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 ...

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.

Formation of polychlorinated naphthalenes from chlorophenols

Proceedings of the Combustion Institute, 2005
Abstract To test the hypothesis that polychlorinated naphthalenes (PCNs) can be formed from chlorinated phenols via cyclopentadienyl radicals in post-combustion gas containing 8% oxygen, the slow combustion of three chlorophenols (CPs) at 600 °C was studied in a laminar flow reactor. Contrary to the a priori hypothesis, different distributions of PCN

Acute toxicity of polychlorinated naphthalenes and their effect on cytochrome P450

Human and Experimental Toxicology, 2006
Polychlorinated naphthalenes (PCNs) are able to induce cytochrome P-450-dependent microsomal monooxygenase activities in vivo and in vitro. The aim of this study was to investigate the toxicity of a PCN mixture, and its effect on the levels of cytochrome P-450 in rats.

Photodegradation of polychlorinated naphthalene in mixtures

Environmental Pollution, 2020
Solutions of technical polychlorinated naphthalene (PCN) Halowax formulations (Halowax 1014 and Halowax 1051) diluted with Milli-Q water and sealed in the Pyrex glass tubes and quartz tubes were subjected to artificial solar and natural solar irradiation under different time intervals and field conditions.

Atmospheric Polychlorinated Naphthalenes in Ghana

Environmental Science & Technology, 2012
A nationwide monitoring of atmospheric POPs (persistent organic pollutants) was conducted in Ghana between May and July 2010, applying polyurethane foam (PUF) disk passive air samplers (PAS). Reported here are preliminary findings on PCNs, an industrial organic contaminant currently under review for possible listing under the global chemical treaty ...

Discrimination between polychlorinated naphthalenes and polychlorinated biphenyls

Journal of Chromatography A, 1978
Abstract Prcedures for the discrimination between polychlorinated biphenyls (PCBs) and polychlorinated naphthalenes (PCNs) taken from the literature are discussed. It is demonstrated that the analysis of mixtures of PCBs and PCNs can conveniently be accomplished by both high-performance liquid and gas chromatography, after their conversion into the ...
