Global emissions of polychlorinated naphthalenes from 1912 to 2050 [PDF]

Nature Communications
Polychlorinated naphthalenes (PCNs) are persistent organic compounds that are regulated by the Stockholm Convention. Here, we estimate historical emissions from PCN production and use (1912-1987) and unintentional emissions from 20 categories (2000-2020).

Distributions of Polychlorinated Naphthalenes in Sediments of the Yangtze River, China [PDF]

Molecules, 2021
The pollution status of polychlorinated naphthalenes (PCNs) in the sediment of the Yangtze River Basin, Asia’s largest river basin, was estimated. The total concentrations of PCNs (mono- to octa-CNs) ranged from 0.103 to 1.631 ng/g.

Removal of polychlorinated naphthalenes by desulfurization and emissions of polychlorinated naphthalenes from sintering plant. [PDF]

Sci Rep, 2016
AbstractThe sintering flue gas samples were collected at the inlets and outlets of the desulfurization systems to evaluate the influence of the systems on PCNs emission concentrations, profiles, and emission factors. The PCNs concentrations at the inlets and outlets were 27888–153672 pg m−3 and 11988–42245 pg m−3,respectively.

Risks for animal and human health related to the presence of polychlorinated naphthalenes (PCNs) in feed and food [PDF]

EFSA Journal
EFSA was asked for a scientific opinion on the risks for animal and human health related to the presence of polychlorinated naphthalenes (PCNs) in feed and food. The assessment focused on hexaCNs due to very limited data on other PCN congeners.

Unveiling the Photodegradation Mechanism of Monochlorinated Naphthalenes under UV-C Irradiation: Affecting Factors Analysis, the Roles of Hydroxyl Radicals, and DFT Calculation [PDF]

Molecules
Polychlorinated naphthalenes (PCNs) are a new type of persistent organic pollutant (POP) characterized by persistence, bioaccumulation, dioxin-like toxicity, and long-range atmospheric transport. Focusing on one type of PCN, monochlorinated naphthalenes (

Determination of Polychlorinated Naphthalenes in Landfill Leachates and its Removal in Wastewater Treatment Processes

Journal of Water and Environment Technology, 2021
Di-through octachlorinated naphthalenes (DiCNs, TrCNs, TeCNs, PeCNs, HxCNs, HpCNs and OcCN) in landfill leachates can be analyzed with the same cleanup procedure as dioxins.

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

Ecotoxicology 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 ...
