Barium (Ba) is obtained chiefly from the mineral barite. Barium is a soft, silvery, reactive metal. Because barium is so dense it is commonly used in some alloys, for example in spark plugs and ball bearings. As of 2013, China, India and Morocco were the world's largest producers of barium. In the U.S, barite is mined primarily in Nevada and ...

Barium is also toxic to plants, but its uptake is generally low because of its low solubility (Salminen et al., 2005).No correlation has been found between vegetable and paired soil concentrations for Ba due to the strong effect that soil pH, organic matter content and other soil properties have on Ba solubility and bioavailability (McBride et al., 2014).
