Abstract Use of a heterogeneous hydrodechlorination reaction requiring the in situ generation of (Ni 2 B) 2 H 3 by treatment of NiCl 2 with NaBH 4 in isopropanol allows he quantitation of polychlorinated naphthalenes (PCNs) in the presence of polychlorinated biphenyls.

Polychlorinated naphthalenes in sediments from the industrial region of Bitterfeld
Environmental Pollution, 2003Bitterfeld (Germany) was a major site of chemical production in the former German Democratic Republic with chloralkali electrolysis as the basic process. Effluents were dumped via the creek Spittelwasser into the rivers Mulde and Elbe. Despite the fact that the chloralkali industry is known as a possible source of polychlorinated naphthalenes (PCNs ...

Polychlorinated naphthalene concentrations and distribution in feed raw materials
Chemosphere, 2018Concentrations and patterns of 75 PCN congeners in feed raw materials of animal and plant origin were investigated. Six types of feed raw materials of animal origin and three types of feed raw materials of plant origin from China were collected in 2016.

Accumulation of polychlorinated naphthalenes in domestic animal related samples
J. Environ. Monit., 2004Concentrations of polychlorinated naphthalene (PCN) congeners were measured in domestic animal related samples such as feed ingredients, mixed feed and animal fat. Mean concentrations of total PCNs in feed ingredients ranged from 500 to 1500 pg g(-1) lipid wt with a high concentration found in fish meal.

Polychlorinated naphthalenes, polychlorinated biphenyls and ΣDDT residues in British birds of prey
Science of The Total Environment, 1980Abstract Tissue samples (muscle, liver and kidney) from small raptors (kestrels) have been extracted by steam extraction into hexane and the levels of ΣDDT, PCB, PCN and PCT determined by carbon skeleton-gas chromatography. A 3% palladium catalyst, and a 2% RbCl salt column coupled to a mass spectrometer were used for the determination.
