A case control study of the relations between risk of back pain sickness absence and the nature of tasks carried out by coalminers
A total of 104 workers with back pain and 215 controls were recruited among coalminers and administered questionnaires on tasks which they had performed as well as on back pain. The mean duration of employment in the coal industry was 17 years and the average length of back pain absence was 16.7 days. Positive associations were found between risk of back-related sickness absenteeism and increased occurrences of lifting more than 50kg with a frequency of more than 20 times in a shift, holding weights above the shoulder height more than 50 times in a shift, carrying more than 50kg and twisting the body while pushing more than 50 times in a shift. A negative association was found with time spent driving free steer vehicles underground. Summaries in French, German and Italian.

Respiratory symptoms and lung function among Sardinian coal miners
A cohort of 909 young miners employed in a Sardinian coal mine between 1977 and 1999 was analysed in a cross-sectional and a longitudinal study. Individual exposure to respirable mixed coal dust was assessed and chest X-ray and lung function measurements were performed. The study confirms a significant relationship between exposure to respirable mixed coal dust, an annual decline of functional parameters and the onset of respiratory symptoms. Age and smoking were associated with a decline in lung function. The effect of smoking seems to lead to functional manifestations of obstructive type whereas the effect of dust appears better correlated to a restrictive or mixed type of damage.

Variation in incidences of tuberculosis in subgroups of South African gold miners
A retrospective cohort study of a group of South African gold miners showed that tuberculosis (TB) was more strongly associated with age than expected. There was also a significant association between TB and occupations such as drilling compared with low dust surface and maintenance work. A profile of mineworkers who are at high risk of TB can be defined by age, mining occupation, silicosis status and HIV infection. TB screening programmes should take special cognisance of these high risk groups. Topics: age-linked differences; cohort study; gold mining; immunodeficiency syndrome; occupation disease relation; risk factors; silicosis; South Africa; tuberculosis.

Mortality of Dutch coalminers in relation to pneumoconiosis, chronic obstructive pulmonary disease, and lung function
In a retrospective cohort study of 3,790 Dutch underground coal miners, excess mortalities from coal workers' pneumoconiosis (CWP) and chronic obstructive pulmonary diseases (COPD) were found. Diminished lung function at medical examination resulted in a significantly increased mortality from COPD, whereas normal lung function yielded expected mortalities from COPD. A positive correlation was also observed between diminished lung function and mortality from CWP. The risk of dying of COPD and CWP increased with decreasing body mass index at the time of medical examination. Topics: body weight; chronic bronchitis; coal dust; coal mining; coalworkers pneumoconiosis; cohort study; emphysema; lung diseases; mortality; Netherlands; pulmonary function.

Quantification of historical dust exposures in the diatomaceous earth industry
Quantitative estimates of dust exposure in a diatomaceous earth mining and milling operation have been derived based on air sampling records for the period 1948-1988. Geometric mean concentrations were 0.37mg/m3 during the 1950s and 0.17mg/m3 during later periods. Exposures were estimated using two linear models, one estimating the changes in concentration over time and the other providing job-specific mean exposures during the more recent period. Average estimated respirable dust concentrations for 135 jobs were 3.55mg/m3 (prior to 1949), 1.37mg/m3 (1949-1953), 0.47mg/m3 (1954-1973) and 0.29mg/m3 (1974-1988). Despite the limitations of the available data, the estimation procedures used are expected to provide reasonable quantitative estimates of silica-containing dust exposure for subsequent exposure-response analyses. Topics: diatomaceous earth; silica; dust level; dust measurement; exposure evaluation; exposure records; job-exposure relation; mathematical models; mining and quarrying; respirable dust.

Mesothelioma in Quebec chrysotile miners and millers: Epidemiology and aetiology
In a cohort of some 11,000 men employed in the Quebec chrysotile production industry, 38 cases of mesothelioma were identified - 33 miners and millers and five factory workers. These cases are described in full, exposure-response patterns are analyzed and the role of fibrous tremolite (an amphibole fibre) in the aetiology of mesothelioma is examined. Case-referent analyses showed that the mesothelioma risk was much greater in a localized area of central mines than in peripherally located mines. Lung burden analyses showed that the concentration of tremolite fibres was much higher in this central area, a finding compatible with geological knowledge of the area. Findings support the view that most, if not all, mesotheliomas are caused by amphibole fibres. This in turn points to durability and biopersistence as critical factors in aetiology. Topics: aetiology; amphibole; asbestos mining; asbestos processing industry; asbestos; crocidolite; chrysotile; amosite; tremolite; cohort study; dose-response relationship; epidemiological aspects; geological factors; histopathology; length of exposure; lung deposition; mesothelioma; mineral fibres; pleural mesothelioma; Quebec.

Chrysotile, tremolite and carcinogenicity
An analysis was made of deaths from mesothelioma, and cancers of the lung, larynx, stomach, colon and rectum in a cohort of some 11,000 Quebec chrysotile workers. Risks were estimated for work in the central mine area and in mines located peripherally. Tremolite concentration was some four times higher in the former area than in the latter. There was increased risk of mesothelioma and lung cancer associated with work in the central mine area, but no increased risk for gastric, intestinal or laryngeal cancer. In the peripheral mines, there was little or no evidence of increased risk for any of these cancers. The hypothesis that, because of the difference in distribution of fibrous tremolite, cancer risk in the central area would be greater than in the periphery was thus substantiated. Topics: amphibole; asbestos mining; asbestos; cancer; carcinogenic effects; chrysotile; tremolite; cohort study; gastrointestinal cancer; hazard evaluation; laryngeal cancer; lung cancer; mesothelioma; mineral fibres; pleural mesothelioma; Quebec.

Respiratory health effects of opencast coalmining: A cross sectional study of current workers
A study of current workers at nine opencast coal mines in the United Kingdom showed that the frequency of (mostly mild) chest radiographic abnormalities was associated with working in the dustier, preproduction jobs in the industry. Although some of these mild abnormalities may have been due to non-occupational factors (aging or smoking), the association with exposure indicates a small risk of pneumoconiosis in these men, and the need to monitor and control exposures, particularly in the high risk occupations. Topics: quartz; chest radiography; coal mining; cross-sectional study; mixed dust; opencast work; pneumoconiosis; respirable dust; respiratory diseases.

The 1891-1920 birth cohort of Quebec chrysotile miners and millers: Development from 1904 and mortality to 1992
Mortality experience of a cohort of some 11,000 male Quebec chrysotile miners and millers, reported at intervals since 1971 and now again updated. 9780 men were traced into 1992. Standardized mortality ratios (SMRs) have been reasonably steady since about 1945. At exposures to less than 300 mcpf.y (million particles per cubic foot x years) average SMRs were 1.07 for all causes, and 1.16, 0.93, 1.03 and 1.21 for gastric, other abdominal, laryngeal and lung cancer respectively. Conclusions are that such exposures have therefore been essentially innocuous, although there is a small risk of pneumoconiosis and mesothelioma. Higher exposures have, however, led to excesses, increasing with degree of exposure, of mortality from all causes and from lung cancer and stomach cancer. Topics: asbestos mining; Canada; cancer; chrysotile; cohort study; dose-response relationship; exposure evaluation; gastrointestinal cancer; long-term study; lung cancer; mesothelioma; mortality; pneumoconiosis; Quebec; respirable dust; smoking.

End-stage renal disease among silica-exposed gold miners: A new method for assessing incidence among epidemiologic cohorts
The incidence of end-stage renal disease (ESRD) was studied in a cohort of 2412 white male gold miners who had worked underground for at least one year. Exposure to silica was evaluated. Based on the 11 cohort members identified with ESRD, the risk in the cohort was elevated compared with the U.S. population. The risk was greatest for non-systemic ESRD and increased with years of employment underground. Results provide evidence that silica exposure is associated with increased risk for ESRD.

A cohort study of graphite workers in Sri Lanka
A cohort of workers from a graphite mine in Sri Lanka was studied in 1987, 1990 and 1993. Radiographic lesions were found in 8.5%, 8.9% and 4.1% of the workers in these respective rounds. Clinical examination of the affected workers revealed 18 cases of graphite pneumoconiosis and 7 cases of active pulmonary tuberculosis in the 3 rounds. The decline in the prevalence of these diseases in 1993 was probably the result of dust control measures introduced in 1972. Five workers who had worked in the mine for an average of 22.6 years developed graphite pneumoconiosis during the course of the study.

Lung cancer in relation to exposure to silica dust, silicosis and uranium production in South African gold miners
In a cohort of 2260 South African gold miners, 78 cases of lung cancer were found during the follow-up period from 1970 to 1986. The risk of lung cancer was associated with tobacco smoking, cumulative dust exposure, duration of underground mining and silicosis. No association was found with uranium production. The results cannot be interpreted definitively in terms of causal association. High levels of exposure to silica dust on its own are important in the pathogenesis of lung cancer and silicosis is either coincidental or represents an increased risk. The risk is also increased in miners spending many hours underground, in which case high levels of silica dust exposure may be a surrogate for exposure to radon daughters.

The survival analyses of 2738 patients with simple pneumoconiosis
To explore whether the inhalation of coal mine dust increases the risk of premature death in miners, a survival analysis was conducted in a cohort of 2738 patients with simple pneumoconiosis in the Huai-Bei coal mine in China. During a follow up period (mean 8yrs) 3.2% of patients with simple pneumoconiosis developed progressive massive fibrosis (PMF). The patients with PMF presented higher age specific mortalities than those remaining in a state of simple pneumoconiosis (SMR: 3.42). After adjustment for tuberculosis and duration of work, the relative risk (RR) of premature death due to development of PMF was 2.4. Tuberculosis was found to be a main risk factor which not only facilitated premature death (RR=2.0), but was also a strong facilitator for development of PMF (RR=7.0). Also, a long term of work underground and drilling as a main job were identified as risk factors for development of PMF.

A cross sectional study of the independent effect of occupation on lung function in British coal miners
Forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) were obtained on 1286 miners in Nottinghamshire with no evidence of pneumoconiosis on X-ray film. Lung function data were also obtained from a control sample of 567 Nottinghamshire men. Multiple linear regression was used to estimate the mean independent effect of mining on FEV1 and FVC after adjustment for age, height, and smoking, in all miners and controls. There was a significant mean effect of mining on FEV1 after adjustment for age, height, and smoking of -155mL, but the size of effect was inversely related to age such that in men of 45 and under the estimated mean effect of mining was -251mL. Occupational exposure to coal dust is associated with a small mean deficit in lung function even in the absence of simple pneumoconiosis, and independently from the effects of smoking. The requirement that miners should have evidence of pneumoconiosis to qualify for compensation for impaired lung function is therefore unjustified.

Comparison of measures of exposure to asbestos in former crocidolite workers from Wittenoom Gorge, W. Australia
This work aims to validate the airborne crocidolite exposure measurements by obtaining measurements of the concentrations of uncoated crocidolite fibres and asbestos bodies retained in the lungs of individual workers, and to estimate the half-life of crocidolite fibres in the lungs. Specimens of lung tissue of former workers known to have died were processed using Pooley's method with TEM for counts of fibres of all types and using Smith and Naylor's method with conventional light microscopy for asbestos bodies (AB). Multiple linear regression was utilized to examine the associations between crocidolite concentrations in the lung and duration of employment at Wittenoom, time since last employed at Wittenoom, nature of job, estimated average fibre concentration at the worksite, and estimated cumulative crocidolite exposure (CCE). There was good agreement between counts of crocidolite fibres, asbestos bodies and CCE. The half-life of crocidolite fibres in the lung was estimated at 92 months. The half-life of crocidolite fibres in the lungs of former Wittenoom workers is about 7-8 years.

Risk of silicosis in a Colorado mining community
The exposure-response relationship for silicosis was investigated among 134 men over age 40 who had been identified in a previous community-based random sample study in a mining town. Thirty-two per cent of the 100 dust-exposed subjects had radiologic profusions of small opacities of 1/0 or greater at a mean time since first silica exposure of 36.1 years. Of miners with cumulative silica exposures of 2mg/m3-years or less, 20% had silicosis; of miners accumulating > mg/m m3-years, 63% had silicosis. Logistic regression models demonstrated that time since last silica exposure and either cumulative silica exposure or a combination of average silica exposure and duration of exposure predicted silicosis risk. Exposure-response relations were substantially higher using measured silica exposures than using estimated silica exposures based on measured dust exposures assuming a constant silica proportion of dust, consistent with lower levels of exposure misclassification.
