ABSTRACT
Our study focused on the assessment of the effects of environmental lead exposure on brain electrical
activity. Electrophysiological procedures were conducted on 92 children with Pb level of 5.9 + 3.8 µg/dL
(min.=2.3 µg/dL, max.=23.0 µg/dL). The study was performed on a blind basis, and consisted of blood lead
level measurements, standard EEG examinations, brain electric activity mapping, and psychological tests.
Results of electrophysiological assessment were correlated with the blood lead concentration (PbB). Elevated
PbB significantly correlated with: abnormal EEGs (R=0.419; p<0.001), border-line results, IQ measurement
results and difficulties in learning. In conclusion, psychological tests and electrophysiological methods were
effective in the assessment of environmental exposure of children to lead.
