Toxicological evaluation of water from stormwater ponds using Xenopus tropicalis embryos
Pohl, Johannes; Örn, Stefan; Norrgren, Leif; Carlsson, GunnarAbstract
The establishment of stormwater ponds for treatment of runoff water can be beneficial for amphibians due to creations of new habitats which often develop vegetative characteristics similar to that of natural wetlands. These ponds might help to promote stability in amphibian populations if the benefits of creation of new habitats exceed the risk for toxic impact. In the present study, Swedish stormwater ponds were searched for larval amphibians. Further, the impact of stormwater quality on embryo development was tested using Xenopus (Silurana) tropicalis. Data suggest that most of the studied stormwater ponds had water of proper quality for promoting amphibian embryo development. However there were sites in which the water caused premature hatching and/or reduced heart rate in X. tropicalis embryos. Pollutant toxicity might be one explanation for sublethal effects caused by some of the stormwater samples. In a majority of ponds, no amphibian larvae were detected and this may partly be explained by toxic compounds in the waters.Keywords
