Neuropsychological effects among workers exposed to organic solvents.

Objective: To assess neuropsychological performance among workers at a paint factory in Mexico City.

Materials And Methods: During 2004 and 2005 we assessed the neuropsychological performance of 208 workers who were exposed to organic solvents at a paint factory, mainly toluene and xylene. We categorized workers into low and high exposure groups using a cumulative index for toluene, based on times spent in different tasks.
