Mercury and Organic Matter Concentrations in Lake and Stream Sediments in relation to One Another and to Atmospheric Mercury Deposition and Climate Variations across Canada

Figure 6

Scatterplots of actual versus least-squares best-fitted (i) lake (a) and (ii) stream (c) sediment log₁₀THg [log₁₀ (ng g⁻¹)], (iii) GRAHM2005 atmospheric Hg deposition ((b); model), and (iv) stream and lake sediment log₁₀LOI ((d); dashed line separates the lake from the stream dots); all symbolized by provinces/territories (Table 5).

(a) Best-fitted log₁₀THg [log₁₀ (ng g⁻¹)] (5)

(b) Best-fitted GRAHM2005 atm.Hg_dep (µg m⁻² a⁻¹) (3)

(c) Best-fitted log₁₀THg [log₁₀ (ng g⁻¹)] (6)
