Among potentially toxic trace elements introduced in the environment by both natural and anthropogenic sources, mercury is of major concern due to its toxicity and relatively high bioavailability of its most toxic chemical form, methylmercury. Mercury contamination may seriously affect different environmental matrices including soils, sediment, plants, waters and air. Its mobility among different environmental compartments is regulated by biogeochemical processes that are of key importance to evaluate its behavior and final fate. The control and minimization of the mercury emissions from all the relevant sources and the knowledge reinforcement of its dispersion mechanisms in the environment are thus of paramount importance in the context of current global changes of our planet.
In this framework, this session welcomes interdisciplinary studies focused on mercury and dealing with:
i) sources, behavior and fate in aquatic, terrestrial and atmospheric environments
ii) biogeochemical behavior/cycle of Hg in natural and mine contaminated sites
iii) innovative sampling and analytical protocols and research and monitoring programs to identify and quantify the contribution operated by different mercury sources
iv) risk assessment and remediation solutions for the correct management of contaminated sites.
