Fig. 4

Phytoplankton MeHg volume concentration factors (VCF) for a marine diatom, Thalassiosira pseudonana, for two contrasting DOM types, one marsh site (SI) and one river site (OR). a depicts the VCFs versus the concentration of thiol ligands associated with dissolved organic matter (DOM-RSH). b shows the same VCF information but plotted against the concentration of dissolved organic carbon (DOC) used in the experiments. Error bars represent standard deviation (n = 3, except for site SI with lowest DOM-RSH and DOC concentration where n = 2) and are smaller than visible in some cases. Source data are provided as a Source Data file, including replicate VCF data.
