title: Neurobehavioural effects of industrial mixed solvent exposure in Chinese printing and paint workers.
abstract: Neurobehavioural symptoms and performance tests were evaluated in a group of 78 workers exposed to mixed organic solvents (printers, paint sprayers and paint production workers) and a referent group of 145 unexposed subjects (nonproduction factory workers and volunteer postal workers). Both groups were administered a structured symptoms questionnaire and eight neurobehavioural tests for psycho-motor function, visual and auditory memory. An excess of symptoms of fatigue, irritability, depression, poor memory, sleep disturbances and symptoms suggestive of autonomic dysfunction was found in the exposed group. Neurobehavioural test performance was generally worse, and performance on tests of psycho-motor function (choice reaction test and digit symbol) and auditory memory (digit span and associate learning) was significantly poorer in the exposed group. The findings support the view that apparently healthy and actively employed workers exposed to mixed solvents show neurobehavioural deficits.
