Fig. 2: Characteristics of DBC in the leaching experiments.

a Long-term time incubation showing the leaching of DBC (dissolved black carbon), measured as DOC (dissolved organic carbon) concentrations from charcoal in both bacteria-active and bacteria-inhibited river waters during the 1700-day incubation period; b bacterial abundance, and c Δ14C and δ13C values of DOC measured in the river water and bacteria-active and bacteria-inhibited river waters at the end of the experiments. The bar charts are the average values of the duplicate measurements (true value for single point measurement). The black circles are corresponding data points.
