Mercury in Natural Lakes and Unperturbed Terrestrial Ecosystems of Northern Québeceginning of soil formation at the end of the ice age. The recent additional inputs of anthropogenic Hg to these soils mixes with the existing natural Hg pool and represents only a small fraction of the total Hg burden. The cumulative burden of Hg in the humic horizon of podzolic soils averages 2 mgHarbor 发表于 2025-3-28 02:50:12
Bioaccumulation of Mercury and Methylmercury in Invertebrates from Natural Boreal Lakeserences are attributed to the biomagnification of MeHg in the food web with the biomagnification factor between two adjacent trophic levels being about 3. Two principal factors control the contamination of predators at the top of the food chain: (1) the bioavailability of Hg to lower trophic levelsEnrage 发表于 2025-3-28 09:22:38
Mercury in Fish of Natural Lakes of Northern Québeceighboring bodies of water. In the Nottaway-Broadback-Rupert region, where lakes and rivers display a wide range of physical and chemical properties, higher fish Hg concentrations were usually found in bodies of water with high organic content as described by color and concentrations of tannins, asinnovation 发表于 2025-3-28 10:31:26
