X-ray fluorescence analysis of lead in bone.
Immunoglobulins (Ig) and some complement components (C) were quantified in sera from patients with gastric carcinoma before surgery and at regular intervals during a 5-year follow-up.
متن کاملBone lead concentrations assessed by in vivo X-ray fluorescence.
The assessment of past chronic lead exposure is difficult. Chronic lead burden is not always correctly assessed using laboratory-based tests that are useful for acute or recent exposures. We describe a case of suspected chronic lead exposure that illustrated the need for improved and possibly noninvasive methods to determine cumulative lead body burden. X-Ray fluorescence (XRF) is discussed as ...
متن کاملBone lead measured by X-ray fluorescence: epidemiologic methods.
In vivo X-ray fluorescence (XRF) measurement of bone lead concentration (XRF) has emerged as an important technique for future epidemiological studies of long-term toxicity. Several issues germane to epidemiologic methodology need to be addressed, however. First, sources of variability in measurements of bone lead need to be quantified, including imprecision related to the physical measurement ...
متن کاملEquipment design issues for the in vivo X-ray fluorescence analysis of bone lead.
Several groups have reported the development of systems, based on the principle of X-ray fluorescence, for the in vivo measurement of bone lead concentrations. These systems have used the detection of either the characteristic L or K X-rays resulting from excitation by a suitable photon source. This paper examines design issues related to the development of these systems. These design issues ar...
متن کاملCalculating the uncertainty in lead concentration for in vivo bone lead x-ray fluorescence.
A revised mathematical treatment of the calibration line intercept has been published for in vivo bone lead measurements using 109Cd-based K-shell x-ray fluorescence. The revised calibration line treatment prompts changes, presented herein, to the method for calculating the measurement uncertainty.
