Blood lead and blood pressure - An analysis of health examination materials in two companies for lead poisoning
Chichū enryō to chiatsu - Bōni jigyōjo de no en kenshin shiryō kara [en japonés]
Whether blood pressure is higher among those occupationally exposed to low concentrations of lead is a matter of interest in recent epidemiological studies. To explore this issue, 348 male workers in a vinyl chloride-manufacturing company and a newspaper company were examined. Both systolic and diastolic blood pressure appeared to increase with age and obesity. Blood levels decreased as obesity increased. Systolic blood pressure was higher among those with high blood lead levels (7µg/dL or more), when they were both young (less than 43 years old) and less obese (less than 3.5% of the obesity index). Systolic and diastolic blood pressure appeared to be higher among those with high blood lead levels when they were obese, irrespective of age. Partial correlation coefficients were calculated.

New data about occupational risks associated with photocopying
Novi danni za professionalnija risk pri fotokopirane [en búlgaro]
Thirteen operators were examined for occupational dermatoses necessitating reassignment. The concentration of airborne ozone 60min after setting the machines in operation was 0.15-0.17mg/m3. Attemps to detect airborne selenium were unsuccessful. Pruritis, papulovesicular rashes and occupational contact eczema were established 4-6 months after beginning work. Confirmed contact allergens in 6 of the operators were toner type B, drum-cleaning fluid and fuser oil. Epicutaneous tests of mercury, cobalt, chromium, mercaptobenzothiazole, colophany and Peru balsam were positive. Measures for reducing exposure of the operators to the allergens were put in practice.

A register-epidemiology study on cancer among Swedish printing industry workers
The Swedish Cancer Environment Registry, a population-based Cancer Registry, has been supplemented with 1960 census data on occupation and industry. This information system was used to generate hypotheses on occupational high-cancer-risk groups and to discuss some methodological problems connected with register epidemiology. By successive exclusion of parts of the original population of printing industry workers with excess risks of lung and cervical cancer, it was possible to consider similarities and differences between subgroups. The excess risk of cervical cancer disappeared when gainfully employed persons and blue-collar workers were used as controls. After the exclusion procedure there was an excess risk of lung cancer among typographers and lithographers in printing enterprises, especially in some birth-cohorts, due possibly to the working environment.

Outbreak of carbon tetrachloride poisoning in a color printing factory related to the use of isopropyl alcohol and an air conditioning system in Taiwan
Three workers from a colour printing plant were admitted to hospital with acute hepatitis. One of the 3 had superimposed acute renal failure and pulmonary oedema. Results of comprehensive medical examinations of workers from the plant and of an on-the-scene investigation led to the conclusion that the outbreak was in all likelihood due to a combined exposure to carbon tetrachloride and isopropyl alcohol. This outbreak underscores the importance of adopting appropriate industrial hygiene measures in a rapidly industrialising nation.

Contact dermatitis in printing tradesmen
During a 2-year period in Toronto, Canada, 21 printing tradesmen with contact dermatitis were evaluated. 67% had allergic contact dermatitis; 29% due to ultraviolet-cured ink components. Irritant contact dermatitis accounted for 33% of the cases. The prognosis in printing tradesmen with contact deratitis is guarded, except for those with allergic contact dermatitis due to UV-cured components, as the tradesmen who were sensitised to other contactants eventually left the trade. Offset lithography was associated with the problem in 18 of the 21 cases. A brief outline is given of the printing processes in common use.

Pneumoconiosis due to rare earths (Cerium pneumoconiosis)
Pneumokoniose durch "Seltene Erden" (Cer-Pneumokoniose) [en alemán]
Slowly progressive restriction in respiratory function was observed in five reproduction photographers who had been exposed to fumes of carbon arc lamps for more than a decade. In all cases interstitial lung fibrosis had developed and accumulations of fine granular dust particles were found in the tissue. Combined analyses including X-ray diffraction, infrared spectroscopy, plasma analysis, X-ray microanalysis and electron diffraction revealed the presence of rare earth minerals (mainly cerium compounds) in all lungs. The rare earth minerals originating from the core of the burned carbon rods used in the arc lamps represent the etiological factors responsible for the development of so-called "cerium pneumoconiosis".

Ozone and other air pollutants from photocopying machines
The ozone emission from 69 different units was determined by a described standard procedure. The emission rates ranged from 0 to 1350µg/min. The maximum ozone concentration in the breathing zone of 19 workers ranged from 0.001 to 0.15ppm. Technical conditions for the amount of ozone generated are described and the efficiencies of activated carbon filters are evaluated. Concentrations for selenium and cadmium were less than the limit of detection, 0.004 and 0.6µg/m3, respectively. Dust concentrations (toner) in the air exhausted from photocopiers ranged from 0.05 to 0.5mg/m3. Vapours from the resins in the toner were detected but the health hazards from these vapours and the possible products from reaction with ozone are unknown and require further research.

Monitoring of lead poisoning in battery manufacturing workers and in printers
Akü ve matbaa işçilerinde kurşun zehirlenmesi taranmasi [en turco]
This survey (with an inserted English-language summary) of 744 battery workers and 604 printers demonstrated high (>49.9µg/dL) blood levels in 25.2% of the battery workers and 4.1% of the printers, while it showed "acceptable" (30-49.9µg/dL) blood lead levels in 16.1% of the battery workers and 6.9% of the printers. Protoporphyrin IX analysis showed a higher percentage of affected workers: 69.8% among the battery workers and 13.2% among the printers registered high (>79.9µg/dL) protoporphyrin IX levels. In general, blood lead level determination proved to be more sensitive a test of lead exposure than protoporphyrin IX analysis.

Whole-body vibration in work in a standing position
Helkroppsvibrationer vid arbete i stĺende ställning [en sueco]
About 100 places of work, including ships, aircraft, trains and printing houses were investigated as regards human exposure to whole-body vibration while standing. Vibration at frequencies of 0.2-100Hz was measured in 3 perpendicular directions under normal operating conditions. Third-octave bands and broad-banded frequency weighted acceleration levels were determined. Low vibration levels, in most cases below 100dBv, were generally found for all environments; in some cases levels were below the perception threshold for vibration. The highest vibration levels were found in the vertical direction but on ice-breakers dominant vibrations in the front-to-back direction could also be demonstrated. No limitations in working-hours should in general be recommended according to the guidelines given in relevant Swedish or ISO standards.

Behavioural evaluation of workers exposed to mixtures of organic solvents
In this cross-sectional study of behavioural performance by printers and spray painters exposed to mixtures of organic solvents, 124 exposed and 116 unexposed workers from 4 plants participated in a battery of behavioural tests, exposure tests and a medical examination. The major solvents concerned were isopropanol and haxane. No significant relationship was found between solvent exposure level and mental impairment as measured in any of the 10 behavioural tests. In comparisons of exposed and non-exposed workers, memory span was significantly shorter in the exposed group, while no significant differences were found in the other tests. No abnormalities of clinical significance were found in any of the workers.

Dermatitis from aziridine hardener in printing ink
13 of 51 workers developed dermatitis of the hands and face after handling a water-based ink containing a polyfunctional aziridine hardening agent made from propylenimine and trimethylolpropane triacrylate. The incidence of dermatitis was highest among the ink mixers who handled the undiluted aziridine, was lower among printers who handled ink containing 2-4% aziridine, and was zero in workers who did not handle ink. The mean latency from 1st contact with the ink to development of the rash was 3.2 months among the ink mixers and 6.2 months among the printers. Improper work practices and inadequate protective clothing contributed to the problem.

Cross sensitivity in colour developers
Four workers in photographic developing laboratories in Singapore developed allergic contact dermatitis in response to the colour developer CD4 (2-amino-5-(N-ethyl-N-(β-hydroxyethyl)amino)toluene sulfonate); they presented with lichen planus-like eruptions and 1 with an eczematous reaction. Patch tests showed that the patients were also sensitive to the chemically related developers CD2 and CD3. 3 of the 4 workers were unable to return to their jobs. Although the 4th took protective measures when returning to work, the dermatitis recurred.

Occupational dermatoses at a film laboratory
A questionnaire survey answered by 103 of the 114 employees of a cinematographic film processing laboratory revealed that 43 of the employees had some exposure to chemicals in their work, and that 21 of them had dermatoses. Clinical examination and patch testing showed that 12 cases were due to contact allergy to one of the chemicals CD-2, CD-3, Metol or PBA-1. Tests with guinea pigs showed the isothiuronium salt PBA-1 to be a potent sensitiser. Two cases of lichenoid reaction to colour developing agents were also seen. Five types of protective glove were tested. CD-2 and Metol penetrated all 5, CD-3 penetrated thin polyvinyl chloride, polyethylene and latex, and PBA-1 penetrated none.

Following a fatal case of aplastic anaemia in a printer, dermal and respiratory exposures to dipropylene glycol monomethyl ether, ethylene glycol monoethyl ether and a range of aliphatic, aromatic and halogenated hydrocarbons used for offset and ultraviolet-cured multicolour printing were evaluated in a search for possible workplace substances with marrow toxicity. Evaluation of 7 co-workers revealed normal peripheral blood pictures, but bone marrow specimens demonstrated clear patterns of injury in 3, and the others had non-specific signs of a marrow effect. These changes could not be explained by known risk factors. Possible bone marrow toxicity resulting from exposure to glycol ethers and ultraviolet curing processes is suggested. Peripheral blood counts were an insensitive tool in the study of haematologic toxins acting at the bone marrow level.

Genotoxic effects of occupational chemical exposure
Työperäisen kemiallisen altistumisen genotoksiset vaikutukset [en finlandés]
A study of groups of workers in the reinforced plastics, rotogravure printing and rubber industries. The reactivity, metabolism and mutagenicity of some potential problem chemicals were studied in the laboratory. Worker exposure to genotoxic agents was then assessed by determining the mutagenicity of urine samples, with bacteria as the indicator organisms. Examination of lymphocytes from the workers showed a marked elevation in chromosomal aberrations in reinforced plastics workers, who are exposed to styrene; rubber workers, who are exposed to several agents, showed frequencies of chromosomal aberration only slightly higher than control values, and printing industry workers, exposed to toluene, showed no increase at all. Smoking was associated with chromosome defects. There was no elevated frequency of spontaneous abortion among women in the rubber industry as a whole, and no teratogenic effect was observed. A subset of the women in the rubber industry was at risk of spontaneous abortion, but no cause was identified.

The effect of lifting tables on workload in the graphics industry
Lavanostimen vaikutus nostotyön ergonomiseen kuormitukseen graafisessa teollisuudessa [en finlandés]
Description of an automatic lifting table used to reduce the workload involved in lifting paper stacks in a printing shop. The table was placed at the loading and unloading ends of a guillotine shear. Average load on the whole body of the workers involved decreased by 35%, load on the back by 40% and on the lower limbs by 90%.

Research into the influence of dark-room work on the visual system
Untersuchungen über den Einfluss von Dunkelraumarbeit auf das visuelle System [en alemán]
Ophthalmologic study of 150 workers in the film-production industry who regularly work in dark-rooms. Results are classified according to subjective complaints and pathological findings, taking into consideration immediate adaptation of the eyes and sensitivity to glare. Half the workers had neurovegetative disorders (not confirmed by pathological observations). Results of nyctometric examinations were all within the normal range. The neurovegetative disorders can be explained by using Hollwich's hypothesis on the composition of the retina and the energetic proportion of the optic tract.

Different sensitising acrylic monomers in Napp printing plate
Three chemically pure fractions were isolated from Napp printing plate and subsequently identified by nuclear magnetic resonance, infrared spectrophotometry and elemental analysis. One of the fractions elicited positive reactions in 3 Napp-allergic printers, and another fraction elicited a positive response in one of them. The 2 allergens were 2-hydroxyethyl methacrylate and N,N'-methylenebisacrylamide. Hydroxyethyl methacrylate was also found in another printing plate, Nyloprint WD.

Stress and coronary risk in shiftworkers
164 newspaper printing workers exposed to noise of approx. 90dBA were studied by questionnaire (Italian translation of a NIOSH method), psychometric tests, individual health file, and clinical and laboratory data analysis. There was a progressive increase in adaptation and selection with the aging of the working population; a breakdown in adaptation was associated with the main behavioural coronary heart disease (CHD) risk factor such as cigarette smoking; there were no correlations between adaptation indices and laboratory CHD risk factors. At the same time, the reliability of the NIOSH questionnaire for the Italian working population was confirmed.

Allergic contact dermatitis due to urethane acrylate in ultraviolet cured inks
7 cases are reported: 6 were allergic and one irritant. A urethane acrylate resin accounted for 5 cases of sensitisation, one of which was also sensitive to pentaerythritol triacrylate and another also to an epoxy acrylate resin. One case was an allergy to trimethylpropane triacrylate. The process is described, in which plastic containers had print applied to their exterior surface by offset printing and were then led past a bank of intense UV lamps to dry the printed surface. In addition to patch tests on the affected workers, studies on the sensitisation and irritancy potentials of the acrylates and of toluene-2,4-diisocyanate are reported.

A collaborative study of 'ink mist' in U.K. newspaper press-rooms
The printing of newspapers by the letterpress process produces a relatively stable aerosol composed of small droplets of printing ink. Gravimetric and optical methods of collecting and quantifying the ink mist are evaluated and are comparable and reproducible. Levels of ink mist in the press rooms are given in terms of typical benzo(a)pyrene (b(a)p) content (as a measure of polycyclic aromatic hydrocarbon content), which ranged from 0.0052 to 0.018µg/m3. Methods for determining b(a)p in ink aerosols by thin-layer chromatography and high-performance liquid chromatography are described.
