National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

The Effects of Inorganic Lead on Behavioral and Neurologic Function.

PB83135905

Publication Date	1977
Personal Author	Repko, J. D.; Jones, P. D.; Garcia, L. S.; Corum, C. R.
Page Count	106
Abstract	The effects of absorption of low concentrations of inorganic lead (7439921) (Pb) on worker behavior and neurologic function were studied. For one year, exposed and unexposed workers were subjected to performance and behavioral test measurements, neurological and electroneuromyographic examinations, and examination of biologic samples. The 140 examined workers (85 were lead exposed, 55 nonexposed) were in the storage battery manufacturing industry. The lead exposed group had a mean blood lead (PbB) of 46 micrograms per 100 milliliters, whereas the control group had 17 micrograms Pb per 100 milliliters. PbB aminolevulinic-acid-dehydrase, free erythrocyte PbB, protoporphyrin (FEP), urine lead, and aminolevulinic-acid were intercorrelated, and each measure could be predicted from the others. Except for a positive relationship between FEP and certain pure tone threshold measures, none of the biomedical indices had a significant relationship to the nerve conduction velocities (NCV) or behavioral measures.
