New research from Michigan State University has shown for the first time that activated carbon – a substance widely used in water purification – can help eliminate the health risks associated with soils, sediments and surface water polluted by highly toxic dioxins.Stephen Boyd, a University Distinguished Professor in the MSU Department of Plant, Soil and Microbial Sciences, led the study, which is published online in the journal Environmental Toxicology and Chemistry. The research looked specifically at soil and freshwater ecosystems that had been contaminated mainly through the industrial manufacture of pesticides and other chemicals.
