Mercury concentrations in liver and hair tissue were determined for five species of small mammals captured near Las Vegas, Nevada, USA. These data were then used to evaluate the suitability of using hair as a noninvasive technique for determining body burdens of mercury. A total of 104 small mammals were captured and analyzed; four main species were examined and included: Dipodomys merriami, Chaetodipus penicillatus, Peromyscus eremicus, and Neotoma lepida. Mean mercury concentrations were highest in N. lepida, followed by D. merriami, C. penicillatus, and P. eremicus respectively. Positive associations were found between hair and liver taken from D. merriami (r = 0.647) and C. penicillatus (r = 0.533) indicating that hair may be a suitable indicator of body burdens in these two species.
在美国内华达州拉斯维加斯附近捕获的五种小型哺乳动物的肝脏和毛发组织中测定了汞浓度。然后利用这些数据评估将毛发作为一种非侵入性技术来测定汞身体负担的适用性。总共捕获并分析了104只小型哺乳动物；研究了四个主要物种，包括：墨氏更格卢鼠、刚毛梳齿鼠、荒漠鹿鼠和李氏更格卢鼠。汞平均浓度在李氏更格卢鼠中最高，其次分别是墨氏更格卢鼠、刚毛梳齿鼠和荒漠鹿鼠。在取自墨氏更格卢鼠（r = 0.647）和刚毛梳齿鼠（r = 0.533）的毛发和肝脏之间发现了正相关，这表明毛发可能是这两个物种中身体汞负担的合适指标。
