作者研究了现场空气铅浓度接近容许浓度0.15mg/m~3时,工人血铅、尿δ-氨基-γ-酮戊酸(δ-ALA)的变化及其生物学意义。选择某蓄电池厂53名工人,连续7年测定其尿中δ-ALA(每年二次)、相应车间空气铅浓度(每年一次),及近4年来的血铅水平(每年一次)。尿δ-ALA和血铅每年及历年的结果皆呈良好
The authors studied the changes of blood lead and urine δ-ALA in workers and their biological significance when the concentration of lead in air was close to the allowable concentration of 0.15 mg / m ~ 3. 53 workers from a battery factory were selected and their δ-ALA in urine (twice a year), air lead concentration (once a year) in the corresponding workshop and blood lead level (once a year) in the past 4 years were measured continuously for 7 years. The results of urinary δ-ALA and blood lead were good both yearly and calendar year
