- Statement
- DOC concentrations were determined as non-purgeable organic carbon (NPOC) following Marques et al. (2017; doi: 10.3389/feart.2017.00011). Briefly, samples were vacuum-filtered (GF/F filters Whatmann, nominal pore size 0.7 µm), two 150 ml aliquots were subsampled from each sample for DOC analysis (automated total organic carbon (TOC) analysis on a Shimadzu TOC 5000 analyzer). For DBC, 500 ml of each filtered water sample was acidified to pH2 with HCl (32%, analytical grade). Solid phase extraction (SPE) was then performed on the acidified samples using Bond Elut PPL SPE cartridges (1 g; Agilent Technologies). DBC concentrations were determined following the benzene poly-carboxylic acid (BPCAs) method, following Marques et al. (2017, doi: 10.3389/feart.2017.00011); BPCAs are quantified by UPLC (Waters Acquity UPLC) with a photodiode array light-absorbance detector.
