Over 500 faeces of otter (Lutra lutra) from Britain, with a small sample from northeast Greece, were analyzed for Cd, Hg and Pb. A small sample of mink (Mustela vison) faeces was also analyzed. Mean concentrations of metals (mg kg-1 dry weight) in otter faeces ranged from 1.53 to 3.97 Cd, 0.25 to 0.74 Hg and 12.4 to 20.9 Pb. Mink faeces generally contained less Cd and Hg, but more Pb. Metal concentrations in faeces may reflect both natural and anthropogenic sources. Estimates of daily Cd and Pb intake were made from faecal concentrations and these were in good agreement with concentrations in major fish prey. The estimates of daily Cd and Pb intake are high, but nevertheless most samples came from thriving otter populations. The value of faecal analysis in assessing metal burdens during surveys of otters is discussed.
对来自英国的500多份水獭（欧亚水獭）粪便以及一小份来自希腊东北部的样本进行了镉、汞和铅含量分析。还对一小份貂（美洲水貂）粪便样本进行了分析。水獭粪便中金属（毫克/千克干重）的平均浓度范围为：镉1.53至3.97、汞0.25至0.74、铅12.4至20.9。貂粪便中的镉和汞含量通常较低，但铅含量较高。粪便中的金属浓度可能反映自然和人为来源。根据粪便浓度估算了每日镉和铅摄入量，这些估算值与主要鱼类猎物中的浓度高度吻合。每日镉和铅摄入量估算值较高，但大多数样本来自数量不断增长的水獭种群。文中讨论了粪便分析在水獭调查中评估金属负荷方面的价值。
