| acute toxicity and effects analysis of endosulfan sulfate to freshwater fish species. | endosulfan sulfate is a persistent environmental metabolite of endosulfan, an organochlorine insecticide-acaricide presently registered by the united states environmental protection agency. there is, however, limited acute fish toxicity data for endosulfan sulfate. this study determines the acute toxicity (lc₅₀s and lc₁₀s) of endosulfan sulfate to three inland florida native fish species (mosquitofish [gambusia affinis]; least killifish [heterandria formosa]; and sailfin mollies [poecilia latipi ... | 2010 | 21127850 |
| evaluation of water quality threats to the endangered okaloosa darter (etheostoma okaloosae) in east turkey creek on eglin air force base. | the threatened okaloosa darter (etheostoma okaloosae) is found almost exclusively on the eglin air force base in the choctawhatchee bay watershed of florida. portions of this limited habitat are threatened with soil erosion, altered hydrology, and impaired water quality. in the present study, general water quality parameters (i.e., dissolved oxygen, specific conductance, ph, temperature, relative turbidity, and primary productivity) were characterized in east turkey creek, which is a body of wat ... | 2012 | 22326655 |
