Assessing Welding Fume Exposure and its Impact on Motor Function

Ernest N. Morial New Orleans Convention Center 

Welders are exposed to metal-containing aerosols with manganese (Mn) linked to motor function deficits, such as Parkinsonism. We developed refined short-term and long-term cumulative exposure indices (CEIs) using personal air sampling during a work shift and a work history questionnaire. In this study, we examine how this exposure metrics affect measurable motor impairments and provide new insights into Mn effects on the nervous system while advancing methods to assess risk in occupational settings.
