Description

Abstract Text:
The proposed project will enhance the vitality, health, sustainability and overall quality of life in the nation and in New Jersey by developing and delivering practical solutions to a myriad of problems that are associated with the toxicity and environmental distribution of mercury. These solutions will be relevant to the safety of the nation's food supply in light of anticipated rising temperatures and their effects on the dynamics and kinetics of mercury cycling in various environments. The toxicity of mercury is greatly dependent on its chemical form by which it is present in the environment; the organic form, methylmercury, is the most toxic due to its bioaccumulation and biomagnifications in food chains. Mercury enters the environment in its inorganic form; processes within the environment convert it to the methylated form that enhances bioavailability. Microbial transformations play a central role in these processes by methylating mercury and by performing other reactions that modulate the environmental production of this toxic substance. The understanding of these processes resulting from the proposed project will serve as the scientific basis for remedial action toward the reduction of mercury contamination, and will provide knowledge to support environmental management decision-making toward minimizing the impact of mercury in contaminated environments.

It is important to recognize, and consider in any interpretation of Federal RePORTER data, that the publication and patent information cannot be associated with any particular year of a research project. The lag between research being conducted and the availability of its results in a publication or patent award varies substantially. For that reason, it's difficult, if not impossible, to associate a publication or patent with any specific year of the project. Likewise, it is not possible to associate a publication or patent with any particular supplement to a research project or a particular subproject of a multi-project grant.
