Occupational Exposures to Asbestos in Brazil

International Journal of Occupational and Environmental Health, 1997
European and Canadian asbestos companies have long taken advantage of the lack of regulation of the asbestos industry in developing countries. Their activities exploit vulnerable workers whose lack of medical care may result in a silent epidemic of asbestos-related diseases.

Management of occupational exposure to HIV

Seminars in Dermatology, 1995
Many health care workers (HCWs) are potentially at risk for occupationally acquired human immunodeficiency virus (HIV) infection. 1,z Although improved methods of exposure prevention remain the mainstay of further risk reduction efforts, the likelihood that exposures will nevertheless continue to occur has made it necessary for institutions to develop ...

Occupational Exposure in Portugal in 1999

Radiation Protection Dosimetry, 2001
This study reports the occupational radiation doses for external exposure received in 1999 by the radiation workers monitored by the Radiological Protection and Nuclear Safety Department (DPRSN) in Portugal. Occupational exposures arise from conventional industry, research laboratories, the health or medical sector, and mining.

Adjustment of occupational exposure limits for seasonal occupations

American Industrial Hygiene Association Journal, 1980
A previously reported model for predicting adjustments to permissible exposure limits has been extended to include adjustments for seasonal occupations. On the basis of the model, no "credit" (i.e., increase in exposure limits) may be allowed for a short work season unless the biological half-life in hours of the agent of concern is greater than 38 W ...

Occupational Exposures and Gastric Cancer

Epidemiology, 1998
The role of occupational substances as stomach carcinogens has not been well investigated. In 1979, a population-based case-control study was undertaken in Montreal to explore the possible association between hundreds of occupational circumstances and several cancer sites, including the stomach. In total, 250 male patients with pathologically confirmed
