What is the problem with graphite

One study found that producing one kg of synthetic Graphite releases 4.9kg of carbon dioxide into the atmosphere and smaller amounts of sulfur oxide, nitrogen oxide, and particulate matter. Although Graphite is not particularly rare, good Graphite crystals are uncommon. Well-known worldwide localities for Graphite are Pargas, Finland; Mount Vesuvius, Italy; Borrowdale, Cumbria, England; and Mont Saint-Sauveur, Quebec, Canada. Pencil lead is made of the mineral graphite. Graphite is not poisonous if you swallow it, but it can be a choking hazard. Puncturing your skin with a pencil is not poisonous but can lead to infection. Excessive exposure to Graphite presents serious dangers to the respiratory system. Well-documented health effects include lung fibrosis and pneumoconiosis, an occupational lung disease. The cardiovascular system can be affected, as well, with workers suffering from possible decreased pulmonary function. They also discovered that the grain boundary regions in the individual carbon sheets are magnetically coupled and form 2D networks. This coupling explains why Graphite is a permanent magnet. The "lead" in pencil isn't made from lead. It is made from a form of carbon called Graphite. The Graphite is mixed with clay and formed into long thin pencil lead. False. Lead pencils contain Graphite (a form of carbon), not lead. In fact, contrary to what many people believe, lead pencils never were made with lead. (—A team of researchers working at Rice University in the U.S. has demonstrated that graphene is better able to withstand the impact of a bullet than either steel or Kevlar.
