摘要:

Urine samples from 36 workers exposed to dichlorobenzidine( DCB)-derived pigments and 12 controls were screened for aromatic amines by a nonspecific colorimetric method and then further analyzed by GC/MS specifically for DCB and monoacetyldichlorobenzidine. Of the samples screened for aromatic amines, six (17%) of the exposed population and one (7%) of the control population registered positive (1.0 part per billion [ppb] or greater). One of the positive samples (5.6 ppb) reflected medication, and the remainder (1.1 to 1.8 ppb) were due to high urinary background. The specific analyses were negative (less than 0.2 ppb) for DCB or monoacetyldichlorobenzidine in all samples.

摘要:

Seventeen workers in a laboratory where research with the gypsy moth was being performed were subjected to a questionnaire and to skin tests in an attempt to clarify the extent of allergy-like reactions in these workers. Ten of 17 reported dermatologic and/or pulmonary reactions associated with exposure to the caterpillar. Of the subjects with reactions, seven (70%) had reactions to allergens in the past. When all the workers were skin tested with various extracts, there was a strong relationship between reactions to the skin tests and clinical symptoms. The documentation of this problem helps to explain the outbreak of cutaneous reactions seen in the general population during the massive gypsy moth outbreak in spring 1981 in the Northeast.

摘要:

We investigated mortality among 1,190 Ontario miners who received Workmen's Compensation awards for silicosis from 1940 through 1975. In comparison with the general population of Ontario these men had elevated all-cause mortality rates, with deaths attributed to nonmalignant respiratory diseases and tuberculosis being primarily responsible. The group of miners receiving their compensation awards between 1940 and 1959 has experienced more than twice as many lung cancer deaths as expected while men receiving compensation awards after 1959 have had lung cancer rates similar to the general population. It is concluded that silicosis is not a benign disease and that efforts must be continued to prevent its occurrence.

摘要:

Job content and workplace components can be altered to assure that lifting stresses remain within the acceptable limits defined for the industrial population-at-large. The plan for redesign advocates (1) maintaining the weight handled within the recommended limits; (2) modifying the workplace to enhance postural stability and to avoid handling weights and excessive physical loading; and (3) increasing available job time by reducing frequency of lifts and/or introducing appropriate rest periods. Limits recommended by the National Institute for Occupational Safety and Health on acceptable loads are reviewed.
