This slide presentation summarizes trophic-transfer modeling of mercury in the South River. It presents 2007 sampling locations and tests models for total Hg, methylmercury, and fraction methyl-Hg. Methylmercury models were predictive (biomagnification ≈4.6-fold per trophic level); total-Hg models need improved periphyton definition. The slides note increasing methyl-Hg downstream and trophic dilution of inorganic Hg.

Review Notes :
This is a slide deck (presentation) describing trophic transfer models; the slides show 2007 sampling sites and model results. No explicit publication or presentation date is visible in the PDF pages provided, though the original filename suggests April 8, 2008 — that date was not used because the PDF itself is authoritative.
