Effects of xylene and alcohol on vestibular and visual functions in man.
10 volunteers were exposed to 6 and 11.5µmol/l xylene for 4h, with or without single doses of ethyl alcohol. Both xylene concentrations combined with 0.8g/kg alcohol increased body sway and nystagmus, but there was little effect on visual function. Xylene alone had little effect on the vestibular system, and negligible effect on function. Alcohol significantly increased blood m-xylene levels.

Chlorophenols and dioxins - Hazards for chemical industry workers and users
Chlorophénols et dioxines - Risques pour les travailleurs de l'industrie chimique et pour les utilisateurs. [in French]
This literature survey of chlorinated dibenzo-p-dioxins reviews animal experiments and epidemiologic studies, and considers accidents such as that at Seveso. While 2,3,7,8-tetrachlorodibenzo-p-dioxin is particularly dangerous, all members of this group are toxic and present industrial hygiene, civil defence and environmental protection problems. They may be present as impurities in manufactured compounds (o-chlorophenols, 2,4-D and 2,4,5-T herbicides, hexachlorophene) or occur during chemical processes including reactions in their industrial preparation.

Effects of nonachloropredioxin and other hydroxychlorodiphenyl ethers on biological membranes.
The pesticide pentachlorophenol (PCP) contains hydroxychlorodiphenyl ethers and other compounds as impurities. The effects of hydroxy derivatives of nonachlorodiphenyl ether (NDE), 2-hydroxy-2',4,4'-trichlorodiphenyl ether (HTDE), and PCP, were studied in the human erythrocyte membrane. The hydroxy NDEs are very potent haemolytic agents. The order of activity is: 2-hydroxy-NDE (nonachloropredioxin)>3-hydroxy-NDE>4-hydroxy-NDE>HTDE>technical PCP>pure PCP. Haemolytic potency varied with the degree of chlorination and to some extent with the position of the HO group. The hydroxychlorodiphenyl ethers can directly alter properties of biological membranes.

Simultaneous determination by gas chromatography of phenol, 2-chlorophenol, 2,4- and 2,6-dichlorophenol, 2,4,6-trichlorophenol, and 2,3,5,6-tetrachlorophenol in the urine of industrially exposed workers.
This method requires a minimum of sample treatment and has suitable sensitivity and selectivity for chlorophenols in the urine of workers exposed in the production of phenoxy herbicides and of pentachlorophenol. The phenolic compounds are separated by steam distillation, extracted into isopropyl ether, and analysed by gas chromatography directly, using flame ionization detectors. The detection limits in urine range from 0.1mg/l urine for phenol to 1mg/l for the di- and triphenols. The naturally occurring metabolites cresol and 4-heptanone are also isolated and can be quantified by this method.

The mortality experience of workers exposed to tetrachlorodibenzodioxin in a trichlorophenol process accident.
All 121 workers who developed chloracne from the accident in March 1949 were followed up. Standardised mortality ratio (SMR) was 0.69, with 32 deaths observed and 46.41 expected. For malignant neoplasms and circulatory diseases, SMR was 1.00 and 0.68 respectively. These results are not conclusive, but the absence of excess mortality over 30 years is important. Broader studies are in progress.

Determination of chlorophenol and pentachlorophenol in air by gas chromatography
Oznaczanie chlorofenolu i pięciochlorofenolu w powietrzu metodą chromatografii gazowej [in Polish]
Review of the industrial uses and toxic effects of chlorophenol and pentachlorophenol (PCP), and methods for their determination in air. Description of a method for determination by gas chromatography with a flame-ionisation detector. The lower limit of the method is 0.03µg p-chlorophenol and 0.15µg PCP per sample. The method is based on the absorption of vapours in a Na2CO3 solution, the chromatography column being filled, in the case of p-chlorophenol, with silicon oil DC-550 at 150-180°C and, in the case of PCP, with diethylene glycol polysuccinate at 190°C to which 2% phosphoric acid is added. The method is highly sensitive and selective. The conditions for determination established for p-chlorophenol can be used for determining concentrations of 0- and m-chlorophenol, dichlorophenol, phenol, and cresols occurring in mixtures in ambient air.

Occupational chronic exposure to organic solvents - VI. Formic acid concentration in blood and urine as an indicator of methanol exposure.
Blood, urine and expiratory air were collected in 20 workers exposed in a printing shop to 85, 101 and 134ppm methanol. The increase in formic acid blood levels during the shift was found to be a very useful parameter for biological monitoring of methanol exposure around 100ppm. Determinations of methanol concentrations in the ambient air or in the exhaled air are only crude estimates.

Is the urinary formic acid level an index of human exposure to methanol vapour?
Je hladina kyseliny mravenčķ v moči ukazatelem śrovně expozice člověka parįm metanolu? [in Czech]
Report of experiments in which 4 volunteers were exposed for 8h to methanol vapour in concentrations approximating to, or double, the Czechosovak TLV (100mg/m3). The methanol dose received in these conditions was relatively small. Methanol metabolism was too insignificant for any increase in urinary excretion of formic acid to be determined. Consequently, monitoring of urinary formic acid cannot be used as an index of exposure to methanol vapour.

GLC analysis of alkylphenols, alkylcatechols and phenylphenols in the urine of workers as a measure to prevent occupational leucoderma.
Gas-liquid chromatographic systems are described for quantitative analysis of p-tert-butylphenol, p-tert-amylphenol, p-octylphenol, p- and o-phenylphenol, 3- and 4-methylcatechol, 3-isopropylcatechol, and 4-tert-butylcatechol. The systems were successfully applied for the exposure assessment of workers in the chemical industry producing p-tert-butylphenol, p-octylphenol and/or 4-tert-butylcatechol. Urine concentrations were higher in product packers, who had higher estimated exposure, than in plant operators and engineers. They were reduced by improved hygiene conditions in the workshops. The importance of biological monitoring is discussed in connection with possible skin penetration. A urinary p-tert-butylphenol concentration of 2µg/ml is tentatively proposed as the biological limit to prevent a leucodermogenic effect.

Other recommendations relate to medical supervision, labelling, personal protection, information of personnel, work and sanitation practices, monitoring and record keeping. The criteria on which the recommendations are based are discussed at some length under the following heads: biological effects of exposure; environmental data; work practices and development of the standard. Research needs are defined and procedures for sampling and analysis, and useful additional information are given in appendices.

Changes in urinary excretion of γ-glutamyl transpeptidase, leucine aminopeptidase and alkaline phosphatase on combined exposure to ethylene glycol and high temperature
Promeni v ekskrecijata na gama-glutamiltranspeptidazata, levcinaminopeptidazata i alkalnata fosfataza v urinata pri kombinirano dejstvie na etilenglikol i visoka temperatura [in Bulgarian]
Results of experiments with rats to determine these changes 2, 8, 15, 30 and 90 days after exposure, separately or simultaneously, to ethylene glycol (EG) (1/8 LD50) and 35°C ambient temperature. The effect of ambient heat alone caused an increase in enzyme excretion at the early stage of exposure, whereas exposure to EG alone caused a reduction in γ-glutamyl transpeptidase (GTR) and leucine-aminopeptidase, and an increase in alkaline phosphatase excretion. The temperature factor attenuated the toxic effect of EG on these enzymes towards the end of the observation period. Changes in GTR excretion are the earliest and most sensitive sign of tubular lesions.

A new method for personnel sampling and analyzing of phenol.
Concentrations of 2.5-100mg/m3 phenol in air were measured by a method involving adsorption of phenol on activated carbon, leaching in diethyl ether and quantitative analysis as a trimethylsilyl derivative by gas chromatography. Recovery was 96-102%; sensitivity was 0.5mg/m3. The method was more sensitive and specific than conventional liquid absorption, and can be adapted for breathing zone monitoring of phenol.

Activity of some enzyme indicators in persons occupationally exposed to phenol and acetone
Prosledjavane aktivnostta na njakoi enzimni pokazateli u lica v profesionalen kontakt s fenol i aceton [in Bulgarian]
The activity of the liver-specific enzymes ornithine carbamoyl transferase, guanase and leucine aminopeptidase was studied in the blood serum of these workers. The mean concentrations of phenol and acetone were several times the exposure limit. There was a statistically significant increase in ornithine carbamoyl transferase and guanase activity. The problem of hyperenzymaemia is discussed.

Influence of industrial factors on the course of cerebral atherosclerosis in methanol plant employees
Vlijanie proizvodstvennyh faktorov na razvitie cerebral'nogo ateroskleroza u rabočih metanolovogo zavoda [in Russian]
Results of clinical and neurological observations in 104 chemical industry workers (84 of whom were exposed to carbon monoxide and to methanol) to study the course of cerebral atherosclerosis. Nearly all the exposed subjects suffered from migraine. Neurological symptoms: tremor of the eyelids and fingers, hyperhidrosis, weakening of dermographic response (or, on the contrary, over-reaction), vascular dysfunction. Clinical and biochemical findings: increase in β-lipoprotein and cholesterol levels, increase in coagulation properties of the blood, etc. - all characteristic signs of atherosclerosis.

Occupational vitiligo induced by p-tert-butylphenol, a systemic disease?
Vitiligo was detected in 54 of 198 men exposed to p-tert-butylphenol (PTBP) during its manufacture. Clinical and laboratory findings are reported. There was evidence of a systemic mechanism, severity of the disease being related to intensity of exposure. There was no evidence of autoimmune disease. Liver damage occurred in the affected workers, and could be related to PTBP.

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.
