Plants, seston, and sediment

Phenolic and Lignin Pyrolysis Products of Plants, Seston, and Sediment in a Georgia Estuary... 

Table 1. Stable carbon Isotope compositions of the plant, seston, and sediment samples from the Georgia estuary...

A total of 5 plant, 2 seston, and 5 sediment samples from the Georgia estuary for which the stable carbon Isotope composition had previously been determined were analyzed (see Table I). 

Pyrolysis products N, R2, P, S, U, and V, shown In Figure 4, were more specific than those discussed above. Compound V was produced only by sedge, black rush, mixed cypress and hardwood leaves, and In smaller amounts, by swamp soil. The presence of this compound In sediment S-15, but not In other seston or sediment samples, suggests the contribution of specific higher plants to this sediment sample. The occurrence of compound P, In sediment...
