摘要:

AbstractTwo studies of coke workers in Britain, comprising 6,767 men, gave similar results. The proportion of lung cancer deaths was about 20% higher than in manual workers generally. The excess occurred primarily among younger men. The ratio of lung cancers to all other cancers was also higher than expected, with limited data showing no evidence of excessive tobacco consumption. Death rates from other causes were generally favorable.Overall the lung cancer death rates in oven workers were similar to those in non‐oven men, but in both studies some indications of a job‐specific excess were noted. These findings are compared with results from earlier studies in the United States and Canada where a much higher excess lung cancer mortality was found in oven men, particularly those with longer exposure times. We discuss possible reasons for the differences, and conclude that the results reported now contribute further evidence that exposure to coal carbonization fumes can cause lung can

摘要:

AbstractThe proportional mortality experience (1952–1978) of 969 deceased white male granite workers was compared with that of United States white males. Industrial hygiene information was combined with work histories to develop an estimate of lifetime granite dust exposure for each individual. Subjects were grouped into four cumulative exposure categories, and exposure‐response relationships were examined. Trends of increasing silicosis and tuberculosis with increasing lifetime exposure were observed. These are consistent with earlier findings. With the exception of excess suicide among granite workers dying before 1970, there was little evidence of association between other causes of death and employment in the granite indus

摘要:

AbstractCurrently available computerized hospital records from four hospitals in Southwest Oregon were utilized for occupational health surveillance by administering brief occupational questionnaires to hospitalized male patients. Patients with occupational exposure to the lumber and wood products industries showed statistically significant increased risks of hospitalization for diseases of the musculoskeletal system and connective tissue. The technique of using routine hospital records for occupational health surveillance has utility as a simple, inexpensive, but systematic tool for monitoring occupational populations.

摘要:

AbstractTwenty subjects wearing protective respirators were studied during submaximal exercise (80% of Vo2max) on a treadmill. The protective devices were fitted with canister filters of low expiratory resistance and different inspiratory resistances: (0.3, 1.8, 2.8, 3.4, 3.9, and 4.6 cm H2O x sec/liter). The effect of inspiratory resistance on physical endurance, various physiological parameters, and subjective sensations was examined. With the increase in inspiratory resistance, a significant decrease in physical performance, decrease in tidal volume, increased ratio of inspiratory to expiratory time, increased peak inspiratory pressure, and increased CO2retention were observed. The difficulty in inspiration correlated significantly to inspiratory resistance and seems to be the main reason for cessation of the effort. No acceptable upper limit for the inspiratory resistance of the canister filters was found. Any decrease in the inspiratory resistance of the mask's filter enhanced endurance and performance.

摘要:

AbstractOccupational exposure to styrene was studied by environmental and biological monitoring in 22 workers employed in a fiberglass reinforced plastic factory. The mean environmental styrene concentration in individual workplaces ranged from 120 to 684 μl/l. Blood styrene, which was tested at the end of the work shift, ranged from 450 to 3700 μg/l. Urinary mandelic and phenylglyoxylic acid, which were determined at the end of the work shift, ranged from 133 to 2100 and from 107 to 685 mg/l, respectively. Environmental styrene exposure was better correlated with styrenemia than with mandelicuria and phenylglyoxylicuria considered either individually or together. The ratio between environmental and blood styrene showed that styrenemia was, on average, 3.3–4.9 times higher than environmental styrene concentrat

摘要:

AbstractThe frequent association between silicosis and tuberculosis has been known for a long time. However, the possible interrelationship between asbestosis and tuberculosis is not entirely clear, and some reports on the subject are contradictory. The incidence of tuberculosis was determined in three groups of people: 1) those with asbestosis, 2) those exposed to asbestos dust but without asbestosis, and 3) healthy people without pneumo‐coniotic exposure. Chest X‐rays of 2,846 workers surveyed in this department between 1976 and 1980 were reviewed. Since only one case of active tuberculosis was detected, residual tuberculosis was the type encountered and this was diagnosed solely on its radiological signs. The incidence of tuberculosis was: 3.87% (N = 257) for group 1; 3.45% (N = 1,215) in group 2; and 3.93% (N = 1,374) for group 3. Statistical analysis confirms the lack of significant differences in the incidence of tuberculosis in the three groups. From these findings, it is concluded that asbestosis is not an influential factor in the appearance and development of tuberculo

摘要:

AbstractThe worker is the major source of information about job hazards. Frequently, workers themselves discover new occupational diseases. Physicians need to regard the worker as a member of the occupational health team.
