Polychlorinated naphthalenes (PCNs) in food and humans
Environment International, 2017 (Uploaded by Plazi for the Bat Literature Project) Polychlorinated naphthalenes (PCNs) are legacy contaminants that are listed by the Stockholm convention, initially for reduction of inadvertent production and ultimately, for elimination. They originate through releases from older electrical equipment, inadvertent contamination in industrial chemicals ...

Sampling and Analysis for Polychlorinated Naphthalenes in the Environment
Journal of AOAC INTERNATIONAL, 1978 Abstract Soil, sediment, biota, 24-hr integrated water, and 2 consecutive 24-hr integrated air samples were collected at several geographic sites, extracted, cleaned up, and analyzed for polychlorinated naphthalenes (PCNs). Analysis by quadrupole gas-liquid chromatography /mass spectrometry / computer (GLC / MS / COMP), using multiple ...

Atmospheric polychlorinated naphthalenes (PCNs) in India and Pakistan [PDF]
Science of The Total Environment, 2014 Polychlorinated naphthalenes (PCNs) are now under review by the Stockholm Convention as candidates for persistent organic pollutants (POPs) due to their persistence, toxicity, bioaccumulation, and long-range atmospheric transport. Data on PCN levels are sparse in South Asia.

Polychlorinated Naphthalenes and Polychlorinated Biphenyls in Benthic Organisms of a Great Lakes Food Chain [PDF]
Archives of Environmental Contamination and Toxicology, 2004 Invasion of zebra mussels, Dreissena polymorpha, and round gobies, Neogobius melanostomus, into the Great Lakes has altered the food web structure and thereby the pathways of toxic contaminants such as polychlorinated biphenyls (PCBs) and polychlorinated naphthalenes (PCNs). In this study, concentrations of PCNs and PCBs were measured in organisms of a
