We analysed micronuclei in brown trout Salmo trutta specimens sampled in the Trubia River, upstream and downstream of the emissions from a Spanish military factory to assess genotoxicity risks derived from military wastes. A significant exponential increase in micronuclei counts was found in fish living downstream of the military wastes with respect to fishes inhabiting upstream areas of the same river. In comparison, we only found a linear increase in micronuclei counts in a control stream where an old military factory had been demolished 6 months before sampling. This difference suggests that active discharge of armament factory wastes can directly induce micronuclei and therefore represents a genotoxic risk for the ecosystem.
我们分析了在西班牙一家军工厂排放源上游和下游的特鲁维亚河中采集的褐鳟样本中的微核，以评估军事废物产生的遗传毒性风险。结果发现，与生活在同一条河上游区域的鱼类相比，生活在军事废物下游的鱼类微核计数显著呈指数增长。相比之下，在一个对照溪流中，我们只发现微核计数呈线性增加，该溪流中的一家旧军工厂在采样前6个月已被拆除。这种差异表明，军工厂废物的持续排放可直接诱发微核，因此对生态系统构成遗传毒性风险。
