| toxicity of road salt to nova scotia amphibians. | the deposition of chemical pollutants into roadside wetlands from runoff is a current environmental concern. in northern latitudes, a major pollutant in runoff water is salt (nacl), used as de-icing agents. in this study, 26 roadside ponds were surveyed for amphibian species richness and chloride concentration. acute toxicity tests (lc(50)) were performed on five locally common amphibian species using a range of environmentally significant nacl concentrations. field surveys indicated that spotte ... | 2009 | 18684543 |
| arsenic species and uptake in amphibians (rana clamitans and bufo americanus). | total arsenic concentrations and the chemical form, or species, of arsenic were determined in amphibians (rana clamitans and bufo americanus) collected from a site with elevated arsenic concentrations in nova scotia, canada. frog legs had significantly elevated total arsenic concentrations at a contaminated site when compared with a nearby background site and a calculation of the estimated daily intake rates of arsenic indicates that both diet (invertebrate intake) and water absorption are impor ... | 2013 | 23788261 |
