TL;DR: The findings suggest that the atmospheric contribution of long-range anthropogenic Hg to High Arctic lakes may have been overestimated by several-fold because of this climate-driven process, and was responsible for no more than 22% of the 20th Century [Hg] increase in the study lakes.

TL;DR: In this article, the authors examined feed-coals used in some Canadian power plants for their mineralogical and elemental composition and determined the mode of occurrence of elements (organic/minerals) in these samples using sequential leaching by H 2 O, NH 4 OAc and HCl.

TL;DR: In this article, the relationship between Hg and organic matter in sediment from eutrophic lakes in central Alberta, Canada has been investigated using the methods conventionally used in petroleum geosciences (rock-Eval® analyses and organic petrology).

TL;DR: In this article, a pilot study of the optical properties of graptolite skeletal materials shows progressive changes of reflectance, bireflectance, refractive index and absorptive index, produced by temperature changes related to depth of burial.

TL;DR: In this paper, the authors compared major ion and isotope geochemistry data for produced fluids or gases from two major coal deposits in Western Canada (Mannville Formation and the Horseshoe Canyon/Belly River Group) with similar data collected for shallow groundwater in south-central Alberta.
