Sources of cobalt include Cobalt sulphate added to the soil, trace mineralised salt and vitamin B12 supplements. We provide geotechnical consulting services for projects with a wide range of needs. Cobalt content of rocks and other soil parent materials. The concentration of cobalt in soil varies widely, generally ranging from about 1 to 40 ppm (1 ppm=1 part of cobalt in a million parts of soil by weight), with an average level of 7 ppm. Cobalt is an element that occurs naturally in the environment in air, water, soil, rocks, plants and animals. ____^-_^__ _ 10 Effect of soil parent material on nutritional disorders in animals 11 Cobalt content of soils associated with cobalt deficiency in animals-- 15 Soil analyses for Co are of little value unless accompanied by parallel analyses for manganese. It can harm the eyes, skin, heart, and lungs. Cobalt deficiency mainly occurs on deep sandy soil, although it can also occur on sandy soils with mottled yellow clay subsoils, loamy sands and gravelly sands. Cobalt is widely dispersed in the environment in low concentrations. Cobalt is an element that occurs naturally in the environment in air, water, soil, rocks, plants and animals. We are a small firm with personnel including geotechnical engineers, geologists, and engineering geologists, each with over 20 years of experience. NGOs say miners in … In Zambia, studies of soil and mango fruit grown near copper and cobalt mines have revealed metals above the safety limit. Workers may be harmed from exposure to cobalt and cobalt-containing products. Monk: Way of the Cobalt Soul. Vitamin B 12 is the only vitamin synthesized solely by a certain small, specialized family of micro-organisms—many of which are abundant in soil. Geotechnical, Geological & Environmental Consulting. Like people, plants need a balanced diet with beneficial microbes, minerals and nutrition. Cobalt, Cadmium, and Lead Sorption to Hydrous Iron Oxide: Residence Time Effect. Cobalt soil concentrations depend on a number of factors including local geology, atmospheric deposition of cobalt-containing dust, land use and associated amendments, mineral particle distribution, soil age, and climactic and transport factors affecting localised concentrations (Wendling et al.
The concentrations of cobalt in soil range from about 1 to 40 ppm and the amount of cobalt in the air is less than 2 ng/m 3. Price Foundation, Spring 2005. Selenium is different from molybdenum and cobalt in that it’s not universally required for plant growth, but it is an extremely important nutrient for livestock and human health, and probably used by many other soil organisms as well.
