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.

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).

Polychlorinated naphthalenes in human milk: Health risk assessment to nursing infants and source analysis

Environment International, 2020
Polychlorinated naphthalenes are teratogenic environmental contaminants. Mother milk is the most important food for nursing infants. The World Health Organization actively promotes breastfeeding for its immunological, psychological, and economic ...

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.

Climate-Action Driven Emission Changes of Unintentional Persistent Organic Pollutants From Global Copper Industry. [PDF]

Glob Chall
Climate action profoundly reshapes global copper production by increasing output and altering the production technology mix. These changes also raise emissions of unintentional persistent organic pollutants (UPOPs) from the copper industry, revealing a hidden pollution trade‐off that should be addressed alongside decarbonization.

Climate Action Impacts on Steelmaking Emissions of Persistent Organic Pollutants Highlight a Gap Between the Paris Agreement and the Stockholm Convention. [PDF]

Adv Sci (Weinh)
Emissions of unintentionally produced persistent organic pollutants (UPOPs) and global warming are two major environmental challenges. But their governance has largely evolved in parallel, leaving the toxicity implications of climate‐driven industrial transitions poorly understood.

Characterization of 9 Gas Chromatography Columns by Linear and Lee Retention Indices for Polychlorinated Biphenyls and Polychlorinated Naphthalenes

Separations, 2020
Polychlorinated biphenyls (PCBs) and naphthalenes (PCNs) are ubiquitous environmental contaminants with varying degrees of toxicity. There are hundreds of possible congeners with similar chemical characteristics, which make these compounds difficult to ...

A review on occurrence and analytical procedures for the evaluation of polychlorinated naphthalenes in human and environmental matrices

Environmental Pollutants and Bioavailability, 2020
Polychlorinated naphthalenes (PCNs) are organochlorine compounds comprising  the naphthalene ring system, in which one to eight hydrogen atoms have been substituted with chlorine atoms, yielding 75 chlorinated 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 (

Risk prioritisation of (emerging) contaminants in aquaculture production. [PDF]

EFSA J
Abstract The European Union (EU) food safety legislative framework is designed to guarantee the safety of the entire food production chain through a comprehensive ‘from farm to fork’ approach. Chemical safety of the food production chain, encompassing contaminants, veterinary drugs and pesticide residues, food/feed additives, is further regulated by a ...
