Abstract
Fauna caught in three stormwater ponds, two receiving highway run-off and one receiving runoff from a center for trucks, was analyzed for copper, iron, zinc, cadmium, chromium, and lead. The fauna was monitored from March to October with 1-month intervals to evaluate seasonal trends in bioaccumulation. The results were compared with similar results from two natural shallow lakes of the same region. The study showed that there was some tendency for copper and also to some degree for other metals to be present in slightly higher concentrations in fauna of the ponds. There was, however, no clear seasonal trend in concentrations when looking at individual species or groups of species. The number of species caught in ponds and lakes was more or less identical, which together with an only slightly elevated heavy metal content of the fauna supported that stormwater ponds can contribute positively to the aquatic biodiversity of a region.
