Title Long-term trends in exposures to nickel aerosols
Bibliographic information May-June 2000, Vol.61, No.3, p.324-333. Illus. 31 ref.
Abstract A evaluation of the long-term changes in exposure levels to nickel aerosols was conducted using data from 10 nickel-producing and nickel-using industries. Significantly negative linear trends were found for exposures in the mining (-7%/yr), smelting (-9%/yr) and refining (-7%/yr) sectors, while exposures in milling showed a positive trend (+4%/yr). Effects of the work environment, process and nature of the job on exposure trends were evaluated. The decline in exposures was greater in workplaces with no ventilation compared with ventilated workplaces, in workers who performed similar rather than diverse tasks, and in North American workplaces compared with workplaces in Europe and Western Australia. These results could be used in the design of prospective sampling protocols and in future retrospective health-effect studies of workers in the nickel industries.
