Figure 3

Measured total organic carbon (TOC) and reconstructed TOC. Circles (●) are total TOC measured by the TOC-5000A analyzer. Reconstructed TOC is calculated by compound concentration times number of carbon in compound. Squares (◼) are the quantified organic carbon (sum of carbon in oxalic, malonic, and succinic acids measured by IC and modeled glyoxal and glyoxylic acid). Triangles (▲) (expected TOC) indicate quantified organic carbon minus malonic and succinic acids in 3000 μM experiments.
