BACKGROUND
The current study determines the relationship between heavy metals and alpha particles emission rates in milk and blood of lactating women in Diwanyah, Iraq.
METHODS
Heavy metals and alpha particle emission rates have been measured using an Atomic Absorption Spectrophotometer and a Nuclear Track Detector.
RESULTS
The results show that Pb, Cd, and Cu in milk are 0.2239 ± 0.0007 ppm, 0.0156 ± 0.0001 ppm, and 0.1811 ± 0.0006 ppm, respectively. Pb, Cd, and Cu in the blood were 0.0898 ± 0.0008 ppm, 0.0432 ± 0.0010 ppm, and 0.1729 ± 0.0004 ppm, respectively. The highest alpha particle emission rate was found to be in age interval from 23 y to 28 y in milk, while the highest alpha particle emission rate was found to be in the age interval from 35 y to 40 y.
CONCLUSIONS
This study concludes that no statistical significance between Pb, Cd, Cu and Eα in milk and blood at level 0.01. The following order of bioavailability was found with heavy metals Cu < Pb < Cd.
背景
本研究确定了伊拉克迪瓦尼亚哺乳期妇女的牛奶和血液中重金属与α粒子发射率之间的关系。
方法
使用原子吸收分光光度计和核径迹探测器测量重金属和α粒子发射率。
结果
结果表明，牛奶中的铅（Pb）、镉（Cd）和铜（Cu）分别为0.2239±0.0007 ppm、0.0156±0.0001 ppm和0.1811±0.0006 ppm。血液中的铅、镉和铜分别为0.0898±0.0008 ppm、0.0432±0.0010 ppm和0.1729±0.0004 ppm。牛奶中α粒子发射率最高的年龄段为23岁至28岁，而血液中α粒子发射率最高的年龄段为35岁至40岁。
结论
本研究得出结论，在0.01水平下，牛奶和血液中的铅、镉、铜与α粒子发射率之间无统计学意义。发现重金属的生物利用度顺序为铜＜铅＜镉。
