Exposure to toluene and urinary hippuric acid excretion in a group of heliorotogravure printing workers.
The influence of a number of factors possibly affecting the relation between urinary hippuric acid excretion and the exposure level to toluene was studied in rotogravure printers. After 4h and 8h from the onset of exposure, the hippuric acid excretion rates (mg/min) were in better agreement with the average toluene air concentrations than either the urinary metabolite concentrations (mg/l) alone or corrected for urine density. Apart from differences in exposure level, a substantial proportion of the interindividual variability in hippuric acid excretion could be explained by differences in work load (and consequently in lung clearance for toluene) during exposure. Skin absorption of toluene is probably another factor influencing metabolite excretion. In agreement with previous findings, the hippuric acid excretion rate apparently does not depend on the time of urine sampling during exposure, provided that at least 4h have elapsed from the onset.

Itching erythema among post office workers caused by a photocopying machine with wet toner.
Reports of irritation of the eyes and skin from several Danish post offices all led to suspicion of the photocopying machines used, especially when exposed to direct sunlight and ventilation was not sufficient. The composition of the toner was not known, and it was not possible to ascribe the symptoms to specific chemicals.

Circadian rhythms and behaviour of permanent nightworkers.
Study of rest/activity rhythms of 13 rotary printers on permanent nightshift (average experience 15.5 years). They reported during 1 week the hours of their sleep onset and of their meals, and their subjective appreciation of tiredness and mood. The average sleep duration (7.84h) can be compared with that of day workers and is fairly longer than the duration of day sleep of shiftworkers when they are on nightshift. This long sleep can be attributed to the early bedtime (around 05.00h) and an adjustment of biological rhythms to the schedule inversion. Other evidence (naps, meal time) supports the hypothesis of a physiological adjustment. The fragility of this adjustment is underlined.

Working conditions and accidents in the metalworking and printing industries
Arbetsförhĺllanden och olycksfall i metallprodukt- och grafisk industri [en sueco]
Report of a study undertaken to develop an accident theory for determining a theoretical basis for preventive measures. The study, which was designed especially to determine the interferences occurring in the information exchange between the worker and his environment, was carried out in 7 metalworking plants and 10 printing shops. All reported accidents and workplace situations were analysed over a 6-month period. During this time 130 accidents occurred in the metalworking plants and 54 in the printing shops. From all of these plants every sixth job was selected for job analysis. The development of new methods for evaluating the information exchange at the workplace requires further study of the working environment.

2-Hydroxyethyl - methacrylate and di- and tetraethylene glycol dimethacrylate - Contact sensitizers in a photoprepolymer printing plate procedure.
The platemaking process is described. Five workers developed allergic contact dermatitis in spite of previous testing of the photoprepolymer mixture for contact sensitisation by the manufacturer. The cases are contrasted with another department where no dermatological problems occurred, and differences in working conditions and methods are pointed out. Preventive measures (working methods limiting exposure) are proposed. A list of 25 acrylic compounds that have caused sensitisation reactions is given, with references.

Needed: A closer look at arts and crafts.
This article reviews the occupational health (OH) problems of arts and craft workers in the USA, a growing body of workers totalling some 780,000 painters and sculptors, photolithography workers, art teachers, silk screen painters, commercial artists, stained glass window creators, etc. These are usually home workers, unorganised and uninformed about health precautions, and work very long hours (46% for more than 40h a week), often exposing themselves and their dependants to chemicals. Local exhaust ventilation is expensive for individual artists. An Art Hazards Information Center has been set up in the USA. Aspects covered include: benzene aplastic anaemia hazard in photolithography; toxic art materials used in silkscreening; lead, zinc chloride flux and silver nitrate hazards for stained glass window artists; woodworking hazards; suggested guidelines; information on personal protective equipment; insufficient warning on labels; role of OSHA Office of Toxic Substances; need for legislation requiring labelling describing specific health effects, toxicity rating, precautions and first aid instructions (materials at present sold without warning labels include asbestos, lead, uranium oxide, benzidine-type dyes, cadmium compounds and materials containing silica).

Occupational exposure to printing ink aerosols - An environmental hygiene study
Esposizione professionale ad aerosoli di inchiostri da stampa - Indagine igienico ambientale [en italiano]
Aerosols of ink with a mineral oil content are produced during the operation of rotary printing presses. This study covers the rotary print section of a large Italian newspaper. The oils were separated qualitatively and quantitatively from the other ink components. The mean quantity of oil in the atmosphere was 4mg/m3, below the U.S. TLV. Granulometric analysis by phase contrast microscopy showed the respirable fraction to comprise about 5% of the airborne particles.

Photographers' working environment and occupational diseases
A propos des postes de travail et de la pathologie professionnelle des photographes [en francés]
MD thesis. An introduction consisting of historical background material and a chapter containing technical data on black-and-white and colour photography are followed by a study of workposts and working conditions in small photographic laboratories and in larger, more sophisticated mechanised laboratories. The author considers sources of contamination (before film processing and when using chemicals and other materials) and studies the occupational diseases to which photographic workers are exposed (mainly dermatoses - 10 case studies are given -, poisoning due to the vast number of photographic processing chemicals used (listed in an appendix with their synonyms, chemical formulae, trade names, etc.), damage to the eyes and respiratory tract, postural disorders, physical injuries due to accidents, electric shock, etc.). Other aspects considered include: occupational hygiene, medical prevention, personal protective equipment, statutory compensation covering occupational accidents and diseases, and cases where there is no provision in French law for entitlement to compensation.

Characterization of potential indoor sources of ozone.
Domestic electrostatic air cleaners, 2 photocopy machines, 2 electric typewriters and a portable electrostatic air cleaner were tested for potential ozone generation. Ozone emission from photocopying machines was 48-158µg per copy, giving rise to atmospheric ozone concentrations of up to 396µg/m3 (0.202ppm) in poorly ventilated premises. Days when outside concentrations are greater than 98µg/m3 (0.05ppm) are of particular concern. Maintenance of machines reduced ozone production to below detectable levels.

A report on electromagnetic radiation surveys of video display terminals.
This survey of a newspaper printing plant was undertaken to evaluate the hazards of the different types and models of CRT display terminals. Low energy X-rays, gamma, ultraviolet, visible, infrared, radiofrequency and microwave radiation are produced. The instruments used for the measurements, including luminance, and the terminals are described. A literature review and findings of a previous survey are given to complete the information on the subject. All results agree that the radiation levels produced do not appear capable of presenting an ocular radiation hazard. Cataract and eyestrain causes are in doubt.

Exposure and uptake of toluene in man in a photogravure printing industry - Personal air sampling, direct reading physical instruments and biological sampling
Exposition för toluen och upptag i kroppen vid arbete i ett djuptryckeri - Personburen provtagning, direktvisande instrument och biologisk provtagning [en sueco]
There was no appreciable difference between exposure determined by personal air sampling or stationary direct-reading instruments. Toluene uptake could be estimated by alveolar air sampling during and after exposure, but there was no correlation with the concentration in inspired air. There was a correlation between concentrations in alveolar air and in blood. Uptake was enough to cause a risk of central nervous system disturbances. No change was observed in daily toluene uptake with time in percent of a given amount. Measurements of alveolar air concentrations during, and not after, exposure are recommended.

Allergic contact dermatitis to a photopolymerizable resin used in printing.
The Letterflex process, a new development in newspaper printing, is described. Analysis of the resin yielded 2% additives (benzophenone and di-tert-butyl-p-cresol) and the main constituents (1) a polyene derived from tolylene diisocyanate and an alkyl either derivative of a polyol, and (2) a polythiol ester composed of pentaerythritol and mercaptopropionic acid. 12 of the 15 workers handling the resin had skin lesions. Patch tests and biopsies showed the polythiol to act as a skin sensitiser, confirmed by animal experiments.

Biochemical and psychological studies in persons with long-term exposure to trichloroethylene with reference to exposure-free intervals
Biochemische Untersuchungen und psychologische Studien an chronisch Trichloräthylen-belasteten Personen unter Berücksichtigung expositionsfreier Intervalle [en alemán]
Examination of 8 persons who were occupationally exposed to about 50ppm (260mg/m3) trichloroethylene (the TLV in the Fed.Rep. of Germany) in a printing shop is reported. The purpose of the psychological examinations was to clarify mental function changes correspnding to a "psycho-organic syndrome". In spite of proved incorporation of solvent, no signs of CNS changes were found. Biochemical analysis showed large interindividual variations of trichloroethylene, trichloroethanol and trichloroacetic acid levels in blood and urine and a fall in concentrations after exposure-free intervals. The level of 250mg trichloroethanol and trichloroacetic acid per gram of creatinine, under discussion as an acceptable biological TLV in occupational medicine, was exceeded in all cases. It is proposed to increase it to 300-350mg total metabolites per gram of creatinine. The results are compared with other reports.

Sensitisation eczema due to allergic effect of a resin used in the printing trade
Eczémas de sensibilisation ŕ une résine utilisée en imprimerie. [en francés]
On the rotary presses used for printing major daily newspapers, the metal plates are more and more frequently replaced by flexible stereos of photopolymerisable resins. Cases of eczema have been observed with a process of this type (Letterflex process). A field investigation completed by clinical examinations incriminated one of the resin components, pentaerythritol tetrakis (3-mercaptopropionate). Experiments made with guinea-pigs confirmed the highly allergenic character of this product. Preventive measures: automation of plate preparation process and handling of the resin; installation of efficient local exhaust ventilation; personal hygiene; use of frequently disposable gloves.

Resins used in printing: intolerance phenomena and prevention
Les résines d'imprimerie: phénomčnes d'intolérance et prévention. [en francés]
MD thesis. The use of light-sensitive plastic resin plates on rotary presses has given rise to interolerance to plastics among operators. A general section on the main printing techniques, eczema and irritative dermatitis, and plastic resins, is followed by a report on an occupational health survey at a large newspaper printers employing the letterflex process: machines and mode of operation, nature of the resin and allergological study. A polythiol in the resin was found to be responsible for the allergy. 17 cases of skin and respiratory intolerance are presented, and similar phenomena were sought in other printing shops and using other procedures (Nyloprint, acrylics, polyurethanes). The symptoms were controlled by prevention measures: push-pull ventilation, maintenance of constant temperature and humidity in the workshop, use of protective gloves and barrier creams, showers after work.

Some photocopying techniques - Products used - Toxicology - Protection measures
A propos de certains procédés de reprographie - Produits utilisés - Toxicologie - Prévention. [en francés]
MD thesis dealing with the hazards associated with thermography, diazo copying and electrostatic copying. After a technical introduction, 3 cases of occupational disease are reported with a review of the few cases found in the literature (allergic skin conditions due especially to diethylaminobenzenediazonium chloride, and respiratory disturbances mainly due to ammonia). The small number of such cases contrasts with the large number of toxic products employed, and a long chapter is devoted to this. The techniques studied thus do not seem to present a great hazard for users. But whatever technique is used protective measures are necessary. These are based on the choice of premises and personnel, personal protection, and supervision of personnel and the workplace atmosphere. In view of the trend towards specialised photocopying units, acutely and chronically toxic substances should be subject to strict controls. The refusal of manufacturers to divulge the chemical composition of their products presents a serious problem.

Skin disorders due to acrylic resins in the printing industry
Accidents cutanés des résines acryliques dans l'imprimerie. [en francés]
Progress in printing technology has permitted lead to be replaced by photopolymer resins, which allow production of printing plates that can be used either in conventional rotary presses or the offset process. Adoption of the method in the printing shop of a large newspaper caused several cases of skin disorder among printing workers, in the form of bullous dermatitis, which are described, within two weeks. Allergological studies involved visiting the workshops, chemical identification of the resin responsible (tetraethylene glycol diacrylate), and experimental reproduction of the lesions. Use of tetraethylene glycol dimethacrylate obviated these effects, as a study based on 300 allergy tests proved.

Occupational health rules for work with photopolymers in printing works
Skyddsĺtgärder vid arbete med fotopolymeriserande substanser i tryckerier [en sueco]
Brief description of the principle of the photopolymer plastic plate used in printing, followed by comments on the attendant health hazards of exposure to allergens and rinsing agents such as sodium hydroxide (after hardening of the plate). These directives recommend: replacing of harmful substances by more innocuous ones; local exhaust ventilation at exposed workplaces; enclosure of pressurised water spray washing and fan drying installations; protection against ultraviolet radiation during contact-exposure of plate and negative; exclusion of hypersensitive persons from work with allergens; strict bodily hygiene; skin protection, wearing of personal protective clothing and gloves. Cleaning rags should be discarded after use; personnel should be warned against skin contact with allergens.

Reticuloendothelial status of workers exposed to toluene
Sostojanie sistema krovi u rabočih, imejuščih kontakt s toluolom [en ruso]
Statistical analysis of some 8,000 examinations of peripheral blood samples over a period of 5 years in 396 workers exposed to toluene contained in photogravure inks. The toluene vapour concentrations were 10-30 times the Soviet TLV (50mg/m3). The effect of toluene on the blood is very different from that of benzene. Sternal puncture in 20 cases revealed evidence of erythropoietic and thrombopoietic disturbances. The haematological changes seen in the early years of exposure did not worsen subsequently.

Hazards of wallpaper manufacture
Les risques dans la fabrication du papier peint. [en francés]
Communication submitted to the Regional Joint Technical Committee for the Chemical Industry (Lille, France). Analysis of hazards and their prevention at each manufacturing stage according to the procedure employed (traditional, photogravure or flexographic printing): storage of paper; preparation of inks (falling into the mixer; dragging of the upper limbs by the mixer rotor or the pigment grinder); placing the paper on the reel; printing (crushing by the rolls and gear train; cutting by the doctor blade); web slitting (cutting hazard); drying (falls from heights with closed dryer, and heat exposure with open dryer); reeling, packing and storage; miscellaneous operations (embossing, waste recovery). Sections are devoted to the poisoning hazards from solvent vapours in photogravure or flexographic printing and protection against fire and explosion hazards. The author stresses the seriousness of accidents caused by roll machines and the necessity of training and informing personnel.

Chronic occupational exposure to solvents - III. A gas chromatographic method for the determination of hippuric acid in serum
Chronische Lösungsmittelbelastung am Arbeitsplatz - III. Eine gaschromatographische Methode zur Bestimmung von Hippursäure im Serum [en alemán]
The principle of the method is that serum hippuric acid together with the internal standard of 3,4-dimethoxyphenylacetic acid are converted into the corresponding methyl esters with diazomethane and determined as such by gas chromatography. The detection limit of about 0.6mg hippuric acid in 1l serum permits determination in the serum of toluene-exposed workers as well as that of normal persons. The applicability of the method is demonstrated in 8 unexposed persons and in 98 toluene exposed workers from a printing shop. (Part I:CIS 2697-1973; Part II:CIS 74-0146).

Lung changes due to rare earth
Lungenveränderungen durch "Seltene Erden" [en alemán]
Description of 3 cases of reproduction photographers with over 30 years of exposure to arc lamp fumes: pathology, clinical data and laboratory test findings, respiratory function, radiological picture, anthropospectrometry. Chest radiographs showed milliary or linear opacities in the median fields. Case history, anthropospectrometry and, in one case, biopsy, confirmed the diagnosis of pneumoconiosis due to rare earths and thorium. The observations made show that this type of pneumoconiosis shows no definite disease progression and no serious functional deterioration.

Study of abnormal laboratory findings in workers exposed to diazo developer chemicals.
Report on studies in 9 men at an Armed Forces Station in whom signs of liver disease (elevated serum bilirubin and relative eosinophilia, dark urine) were found on medical examination. The only common factor appeared to be work near a copying machine which used a diazo developing process involving phenolic compounds (hydroquinone and resorcinol had been reported to cause liver abnormalities) and several other substances. Study was extended to 4 further centres: the strongest association observed was between mixing the diazo developer powder and relative eosinophilia. The relationship appears to be confined to laboratory results as distinct from clinical illness, but its nature is unclear.
