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.

Abstract	This study investigated neuropsychiatric changes associated with lead exposure. Persons with past and current exposure to lead were compared to a demographically similar non-exposed control group. That is, between 1981 and 1984, lead-exposed and non-exposed workers were evaluated as part of an epidemiological study of lead conducted at the University of Pittsburgh. lead-exposed workers were members of District 10, United Steel Workers of America, and worked at three industrial plants in Eastern Pennsylvania (approximately 200 miles from Pittsburgh) that manufactured lead batteries for automobiles and motorcycles. At the initial testing, subjects were randomly selected from company lists: the lead-exposed workers had a mean age of 35 (range 21-60) and blood lead levels averaged 40 pg/dl with peak blood levels around 90 pg/dL. Demographically similar non-exposed blue collar workers were also seen for the initial study. For the current study we attempted to recruit as many subjects as possible who were initially tested approximately 20 years ago and to repeat the neuropsychological test battery. In addition , information was collected on current and past psychiatric history, and current blood lead levels (BLL) were obtained. Finally, bone concentration of lead was determined with x-ray fluorescence (XRF) - a procedure that was not available 20 years ago.
