Biogeochemical Cycling of Arsenic in Soil–Plant Continuum
The arsenic (As) cycle is the biogeochemical cycle of natural and anthropogenic exchanges of arsenic terms through the atmosphere, lithosphere, pedosphere, hydrosphere, and biosphere. Although arsenic is naturally abundant in the Earth's crust, long-term exposure and high concentrations of arsenic can be detrimental to human health. WebOct 1, 2009 · The biogeochemical cycle. Arsenic is a ubiquitous element of both natural and anthropogenic origin. It is present in the atmosphere, the pedosphere, the hydrosphere and the biosphere. A very exhaustive review on these aspects has been presented by Mandal and Suzuki [6].
