对蓄电池厂铅作业工人的检测结果表明:铅接触者除出现卟啉代谢障碍、幼稚红细胞增多外,染色体畸变率亦高于对照组;红细胞游离原卟啉和染色体畸变在无铅中毒表现的接触工人中均有升高,提示这两项指标能灵敏地反映铅的损伤。建议增加染色体畸变分析作为健康监护指标,以观察铅作业工人的遗传学效应。本文还对血铅、尿铅与卟啉代谢指标间的关系进行了相关分析。 Test results of lead workers in battery factories showed that in addition to the presence of porphyrin metabolism disorders lead, lead erythrocytosis, chromosome aberration rate is also higher than the control group; erythrocyte free protoporphyrin and chromosomal aberrations in lead-free poisoning exposure Both workers have increased, suggesting that these two indicators can sensitively reflect the lead damage. It is recommended to add chromosomal aberrations analysis as a health monitoring indicator to observe the genetic effects of lead workers. This article also related to the relationship between blood lead, urinary lead and porphyrin metabolism.
