| Gefahrenübersicht | Naphthalene is used in the production of phthalic anhydrideit is also used in mothballs. Acute (short- term) exposure of humans to naphthalene by inhalation, ingestion, and dermal contact is associated with hemolytic anemia, damage to the liver, and neurological damage. Cataracts have also been reported in workers acutely exposed to naphthalene by inhalation and ingestion. Chronic (long-term) exposure of workers and rodents to naphthalene has been reported to cause cataracts and damage to the retina. Hemolytic anemia has been reported in infants born to mothers who "sniffed" and ingested naphthalene (as mothballs) during pregnancy. Available data are inadequate to establish a causal relationship between exposure to naphthalene and cancer in humans. EPA has classified naphthalene as a Group C, possible human carcinogen.Ingestion of high doses of naphthalene can induce methemoglobinemia and precipitate subacute hemolysis. The lethal dose orally for an adult is 5-15 grams. Workers deficient in glucose-6-phosphate dehydrogenase are more susceptible to hemolysis. A 1956 study found cataracts in 8 of 21 workers who melted naphthalene in open vats. After new procedures to reduce exposures, no further cataracts were reported. [ACGIH] Chronic sniffing of naphthalene containing mothballs can cause liver necrosis. [HSDB] Naphthalene is not hepatotoxic in experimental animal studies or in human exposures.

| Lagerbedingungen | Without inert-gas blanketing and at the temperature normally used for the storage of molten naphthalene, i.e., 90 °C, the vapors above the liquid are within the flammability limits. Thus, storage tanks containing molten naphthalene have a combustible mixture in the vapor space and care must be taken to eliminate all sources of ignition around such systems. Naphthalene dust can form explosive mixtures with air which necessitates the design and operation of solid handling systems.Store in a cool, dry, well-ventilated location. Separate from oxidizing materials. May be stored under nitrogen gas.Always store in a cool, dry, dark place.PRECAUTIONS FOR "CARCINOGENS": Storage site should be as close as practical to lab in which carcinogens are to be used, so that only small quantities required for ... expt need to be carried.

| Wechselwirkungen | Ip injection of channel catfish (Ictalurus punctatus) with 100 ug benzo(a)pyrene, Aroclor 1254, or naphthalene, singly and in combinations, affected the levels of the brain neurotransmitters norepinephrine, dopamine, and 5 hydroxytryptamine, but the effect showed no discernible pattern. The effects of combinations of the chemicals did not appear to be predictable from the effects of individual chemicals. In several instances, the change in the level of neurotransmitter in fish receiving a combination of chemicals was greater than in fish receiving either chemical alone....50 cases of severe chronic effects from repeated ingestion of a naphthalene- isopropyl alcohol "cocktail" have been recorded. The symptoms resembled those of ethanol intoxication and consisted of tremors, restlessness, extreme apprehension, and hallucination. The effects subsided in a few days.When... naphthalene... was applied dermally in combination with benzo(a)pyrene (BaP), there was an inhibitory effect on the induction of skin tumors in female mice.The administration of /mixed function oxidase/ (MFO) inhibitors (SKF-525A, metyrapone) and antioxidants (caffeic acid and vitamin E) decreased ocular toxicity in mice.For more Interactions (Complete) data for NAPHTHALENE (8 total), please visit the HSDB record page. |

| Gesundheitliche Auswirkungen | Inhalation of naphthalene vapor has been associated with headaches, nausea, vomiting and dizziness. Hemolysis, the abnormal breakdown of red blood cells, may occur following ingestion or sufficient dermal exposure to either naphthalene or to naphthalene-treated fabric. In humans, cataracts and other ocular injury have been reported following acute and chronic occupational exposure to naphthalene. Additional signs of toxicity in children include convulsions and coma. Infants may develop encephalopathy and kernicterus, a form of brain damage, due to the presence of increased levels of methemoglobin, hemoglobin, and bilirubin in their plasma. Naphthalene appears to be mildly carcinogenic. Rats exposed to naphthalene vapors at 10, 30, or 60 ppm for 6 hours a day, five days a week for two years developed respiratory epithelial adenomas and olfactory epithelial neuroblastomas. |

| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), Koc values of 112 to 9,333(2-4) indicate that naphthalene is expected to have high to no mobility in soil(SRC). Volatilization of naphthalene from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 4.4X10-4 atm-cu m/mole(5). The estimated volatilization half-life for naphthalene from soil is 1.1 days, and 14 days when incorporated at a depth of 1 cm and 10 cm, respectively(6). Naphthalene is not expected to volatilize from dry soil surfaces based upon a vapor pressure of 0.085 mm Hg at 25 °C(7). In soils previously exposed to naphthalene or other PAHs, half-lives of 2-18 days have been reported(8).AQUATIC FATE: Based on a classification scheme(1), Koc values of 112 to 9333(2-4) indicate that naphthalene is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(5) based upon a Henry's Law constant of 4.4X10-4 atm-cu m/mole(6). Using this Henry's Law constant and an estimation method(5), volatilization half-lives for a model river and model lake are 6 hours and 5 days, respectively(SRC). Naphthalene is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(5). According to a classification scheme(7), BCFs of 36.5-168 in carp(8) and 692-714 in minnows(9), suggest the potential for bioconcentration in aquatic organisms is moderate to high(SRC). Naphthalene has been shown to biodegrade in water with half-lives ranging from about 0.8 to 43 days(10-11).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), naphthalene, which has a vapor pressure of 0.085 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase naphthalene is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 14-16 hours(3), calculated from its rate constants of 2.73X10-11 to 2.16X10-11 cu cm/molecule-sec at 25 °C(3-5). Vapor-phase naphthalene is also degraded in the atmosphere by reaction with nitrate radicals(SRC)the nighttime half-life for this reaction in air is estimated to be 60 hours(SRC), calculated from its rate constant of 6.4X10-15 cu cm/molecule-sec at 25 °C(6). Naphthalene absorbs light in the environmental UV spectrum and, therefore, direct photolysis may occur(7). |

| Toxizitätsübersicht | PAH's such as naphthalene are transported throughout the body after binding blood proteins such as albumin. Binding to the aryl hydrocarbon receptor or glycine N-methyltransferase induces the expression of cytochrome P450 enzymes (especially CYP1A1, CYP1A2, and CYP1B1). These cytochrome enzymes metabolize PAH's into various toxic intermediates (epoxide intermediates, dihydrodiols, phenols, quinones, and their various combinations). The reactive metabolites of PAHs covalently bind to DNA and other cellular macromolecules, initiating mutagenesis and carcinogenesis. (10, 12, 2, 3). In humans, the metabolite alpha-naphthol has been linked to the development of hemolytic anemia in some cases following ingestion or extensive dermal or inhalation exposure. Susceptibility appears to be exacerbated by a deficiency in the glucose 6-phosphate dehydrogenase enzyme, or G-6-PD. Over 400 million people have an inherited condition called glucose-6-phosphate dehydrogenase deficiency. Exposure to naphthalene is more harmful for these people and may cause hemolytic anemia at lower doses. Some naphthalene metabolites deplete glutathione stores in affected tissues such as the lungs, leading to toxicity. The metabolites responsible for glutathione depletion have been identified as naphthalene oxide or 1,2-naphthoquinone and 1,4-naphthoquinone. |

| FIFRA-Anforderungen | The Agency has completed its assessment of the human health and ecological risks associated with the use of pesticide products containing naphthalene. The Agency has determined that naphthalene-containing products are eligible for reregistration provided that label amendments are made as outlined in Chapter V. ... Based on its evaluation of naphthalene, the Agency has determined that products containing naphthalene, unless labeled and used as specified in this document, would present risks inconsistent with FIFRA. Accordingly, should a registrant fail to implement any of the risk mitigation measures identified in this document, the Agency will take regulatory action to address the risk concerns from the use of naphthalene. If all changes outlined in this document are incorporated into the product labels, then all current risks for naphthalene will be adequately mitigated for the purposes of this determination under FIFRA.As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their continued use. Under this pesticide reregistration program, EPA examines newer health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether the use of the pesticide does not pose unreasonable risk in accordance to newer safety standards, such as those described in the Food Quality Protection Act of 1996. Naphthalene is found on List A, which contains most pesticides that are used on foods and, hence, have a high potential for human exposure. List A consists of the 194 chemical cases (or 350 individual active ingredients) for which EPA issued registration standards prior to FIFRA '88. Case No: 0022Pesticide type: insecticideRegistration Standard Date: 09/01/81Case Status: OPP is reviewing data from the pesticide's producers regarding its human health and/or environmental effects, or OPP is determining the pesticide's eligibility for reregistration and developing the RED (Reregistration Eligibility Decision) document.Active ingredient (AI): naphthaleneData Call-in (DCI) Date(s): 05/06/91, 10/13/95AI Status: The producers of the pesticide have made commitments to conduct the studies and pay the fees required for reregistration, and are meeting those commitments in a timely manner. |
