DDT

The pesticide DDT has been found in sediment samples from the Escambia River and its adjacent wetlands, a post-doctoral research associate at the University of West Florida has discovered.

Dr. Geoffrey Marchal, who was hired in April to begin the research, is now testing those sediment samples to see how readily available the pollutant is to the many diverse species that inhabit the bay.

“That’s the big concern,” Marchal said. “If the DDT in the sediment is bioavailable and can go through the food chain, then we have an issue.”
