The potential health risks and resultant disinfection by-products from certain organic compounds that are persistent in the environment have stimulated the use of alternative oxidation processes to reduce chlorine demand. Pulsed power techniques along with treatment by photocatalytic organic sensitizers and semiconductors are being evaluated to determine their efficiency in toxic chemical decomposition, volatile organic substances removal and disinfection.
Changes in behavior of aquatic animal life can indicate the existence of toxins in water supplies. Remote sensors and biosensors are being developed through Center support to assess adverse conditions in these aquatic environments. The following are aquatic toxicology-related projects that were activated in the 2006-2007 fiscal year. For descriptions of specific projects, click on those with links below.
