Report on how mercury (Hg) was examined in top-predator fish, bed sediment, and water from streams that spanned regional and national gradients of Hg source strength and other factors thought to influence methylmercury bioaccum. Sampled settings include stream basins that were agr¿l, urbanized, undeveloped, and mined. Predator fish were targeted for collection, and composited samples of fish were analyzed for total Hg (THg), as most of the Hg found in fish tissue is MeHg. Samples of bed sediment and stream water were analyzed for THg, MeHg, and characteristics thought to affect Hg methylation, such as loss-on-ignition and acid-volatile sulfide in bed sediment, and pH, dissolved organic carbon, and dissolved sulfate in water.

This ground-breaking volume pushes back conventional dating of the earliest sedentarisation, urbanisation and state formation in the Sahara.

As Maynard grew from a scattering of small hill farms to a booming center of industry and immigration, much of its colorful history was nearly forgotten. With a rollicking collection of his essays, newspaper columnist David A. Mark uncovers the hidden gems of the town's history. Learn why Babe Ruth shopped in Maynard during his Red Sox days and what they fed the animals at the Taylor mink ranch. Find out who is buried--and who is not--in the Maynard family crypt and which rock 'n' roll bands recorded in the studio upstairs from Woolworths on Main Street. Almost lost to time, these remarkable moments in history helped shape Maynard into the vibrant community that it is today.
