Heavy Metals in Organic-Rich Muds of the Neuse River Estuarine System

摘要

A regional sampling grid was developed within the Albemarle estuarine system thatincluded 178 short core (<0.5m), 19 long core (<6m), and 22 surface sample sites. These 219 sites represent all possible geographic and geologic conditions, as well as major anthropogenic sources of pollutants throughout the Albemarle system. From these cores, 378 subsamples have been completely processed and analyzed in the sediment laboratory for grain size and sediment composition; consequently, all field work and sediment analyses have now been completed on these samples. Chemical analyses for major, minor, and trace elements are complete on 247 of these samples (66%) at this point in time. The remaining one third of the samples are presently in the anlaytical mill. Consequently, the results of both the sediment and chemical data are only in early stages of formulation and synthesis.
