Cobalt (Co) is a metal used in numerous diverse commercial, industrial, and military appliions, many of which are strategic and critical. On a global basis, the leading use of cobalt is in rechargeable battery electrodes. Superalloys, which are used to make parts for gas turbine engines, are another major use for cobalt. Cobalt is also used to make airbags in
Cadmium is a naturally occurring toxic metal with common exposure in industrial workplaces, plant soils, and from smoking. Due to its low permissible exposure in humans, overexposure may occur even in situations where trace quantities of cadmium are found. Cadmium is used extensively in electroplating, although the nature of the operation does not generally lead to overexposure.
Dec 17, 2020 · Cadmium, which is typically inhaled as airborne particulate matter near industrial sites or from cigarette smoke, or which may be ingested from some foods, including leafy and root vegetables, organ meats, and shellfish, also shows heavy soil contamination throughout the Great Plains (Reeves and Vanderpool 1997; USGS 2015) where lifetime ...
During August–November 1992 and August 1993, bed sediment and fish liver were sampled in the South Platte River Basin and analyzed for 45 elements in bed sediment and 19 elements in fish liver. The results for aluminum, arsenic, cadmium, chromium, copper, iron, lead, manganese, selenium, silver, uranium, and zinc are presented here. All 12 trace elements were detected in bed sediment, but ...
Groundwater is a primary source of drinking water in northern Utah County. The groundwater system is recharged mainly from precipitation in the adjacent Wasatch Mountains and infiltration of streamflow. In 2004, groundwater withdrawals were estimated to be roughly 44,500 acrefeet per year. In 2016, groundwater withdrawals were estimated to be ...
The depositfeeding oligochaete Limnodrilus hoffmeisteri possesses metallothioneinlike proteins and metalrich granules for storing and detoxifying cadmium (Cd). In this study we investigated the bioavailability of Cd sequestered within this oligochaete by conducting feeding experiments with 109Cdlabeled oligochaetes and the omnivorous grass shrimp Palaemonetes pugio.
Toxicity of trace metal ions to aquatic organisms, arising through either anthropogenic inputs or acidifiion of surface waters, continues to be both a regulatory and environmental problem. It is generally accepted that the free metal ion is the major toxic species (Florence et a1.,1992) and that inorganic or organic complexation renders the metal ion nonbioavailable (Meador, 1991, Galvez ...
The National WaterQuality Assessment (NAWQA) Project is a leading source of scientific data and knowledge for development of sciencebased policies and management strategies to improve and protect our water resources. In 1991, Congress established the National WaterQuality Assessment (NAWQA) Project to address where, when, why, and how the ...
Cadmium is a natural element in the earth's crust. It is usually found as a mineral combined with other elements such as oxygen (cadmium oxide), chlorine (cadmium chloride), or sulfur (cadmium sulfate, cadmium sulfide).All soils and rocks, including coal and mineral fertilizers, contain some cadmium used in the United States is extracted during the production of other metals like ...
