ACTH and corticoids levels in plasma with contemporaneous EEG changes during noise in man.
Results of research on 5 subjects exposed to continuous noise levels at 82 and 92dB(A) intensity, and to intermittent noise of variable duration at 92dB(A) intensity. Plasma hormonal levels tended to decrease between 8p.m. and 1a.m., whereas exposure to continuous noise of 92dB(A) resulted in an increase in plasma corticoids which persisted after noise exposure had ceased. ACTH levels also containued to rise after exposure to continuous noise of 92dB(A). Electroencephalographic changes were observed occasionally during exposure to continuous noise of 82dB(A) and fairly regularly during exposure to continuous intermittent noise of 92dB(A); these changes mainly involved synchronisation of the alpha rhythm.

Subclinical neuropathy at "safe" levels of lead exposure.
This study was undertaken to investigate the correlation between blood lead levels (PbB) and the presence of functional disturbances. Highly sensitive neurophysiological techniques revealed subclinical neuropathy in 26 workers from a storage battery factory whose PbB during the entire period of lead exposure of 1-17 years had never exceeded 70µg/100ml. Comparison on an international basis of the method of PbB measurement used showed it to be satisfactory. Measurement of the conduction velocity of the slower motor fibres of the ulnar nerve, the most sensitive test, yielded lower values in the exposed group than in controls. A dose-response relationship was found to exist within the group, but the authors stress that individual diagnosis is not possible. Conclusion: an exposure intensity giving rise to PbB levels below 70µg/100ml can cause slight nervous damage and present concepts of safe PbB levels should therefore be reconsidered.

Psychophysiological findings in patients with writer's cramp.
Two 44-year-old male patients with writer's cramp were subjected to psychophysiological examinations. With regard to microvibration in these cases, irregular fast waves (as an index of mental strain) appeared when they were reminded of writing, and disappeared with discontinuance of the association. The following factors were suggested for the aetiology of writer's cramp: (a) a vicious circle of tremor and nervous character of the patient, aggravated by mental strain; (b) dysfunction of muscle tone adjustment provoked by anticipatory phobia towards writing.

Neurological complications of hydrogen sulfide (H2S) poisoning
Complicaciones neurológicas en la intoxicación por el ácido sulfhídrico (SH2) [in Spanish]
Clinical picture of 2 cases of accidental hydrogen sulfide poisoning; one serious, with 2-min respiratory arrest, then coma lasting 3 weeks followed by Lance and Adam's syndrome (myoclonus). The other case was less serious (3-min loss of consciousness followed by peripheral neuropathy which responded to treatment after 3 weeks). Review of 18 published cases of H2S poisoning with neurological complications following on hypoxia of the central nervous system, but not specifically connected with H2S. The treatment administered is described.

Mental health and working conditions
Santé mentale et conditions de travail. [in French]
Studying the origins of psychopathological disorders, the authors surveyed 50 women assembly-line workers engaged in the assembly of household electrical appliances or the manufacture of safety gloves, and 50 women information switchboard operators: description of the principal disorders encountered, analysis of the characteristics of the work. The results obtained (which are consistent with those of other authors) show that there exists a solid and coherent link between behavioural and character disorders and certain employment factors, such as deadlines for mental tasks and the degree of uncertainty as to the prearranged response to be given when a certain situation arises. Differences between individuals as regards the existence and intensity of the mental disorders are important, but in the great majority of women observed there was a profound state of excitability, nervous tension or depression.

Exposure to methylene chloride - Psychological functions
Exposition för metylenklorid - Psykologiska funktioner [in Swedish]
The effects of dichloromethane on psychological functions, such as reaction time, short-term memory and numerical ability, were studied in 14 healthy young men. Each of them was repeatedly tested during exposure to 870, 1,740, 2,600 and 3,470mg/m3 of dichloromethane in inspiratory air and under control conditions. No measurable impairment in reaction time, short-term memory and numerical ability during exposure could be detected. However, the reaction-time test results obtained during exposure to the highest concentration showed that the intraindividual variation was greater than under control conditions.

Psychological study of medium-depth and deep-sea divers
Etude psychologique sur les travailleurs sous-marins ŕ moyennes et grandes profondeurs. [in French]
After a number of introductory considerations on the psychological aspects peculiar to saturation diving, the authors describe 3 experiments in deep-sea diving (between 350 and 570m) with helium-oxygen mixtures, which showed up the influence of the mode of compression on divers' sensorimotor performance. The last part of the article describes psychological tests for early detection, among probationer or learner divers, of major disorders and possible contraindications.

Effects of noise on people.
An overview of the effects of noise on humans as they can be determined from the scientific literature. Only audible noise is considered. The effects of noise are classified as auditory, psychological and sociological, and physiological. While it is demonstrated that noise can adversely affect the quality of human life, possibly increasing man's susceptibility to disease, the only conclusively established effect of noise on health is that of noise-induced hearing loss.

Occupational nervous system pathology in submerged-arc welders
Professional'naja patologija nervnoj sistemy u rabočih, zanjatyh svarkoj pod fljusom [in Russian]
The results are given of medical examinations carried out on 518 welders as well as of the analysis of air sampled at workposts (heavy dust, manganese and fluoride concentrations). 45 of the welders examined (8.2%) showed functional disorders of the nervous system (excitability, changes in tendon and skin reflexes, vegetative disorders in the distal parts of the extremities, etc.). The symptoms observed resemble those of chronic manganese poisoning. In a few cases, radiographs of the long bones disclosed signs of fluorosis.

Soman and sarin: Clinical manifestations and treatment of accidental poisoning by organophosphates.
Description of 4 cases of accidental exposure to the potent cholinesterase inhibitors sarin (isopropylmethylphosphonofluoridate) and soman (pinacolylmethylphosphonofluoridate). An account is given in each case of the initial clinical manifestations, the therapy instituted and the reactions to therapy. It was observed that: (1) there were psychiatric sequelae in the 2 most severe cases; (2) scopolamine, which disrupts mental performance in normal subjects, ameliorated the mental condition in the patient to whom it was administered, indicating that this drug deserves further evaluation under similar circumstances; (3) the soman-inhibited circulating cholinesterases in one case were refractory to reactivation by pralidoxime chloride, confirming that the effectiveness of the oxime varies with the inhibitor.

Exposure to white spirit - Psychological functions
Exposition för lacknafta - Psykologiska funktioner [in Swedish]
The effects of white spirit on psychological functions, such as perceptual speed, reaction time, short-term memory, numerical ability and manual dexterity, were studied in 22 healthy young men. 14 of them were repeatedly tested during exposure to 625, 1,250, 1,875 and 2,500 mg/m3 of white spirit in inspiratory air and under control conditions. 8 subjects were tested during exposure to 4,000 mg/m3 and under control conditions. Samples of alveolar air were taken at 5 min intervals during the tests. The results indicate that the possibility of impaired performance exists if exposure exceeds 2,500 mg/m3.

Neurosis and railway employment - Results of an analysis of 319 cases of neurosis
Nevrosi e lavoro ferroviario - Risultanze di un'analisi su 319 casi di nevrosi [in Italian]
In-depth survey of 319 cases of neurosis among the administrative and traffic department employees and manual workers of the Italian railways, supplementing a former article of a more general nature. The authors describe the clinical aspects and give the results of psychotechnical tests and of their research into the occupational and non-occupational origins of the neuroses observed. The data collected enable a programme for the prevention of these disorders to be drawn up. To achieve success such a programme should be concerned not only with technical occupational factors, but also with extraneous factors such as family or character problems, etc. which may contribute to the onset of neurosis.

Psychosomatic and psychological state of the injured person
Estado psicosomático y psicológico del accidentado [in Spanish]
Results of a psychological survey conducted by means of the Pinillos personality questionnaire and personal interviews with 2,127 workers who had electrical accidents in the electrotechnical industry, divided into 2 groups according to the cause of the accident sustained: exposure to an electric arc or current passing through the body. Several of the cases studied are described. The survey disclosed that electrical accidents have the peculiar effect of leading to personality and behavioural changes independent of the severity of the accident and unrelated to its sequelae.

The "HVS" effect in electric-power substations
Efecto "PAT" en subestaciones eléctricas [in Spanish]
Describes a syndrome, which the author calls the "HVS effect" (high-voltage substation), which affects persons working at substations where very high-voltage current is transformed and which disappears shortly after the end of the exposure. It is characterised by a feeling of tightness and oppression affecting the head, laxity and fatigue in the upper extremities and persistent insomnia; electroencephalograms show signs of cerebral pain.

Pathological EEG changes in workers exposed to halogenated insecticides
Pathologische EEG-Veränderungen bei Arbeiten mit halogenhaltigen Insektiziden [in German]
This article reviews a number of communications on EEG anomalies observed in persons exposed to halogenated insecticides, and analyses the results of examinations carried out by the authors on 73 workers; pathological EEG anomalies were observed in 29.9% of them, and the occupational exposure was comprised between 7 months and 19 years. Hypotheses are made concerning the biological phenomena occurring in the human brain as a result of exposure to halogenated insecticides. The EEG reverted to normal only several months after cessation of exposure.

Study of the time lag of tendon reflexes among computer keyboard operators
Issledovanie skrytogo vremeni suhožil'nyh refleksov operatorov-vyčislitelej klavišnyh ėlektronno-vyčislitel'nyh mašin [in Russian]
The authors examined, before and after the work shift, the palmar and knee reflexes of 10 young computer keyboard operators. They observed a lengthening of the time lag of these reflexes, due to nervous stress and the heavy workload borne by the neuromuscular system. The left hand was much more affected than the right.

Industrial hygiene evaluation of the effect of low atmospheric concentrations of butyl alcohol on the reflexes
Gigieničeskaja ocenka reflektornogo dejstvija na organizm malyh koncentracij butilovogo spirta, postupajuščego v atmosfernyj vozduh [in Russian]
Results of studies with human subjects aimed at elucidating the effect of inhaling weak concentrations of butyl alcohol on certain reflexes. The study of retinal dark adaptation, chronaxie (conditioned reflex reaction time) and the electrical activity of the cerebral cortex demonstrated that liminal and subliminal concentrations of butyl alcohol (2.5 and 0.5mg/m3) alter these reflexes. A concentration of 0.1mg/m3 had no effect. This latter value is proposed as the TLV for a single exposure.

How to prevent harmful psychogenic reactions in everyday work: A great problem for local governments
Hur förebygga skadliga psykogena reaktioner i dagens arbetsliv: en stor kommunal förvaltnings problem [in Swedish]
A number of workposts selected at random in local government agencies in Sweden were visited and their environments analysed. All employees born on the 10th and 20th of each month were requested to fill in a questionnaire. Medical expert opinion on the psychogenic factors originating from the work situation was obtained. Overwork, extremes of skilled and unskilled work, anxiety about changes in the work organisation and difficulties in co-operation with supervisors and other employees proved to be the most frequent causes for psychogenic reactions. Individual factors should also be taken into consideration. A good health care organisation at the workplace is of great importance for the prevention of psychogenic disturbances.

Psychological performances of workers exposed to various solvents.
Comparative study of the results of psychological tests performed on 168 workers exposed to common industrial solvents (trichloroethylene, tetrachloroethylene, toluene, xylene, etc.), 50 unexposed controls and 50 workers with carbon disulfide poisoning. The performance of the group exposed to common solvents was inferior to that of the control group, but superior to that of the group suffering from CS2 poisoning. The parameters which varied most widely between the groups were sensorimotor speed and psychomotor performances. Visual accuracy was as poor in the group exposed to common solvents as in the CS2-poisoned group. The test battery described appears to be useful for detecting disorders in workers exposed to solvents.

A study of occupational stress and health.
This paper, delivered at the 9th Annual Conference of the Ergonomics Society of Australia and New Zealand (Adelaide, 24-25 Aug. 1971), describes medical and environmental studies carried out among telegraphists employed by an Australian communications organisation, to ascertain impact of occupational stress on health, on the basis of absence records over 2-5 years. Detailed ergonomic and occupational hygiene investigations were also made in the work environment. Absenteeism attributed to neurosis was significantly higher among telegraphists than in other sectors. The author examines the interaction of neurosis, attitudes and habits, job satisfaction, emotional instability and indulgence in habits detrimental to health. Much of the informtion is given in tabular form. He proposes various measures to combat effects of occupational stress on health (scientifically based selection for the task; reorganisation of the work to lessen working group size effects and increase job satisfaction; mental health programmes).

An experimental study on physiological functions of the autonomic nervous system of man exposed to acetone vapour.
Physiological data were collected to determine a TLV for acetone using measurements of galvanic skin reflex, finger reflex (using a plethysmograph), heart rate, respiratory rate and cerebral activity (using an occipital EEG). Subjects were exposed to acetone vapour for various periods; their responses to visual and auditory stimuli were monitored by EEG, and the results compared with a control group. It is concluded that the TLV for acetone should be less than 250 ppm.

Methylchloroform exposure - II. Psychophysiological functions.
Reaction time, perceptual speed and manual dexterity were studied in 12 healthy men repeatedly exposed to 250, 350, 450 and 550 ppm of 1,1,1-trichloroethane (TCE) in inspired air; control tests were carried out with pure air. Exhaled air samples were taken at 2-min intervals. There was a linear relationship between the concentrations in alveolar air and arterial blood. Reaction time, perceptual speed and manual dexterity were impaired during exposure to TCE as compared with exposure to pure air. Analysis of the results shows that psychophysiological functions are adversely affected by exposure to a TCE vapour concentration of 350 ppm.

Threshold limit values and their psycho-physiological significance in noise control
Grenz- und Richtwerte in der Lärmbekämpfung und ihr psycho-physiologischer Aussagewert [in German]
Article discussing threshold limit values for noise established by examination of the ear and the neurovegetative system, followed by an account of recent findings of research on the psychosomatic effects of noise. These studies show that above 90 dB(A), effects recorded can no longer be considered as normal reactions to noise stimuli. This leads to the conclusion that health is endangered between 90 and 100 dB. The author proposes the substitution of a "threshold limit area" for "threshold limit value".

Carbon disulphide as a cause of suicide - Epidemiological study of viscose rayon workers.
In a longitudinal epidemiological study of U.S. viscose rayon workers employed during the period 1938-1948 and observed to 1968, a higher rate of suicide was found among 4,899 white males and females aged 25-64 in certain departments and occupations. The results are set out in numerous tables. It is postulated that, in addition to the acute and subacute toxic effects of carbon disulfide, biochemical and pathological changes intiated by carbon disulfide during occupational exposure may persist over a long span of time and that delayed biological effects of abnormal mental and social behaviour may occur in subsequent years in response to further environmental and social stresses. A national study should be carried out to assess the nature and extent of the population at risk, and research to establish the biochemical precursors to mental illness attributable to carbon disulfide should be carried out.

Psychophysiological aspects of noise
Psychofizjologiczne aspekty hałasu [in Polish]
Depending on personal factors, noise may to some degree or other momentarily activate or permanently impair certain psychic phenomena. The physiopathological consequences can always be observed as hearing and other sense-organ lesions (e.g. balance), or nervous or digestive-system lesions. Carbohydrate, lipid and protein metabolism is also affected. The ear is not the only portal of entry for noise; ultrasonic components of intense noise may affect the mucosae of buccal and nasal cavities, the eye and urogenital membranes.

Hearing and personality: A review
The personality of individuals interacts with their auditory system in a variety of ways. Subjects with different personalities may differ in their psychological responses to sounds, in their perception of sounds and in the way in which noise influences their performance of various tasks. Severe deafness appears to influence the personality of patients, and fairly characteristic changes are found in specific auditory disorders. The annoyance caused by a variety of noises is influenced by the person's personality and, in the past, a noise annoyance scale hs been used as a measure of neuroticism.

Psychological aspects and psychotechnical testing of underwater workers
Aspetti psicologici e valutazione psicotecnica dei lavoratori subacquei [in Italian]
Psychological factors in underwater workers are radically different to pleasure-driving motivation and vary in relation to the type of work (caisson work, constant volume suit diving, SCUBA diving). The author considers the effects of pressure on mental faculties, with reference to the literature, the sensory isolation syndrome and the neuropsychic depth syndrome, and the necessary mental qualities (which vary between caisson workers, constant-volume divers and SCUBA divers); he considers psychotechnical testing essential and indicates the form it should take. Safety measures are reviewed (inclusion of psychotechnical testing in periodic medical examinations, electroencephalography, cerebral theography, psychotechnical-examination card to form part of the driver's personal medical record, compulsory training, health education).
