A new bioreactor system that serves up pollutants to "hungry" bacteria promises to clean up "unprecedented" levels of toxic organic chemicals classified as "priority pollutants" by the U.S. Environmental Protection Agency, according to Canadian researchers. The scientists envision its use in cleaning up contaminated sites and to get rid of old chemical supplies.
A new, more effective method for destroying potentially deadly toxins called microcystins that can be found in drinking water has been announced by researchers in Scotland.
