	RAIS: Napthalene (91-20-3)
		Naphthalene is used directly as a moth repellant, insecticide, anthelmintic, and intestinal antiseptic (U.S. Most of the naphthalene entering the environment is released directly to the air from sources such as burning of fossil fuels and use of naphthalene-containing mothballs.
		Following oral exposure, naphthalene was detected in the fat, liver, lungs, and heart of swine; in the liver and milk of dairy cows; and in the liver, kidneys, lungs, fat, and yolk of laying pullets (Eisele, 1985).
		Although glutathione conjugation of naphthalene is a major metabolic pathway for rats as evidenced by urinary excretion of thioethers (Summer et al., 1979), metabolism of naphthalene to thioethers was not demonstrated in rhesus monkeys or chimpanzees (Rozman et al., 1982; Summer et al., 1979).

		Numerous hydrides are known; heated with red phosphorus and hydriodic acid the hydrocarbon yields mixtures of hydrides of composition C10H10 to C10H20.
		A 2.6 naphthoquinone results on oxidizing 2.6 dihydroxynaphthalene with lead Or Hydroxynaphthalenes, C 1 oH 7 OH, the naphthalene homologues of the phenols.
		The hydroxyl group is more reactive than in the phenols, the naphthols being converted into naphthylamines by the action of ammonia, and forming ethers and esters much more readily.

	Science Fair Projects - Naphthalene
		Naphthalene (also known as naphthalin, naphthaline, tar camphor, white tar, albocarbon, or naphthene) is a crystalline white solid hydrocarbon with a typical mothball odor.
		Accordingly, naphthalene is classified as a benzenoid polycyclic aromatic hydrocarbon (PAH).
		Exposure to large amounts of naphthalene may also cause nausea, vomiting, diarrhea, blood in the urine, and a yellow color of the skin.

		Naphthalene, a white, crystalline powder, is used as a moth repellent and in the manufacture of phthalic and anthranilic acids, naphthylamines, and synthetic resins.
		In the nose, naphthalene exposure was associated with an increase in the incidence and severity of chronic inflammation, metaplasia of the olfactory epithelium, and hyperplasia of respiratory epithelium.
		In both male and female mice, naphthalene caused increased incidences and severity of chronic inflammation, metaplasia of the olfactory epithelium, and hyperplasia of the respiratory epithelium in the nose and chronic inflammation in the lungs.

	Naphthalene (CASRN 91-20-3) \| IRIS \| US EPA
		As discussed earlier, deriving the naphthalene RfD based on 1-methylnaphthalene data was judged to be too uncertain because of metabolic differences between naphthalene and methylnaphthalenes and the absence of lung injury in rats and mice orally exposed to naphthalene for subchronic periods.
		This hypothesis is supported by data on naphthalene metabolism indicating that toxic effects on the respiratory tract are due to a naphthalene metabolite that may be formed either in the liver or in the respiratory tract.
		Naphthalene was not mutagenic in Salmonella typhimurium assays in the presence or absence of liver metabolic preparations (Bos et al., 1988; Connor et al., 1985; Florin et al., 1980; Godek et al., 1985; McCann et al., 1975; Nakamura et al., 1987; Narbonne et al., 1987; NTP, 1992a; Sakai et al., 1985).

	Naphthalene Summary
		Naphthalene (also known as naphthalin, naphthaline, tar camphor, white tar, albocarbon, or naphthene) is a crystalline, aromatic, white, solid hydrocarbon, best known as the primary ingredient of mothballs.
		Naphthalene's most familiar use is as a household fumigant, for example in mothballs.
		Naphthalenes substituted with combinations of strongly electron-donating functional groups, such as alcohols and amines, and strongly electron-withdrawing groups, especially sulfonic acids, are intermediates in the preparation of many synthetic dyes.

	Eco-USA: Naphthalene
		Naphthalene enters the environment from industrial uses, from its use as a moth repellent, from the burning of wood or tobacco, and from accidental spills.
		Naphthalene is generally not found in water, but when it is present, the levels are usually lower than 0.01 ppm.
		Naphthalene can be smelled in air at a concentration of about 0.08 ppm and can be tasted in water at a concentration of about 0.02 ppm.

	Environment Writer Chemical Backgrounder Naphthalene
		Naphthalene (C.A.S. 91-20-3) is a white solid with a strong smell; is also called mothballs, moth flakes, white tar, and tar camphor.
		Naphthalene is a natural component of fossil fuels such as petroleum and coal; it is also formed when natural products such as wood or tobacco are burned.
		Naphthalene is more dangerous to African-Americans and people of Mediterranean descent, because these populations have a higher incidence of problems with the enzyme which helps produce red blood cells.

		The presence of low concentrations of naphthalene in carton nests of C. formosanus may be the result of its release as a byproduct of the process of lignin degradation.
		The presence of naphthalene in decayed redwood sawdust was further investigated due to reports of its presence in carton nests of C. formosanus and to reports that naphthalene induces trail-following behavior in C. formosanus.

	Naphthalene based snake repellant - Patent 5104900
		Naphthalene is a volatile hydrocarbon having the formula C.sub.10 H.sub.8 and the following structure: ##STR1## It is obtained from the middle oil fraction of coal tar oils that boil between 170.degree.
		The resulting naphthalene crystals vaporize in air to produce a strong odor that is believed to be offensive to snakes so that when it is detected, the snakes turn away from that location.
		Naphthalene is the active ingredient and is produced in the form of flakes refined to a purity of 99%.
