• Description:
  The purpose of this report was to study tremor in a group of workers exposed to alumina dust using quantitative measurement techniques conducted with physically fatiguing test conditions. Tremor was also assessed by a neurologist using a standard examination protocol. The study included 100 current and former workers employed at an aluminum reduction facility which had been operating since 1966. Available facility records and 1988 sampling data were used to document exposure histories for the worker groups. The findings do not confirm that long term low dose exposures to aluminum (7429905) produced either increased signs or objective accelerametric measurements of tremor. The authors note that the present study provides a more complete assessment of tremor, using both observable ratings and quantitative measurements of tremor. In the current study age was correlated with some tremor measurements, but the test for the interaction between age and exposure was not significant for any of the arm/hand or leg tremor measurements. The authors conclude that potroom workers exposed to aluminum in the range of the proposed OSHA permissible exposure limits do not exhibit increased incidences of tremor.
