Fig. 4: Projected decreases in MeHg production under elevated CO2 conditions (1000 ppm in 2100) in global lakes.
From: Elevated atmospheric CO2 decreases methylmercury production in freshwater lakes
The predicted DOC concentrations in global lakes with a surface area larger than 0.1 km2 were used (1,427,496 lakes in total, ranging from 0.0002 to 27.0 mg L−1, with an average of 9.24 mg L−1), and the database was obtained from a recent report51. The relationship between DOC and MeHg was adapted from a recent global meta-analysis52. The global map was obtained from Natural Earth dataset (https://www.naturalearthdata.com/downloads/10m-physical-vectors/).
