Mercury concentrations in fish across the United States.
Objective is to determine if mercury concentrations differ by watershed land use. Can concentrations be related to water and sediment characteristics of the streams?
There are three detection limits, at 0.03, 0.05, and 0.10 ug/g wet weight. Used in Chapters 10, 11 and 12 of the Helsel (2011) book.
