摘要:
Using a coulometric titration technique, carbon content was determined in biotic and abiotic samples collected in Pool 19 of the upper Mississippi River. With the exception of waterfowl tissue, biotic samples contained substantially less organic carbon than the 50% assumed a priori. Inorganic carbon in soft tissues of biota was not quantitatively significant. Organic carbon content in substratum samples varied among habitats from which the samples were collected.
