Title Curvilinear relationship between blood lead level and reaction time
Bibliographic information May 1997, Vol.39, No.5, p.426-431. 22 ref.
Abstract A computerized simple reaction time (SRT) test was administered to 78 lead smelter workers, and the relationship between different measures of blood lead and components of SRT performance were investigated. Measures of blood lead included current blood lead (PbB) and mathematically derived blood lead fractions from the environment (PbB-env) and from bone (PbB-bn). Measures of SRT performance were obtained from 44 trials with interstimulus intervals (ISIs) ranging from 1 to 10s. A curvilinear relationship was observed between current blood lead (PbB) and median SRT; the SRT for ISIs between 6 and 10s was the preferred measure. Of the other blood lead measures, only PbB-env was related to components of SRT.
