Abstract
|
|
|
This study was designated for the investigation of the alteration of absorption and excretion fo lead after brief exposure to inorganic lead with 101 control group(male; 79, female;22) who had never exposed to lead and 107 (male;82, female;25) who had exposed to lead from 4days to 23 days after employment at storage battery factory.
The blood and urine lead level of both groups were analyzed in accordance with the duration of lead exposure and with the section of study group.
The results were as follows:
1. It was found that there was no difference of urine lead level between control group and study group in spite of higher lead exposure for study group after 4 or 7 days exposure to lead, but there was a statistically significant difference between two groups after exposure to lead for 12 or 23 days.
2. All but 4 day exposure to blood lead level, there was no difference, but there was a statistically significant difference between two group after several days exposure to lead.
3. The higher the lead concentration of workroom was, the higher the blood lead concentration was.
4. It was found that blood and urine lead concentration had increased as high as to 80 ㎍/㎗ and 200 ㎍/ℓ, respectively, even though brief exposure to lead at higher lead concentration of workroom(0.35㎎/㎥).
