Its formula is C10H8 and it is a compound, not an element. When naphthalene is metabolized in the liver, oxidative stress induces massive hemolysis, resulting in hemolytic anemia, methemoglobinemia, hemoglobinuria, and jaundice.It is generally known that glucose-6-phosphate dehydrogenase (G6PD) deficiency increases the risk for hemolysis due to Approximately, 0.610 g of finely divided naphthalene was added in small portions to the solution while stirring after each addition, and cooling to keep the temperature around 45-50C. These solid pellets or spheres directly sublime from solid to gas, and proper use includes keeping it in tightly-lidded containers and out of reach from children and pets. The Environmental Protection Agency regulates them in the United States. The vapor given off when Naphthalene is heated is FLAMMABLE and a DANGEROUS FIRE HAZARD.
