This study evaluated the effect of sex on the accumulation of arsenic, cadmium, lead, copper and zinc in calves. Samples of liver, kidney, muscle and blood of 312 animals (127 females and 185 males) were analysed after acid digestion using atomic absorption spectrophotometry (AAS). Arsenic was determined by AAS interfaced with continuous flow hydride generation, cadmium and lead by graphite furnace, and copper and zinc by flame. Females accumulated more cadmium, copper and zinc in kidneys than did males. The zinc blood levels in females were higher than in males, whereas copper in liver was higher in males than in females. In the case of arsenic and lead, no significant statistical differences between males and females were found.
本研究评估了性别对犊牛体内砷、镉、铅、铜和锌蓄积的影响。采用原子吸收分光光度法（AAS）对312只动物（127只雌性和185只雄性）的肝脏、肾脏、肌肉和血液样本进行酸消解后分析。砷通过与连续流动氢化物发生联用的AAS测定，镉和铅通过石墨炉测定，铜和锌通过火焰测定。雌性肾脏中镉、铜和锌的蓄积量高于雄性。雌性的血锌水平高于雄性，而雄性肝脏中的铜含量高于雌性。对于砷和铅，未发现雄性和雌性之间存在显著统计学差异。
