The 513C of fatty acids has also been used to determine sources of HMW DOM in estuaries from four different regions of the United States (Boston Harbor/Massachusetts Bay, Delaware/Chesapeake Bays, San Diego Bay, and San Francisco Bay) (Zou et al., 2004). This work demonstrated that a fraction of HMW DOM is derived from phytoplankton and bacteria, and that HMW DOM is formed from bacterial membranes and reworking of phytoplankton materials. Finally, isotopic ( 13C) discrimination between PLFA and smaller labile molecules (e.g., acetate, methane, methanol) is considerably greater (e.g., >20%o) than that found in comparison with complex substrates (Summons et al., 1994), making such distinctions even more apparent.

Seawater samples were collected at two sites and were used to study various aspects of this extraction system. New England Aquarium line water is Boston Harbor water that has been allowed to settle and is then passed through a diatomaceous earth filter. Massachusetts Bay water was collected about 40 km east-northeast of Boston in an area typical of clean coastal waters (8). 

Extensive measurements on the concentration of vanadium in Boston Harbor waters have been reported20. An average value of 3.2 0.7 pg/1 has been reported for filtered sea water. The data for Massachusetts coastal water is within agreement of other coastal areas North West Pacific Ocean, 2.6—3.5 Plymouth, England, inshore, 5—7 Plymouth, England, offshore, 2.4-2.7 Wakayama Prefecture, Japan,... 

Figure 8 Plot of Pd/AI vs. Pt/AI in bulk sediment samples from Boston Harbor ) and Massachusetts Bay ) illustrating the influence of anthropogenic PGE release in this area. Pd and Pd concentrations are normalized to Al to eliminate grain size and dilution effects. All sediments from Massachusetts Bay are uninfluenced by human activity, based on depositional age estimates and Ag analyses. Contaminated sediments from Boston Harbor are enriched in R and Pd relative to pristine sediment. This is true for absolute R and Pd concentrations as well the Pt/AI and Pd/AI data shown above. Data are from Tuit et al. (2000) Environmental Science Technology 34 927.
