| Zusammenfassung |
| Mercury is well known as a dangerous neurotoxin enriched in the environment by human
activities. It disperses over the globe, cycling between different environmental media. The ocean
plays an important role in the global mercury cycle, acting both as a dispersion medium and as an
exposure pathway. In this paper, we review the current knowledge on the major physical and
chemical transformations of mercury in the ocean. This review describes the mechanisms and
provides a compilation of available rate constants for the major processes in seawater, including
oxidation and reduction reactions under light and dark conditions, biotic and abiotic
methylation/demethylation, and adsorption by particles. These data could be useful
for the development of transport models describing processes undergone by mercury in the ocean. |
