Speciation and Availability of Metals in Wetlands

Sediment samples were collected from a shallow wetland, Dead Stick   Pond, located in South Chicago, at the southern end of Lake   Michigan. Grab samples were collected by hand from the top 1 -12 cm   of the sediment, placed into plastic specimen cups with minimal   headspace, and preserved into airtight containers flushed with   nitrogen gas to minimize oxidation.    The principal objectives of this project were to:   1) determine the reliability of the most common methods used for   determining the speciation of metal in sediments by contrasting   results with a direct speciation method based on synchrotron   radiation, and;   2) use this direct method to determine how metals and their chemical   species are spatially distributed in sediments.     (sediment); (mercury); (Hg); (toxic metal); (toxic metals);   (sediments); (Illinois); (Lake Michigan); (human health); (fish   consumption advisories); (fish consumption advisory); (fish   consumption); (chemicals of concern); (chemical of concern)
