| Summary: | 碩士 === 高雄醫學院 === 公共衛生學研究所 === 84 === There has been concern for many years over lead as a
potential hazard inworking environment. The laborer''s health is
threatened by lead while theyuse it. Therefore, it is more and
more important to protect them who work inthe environment
polluted by lead. We have surveyed one lead-battery factory
and one litharge factory in Ka-ohsiung and Pingtung area. After
the first observation, all of 55 and 103workers of the two
factories were our study samples. The study included env-
ironmental exposure assessment, questionnaire interview, and
blood-leadmeasurements. We used personal sampling pump to
collect environmental samplesto estimate 4-hour average
concentrations by Flame Atomic Adsorption Spectr-ophotometer.
The recovery of this self-assessment questionnaire survey is
onehundred percent. 10 ml blood was drawn and kept in lead-free
tubes for blood-lead measurements by Occupational Health center
of Kaohsiung Medical College. The analysis results show that
the lead levels of environmental exposure atthe lead-battery
factory are between 0.033 to 3.867 mg/m3(mean : 1.027(1.016mg/
m3). The maximum data 3.867 mg/m3 was measured in cutting area.
The otherareas except office in the factory, the lead levels
exceed the PEL-TWA of 0.1mg/m3. And blood-lead concentrations
are between 10.30 to 91.00 g/dl (mean:45.99±19.75 g/dl for man,
28.63±15.50 g/dl for woman),and the standard valueof
surveillance system is 40 g/dl for man and 30 g/dl for woman.
According tothe questionnaire data, there is a significant
correlation between blood-leadand job characteristics,working
area, lodging in the factory or not, diet inthe factory or not,
and taking a bath or not after finishing their work (p<0.05) .
The environmental exposure levels of lead at the litharge
factory are between0.054 to 1.053 mg/m3(mean : 0.286(0.249 mg/
m3). The maximum data 0.397 mg/m3 wasmeasured in smelting lead
area. The blood-lead concentrations are between 2.80to 82.20 g/
dl (mean: 28.78±15.30 g/dl for man, 11.60±11.51 g/dl for
woman).From the questionnaire data, there is only a significant
correlation betweenblood-lead and job characteristics (p<0.05).
