Description:In response to a request from three employees at the Intalco Aluminum Corporation (SIC-3334), Ferndale, Washington, an investigation was begun into the prevalence of neurological disorders in pot room workers. A progressive neurological disease characterized by tremor, balance problems, bone and joint aches and memory loss had been reported among aluminum potroom workers. Data collection included a questionnaire, neurologic exam, tremor testing using a handheld device (arm/hand) and a Kondraske frame (leg), and tests of postural stability, reaction time, and vocabulary. The study subjects included 63 current and former aluminum potroom workers and a group of 37 cast house and carbon facility workers. While the potroom workers had higher prevalences for most of the neurologic symptoms, the only symptom for which a statistically significant higher prevalence was found was incoordination. The authors conclude that objective measures of neurologic function did not support the finding of increased neurologic symptom prevalences. The findings do not support the idea that neurologic effects among potroom workers at this facility are related to the working environment in the potrooms.
