Thousands of fish are sacrificed each year to determine potential human exposure to mercury (Hg) from fish consumption. In this paper, we use lake whitefish Coregonus clupeaformis and northern pike Esox lucius to demonstrate that accurate and reliabl

A review of Hg concentrations cited in the literature reveals values in the general sequence : grassland herbs < trees and shrubs < aquatic macrophytes < Sphagnum < mosses < lichens < fungi, excluding those samples collected near point sources of env

Three protocols for the determination of inorganic and organic sulfur fractions were tested for their suitability to estimate total indigenous organic sulfur (Sorg) and35Sorg formed from added35SO4 2− in sediments of chemically dilute lakes in the

Gastric emptying time in Scophthalmus maximus, when fed friable artificial pellets based on fishmeal, is composed of two phases: (a) a delay time (td) during which the meal forms a bolus and which shortens with temperature, and (b) an emptying phase

Previous methods of performing aquatic acetylene-reduction assays are described and several problems associated with them are discussed. A refinement of these older techniques is introduced and problems that it overcomes are also discussed. A depth p

Fifteen sediment cores from Lake Mcmphremagog showed pronounced peaks of total phosphorus concentration within the “‘“Pb-defined mixed layer, suggesting that P was migrating upward and accumulating near the mud surface. The mobility of P in the

Lake water samples were observed to transform [ 14 C]ethylene into water-soluble compounds that were undetectable by conventional acetylene reduction assay procedures. Methane oxidizing bacteria, which are known to be common in freshwaters, appeared
