Reusing biosolids to decrease bioavailability of persistant organic pollutants (POPs)

Principal Investigator(s) 

Several highly persistent organic pollutants have been extensively used by industry and agriculture. While many of them have been banned, many sites still contain levels that pose ecological risks. Here, we are investigating if adding organic amendments will reduce the bioavailability of POPs, such as DDT, in soil. We use a combination of field and laboratory studies. If proven efficient, it will be a much more environmentaly friendly form of remediation than methods currently used. We are also working on the development of a chemical methodology to determine POPs bioavailability and thus, potential risk. More information about this project is available online.
