Biodegradation of Synthetic Chelates in Subsurface Sediments from the Southeast Coastal Plain

摘要: The codisposal of synthetic chelating agents [e.g., ethylenediamine-tetraacetic acid (EDTA), diethylenetriaminepentaacetic (DTPA), and nitrilotriacetic (NTA)] radionuclides has been implicated in increased radionuclide transport the subsurface environment. Microbial transformations chelates are currently unknown, but could influence chelate persistence thus alter radionuclides. Surface soil sediments from five formations (36- to 376-m depth) were collected near Allendale, SC
