Download or read book Methods to Improve the Sensitivity of an Automated Biomonitoring System written by C. Frago and published by . This book was released on 1995 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biomonitoring system was designed to assess changes in toxicity of wastewater or surface water on a real-time basis using fish as the sensors. Previous research indicated that there were other responses in addition to the breathing rate which might be equally or more sensitive to changes in toxicity. These included fish activity (turns and episodes) and changes in the shape of the waveform generated as the fish breathes. To investigate the usefulness of these responses, four methods were used: strip-chart recordings, split-screen video techniques, Fast Fourier Transformation techniques, and a data replay software program. As a result of this research, the software of the biomonitoring system has been modified to include the additional responses which showed promise to increase the sensitivity of the system. Field testing of the system will be the next step.

Download or read book Expert System for Real Time Biomonitoring of Environmental Toxicity written by and published by . This book was released on 2002 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Automated biomonitoring systems continuously monitor water quality and provide rapid notification of developing toxicity caused by a wide range of substances. An important goal for biomonitors is to maximize sensitivity to toxicants while minimizing false alarms that may be caused by non-harmful variations in water quality. Significant improvements in toxicity detection without an increase in false alarms are possible through the use of novel data processing and neural network modeling approaches developed for an automated fish biomonitoring system. Toxicity detection is based on simultaneous analysis of ventilatory and movement behavior of a group of eight fish (bluegill, Lepomis macrochirus) and water quality parameters (pH, dissolved oxygen, temperature, and conductivity). A general neural network model of fish behavior is used that does not need to be re-calibrated for each individual fish. The model can detect abnormal patterns in fish behavior associated with toxicity with a better signal-to-noise ratio than the present statistical approach, while distinguishing between changes in fish behavior due to toxicity or water quality variations.

Download or read book Human Biomonitoring for Environmental Chemicals written by National Research Council and published by National Academies Press. This book was released on 2006-11-30 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomonitoring—a method for measuring amounts of toxic chemicals in human tissues—is a valuable tool for studying potentially harmful environmental chemicals. Biomonitoring data have been used to confirm exposures to chemicals and validate public health policies. For example, population biomonitoring data showing high blood lead concentrations resulted in the U.S. Environmental Protection Agency's (EPA's) regulatory reduction of lead in gasoline; biomonitoring data confirmed a resultant drop in blood lead concentrations. Despite recent advances, the science needed to understand the implications of the biomonitoring data for human health is still in its nascent stages. Use of the data also raises communication and ethical challenges. In response to a congressional request, EPA asked the National Research Council to address those challenges in an independent study. Human Biomonitoring for Environmental Chemicals provides a framework for improving the use of biomonitoring data including developing and using biomarkers (measures of exposure), research to improve the interpretation of data, ways to communicate findings to the public, and a review of ethical issues.
