本文测定了生活在夏威夷三个岛屿（奥帕提亚岛、毛伊岛和夏威夷）上的8个地区的小印度猫鼬的肝、肾、脑、毛发、肌肉和胃内容物中的26种微量元素的含量，包括必需元素（Mg、Ca、Cr、V、Mn、Fe、Co、Ni、Cu、Zn、Se、Sr和Mo）和有毒元素（As、Cd和Pb）。不同生境中某些金属元素的含量存在显著差异。夏威夷澳洲坚果园猫鼬体内镉含量相对高于其他7个地区。铅浓度的猫鼬从Ukumehame射击场显着高于其他地区。与来自其他国家的猫鼬报告的数据相比，来自夏威夷群岛的猫鼬大脑中的铅浓度较高，但在肝脏和肾脏中观察到几乎相似的水平。有趣的是，来自Ukumehame射击场的三个样本的脑铅浓度超过了3.79 μ g g（-1），这是在先前的研究中给药后引起一些中毒症状的大鼠脑铅平均水平。此外，两个胎儿表现出较高的脑铅浓度比他们的母兽。这些结果促使我们考虑来自射击场作业的铅对小印度猫鼬和其他动物物种（包括人类）的潜在暴露和健康影响。
Concentrations of 26 trace elements including essential (Mg, Ca, Cr, V, Mn, Fe, Co, Ni, Cu, Zn, Se, Sr and Mo) and toxic (As, Cd and Pb), were determined in the liver, kidney, brain, hair, muscle, and stomach contents of the small Indian mongooses inhabiting eight areas on three Hawaiian Islands, Oahu, Maui and Hawaii. There were significant differences in concentrations of some metals among the habitats. Cadmium concentrations in mongooses from the macadamia nut orchards on Island of Hawaii were relatively higher than those in populations from other seven areas. Lead concentrations in mongooses from the Ukumehame firing range were significantly higher than those from other areas. Compared to data reported in mongooses from other countries, Pb concentrations in the brain were higher in the animals from Hawaiian islands, but almost similar levels were observed in the liver and kidney. Intriguingly, brain concentrations of Pb in three specimens from the Ukumehame firing range exceeded 3.79 mu g g(-1), which was the mean cerebral Pb level in rats that caused some toxic symptoms after administration in the previous study. Furthermore, two fetuses exhibited higher brain Pb concentrations than each of their dams. These results prompted us to consider the potential exposure and health effects of Pb derived from firing range operations on the small Indian mongoose and other animal species including human.
