Survey Description
During the summer of 1987, a helicopter supported lake sediment sampling survey was conducted by the SIAL company, in the Fermont area, Quebec. The sampling was done using a probe. Approximately 6,600 sites were collected at an average density of 1 sample per 13 km2. The area covers 86,965 km2. Samples were analyzed for:
| Element | Dissolution | Technique |
| Ag, Al, B, Ba, Ca, Cd, Ce, Co, Cr, Cu, Eu, Fe, K, La, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Sc, Sm, Sr, Th, Ti, V, Zn |
HNO3/HCl |
inductively coupled plasma emission (ICP-ES) |
| As, Au, W, U, Sb, Br, Cs, Se, Tm | neutron activation (INAA) | |
| perte au feu | ||
| pH | ion selective electrode (ISE) | |
| Hg | atomic absorption (AAS) |
Some data are published in Open File MB 88-38, Department of Energy and Resources, 1988. All data are published in Open File MB 89-33, Department of Energy and Resources, 1989.
A subset of the samples was reanalysed by ICP-MS in 2007 (n=306) and in 2010 (n=1471) and the work is summarized in Ministère des Ressources naturelles et de la Faune reports PRO 2008-08 and PRO 2011-02 respectively.
