||Neurobehavioural evaluation of Venezuelan workers exposed to inorganic lead
||1995, Vol.52, p.408-414. Illus. 27 ref.
||To assess neurobehavioural effects of low exposure to lead, 43 workers from a lead smelter and 45 workers from a glass factory were evaluated with the World Health Organization neurobehavioural core test battery (NCTB) in a cross-sectional study. Historical blood lead concentrations were used to classify exposure based on current, peak and time-weighted average. Although the exposed workers performed less well than the non-exposed in 10 of 14 response variables, only profile of mood states tension-anxiety, hostility and depression mood scales showed a significantly poorer dose-response relation with blood lead concentration in multiple linear regression models that included age, education and alcohol intake as covariates. The frequency of symptoms of anger, depression, fatigue and joint pain were also significantly increased in the exposed group. This study is consistent with the larger body of neurobehavioural research of low occupational exposure to lead.
