The Laurentian Great Lakes are vast, spatially heterogeneous, and changing. Across these
hydrologically linked basins, some conditions approach biogeochemical extremes for …

We evaluated anthropogenic Pb deposition along a west-east transect from the Adirondack
Mountains, New York, USA (ADIR) region, the Vermont-New Hampshire-Maine, USA (VT …

Geochemical analyses applied to lake sedimentary records can reveal the history of
pollution by metals and the effects of remedial efforts. Lakes provide ideal environments for …

The hydrological conditions of river-connected lakes are complex primarily owing to their
considerable water-level fluctuations (WLFs). Water quality in such lakes varies with …

Water quality data for trace elements in the Great Lakes are relatively scarce, complicating
the assessment of current trace element baselines and their distribution patterns. Here, we …

Sediment cores from 12 locations throughout the Laurentian Great Lakes basin were
analyzed for geochemical indicators of primary production. Sediment analytes included …

We estimated the proportion of hatchery and natural fall spawning chum salmon returning to
the Amur River using chemical markers specific to hatchery-origin fry. We used otolith …

The behaviour and fate of trace elements in surface waters are greatly affected by their
chemical form in solution, but the aqueous speciation of dissolved trace elements in the …

Heavy metals represent substantial environmental and health problems, because of their
persistence and toxicity, affecting air, water, soil via industrial operations, mining, and …
