A comparison of the metal content of some benthic species from coastal waters of the Florida panhandle using high resolution inductively coupled plasma mass spectrometry (ICP-MS) analysisArch Environ Contam Toxicol (2003)
AbstractBenthic marine invertebrates, sediment and water from several locations along the Florida panhandle coast from St. Joseph Bay in the west to the mouth of the Wakulla River in the east, including from several river estuaries, were analyzed by double focusing ICP-MS (Finnigan MAT ELEMENT) FOR Cd, Hg, Pb, Cu, Zn, and As. All were detected in all samples. Sponges generally contained higher levels of Cd than other species. Microciona prolifera sponges from St. Joseph Bay had higher As levels (8.1-13.6 ug/g dry weight) than sponges collected from Dickerson Bay or Appalachee Bay (2.2-9.7) and higher Cd levels than that of a single Microciona specimen collected from Dickerson Bay (0.29). Water content of As was about 20-30x higher in St. Joseph bay than in any other location, and sediment levels were about 9x higher. Cu and Zn were higher in organic sediment from St. Joseph bay than they were in other areas. The Pb content of several sponge species and two of tunicates was considerably higher than in other species. The uptake of most metals in the study (except As) appeared to be affected by the metal, genus, species, and location as much as by levels in either water or sediment. In general, sponges and tunicates seemed to accumulate higher levelsthan most other species, possible a function of high filtration rates. The ICP-MS method for environmental studies but the instrument requires considerable maintenance.
