| evaluation of ecologically relevant bioassays for a lotic system impacted by a coal-mine effluent, using isonychia. | many studies investigating the ecotoxicological impacts of industrial effluents on fresh-water biota utilize standardized test species such as the daphnids, ceriodaphnia dubia, daphnia magna, and the fathead minnow, pimephales promelas. such species may not be the most predictive or ecologically relevant gauges of the responses of instream benthic macroinvertebrates to certain stressors, such as total dissolved solids. an indigenous species approach should be adopted, using a sensitive benthic c ... | 2004 | 15195819 |
| in vivo and in vitro neurochemical-based assessments of wastewater effluents from the maumee river area of concern. | wastewater treatment plant (wwtp) effluents contain potentially neuroactive chemicals though few methods are available to screen for the presence of such agents. here, two parallel approaches (in vivo and in vitro) were used to assess wwtp exposure-related changes to neurochemistry. first, fathead minnows (fhm, pimephales promelas) were caged for four days along a wwtp discharge zone into the maumee river (ohio, usa). grab water samples were collected and extracts obtained for the detection of a ... | 2016 | 26736051 |
| assessment of the ecological effects of arsenic on a southern ohio, usa stream. | davis creek is a southern ohio, usa stream that receives a permitted discharge from the belpre elastomers plant (bep). a sediment quality triad investigation of davis creek was conducted over a 2-y period that included sediment and surface water chemistry measurements, toxicity tests of whole sediment, interstitial and surface water, and benthic and artificial substrate community assessments. the concentration of arsenic in surface and interstitial water was below united states environmental pro ... | 2009 | 19055317 |
