The toxicological profile of polychlorinated naphthalenes (PCNs) [PDF]

open access: yesScience of The Total Environment, 2022
The legacy of polychlorinated naphthalenes (PCNs) manufactured during the last century continues to persist in the environment, food and humans. Metrological advances have improved characterisation of these occurrences, enabling studies on the effects of exposure to focus on congener groups and individual PCNs. Liver and adipose tissue show the highest

Polychlorinated naphthalenes (PCNs) in food and humans

open access: yesEnvironment 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 ...

The transfer of environmental contaminants (Brominated and Chlorinated dioxins and biphenyls, PBDEs, HBCDDs, PCNs and PFAS) from recycled materials used for bedding to the eggs and tissues of chickens.

open access: yesScience of the Total Environment, 2023
Some types of poultry bedding made from recycled materials have been reported to contain environmental contaminants such as polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs, dioxins), polychlorinated biphenyls (PCBs) brominated flame ...

Polychlorinated naphthalenes (PCNs):Congener specific analysis, occurrence in food, and dietary exposure in the UK

open access: yes, 2010
Information on the occurrence of toxicologically significant polychlorinated naphthalenes (PCNs) in food, or on human exposure, is sparse. In this work, PCN congeners (PCNs 52, 53, 66/67, 68, 69, 71/72, 73, 74, and 75) were selected for analysis, based ...

Contamination and sources of polychlorinated naphthalenes in the surface sediments of Chaobai River, China

open access: yesEcotoxicology and Environmental Safety, 2022
In aquatic systems, sediment is both a sink for persistent organic pollutants (POPs) and a potential source of POPs release. Consequently, it is important to understand the pollution characteristics and sources of polychlorinated naphthalenes (PCNs) as ...

PCN: Point Completion Network [PDF]

open access: yes2018 International Conference on 3D Vision (3DV), 2018
Shape completion, the problem of estimating the complete geometry of objects from partial observations, lies at the core of many vision and robotics applications. In this work, we propose Point Completion Network (PCN), a novel learning-based approach for shape completion.
