Role of oceans as biogenic sources of selenium
The pathways leading to the volatilisation and atmospheric transfer of selenium from oceanic environments are poorly understood. They may however affect the global distribution of selenium and its impact on marine and terrestrial ecosystems. In this paper we describe the results of experiments which...
