Trace elements, which may have harmful health effects, are present in the environment at varying concentrations. In Albania, data on exposure risks are limited. This study aimed to assess and compare the concentrations of various trace elements (aluminum, arsenic, boron, calcium, cadmium, chromium, copper, iron, potassium, magnesium, manganese, nickel, lead, and zinc) in the hair of cattle and sheep raised in Central Albania (Tirana and Elbasan Counties). Hair samples were collected from 25 cattle and 25 sheep per county and analyzed using inductively coupled plasma-optical emission spectroscopy. Zinc concentrations were significantly higher in cattle than in sheep ( = 0.029), while no differences were observed between counties ( > 0.05), indicating similar environmental conditions. Copper (17.84, 95%CI: 13.63-16.34 and 15.84, 95%CI: 14.00-17.69 mg/kg in cattle, and 15.58, 95%CI: 13.61-17.56 and 14.14, 95%CI: 12.07-16.20 mg/kg in sheep, in Elbasan and Tirana County, respectively), arsenic (2.08, 95%CI: 1.45-1.21 and 1.51, 95%CI: 1.19-1.81 mg/kg in cattle, 1.73, 95%CI: 1.38-2.07 and 1.39, 95%CI: 1.02-1.75 mg/kg in sheep, in Elbasan and Tirana County, respectively), and cadmium (2.36, 95%CI: 1.63-2.07 and 2.00, 95%CI: 1.68-2.32 mg/kg in cattle, 2.00, 95%CI: 1.59-2.40 and 1.71, 95%CI: 1.39-2.02 mg/kg in sheep, in Elbasan and Tirana County, respectively) concentrations exceeded the values reported in the literature, likely due to contamination from local mining and metal processing activities. Further research is needed to determine the sources of contamination and assess potential risks to animal and human health.
可能对健康产生有害影响的微量元素在环境中的浓度各不相同。在阿尔巴尼亚，关于接触风险的数据有限。本研究旨在评估和比较阿尔巴尼亚中部（地拉那县和爱尔巴桑县）饲养的牛和羊毛发中各种微量元素（铝、砷、硼、钙、镉、铬、铜、铁、钾、镁、锰、镍、铅和锌）的浓度。每个县从25头牛和25只羊身上采集毛发样本，并使用电感耦合等离子体发射光谱法进行分析。牛的锌浓度显著高于羊（ = 0.029），而各县之间未观察到差异（ > 0.05），表明环境条件相似。在爱尔巴桑县和地拉那县，牛的铜浓度（分别为17.84，95%置信区间：13.63 - 16.34和15.84，95%置信区间：14.00 - 17.69毫克/千克）以及羊的铜浓度（分别为15.58，95%置信区间：13.61 - 17.56和14.14，95%置信区间：12.07 - 16.20毫克/千克）、砷浓度（分别为2.08，95%置信区间：1.45 - 1.21和1.51，95%置信区间：1.19 - 1.81毫克/千克，牛；1.73，95%置信区间：1.38 - 2.07和1.39，95%置信区间：1.02 - 1.75毫克/千克，羊）以及镉浓度（分别为2.36，95%置信区间：1.63 - 2.07和2.00，95%置信区间：1.68 - 2.32毫克/千克，牛；2.00，95%置信区间：1.59 - 2.40和1.71，95%置信区间：1.39 - 2.02毫克/千克，羊）均超过了文献报道的值，这可能是由于当地采矿和金属加工活动造成的污染。需要进一步研究以确定污染源并评估对动物和人类健康的潜在风险。
