Naphthalene poisoning (or mothball poisoning) is a form of poisoning that occurs when naphthalene is ingested. Severe poisoning can result in haemolytic anaemia. [citation needed] Naphthalene was introduced in 1841 by Rossbach as an antiseptic to counteract typhoid fever. Although naphthalene was widely used industrially, only nine cases of ...
A naphthalene molecule can be viewed as the fusion of a pair of benzene rings. (In organic chemistry, rings are fused if they share two or more atoms.) As such, naphthalene is classified as a benzenoid polycyclic aromatic hydrocarbon (PAH). [19] The eight carbon atoms that are not shared by the two rings carry one hydrogen atom each.
This was shown when tested on rats via oral ingestion at 1000–5900 mg/kg. [3] NAA has been shown to greatly increase cellulose fiber formation in plants when paired with another phytohormone called gibberellic acid.
The Poison Control Centre of Ain Shams University (PCC-ASU) was established in 1981. It is one of the earliest poisoning treatment facilities to be established in the Middle East. It has its own inpatient department, ICU and Analytical Toxicology unit. [21] It serves between 20 and 25 thousand cases a year.

Sodium naphthalene is an organic salt with the chemical formula Na + [C 10 H 8] −. In the research laboratory, it is used as a reductant in the synthesis of organic, organometallic , and inorganic chemistry.
It is prepared by reduction of 1,5-dinitronaphthalene, which in turn is obtained with the 1,8-isomers by nitration of 1-nitronaphthalene. It can also be prepared by treatment of 1,5-dihydroxynaphthalene with ammonium sulfite. It is a precursor to naphthalene-1,5-diisocyanate, a precursor to specialty polyurethanes. [3]
