Protocol for estimating historic atmospheric mercury deposition. Final report
The varied chemical phases and forms of mercury promote its transport and cycling in the environment between water, soil, and air. Many sources--both natural and anthropogenic--contribute to the atmospheric mercury cycle, while several factors modify its deposition and subsequent transformation, distribution, and bioaccumulation. This report introduces a protocol for quantifying spatial and temporal mercury deposition and improving site-to-site comparability of mercury accumulation measurements in natural archives. The report describes the selection of appropriate coring sites to measure mercury accumulation, field methods for lake sediment coring, analysis of sediments, and interpretation of the results from stratigraphic mercury analyses. The new EPRI protocol is expected not only to spur research methods but also to facilitate the global picture of historic mercury deposition needed by policymakers in public organizations, industry, and government.
