in-vivo determination of lead in the skeleton after occupational exposure to lead - storage battery
Abstract: In 22 subjects, the concentration of lead in the phalanx and blood was determined, and these subjects had previously been exposed to lead at a battery storage plant that had been closed for seven years.
Measurement of bone lead concentration in vivo using vivo
Two X-ray fluorescence techniques of 57Co γ-
The source of the line is used to generate the feature-
Lead ray measured with Ge (Li)detector.
In three subjects, changes in lead concentration were measured along the front finger and lead concentration in the shin.
The lead concentration measured in the phalanx is between 20 μg/g (
Our test limit)and 118 μg/g.
It was found that the lead concentration in the phalanx increased with the increase of working time, but there was no simple relationship between the blood and the lead concentration in the phalanx.
Four subjects decreased blood lead concentration after stopping exposure.
Seven years after the end of exposure, it was found that blood lead concentrations were more dependent on daily intake of lead than release of lead in the bones.
These experimental results can be used in two-
Use the compartment model of the exchange rate given in the publication.
This model is also used to calculate the blood lead concentration that can be achieved after the bone suddenly releases lead.
A typical selection for running the hyperlink motor products are commonly a LiFePO4 battery bunch (Lithium-Iron-Phosphate).
E-bikes are becoming popular being an environmentally friendly and also wholesome means of almost sweat-free carry.
