Survey Description

In October 1997, samples were collected at 21 sites within a 50 km radius of the Trail lead-zinc smelter, British Columbia.  A-, B- and C-horizon soils developed on till were sampled.  Sites are located along two transects extending north and northeast from the point source.  Sand or sandy diamicton (till) was the main mineral soil sampled along the northern transect; diamicton (till) makes up a high proportion of the samples from the northeast transect, although sand was collected at some sites in lower elevations.  Because humus was generally poorly developed in the area, the organic-rich upper part of the soil horizon (A-horizon) was also collected.  A description of the work can be found in Geological Survey of Canada Current Research 1999-D.

Data Description:

Paper report, no data lists, but ranges of element values in tables.  The paper compares results for Trail with those from smelters at Rouyn-Noranda, Quebec and Flin Flon Manitoba.

Quantities Analysed:

<0.425 mm fraction of humus by ICP-AES after aqua regia digestion; <0.063 mm and <0.002 mm fraction of mineral soils by ICP-AES after aqua regia digestion.

Geochem Maps Available:

Profiles showing metal concentrations along the transects.
