Sample "integrity" - an evaluation of sample variability for soils around Rouyn-Noranda, Quebec / R.D. Knight, and P.J. Henderson. : M41-11/46-2017E-PDF
“A detailed soil sample collection grid was established 3 km southwest of the Horne smelter at Rouyn - Noranda, Quebec. The work supports interpretation of a regional geochemical survey of humus and soil within 100 km radius of the smelter and was designed to determine geochemical variability at a site affected by smelter particulate deposition. Soils in the grid are luvisols formed on glacial lake silts and clays and overly pillowed volcanic bedrock. Vegetation comprises small poplars and alders, with a fern ground cover; carbonized stumps and a thin layer of charcoal beneath humus indicate the site has been subject to fire. Litterfall, humus, and B-horizon soil samples were collected at 10, 20, and 30m from the intersection of two perpendicular transects and at a point halfway between the 30m sample locations. Three samples of each were collected at the point of intersection. C-horizon soil was collected at the intersection, the 30m sites, and halfway between the 30m sample locations in preparation for ICP-AES geochemical analyses, litterfall and humus samples were macerated, and all samples sieved to <2mm. The litterfall samples were digested using perchloric acid, and all other samples using aqua-regia. The B- and C-horizon soil samples were analysed in duplicate. A total of 48 analyses were carried out"--Abstract.
