本文介绍不同国家无铅作业史居民发铅的含量(表Ⅰ)。根据大多数作者的意见把发铅含量30毫微克/克做为正常人的生理水平。发铅采用原子-光谱吸收法测定。作者对不同程度受到铅损害病人血、尿、发铅含量做比较(表Ⅱ),指出从接触铅后,经过35天头发中出现铅。和各种生物液比较头发中畜积铅的能力最强;当尿铅含量在正常值上限时,而发铅含量超过正常值上限的四倍,血铅、尿铅浓度平均增长1.5倍的轻度铅中毒时发铅含量比对照组增加28
This article describes the lead content of lead-free household inhabitants in different countries (Table I). According to the opinion of most authors hair lead content of 30 ng / g as the normal physiological level. Lead was determined by atomic absorption spectrometry. The authors compared the levels of lead, blood, urine and hair in varying degrees (Table II) for lead-exposed patients, noting that lead appeared after 35 days of hair exposure from exposure to lead. Compared with various biological fluids, the capacity of lead in animal hair is strongest. When the content of lead in urine is at the upper limit of normal, the content of lead in hair exceeds four times the upper limit of normal and the blood lead and urine lead increase 1.5 times on average Lead poisoning lead content than the control group increased 28
