respectively. The chief complaints were related to the upper respiratory tract, confirmed by clinical examination. No evidence suggested metabolic inhibition between phenol and catechol.

Exposure to butyl alcohol - Uptake and distribution in man.
12 subjects were exposed to 300 or 600mg/m3 of n-butyl alcohol in inspired air during rest and exercise (4 periods, 30min each) on a bicycle ergometer. The results were puzzling in view of the high blood/air partition coefficient for the alcohol. The arterial blood concentration was low, as was the concentration in the last part of the expired air ("alveolar" concentration). The ratio of alveolar concentration to inspired air concentration was low in relation to the low percentage uptake. The high solubility of the alcohol in water may explain the results. Butyl alcohol was probably partially taken up in the water of the dead space mucous membranes during inspiration. It was then partially released from the membranes. Therefore the concentration of butyl alcohol in the last part of expiration was probably not the same as the concentration in the alveolar air.

Absorption of cumene through the respiratory tract and excretion of dimethylphenylcarbinol in urine.
5 men and 5 women were exposed to cumene vapours of 240, 480 and 720mg/m3 for 2.5-48h, and urinary dimethylphenylcarbinol determined. The average retention of cumene vapours in the respiratory tract was about 50%, depending on the duration of exposure. Excretion of dimethylphenylcarbinol was directly proportional to the absorbed dose of cumene. From these results a test was developed permitting calculation of the absorbed cumene dose over 8h with a precision of about ±13.5%.

Exposure to anesthetic gases and ethanol during work in operating rooms.
Measurement of halothane and ethanol in operating theatres yielded levels of up to 34ppm (exposure of anaesthetic nurses to halothane) and 46.6ppm (ethanol, surgical nurses), with time-weighted averages of up to 12.5 and 15.3ppm respectively. In controlled experiments with exposure to halothane or ethanol about 60% of the substances were retained; ethanol rapidly fell to zero in the end-expired air, while halothane persisted for more than 1h. Effective ventilation of operating theatres calls for local exhaust close to the leakage source in addition to general ventilation. Various aspects of ventilation are discussed.

Use of chlorophenols as fungicides in sawmills.
Occupational hygiene studies at the trimming, grading and packaging positions of 2 sawmills, with results of chromatographic analysis of 3 commercial chlorophenol formulations and of wood dust. Chemistry and toxicology of chlorophenols. The most frequent impurities of the commercial chlorophenols, which are applied by dipping or spraying, were chlorinated phenoxyphenols, diphenyl ethers, dibenzofurans and dibenzodioxins. Analysis of wood dust showed the impurities to be enriched in relation to the chlorophenols themselves, probably because of their low volatility and high stability. Contaminant concentrations were much higher at the plant employing spraying as method of application; the dipping method is therefore preferable, provided that the highly contaminated sludge from the dipping tank is adequately disposed of.

Exposition för butanol - Upptag och distribution hos människa [in Swedish]
12 subjects were exposed for 2h to 200 or 600mg/m3 butanol in inspired air during rest and exercise on a bicycle ergometer. The butanol concentrations in arterial blood and in the last ("alveolar") part of expired air were low. The ratio of the "alveolar" concentration to inspired concentration was low in relation to the low percentage uptake. The solubility of butanol in water may explain the results; the alcohol was probably dissolved in the water of the mucuous membranes in the dead-space during inspiration. It was then partly released from the membranes and the concentration in the last part of the expiration was not the same as the concentration in the actual alveolar air.

Gases formed from furan binding agents.
Furfuryl alcohol and formaldehyde concentrations in the air of coremaking areas of 10 iron and steel foundries were measured. The mean concentration of furfuryl alcohol and formaldehyde was 4.3cm3/m3 and 2.7cm3/m3 respectively. Furfuryl alcohol exceeded its threshold limit value (TLV) of 5cm3/m3 in 22% of the determinations; and formaldehyde (TLV = 2cm3/m3) in 38%. In addition phenol concentration was determined in one foundry; and phosphoric acid concentration in two foundries. The concentrations of phenol and phosphoric acid were far lower than their TLVs.

Metabolism studies in N,N-dimethylformamide - III. Studies about the influence of ethanol in persons and laboratory animals.
Some industrial physicians have pointed out that in workers exposed to N,N-dimethylformamide (DMF) the intake of ethanol can produce symptoms similar to those caused by Antabuse (disulfiram). Because no information is available concerning the levels of DMF and ethanol involved, inhalation studies were carried out in animals and man with known concentrations. In general, a reciprocal inhibition of the metabolism of DMF and ethanol was found. After exposure and previous administration of ethanol in man no increase in the blood DMF level was found. The blood N-methylformamide concentration was however comparatively lower. The mechanism underlying the inhibition of DMF metabolism is discussed together with findings of other authors.

Simultaneous determination of trichloroacetic acid and trichloroethanol by gas chromatography.
The analytical method described is based on extraction of halogenated hydrocarbons with ether containing the internal standard, and rapid methylation of the trichloroacetic acid with 3-methyl-1-p-tolyltriazene at room temperature. Urochloralic acid (β,β,β,-trichloroethyl-D-glucuronide) is hydrolysed with concentrated sulfuric acid. After dilution with hexane, gas-liquid chromatography analysis is conducted with a highly sensitive electron capture detector permitting determination of concentrations <1mg/l. A statistical study showed good reproducibility for determination of trichloroacetic acid and trichloroethanol concentrations between 0.5 and 6mg/l. The use of 1,3-dibromopropane as internal standard and the rapid and efficient methylation method make this analysis simple, accurate and reproducible.

Mixtures of the vapours of 2,6-dimethylphenol (2,6-xylenol) and of methanol, which are formed during production of polyphenylene oxide, are hazardous to the health of exposed workers. Results are reported of experiments in which white rats were exposed to various doses of 2,6-xylenol and methanol, and subjected to repeated inhalation of their vapours separately and together. A synergistic effect of the 2 compounds was noted on both acute (single) and chronic exposure. The combined concentration of 2,6-xylenol and methanol should thus be less than the sum of their TLVs when both are present in the workplace air.

Experimental methanol toxicity in the primate: Analysis of metabolic acidosis.
Methanol was administered to rats, rhesus monkeys (Macaca mulatta), and pigtail monkeys (Macaca nemestrina). Of these animals, only the pigtail monkey reliably developed a severe metabolic organic acidosis resembling that observed in humans. Blood and urine specimens drawn from methanol-treated pigtail monkeys were analysed for organic acid content by gas chromatography - mass spectroscopy (GC-MS), and specific assays were performed for formate. A preliminary study suggested that, after methanol administation to pigtail monkeys, formate concentrations may be significantly greater in the vitreous humour than in the blood, a finding that may have particular significance in methanol blindness. The anion gap resulting during methanol acidosis was accounted for in full by increased blood concentrations of formate. Systemic formate concentrations remained low in rats and monkeys which failed to become acidotic following methanol administration. Formate appears therefore to play a role comparable to that of formaldehyde in the toxicity of methanol.

Decontamination procedures for skin exposed to phenolic substances.
Spraying or swabbing with a mixture of polyethylene glycol 300/methylated spirits (PEG-300/IMS) (2:1 by volume) was shown to markedly reduce mortality, systemic intoxication and burns from exposure to phenol, cumene hydroperoxide, or phenol/acetone cleavage product. In the case of sulfuric acid and sodium hydroxide, PEG-300/IMS (2:1 by volume) was slightly less effective than water as a decontaminant. The mixture did not cause permanent eye irritation and should not present a hazard when used as a spray.

Inhalation of aerosolized ethylene glycol by man.
After a brief review of the literature and a description of the signs and symptoms observed after experimental ethylene glycol ingestion, the authors present their own experiments in humans, in which 19 male volunteers were exposed to aerosolized ethylene glycol in mean daily concentrations of 3-67mg/m3 almost continually for 4 weeks. Blood and urine examinations gave no evidence of the absorption of important quantities of ethylene glycol. There were no serious signs of toxicity but some complaints of irritation of the upper respiratory tract. Irritation became common with an ethylene glycol concentration of 140mg/m3, and more than 200mg/m3 was intolerable. It was concluded that an individual with normal sensory apparatus could not absorb a harmful quantity of ethylene glycol through the respiratory tract. Detailed results of laboratory and psychometric tests are given in tables.

Histopathological liver changes after chronic experimental phenol poisoning
Histologični promeni v černija drob pri eksperimentalno hronično otravjane s fenol [in Bulgarian]
Results of research in 35 rabbits given 0.18g/kg phenol daily for 7-35 days by the intravenous route. The authors noted severe dystrophic changes (non-fatty parenchymal and vacuolar dystrophy) of the hepatic parenchyma, necrobiotic lesions of the hepatocytes, a considerable decline (to complete disappearance) in glycogen and a very great fall in cytoplasmic ribonucleic acid. In animals in which administration was stopped after 35 days they noted a reversal of the dystrophic processes and the return of glycogen and RNA levels in the liver cells to normal values.

Morphological changes in subacute allyl alcohol poisoning and at high environmental temperature
Morphologische Veränderungen bei der subakuten Einwirkung von Allylalkohol und erhöhter Umgebungstemperatur [in German]
Histochemical techniques in a series of experiments in rats showed increased liver toxicity due to allyl alcohol under high environmental temperature (35°C) conditions. These results confirm the hypothesis that elevated environmental temperatures may enhance the toxicity of certain chemical substances.

Measurement of chloral hydrate, trichloroethanol, trichloroacetic acid and monochloroacetic acid in the serum and the urine by gas chromatography.
A gas-chromatographic method for the determination of trichloroethylene metabolites in serum and urine is described. Elution patterns, calibration curves and recovery rates are given. The analytical sensitivity of gas chromatography with an electron-capture detector for trichloro-compounds was found to be superior to that of colorimetric methods. Urinary trichloroacetic and monochloroacetic acid can be determined simultaneously. Methanolic hydrogen chloride was used for methyl esterification, since diazomethane may be carcinogenic.

Influence of dichloromethane on the disappearance rate of ethanol in the blood of rats.
After theoretical considerations on dichloromethane metabolism, results of experiments with rats, exposed to 4,200ppm dichloromethane after intraperitoneal administration of ethanol, are reported and discussed. It is concluded that an influence of dichloromethane on the metabolism of ethanol is unlikely, and that rats exposed to dichloromethane show higher blood ethanol concentrations compared to controls. Therefore, an elevation of blood ethanol level cannot be excluded in workers exposed to dichloromethane vapour. It is emphasised that a possible influence of ethanol on dichloromethane in the organism cannot be judged from the results.
