naphthalene

 [naf´thah-lēn]
a hydrocarbon from coal tar oil, used as a moth repellent, fungicide, and preservative; it is toxic by ingestion, inhalation, and ingestion.

naph·tha·lene

(naf'thă-lēn),
A carcinogenic and toxic hydrocarbon obtained from coal tar; used for many syntheses in industry and in some moth repellents; naphthalene can cause an attack of hemolytic anemia in people with a deficiency of glucose-6-phosphate dehydrogenase.
Synonym(s): naphthalin, tar camphor

naphthalene

Toxicology A crystal formed from 2 benzene rings, used for mothballs and insecticide Toxicity Headache, N&V, hematuria; if severe or prolonged exposure, cataracts, convulsions, hepatocellular necrosis and marked hemolysis, especially in Pts with glucose-6-phosphate dehydrogenase deficiency

For example, studies of human cord blood serum found the dominant congener of dioxins to be octachlorodibenzo-p-dioxin (octaCDD) and that of polychlorinated naphthalenes HxCN [19], which are characterized by the highest values of the octanol-water partition coefficient ([K.sub.OW]) [42,43].

The distribution of total naphthalenes and phenanthrenes in the coal and shale extracts from the Mamu Formation indicates that the total sum of the phenanthrenes and their isomers was greater than that of the naphthalenes in all the samples analyzed (Fig.8).
The questionable assumptions include six main issues: a) high consumer body weight, b) low estimates of seafood consumption, c) failure to include a cancer risk assessment For naphthalene, d failure to adjust for early-life susceptibility to PARs, e) short exposure duration, and f) high cancer risk benchmarks.
If more naphthalenes than previously suspected end up in water rather than air, for example--or if certain kinds of naphthalenes that are more toxic move into the ocean rather than the atmosphere--the harmful effects on marine life could be greater.
Naphthalene and its methylated derivatives represent an important class of environmental pollutants since they are both toxic and slightly water-soluble polyaromatic components found in solid and liquid discharges of petroleum and coal derived operations (Anderson et al., 1974; Winters et al., 1976; Ellis et al., 1991).
