The relationship between lead in blood, lead in urine and ALA in urine during lead work.
170-
Seven workers from a battery storage plant received blood and lead and Δ-
Amino ketone acid (ALA)in urine.
These workers were randomly selected from workers employed for more than a month;
Most people have worked in the same job for several years. Thirty-
Six workers came from departments without lead exposure.
Of the three departments exposed to high exposure, the three-week rotation system exposed and the non-exposed three-week rotation system
Exposed work is applied.
Since the purpose of the study was to establish a relationship between the three parameters during the duration of the exposure, the values of these males were treated separately.
The relationship between lead and urinary ALA in the blood is best described with a curve function: ALA = 1000157 Pbb-
10985, while ALA has a straight line on the regression line of lead in urine and the regression line of lead in urine to lead in blood.
Compared to the non-rotating system department, the worker's urine lead and ALA values in the rotating system department are lower
Rotating workers with the same lead content in the blood.
During the second or third week of leadership work, all of these workers were inspected. e.
With the accumulation of lead body burden.
This system may be beneficial, especially in departments where preventive measures are difficult to install, or for notorious careless workers.
Those who showed relatively high ALA and urine lead values associated with blood lead levels were found to be workers who repeatedly had metabolic lead effects, where ALA values were rarely normal.
The mean values from different plant departments are the same as those previously studied in the storage battery plant.
Results related to the current concept of lead absorption and poisoning were discussed.
