Polychlorinated Naphthalenes in Swedish Background Air

Environmental Science & Technology, 2004
Polychlorinated naphthalenes (PCNs) with four to eight chlorines were studied in air collected at two background stations in Sweden, one southerly and one northerly. Air was sampled with a high-volume sampler, and gas-phase adsorbents and filters were analyzed separately. The sum of TeCNs to HxCNs in the gaseous phase ranged between 1 and 10 pg/m3 with

Polychlorinated naphthalenes in urban air

Atmospheric Environment, 1997
Air samples were collected at an urban site (Chicago, IL) and a semi-urban location (Downsview, Ontario) in February and March 1995 to measure atmospheric concentrations and particle/gas partitioning of polychlorinated naphthalenes (PCN). PCNs were quantified by gas chromatography — negative-ion mass spectrometry (GC-NIMS) against Halowax 1014, a ...

Polychlorinated naphthalenes in polar environments — A review

Science of The Total Environment, 2010
Polychlorinated naphthalenes (PCNs) consist of naphthalene substituted with 1-8 chlorines, yielding 75 possible congeners. They were formerly used in industry, occur at trace levels in commercial PCB mixtures, and have current sources in combustion processes. PCNs are widespread in arctic air with higher levels in the European Arctic.

Degradation of polychlorinated naphthalene by mechanochemical treatment

Chemosphere, 2013
Polychlorinated naphthalene (PCN) is a hazardous compound that is listed as a new persistent organic pollutants candidate by the United Nations Environment Program. The production, import and use of PCNs are prohibited by the Chemical Substances Control Law in Japan. PCN was milled with calcium oxide as an additive to investigate the feasibility of its

Polychlorinated naphthalene exposures and liver function changes

American Journal of Industrial Medicine, 1997
In a clinical assessment for compensation of workers previously exposed to chlorinated naphthalenes, laboratory values demonstrated findings of liver dysfunction. Am. J. Ind. Med. 32:413–416, 1997. © 1997 Wiley-Liss, Inc.

Polychlorinated Naphthalenes (PCNs)

2000
Polychlorinated naphthalenes (PCNs) have been commercially produced and used mainly in electrical devices, but also for impregnation of wood, paper and textiles to attain waterproofness, flame resistance and protection against insects, molds and fungi. Today, the PCNs are widespread in the environment and are to be regarded as an environmental problem.

Polychlorinated Naphthalenes and Coplanar Polychlorinated Biphenyls in Arctic Air

Environmental Science & Technology, 1998
Concentrations of polychlorinated naphthalenes (PCNs) are reported for the first time in arctic air. The data represent combined air samples from the Barents Sea (n = 2), eastern Arctic Ocean (n = 10), Norwegian Sea (n = 2), and two land-based monitoring stations at Alert, Canada (n = 5), and Dunai Island in eastern Siberia, Russia (n = 3). Values for ∑

Correlation of polychlorinated naphthalenes with polychlorinated dibenzofurans formed from waste incineration

Chemosphere, 2001
Isomer composition of polychlorinated naphthalenes (PCNs) was measured for municipal waste incinerator fly ash samples and for emission samples produced from soot and copper-deposit experiments conducted at the United States Environmental Protection Agency (US-EPA). Two types of PCN isomer patterns were identified.

Polychlorinated naphthalenes: an environmental update

Environmental Pollution, 1998
Polychlorinated naphthalenes (PCNs; CNs) form a complex mixture of up to 75 congeners containing from one to eight chlorine atoms per naphthalene molecule. Chloronaphthalenes are widespread global environmental pollutants which accumulate in biota. All chloronaphthalenes are planar compounds and can contribute to the aryl hydrocarbon (Ah) receptor ...

Vapor Pressures of the Polychlorinated Naphthalenes

Journal of Chemical & Engineering Data, 1999
The vapor pressures of the supercooled liquid PL for 17 polychlorinated naphthalene congeners were determined as a function of temperature with a gas chromatographic retention time technique. The method was calibrated with vapor pressure data for polychlorinated biphenyls (PCBs) which had been measured by other techniques.
