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.

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 ...

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.

Pathways to Aromatics in the Catalytic Pyrolysis of a Polyvinylchloride Model Compound Revealed by Operando Photoelectron Photoion Coincidence Spectroscopy. [PDF]

ChemSusChem
How are aromatics formed during catalytic PVC pyrolysis? By utilizing photoelectron photoion coincidence spectroscopy, the cross‐linking reaction mechanism is unveiled to proceed via butadiene dimerization and trimerization, yielding 5‐ or 6‐membered ring species, which are the precursors for benzene, toluene, and xylenes.

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 ...

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 ...

Bridging the Energy Benefit and POPs Emission Risk from Waste Incineration

The Innovation, 2021
Summary: Incineration has been the globally controversial and concerned method of solid waste disposal. Energy recovery and volume reduction are the benefits from waste incineration, but risk due to release of persistent organic pollutants is the major ...
