Abstract

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.
