Mercury in the Moji-Guacu River Basin, S.P-Brazil: the link between marginal lagoons and river contribution, assessed by (210)Pb dating profiles

Article Abstract:

A water chemistry overview is presented on Sao Paulo State's Moji-Guacu River, from its acutely toxic mercury levels observed from 1970 to 1980 to its gradual recovery over the last two decades. Changes in mercury levels are attributed to both natural recovery and a reduction in the output of mercury into the river's ecosystem. A correlation between suspended mercury in the river and bottom sediment of the river's marginal lagoons is discussed.

Socioeconomic consequences of mercury use and pollution

Article Abstract:

A study to examine the life cycle of mercury from a global perspective to identify several approaches to measuring the benefits of reducing mercury exposure was conducted. Findings reveal that almost 90% of anthropogenic emissions come from the combustion of fossil fuels in electric power generation and from the release of Hg in large- and small-scale mining operations affecting the health of humans and wildlife.

A synthesis of progress and uncertainties in attributing the sources of mercury in deposition

Article Abstract:

A panel of experts was convened to address the problem of mercury as a global pollutant. The panel suggested that the uncertainty is strongly dependent upon scale and also agreed that all aspects of predicted climate changes have the potential to affect the mercury cycle in ways that would increase the uncertainty of source attribution.
