Thus, twenty workers, whose PbB and ALAU values have been below these limits over the past two years, were selected at random at a battery plant in the State of S. Paulo, Brazil. The workers were submitted to a variation of the WHO Neurobehavioral Core Test Battery. The results were compared with those obtained for workers of a control group also chosen at random. The lead workers showed memory, mood and motor coordination disorders. Comparing these results with those obtained from the control group, a significant difference was observed (p-value < 0.02). The results indicate that the Brazilian biological exposure limits above should be reconsidered.358-363porHigher nervous activityLead poisoning, prevention and controlNeurologic manifestationsOccupational exposure, standardsleadbloodcross-sectional studyhumanmental diseaseneurologic diseaseoccupational exposureCross-Sectional StudiesHumansLeadMental DisordersNervous System DiseasesOccupational ExposureArtigo10.1590/S0034-89101996000400009S0034-89101996000400009Acesso aberto2-s2.0-00302023452-s2.0-0030202345.pdf
