PubTalk 9/200 — Toxic Mercury in Aquatic Ecosystems
Why Quality Trumps Quantity
by Mark Marvin-DiPasquale, Microbial Ecologist
- Different mercury sources generate different forms of mercury with different environmental consequences
- Learn how mercury is transported and transformed in air and water, and how it ultimately accumulates as toxic methylmercury in wildlife and humans
- How do mercury-methylating bacteria react with "new" mercury from atmospheric deposition and with "old" mercury from remobilized sediments?
- Why are fish in Florida's Everglades as contaminated with mercury as those in San Francisco Bay, even though total mercury inputs are much higher in the Bay?
- How do differences in landscape and vegetation type affect mercury cycling and bioaccumulation pathways?
