Metal concentrations and other variables were measured in the bottom sediments of 390 British Columbia lakes considered to be relatively unaffected by human pollution. The variables tested for were Al, As, B, Ba, Be, C (organic and inorganic), Ca, Cd, Co, Cr, Cu, Fe, Hg, Mg, Mn, Mo, N (Kjeldahl), Ni, P, Pb, S, Se, Sn, Sr, Ti, V, Zn, and volatiles. Mean concentrations were calculated by tectonic region, tectonic sub-region, and individual lake. Variables were also compared in regression analyses as a function of lake water and sediment pH, organic C, S, Fe, and Mn sediment concentration, lake surface area, mean depth, volume, and altitude, sample depth, watershed size, and runoff. Northern sub-regions showed higher values for mean concentrations for more variables (22) than southern sub-regions (5) or central sub-regions (2). Aluminum, Ca, Mg, and Pb showed evidence of significant relationships with 8 of the 13 independent variables tested, while Be showed no evidence of a relationship with any of the independ
