The response characteristics of an aquatic biomonitor that detects toxicity by monitoring changes in bluegill (Lepomis macrochirus Rafinesque) ventiliatory and movement patterns were evaluated in single chemical laboratory studies at concentrations near the 96-h LC5O concentration and at the ElLA Tox-Oregon Workshop in sequential tests of multiple unknown samples. Baseline data collected prior to exposure allows each fish to serve as its own control. When at least 70% of exposed ...
Water chlorination is a standard treatment for ensuring the safety of public drinking water. One drawback to this beneficial practice is the generation of drinking water disinfection by-products (DWDB), some of which have been implicated as causing adverse human health outcomes. In this article, we report the results of 96 hours of developmental toxicity tests with embryos of the South African clawed frog 'Xenopus laevis' used to evaluate four individual ...
