Hand dermatitis in the pottery industry
Irritant hand dermatitis has long been recognised in the pottery industry. Among workers handling glaze, sensitisation to chromate was common and allergy to other metals and to biocides also occurred. Allergy to oil additives was found in mould makers. Whilst irritant hand dermatitis does occur, allergy to metals and biocides should be looked for in workers handling glazes, and allergy to oil additives in mould makers.

Study of the solubility of lead compounds used in glazing workshops
Etude de la solubilité des composés du plomb utilisés dans les ateliers d'émaillage [in French]
This document assesses the state of research into the toxicity of industrial products containing lead compounds (lead silicates or "lead frits" as used in ceramic glazes, for example). Present findings are insufficient for any significant conclusions regarding the danger of these products. It is possible, however, to envisage the development of a large-scale toxicological study.

Epidemiological studies on the risk of pulmonary tuberculosis or lung cancer in ceramic workers with pneumoconiosis
Yōgyō jinpaisha no haikekkaku narabi ni haigan ni kansuru ekigakuteki kenkyū [in Japanese]
Retrospective cohort study (1979-1990) on pulmonary tuberculosis and lung cancer in 960 ceramic workers with pneumoconiosis and 337 controls. Those with pneumoconiosis were classified according to categories 1, 2, 3 and 4 of the Japanese X-ray classification of pneumoconiosis. The age-adjusted mortality rate (MR) per 1000 person-years for cat. 4 workers was significantly higher (22.6) than among controls (4.5). Age-adjusted MRs were 2.3 for pneumoconiosis, 3.4 for pulmonary tuberculosis and 5.6 for all cancers in cat. 4 workers, significantly higher than among controls. There were no significant differences for lung cancer. The standardised mortality ratio (SMR), based on Japanese MRs, was estimated for the period 1986-1990. SMRs in cat. 4 workers were 356 for all causes, 294 for all cancers, 909 for lung cancer and 5000 for pulmonary tuberculosis, all significantly higher than among controls. SMRs for these causes in cat. 1, 2 and 3 were not significantly higher. The age-adjusted incidence of pulmonary tuberculosis for those with pneumoconiosis of any category was significantly higher than among controls. The standardised incidence ratios for pulmonary tuberculosis for the period 1979-1990 for all cases of pulmonary tuberculosis and for infectious pulmonary tuberculosis were also significantly higher than among controls for all 4 categories.

Risk of pneumoconiosis in the traditional ceramic industry - Current evidence and results of a cross-sectional cohort study
Le risque pneumoconiotique dans l'industrie céramique traditionnelle: données actuelles et présentation des résultats d'une enquête de cohorte transversale [in French]
The aim of this medical thesis is to analyse the risk of pneumoconiosis and exposure to silica in the ceramics industry, ranked 2nd or 3rd in France according to the number of those with recognised silicosis. The technology and economics of the ceramics industry is described. The risk of pneumoconiosis, its nature, and causal factors in the industry are analysed based on statistical data and current epidemiological evidence. In a descriptive, cross-sectional study of a group of exposed workers in the ceramics industry, possible clinical, radiological and spirometric abnormalities are analysed in terms of total exposure to silica dust. The results obtained are compared with data from the literature and suggest a relatively low risk and an evident trend towards a reduction in the frequency and gravity of silicosis.

Evolution of silicosis in the ceramic and glass industries
Silikoseentwicklung in der Keramik- und Glas-Industrie [in German]
Chest X-rays of 60 workers in the ceramics and glass industries, with dust exposure of up to 35yrs, were evaluated. For each worker, an average of 10 chest X-rays were available. In the majority of cases silicosis had not yet progressed to functional impairment after 32yrs of exposure. In a few cases severe forms of silicosis were observed after much shorter exposure times. Type A opacities were present in 8% of the cases and type B in 2%.

Radioactivity in zirconium oxide powders used in industrial applications
Recent work involving the decommissioning of a former ceramic manufacturing facility licensed by the Nuclear Regulatory Commission for activities involving depleted uranium oxide has discovered the presence of unexpected high levels of natural radioactivity in non-licensed zirconium oxide powders also used in the same utility. A comparison between the levels of source material found in samples of this material and the current regulatory guidance for licensed activities and decommissioning was conducted. It has been determined that the level of radioactivity in the zirconium oxide is high enough to raise health physics concerns in the areas of licensing and regulatory compliance, decontamination criteria, and worker health and safety. An examination of these areas was conducted and implications associated with the findings are presented.

Psychological responses to thermal stress in a glass bangle factory
Behavioural studies were conducted on a random sample of 38 glass bangle workers engaged in various occupations and exposed to high ambient temperature (38.2 ± 3.4°C) and radiant heat (46.2 ± 5.1°C) during their work in the glass bangle industries at Firozabad, India. The control group consisted of 22 subjects of similar age and socio-economic status. Series of tests were used to assess the behavioural changes induced by the existing heat stress. The mean scores of immediate memory were much lower in the exposed population indicating impairment of immediate memory in the study group. Visuo-motor coordination and vigilance were also significantly affected. Visual perception showed a downward trend among the glass bangle workers.

Epidemiologic study of cadmium and lead in the hair of ceramists and dental personnel
The cadmium and lead content of hair in 70 ceramists was studied, with a comparable group of 75 dental personnel used a control cohort. The median levels of both metals in the hair of the ceramists was significantly higher than among the dental personnel. Those ceramists whose studios were ventilated showed significantly lower levels of both metals in their hair. The use of protective masks or respirators was associated with significantly higher levels of cadmium in the hair of ceramists. A review of the literature on the subject is presented and the health significance of the results is discussed.

New trends in the use of metals in jewellery
Owing to the constant increase in the number of cases of nickel sensitisation seen in most allergy departments of dermatology and to the fact that sensitisation to nickel is almost always through contact with jewellery and imitation jewellery, an update was carried out on the metal alloys principally used in the manufacture of such jewellery (earrings, bracelets, necklaces, rings, watch straps, etc.). The conclusions of this review demonstrate that nickel is irreplaceable in the majority of the alloys because of its excellent technical properties and low price and, as a result, the percentage of sensitisations to this allergen will not only maintain their present high level but will probably increase in the future.

Cancer risk among glass factory workers: An excess of lung cancer?
A total of 3749 workers employed for at least three months in two Finnish glass factories (cohorts A and B) were followed up for cancer in 1953-86 through the Finnish Cancer Registry. The risk of cancer was analysed by primary site, type of work, years since first exposure, and age at diagnosis. The only significantly increased risks were those of lung cancer among men. It is postulated that the excess risk of lung cancer, detected in this study, can also be accounted for by lifestyle, and not only by possible occupational exposures, because a similar excess risk of lung cancer has been found previously for all industrial workers in Finland.

Ventilatory dysfunction in glass bangle workers
The pulmonary function status of 73 glass bangle workers suffering from chronic bronchitis having varied exposures to pulmonary toxicants in the work environment was evaluated in 1984. The findings were compared with those observed in 220 asymptomatic glass bangle workers and 88 unexposed controls. There was a higher prevalence (45.2%) of ventilatory dysfunction in the chronic bronchitic cases as compared to 19% in the asymptomatic workers and 2.3% in controls, respectively. The relative risk of airway obstruction was 8.3 and 19.6 times higher in the asymptomatic and chronic bronchitic workers respectively as compared to the control (p < 0.001). Age > 30 was found to be significantly associated with bronchial obstruction in chronic bronchitic cases. The occupational and environmental factors responsible for the high prevalence of chronic bronchitis and associated ventilatory dysfunction in relatively young glass bangle workers are discussed.

Contact sensitization among ceramics workers
139 workers from 3 ceramics factories underwent a dermatological and allergological examination, using standard and occupational patch test series, in order to evaluate the prevalence of dermatitis and contact sensitisation, to identify the most important sensitising substances in the ceramics industry, and to correlate the results with possible risk factors such as atopy. Hand dermatitis had affected 37% of the subjects examined. 27% of the workers were sensitised to 1 or more allergens. Of 52 subjects with dermatitis, 37% had allergic contact dermatitis and 63% irritant contact dermatitis. 18 subjects were found to be sensitised without showing any previous or present clinical symptoms. Atopy tended towards correlation with the overall incidence of dermatitis, though not with the prevalence of sensitisation.

A report on the environmental conditions at seven European ceramic fibre plants
This report presents the results of occupational hygiene surveys in seven European ceramic fibre production plants, along with the rationale and methods used to calculate each worker's cumulative exposure to airborne dust and fibres. Details are given of airborne fibre concentration by occupational group (respirable and inspirable fibre concentrations and mass concentrations) along with fibre size and concentration data. Individual respirable fibre concentrations ranged up to 2.4 fibres/mL in the case of production workers and 3.4 fibres/mL for secondary production workers. Comparisons are made with other studies in similar production plants.

Occupational asthma due to cuttle-fish bone dust
Asma professionale da inalazione di polvere di osso di seppia [in Italian]
This report describes a new case of occupational asthma in a goldsmith. A 25-year-old female suffered attacks of urticaria and asthma at each exposure to the dust of cuttle-fish bone used to polish gold jewellery. A specific occupational bronchial provocation challenge showed a dual asthmatic response with a maximum fall in FEV1 of 26% of the baseline value after 6 hours. A pick-test with crude cuttle-fish bone dust in glycerin 10% also gave a positive response.

Mortality and cancer incidence in workers with silicosis in the ceramics industry
Mortalitet och cancerincidens hos arbetare med silikos inom keramisk industri [in Swedish]
Mortality and the incidence of cancer were investigated in male workers with silicosis from the Swedish ceramics industry. The anticipated numbers of deaths and cancer cases were calculated from national rates standardised for age and calendar year. Mortality from 1951 to 1985 in the 314 studied men was significantly increased because of increased mortality due to silicosis and tuberculosis, but there was no increased mortality due to malignant disease. The total number of cancer cases from 1958 to 1983 in 280 studied men was not increased, but there was an increased incidence of lung cancer, especially when a long time had elapsed after the silicosis diagnosis. Exposure in the Swedish ceramics industry did not include known lung carcinogens except for quartz. The increased risk of lung cancer may have been caused by quartz dust, impairment of lung function or by some fibrosis-related mechanism.

Optical radiation in hand-blown glass factories - Study of protective measures
Rayonnements optiques dans les verreries à main - Etude des moyens de prévention [in French]
Results of the 2nd part of a general survey carried out in 4 hand-blown glass factories, in which 21 workplaces were studied. (For the 1st part, see Note No.1617-126-87 under CIS 87-1057). The aim of the survey was to control the efficiency of the preventive measures used and to make recommendations based on French Standards NF S 77-104 and NF S 77-106. The results show that except for those using 'bleu fondeur' filters, all protective measures were effective. Standards defining welding (NF S 77-104) and infrared (NF S 77-106) filters are not adapted for the measurement of radiation in hand-blown glass factories (in particular, the spectral band widths covered are not broad enough).

The social meanings of time off-work: a case study from a pottery factory
An intensive study of sickness absence in a large pottery factory shows that shop floor workers take time off in cycles, some familiar, some less often noticed. The author and his colleagues combined use of company records on absence and sickness with participant observation, and also interviewed a stratified random sample of employees. It is shown that there are different distributions by day of week for unexcused and excused absences; that there is a complex seasonal distribution, linked to holidays, which differs for men and women; and that the distribution of absences across the working life does not conform to the tendency of people to report a greater degree of incapacity as they age. Qualitative data suggest that men and women of differing age and marital status behave as household and kin relations demand. It is thus unsatisfactory to account for cycles of sickness absence in terms either of individual attitudes to work ('malingering') or of the direct impact of biomedical conditions ('genuine sickness'). What the meanings behind the cycles reveal is that sickness absence is a structured social process.

Respiratory symptoms and pulmonary impairment in male and female subjects with pottery workers' silicosis
Respiratory symptoms, smoking habit, lung function and radiological category of silicosis were assessed in 276 present and former pottery workers who were receiving industrial disablement benefit for silicosis. There were 140 females and 136 males. The proportion with conglomerate disease (massive fibrosis) was similar in both sexes. The FEV1 declined with increasing X-ray category of silicosis irrespective of smoking habit and was most marked in subjects with symptomatic chronic bronchitis. In females who had never smoked the average decline of FEV1 in those with simple silicosis was 18mL year-1 and for those with conglomerate disease 38mL year-1. Symptomatic chronic bronchitis was common and only partly related to smoking, occurring in 69% of 101 non-smoking female silicotic patients. No significant changes were observed in vital capacity, lung volume or transfer factor for carbon monoxide.

Annual change in the development of pneumoconiosis and pulmonary dysfunction
Yōgyō-jinpai no shinten to haikino-shōgai no keinenhenka [in Japanese]
The development of pneumoconiosis and of pulmonary dysfunction accompanying it was studied in 623 workers of the ceramic industry. All of them had been under observation for a period of 4 years or more. Spirometry and flow volume curve measurements were carried out to chart the annual changes in various pulmonary function indicators. It was observed that the decline in %VC/Ht (mainly used as an indicator of constrictive impairment) remained at about the same level throughout all the stages of the development in radiographic findings. On the other hand, the decline in %FEV1.0/Ht or %V50/Ht (chiefly indicative of obstructive dysfunction) was greater in the PR3 and PR4 groups than in other groups, and was shown to increase rapidly with more advanced stages found in radiographic findings. Where the stage of the disease in terms of radiographic findings was within the PR1 - PR3 range, small-airway dysfunction was greater than central airway dysfunction.

Risk of abnormal lead absorption in glass decoration workers
Rischio di abnorme assorbimento di piombo nella decorazione del vetro [in Italian]
Following the observation of abnormal lead absorption (PbB 72µg/100mL) in a young female glass decorator in a routine laboratory test, blood lead levels were measured in glass decorators of an entire area of Northern Italy. Abnormal lead absorption was found in a large number of glass workers, the source of exposure being the high content of inorganic lead in the "low-melting" paints that were used (brush and spray painting). Most of the exposed workers were females of fertile age, for whom even a moderate exposure to inorganic lead may constitute a risk during pregnancy. Attempts to reduce lead exposure levels by means of a health education programme and environmental improvements at the workplace were unsuccessful. In conclusion, a reduction in lead absorption in female glass decoration workers can only be achieved by using "low-melting" paints with a lower lead content.

Contact dermatitis from nickel - An investigation of its sources
Patch tests with the GEIDC standard series of allergens, and with 8 washers made of copper, nickel, nickel-palladium, palladium, brass, bronze, gold and iron, were carried out in 964 consecutive patients who complained of intolerance to metals and in 200 controls who did not. All subjects were also questioned as to personal and family history of atopy, occupational contact and intolerance to gold. The results provide support for the substitution of nickel in imitation jewellery with metals such as palladium or bronze.

Lung cancer among glass fibre production workers: A case-control study
To test the hypothesis that processes producing or using finer (respirable) fibres may be related to a higher risk of lung cancer, a nested case-control study was carried out. Included were 73 cases of lung cancer and 506 matched controls, for whom jobs held and processes worked on were blindly recoded in more detail than for the cohort study. Workers known to have been employed on processes containing respirable fibres had a relative risk of lung cancer of 1.2 (95% confidence interval 0.7-2.0) compared with other workers. There was no evidence of a relationship of lung cancer to fibre diameter, duration of exposure, or time since first exposure. Although the study has not indicated a differential risk of lung cancer among workers exposed to finer diameter glass fibres, the exposure levels were low and the number of cases small.

Effects of informing workers of their health risks from exposure to toxic materials
This study compares the mental health, attitudes, and smoking behaviour of 133 workers who had been informed of health risks from exposure to toxic materials on the job with 137 workers who worked in similar conditions but who had not been told that their health was at risk because of exposure to toxic materials. The informed workers reported more health problems than the controls, but there were no significant differences between the informed and uninformed groups in mental health, attitudes toward health hazards in or outside the workplace, or in smoking rates. Ninety percent of all respondents felt that exposed workers definitely should be told of their health risks. These findings indicate little psychological risk from informing workers about their risks because of exposure to toxic substances and a strong desire on the part of workers to be informed.

Prevention of elbow disorders caused by prolonged leaning. Study of the work station of glass cutters
Prévention des affections du coude provoquées par un appui prolongé. Etude du poste de tailleur de verre [in French]
Elbow disorders among manual cutters, polishers and engravers are recognised occupational diseases in France. This paper studies the factors which cause these disorders to appear and develop and gives the results of on-the-job measurements of vibrations and forces to which elbows are subjected and also of a brief survey of the frequency of these disorders. The analysis of the workplace is accompanied by a description of a simple mechanical device enabling the worker to lean on the forearms rather than on the elbows. The device should put a stop to elbow disorders among glass cutters, and could also be used in other industries with similar working postures.

Characteristics of infrared radiation in the glass industry
Harakteristika na infračervenata radiacia v stăklarskoto proizvodstvo [in Bulgarian]
An assessment of infrared radiation exposure is made for the entire technological process in the glass industry, and data are given on lengths of exposure. Glass-blowers are constantly exposed to infrared radiation of 1.5 to 7cal/cm2/min. Most significant is the exposure to 1.5 cal/cm2/min. This makes infrared radiation a serious risk factor in the glass industry.

Influence of the recrystallisation of ceramic fibres on their effects on men
Der Einfluss der Rekristallisation keramischer Fasern und deren Wirkung auf den Menschen [in German]
The state of the present debate about the biological availability of man-made mineral fibres is described. The behaviour of all these fibres at temperatures up to 800°C and of ceramic fibres up to 2,000°C is shown. The ceramic products heated to more than 1,000°C recrystallise, and only a part of them consists of mineral fibres. These fibres have little mechanical strength, and only a part of the recrystallised material contains cristobalite. The silicogenicity of cristobalite is discussed.

Cause-specific mortality among Rhode Island jewelry workers
Death certificates for Rhode Island (USA) jewellery manufacturing workers from 1968 to 1978 were examined. Elevated ratios among males were observed for nonmalignant kidney diseases, liver cancer, drug dependence and accidental poisoning. Among females, the elevated ratios occurred with stomach cancer, peptic ulcer, skin diseases and drug dependence. Possible reasons for the elevated ratios are discussed.

Optical radiation in hand-blown glass factories. A study of 21 workplaces
Rayonnements optiques dans les verreries à main - Etude de 21 postes de travail [in French]
Survey carried out in 4 glass factories in order to investigate risks to glass workers from the energy emission spectra of the different heat sources used. The methodology is described and the findings are interpreted in terms of the limit values proposed by the American Conference of Governmental Industrial Hygienists. It is demonstrated that near and mid-IR radiation (IRA and IRB) can be dangerous (cataracts, cornea irritations) at pots and tank cells and that actinic UV and near and mid-IR can constitute a threat to the eyes and skin at gas furnaces and fire-finishing burners (kerato-conjunctivitis, photokeratitis, erythemas). These problems can be solved only by using suitable screens.

Cancer mortality of an Italian cohort of workers in man-made glass-fibre production
This study was undertaken in order to examine possible long-term effects, particularly cancer, associated with working in the man-made glass-fibre production industry in Italy (glass wool and continuous filament). All male production workers employed for a minimum of 1yr between 1944 and 1974 were admitted to the study (1,098 subjects), and their mortality was examined in the period 1944-1983 (21,325 person-years). The vital status ascertainment was successful for 98.9% of the cohort members. An increased risk of cancer of the larynx was noted based, however, on only 4 deaths. When contrasted with the values of the local population, the increase proved to be statistically significant after 25yrs since first exposure. The higher than expected larynx cancer mortality was confined to workers hired before the age of 25yrs, exposed for at least 15yrs, who started exposure before 1960 (main production: glass wool), and who belonged to the highest cumulative exposure categories.

Computer-assisted assessment of the external respiratory system in expert evaluation of performance abilities of patients with dust-induced bronchitis
Ispol'zovanie ėlektronno-vyčislitel'nyh mašin dlja ocenki sistemy vnešnego dyhanija pri ėkspertize trudosposobnosti bol'nyh pylevym bronhitom [in Russian]
211 patients with dust-induced bronchitis (workers in the ceramics, refractory products and paper-making industries) were examined. Length of exposure for all was more than 10yrs. In addition to detailed clinical and x-ray examination, all patients were subjected to spirography, pneumotachometry and oxyhaemography. Computer-assisted factor analysis was used to derive 4 internal parameters reflecting external respiration status. Of these parameters, the "ventilatory function" factor (VF) gave the best generalised characterisation of the state of the external respiratory system. VF permits an accurate assessment (screening-test) of respiratory system status in workers in dusty occupations.

Mortality study of workers in the man-made mineral fiber production industry in the United Kingdom
The workforces of 2 factories in the United Kingdom have been followed up to the end of 1984 as part of the collaborative European study of the health of workers in the man-made mineral fibre industry. In the cohort from an English glass-wool plant there was no suggestion of any excess mortality compared to national or local rates, except for lung cancer among men in comparison to the national level. However, the data indicate that the workers were largely local persons by place of birth, occupation, and death, and they therefore suggest that the national comparison was inappropriate. Lung cancer mortality showed little relationship to length of employment, duration of time since first exposure, occupational classification, or level of exposure. In the cohort from a continuous filament plant in Northern Ireland no excess mortality from cancer was found. There were, however, raised death rates from violent causes and cardiovascular disease, but these rates were not exceptional for the area of the country in which the factory was located. No deaths from mesothelioma were reported in either cohort.

Known confounding factors could not completely account for the excess observed. Among the numerous studies carried out on man-made glass-fibre workers, only 1 incidence study in France supports our findings. No other increased cancer risks have been suggested by the present study.
