Investigations of the hazards of exposure to cadmium in 2 plants producing and 2 using cadmium
Investigations sur les risques résultant de l'exposition au cadmium dans deux entreprises de production et deux entreprises d'utilisation du cadmium. [in French]
Account of an occupational health survey covering 163 workers exposed to cadmium and approximately the same number of controls employed in 4 different plants. Detailed description of observations and examinations: questionnaire and clinical examination, lung function tests, ECG and chest radiography, laboratory tests. Findings: slight lung and kidney impairment was found in some workers (the pulmonary lesion consisted of a slight obstructive syndrome, occasionally with incipient emphysema); abnormal laboratory findings became worse with length of exposure; the slight kidney damage was found in 70% of the workers with over 20 years' exposure. Conclusion: the total permissible concentration of Cd in air should not exceed 50µg/m3; furthermore, in view of the correlation between urinary Cd and proteinuria, urinary Cd in exposed workers should not exceed 15µg/g creatinine.

The plant physician and the in-plant training of young workers
De bedrijfsarts en de vorming van jeugdige vaklieden in het bedrijf [in Dutch]
Since all physical loads to which young persons are exposed during their apprenticeship have a lasting effect on their condition, their pre-apprenticeship examination by a practitioner to determine their physical capacity for different occupations is of great importance. The physician should familiarise himself with the strains and stresses inherent in the occupations, to be able to assess a young person's aptitude and his ability to tolerate strain and workload. The author reviews the stresses placed on the locomotor and respiratory systems in the metalworking trades, glassware manufacturing and the electronics industry. Commentary on the results of examination of 425 apprentices.

Effect of strontium-calcium-bismuth titanate on the body in experimental conditions
O dejstvii stroncij-kal'cij-vismutnogo titanata na organizm v uslovijah ėksperimenta [in Russian]
Animal research was carried out to determine the health hazard involved in exposure to titanate powders used in large quantities for the manufacture of magnetoelectric and piezoelectric ceramic materials. After intratracheal administration, a gradual accumulation of dust was observed in the pulmonary tissue, together with discrete cytotoxic and fibrotic reactions. Titanate dust is therefore considered to be only slightly toxic.

The work of the Miners' Health Institute during 1973
L'activité de l'Institut d'hygiène des mines au cours de l'année 1973. [in French]
A detailed bilingual report on research carried out by the medical section of the Institute (treatment of bronchitis; epidemiology of bronchitis among coalminers and steel workers; bronchial disease in the cadmium industry; rehabilitation of patients with respiratory insufficiency) is followed by a report of the work of the technical section (dust control; comparative study of new dust sampling apparatus; dust control in mechanical drifting of new mine galleries; influence of mine supports on dust formation at the face; remote coal seam infusion and effect on firedamp emission; solving ventilation problems by electrical analogy; etc.). The report is also published in Annales des mines de Belgique, Liège, Belgium, 1974, No.11.

Illusory safety when working with dimethylformamide
Schijnzekerheden bij het werken met dimethylformamide [in Dutch]
The introduction of a new electrolyte containing dimethylformamide (DMF) in the manufacture of capacitors prompted a series of tests to assess the permeability of gloves formerly used for protection against an electrolyte containing dimethylacetamide. The test results showed that natural rubber and neoprene are very permeable to DMF, while Hypalon and polyethylene gave much better results. The permeability was lowest with Buta-Sol, which is based on butyl rubber.

Epidemiological survey of workers exposed to cadmium
Enquête épidémiologique des travailleurs exposés au cadmium. [in French]
Preliminary results of a survey covering 80 workers occupationally exposed to cadmium dust (electronics factory, manufacture of Ni-Cd storage batteries, industrial production of cadmium). The authors distinguish 3 groups of effects according to the degree and duration of exposure to the dust. They also take into account the effects of the subjects' smoking habits. Conclusion: prolonged exposure to a cadmium dust concentration lower than the TLV may result in a syndrome of mild respiratory obstruction; kidney damage occurs before lung function impairment. The authors therefore recommend that the TLV for total cadmium dust concentration should be lowered from 200 to 50µg/m3.

A longitudinal study of low-back pain as associated with occupational weight lifting factors.
A review of the importance of occupational low-back pain as a source of work disability and of the methods used to prevent it in the past is followed by an analysis of the biomechanics of weight lifting and a description of a new methodology developed by the authors. This methodology was used first in a pilot study involving 38 jobs and 135 persons, and subsequently in a main study involving 103 jobs and 411 persons (men and women) from 5 electronic manufacturing plants. The findings are described and discussed in detail. It clearly appears that the incidence rate of low-back pain is correlated with higher lifting strength requirements as determined by assessing both the position and the magnitude of the load lifted, and that the lifting of weights is potentially dangerous.

Hygienic assessment of ethylene glycol during the manufacture of certain electronic components
Gigieničeskoe značenie ėtilenglikolja v proizvodstve nekotoryh radiodetalej [in Russian]
Determinations carried out in the atmosphere of 2 electronic components manufacturing workshops showed that the mean concentration of ethylene glycol at critical points was 49mg/m3. No cases of occupational ethylene glycol poisoning were found, but the subjective symptoms noted (headaches, general asthenia, fatigue, etc.) and the functional disorders of the nervous system observed in almost half of the exposed workers point to the neurotoxic effect of this substance. A TLV of 5mg/m3 is recommended.

A luminance concept for working interiors.
Paper presented at the Illuminating Engineering Society Conference held on 24-27 July 1972 at Tulsa, USA. A discussion of preferred object luminances in working interiors includes definitions of minimum and optimum object luminances for ordinary and exacting visual tasks, and an illumination scale. A luminance scale for interior lighting based on preferred wall and ceiling luminance and maximum luminaire luminance is presented; the consequences for practical installations are reviewed. A survey of the lighting installations in a radio components factory and an office based on the author's luminance scale concludes the article.

Polymer-fume fever: Elusive diagnosis
Report of a case of polymer-fume fever in an electronic woman worker which had remained undiagnosed for several months. She had suffered more than 40 attacks as a result of contamination of her cigarettes with polytetrafluoroethylene (PTFE) which she was using as a parting compound for spraying moulds. The patient did not smoke at her bench but usually took a cigarette out of the pack before washing her hands. PTFE resins liberate various degradation products at high temperatures, although the pyrolysis products responsible for polymer-fume fever are not known.
