A study on the effects of mercury in the environment: A focus on atmospheric contributions

Abstract: Mercury is a metal that can transform between different forms in both the atmosphere and in ecosystems. The transformation as well as properties of the different mercury compounds affect when, how and where the effects will emerge. In this literature study, the current state of knowledge about mercury and how it cycles in the environment is reviewed. Different sources for emissions are explored, atmospheric transformation and chemical properties are described and how mercury then enters ecosystems is expounded. The effects that it causes within different ecosystems are then explained as well as the outcome for human health by ingestion, inhalation, and dermal contact. Lastly, methods to remediate the problem are discussed, whilst also emphasizing what the current problems are and what must be done in the future to mitigate or eliminate effects. A lot of things have happened within the field of knowledge over the last couple of years and actions are taken continually.
