Short summary
We studied how environmental factors influence the release of mercury from seawater to the atmosphere. We applied a novel approach in which prior knowledge about cause-and-effect is captured as graphical models and then used to estimate effect sizes. Results showed that sunlight affects mercury both directly and indirectly, with about 32 % of the effect explained by temperature increase. Thus, causal models can improve our understanding of pollution processes and the effect policies.
