Anaerobic Metabolism, To examine the extent of anaerobic chloroaromatic metabolism, we undertook a study in which sediments from the upper Hudson River, the lower Hudson River, and the East River were used as inoculum (33, 34). Each monochlorophenol isomer (2-, 3-, and 4-chloro-phenol, CP) and each monochlorobenzoate isomer (2-, 3-, and 4-chloroben-zoate, CB) was used as substrate. Duplicate or triplicate cultures were established under three anaerobic conditions denitrifying, sulfidogenic, and methanogenic. The initial concentration of each of the chloroaromatic compounds was 0.1 mM incubation was at 30 °C in the dark. Substrates were quantified by high-pressure liquid chromatography N2 and CH4 were analyzed by gas chromatography nitrate and sulfate were determined by colorimetric methods or by ion chromatography (33, 34).

Inoculum was obtained from the East River bordering Manhattan Island, New York, NY. Re-addition of substrate is indicated by arrows. (Adapted with permission from reference 33.

Table II summarizes the results for degradation of the CP isomers in East River cultures under sulfate-reducing conditions based on the stoichiometry in equation 11. Sulfate loss in the background controls were subtracted from the cultures to which CPs were added. As noted in Table II, the measured sulfate depletion corresponded to that calculated and provided evidence that CP metabolism was coupled to sulfate reduction. In these studies sulfate reduction is supported by two additional experimental observations. First, molybdate, which is a specific inhibitor of microbial sulfate reduction, was documented to stop the CP degradation. Active controls that did not receive molybdate continued to degrade CP. Second, radiolabeled 35S042 formed 35 S2 in active cultures and not in control cultures (33).

The tide advances up the Connecticut and the Housatonic Rivers as a progressive wave (Le Lacheur and Sammons, 1932). Tides and circulation in the Thames River are described by Tolderlund (1975). The East River is a tidal straight with most of its tidal prism derived from New York Harbor (Bowman, 1976a). 

Long Island Sound is connected to the sea by three passes at its eastern end and by the East River (through New York Harbor) at its western end. The principal source of fresh water entering the Sound is the Connecticut River, which enters near the eastern end, as shown in Fig. 11. Thus the Sound does not have the conventional configuration of an estuary with... 

In addition to receiving fresh water, large quantities of wastes and sediment are inserted into the Sound. The injection of sewage wastes and, for comparison, the inflow of fresh water, along the axis of the Sound is shown in Fig. 11 (after Bowman, 1975). New York City is the dominant source of wastes and, because they are inserted where the natural circulation is weakest, they represent the main cause of environmental degradation of the Sound at the present time. Bowman (1976a) has shown how this problem could be resolved by the construction of tidal locks across the East River. The principal source of sediment entering the...

Imprinted on this feature is the increase in concentration of these trace metals near metal-polluting sources such as the Housatonic River and the East River (in New York). Thus, although the association of trace metals with the fine-grained fraction is established, the complete homogenization of this fraction does not proceed fast enough to obliterate intensive local sources of metals.
