2002年，在空中施用溴敌隆（一种抗凝血灭鼠剂）以控制爆发性布氏田鼠（Microtus brandti）种群后，蒙古发生了数百起非目标野生动物死亡事件。为了澄清二次中毒是否可能导致这些死亡，在蒙古进行了一项实地研究，以测量暴露于两种浓度（50和500毫克/公斤）溴敌隆处理的小麦后田鼠体内的溴敌隆残留量。溴敌隆在田鼠体内的总负荷量（2.65μg±0.53SE）和肝脏负荷量（1.74μg±0.33SE）与对照组（13.70μ g ± 3.82SE）存在显著差异（P<0.05）。地面死亡的田鼠体内溴敌隆的总含量（32.35μg±17.98SE）显著高于诱捕的活田鼠（5.18μg±1.40SE）（p<0.05）。这些结果是有价值的二次中毒风险的清道夫和捕食者从大规模的溴敌隆中毒行动的类型在蒙古进行的未来评估。
In 2002, hundreds of non-target wildlife deaths occurred in Mongolia following aerial applications of bromadiolone, an anticoagulant rodenticide, to control eruptive Brandt’s vole (Microtus brandti) populations. To clarify whether secondary poisoning could have contributed to these deaths, a field study was undertaken in Mongolia to measure bromadiolone residues in voles following exposure to two concentrations (50 and 500mg/kg) of bromadiolone-treated wheat. The two treatments produced different total burdens (2.65μg±0.53SE and 13.70μg±3.82SE, respectively) and liver burdens (1.74μg±0.33SE and 8.81μg±2.33SE, respectively) of bromadiolone in voles (both p<0.05). Total burdens of bromadiolone in voles found dead above ground were higher than those of live-trapped voles (32.35μg±17.98SE versus 5.18μg±1.40SE, respectively; p<0.05). These results are valuable for future assessments of secondary poisoning risk to scavengers and predators from large-scale bromadiolone poisoning operations of the type undertaken in Mongolia.
