Heating limestone produces a chemical substance used in agriculture called pulverized lime, or calcium oxide. Generally, 2 mg of calcium oxide is considered safe for food use; however, concentrations of 25 mg can produce serious side effects including lung inflammation, according to a 2007 report by the Occupational Safety and Health
