Abstract

Stormwater detention ponds remove pollutants e.g. heavy metals and nutrients from stormwater runoff. These pollutants accumulate in the pond sediment and thereby become available for bioaccumulation in fauna living in the ponds. In this study the bioaccumulation was investigated by fauna samples from 5 wet detention ponds for analyses of heavy metal contents. Five rural shallow lakes were included in the study to survey the natural occurrence of heavy metals in water-dwelling fauna. Heavy metal concentrations in water-dwelling fauna were generally found higher in wet detention ponds compared to rural shallow lakes.KeywordsHeavy MetalHeavy Metal ContentStormwater RunoffUrban StormwaterDetention PondThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
