Neurobehavioural evaluation of Venezuelan workers exposed to inorganic lead.

Abstract: Objectives-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 Organisation neurobehavioural core test battery (NCTB) in a cross sectional study. Methods-The NCTB comprises a questionnaire and seven tests that measure simple reaction time, short term memory (digit span, Benton), mood (profile of mood states), eye-hand coordination (Santa Ana pegboard, pursuit aiming II), and perceptual speed (digit-s… Show more

“…However, this inconsistency disappears in a meta-analysis by Meyer-Baron and Seeber [18], which is based on the studies mentioned. The finding of unaffected reaction time by lead is in accordance with the findings of Haenninen et al [12], Maizlish et al [16] Campara et al [5] and Repko et al [22]. They are in conflict with Williamson and Teo [29].…”

“…Baker et al (1983) reported impaired verbal concept formation, memory, and visual/motor performance among workers with PbB >40 μg/dL. Similar findings were reported in a cohort of 43 Venezuelan workers from a lead smelter who had a mean-employment duration of 4 years and a mean PbB of 42 μg/dL (Maizlish et al 1995). The authors observed a significant association between altered mood states and current, peak, and timeweighted average (TWA) blood lead levels.…”

“…Many human and experimental studies during past decades have demonstrated adverse effects on the central nervous system (CNS) after chronic exposure to inorganic lead [3][4][5]. Neuropsychological symptoms and cognitive deficits have been the main manifestations of milder adverse effects, and although several studies have demonstrated the neuropsychological effects of current lead exposure [6][7][8][9][10][11] only a few studies have examined cognitive abilities after long-term exposure has ceased [12,13]. Results from the two latter studies are controversial, and it remains unclear whether reduced cognitive abilities from chronic low-level lead exposure are reversible or not [11].…”
