Abstract
|
|
|
In order to investigate that blood lead levels of lead exposed workers is associated with decreased performance in neurobehavioral tests in adults, we investigate 78 workers in a battery industry.
Three items among neurobehavioral core test battery of World Health Organization, including digit span, Santa ana dexterity, digit symbol were administered to workers occupationally lead exposed workers by operational guide for the WHO neurobehavioral core test battery. Blood lead (PbB) and zinc protoporphyrin in whole blood (ZZP) were selected as an index of lead exposure. Detailed occupational history such as exposed agent, age, work duration, smoking and drinking habits, were recorded as confounding factors.
After controlling age, the results of digit span and digit symbol among the neurobehavioral tests were significant contributed by PbB.
