| description | Implemented for decades as part of the ‘best management practices (BMPs)’ for controlling urban runoff impacts on receiving waters, stormwater management ponds (SMPs) have been increasingly viewed as potential habitats for urban wildlife. However, since SMPs are subject to a lot of environmental constraints, research toward assessing their ecological quality and their actual benefits as habitats for biota is needed. In this study, the sediment toxicity of eight SMPs located in Southern Ontario, Canada was assessed using the sediment quality triad (SQT) approach. Sediment samples were collected for chemical, ecotoxicological and biological analyses. An oligochaete-based index approach (Oligochaete Index of Lake Bioindication and percentage of pollution-sensitive species) was used as the biological endpoint and integrated into a weight-of-evidence approach to assessing the general sediment quality of the ponds. Our results showed that (i) heavy metals in the sediment and (ii) chloride concentrations in the sediment interstitial water caused detrimental effects on the ecological quality of the sediments in the ponds studied. The oligochaete indices applied in this study showed value as biological endpoints to be integrated into the SQT and used for setting up sediment ecological quality goals.
HIGHLIGHTS
An oligochaete-based index approach was used as a line of evidence in the SQT to assess the ecological quality of eight stormwater ponds in Southern Ontario.;
High concentrations of chloride in pore water and of heavy metals in the sediment matrix were linked to detrimental effects.;
The oligochaete-based index approach was used to set up ecological quality goals for stormwater pond sediment.; |
