Bacteria that can help defuse highly toxic dioxin in sediments in the Passaic River – a Superfund hazardous waste site – could eventually aid cleanup efforts at other dioxin-contaminated sites around the world, according to Rutgers scientists.
Their research, published in the journal Environmental Science & Technology, needs further work to realize the full potential of the beneficial bottom-dwelling microbes.
“The bacteria-driven process we observed greatly decreases the toxicity of dioxin,” said senior author Donna E. Fennell, a professor who chairs the Department of Environmental Sciences in the School of Environmental and Biological Sciences at Rutgers University–New Brunswick.
“Our results showed that although the process is quite slow, it can be enhanced and may even have the potential to remove all toxic chlorines from the compound,” said lead author Rachel K. Dean, a Rutgers doctoral student.
