Temporal trends, sources, and relationships between sediment characteristics and polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in sediment cores from the major Seine estuary tributary, France

Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.

Polycyclic Aromatic Hydrocarbons and Potentially Toxic Elements in Soils of the Vicinity of the Bulgarian Antarctic Station “St. Kliment Ohridski” (Antarctic Peninsula)

“…Since the climatic conditions of Livingstone Island are similar to those of the northern taiga, it should be recognized that the occurrence of these PAHs is linked more to natural than anthropogenic sources. Most sources use these two ratios to identify PAHs in locations with high anthropogenic load (Yan et al, 2006;Jiang et al, 2019;Gardes et al, 2020). Since there is no practice of burning wood fuel, coal and grass under Antarctic conditions, these two ratios have shown controversial results.…”

Polychlorinated Naphthalenes in Foods from the French Market: Occurrence, Dietary Exposure, and Evaluation of Relative Contributions to Dioxin-like Contaminants

“…These differences were all significant except for ∑PCB concentrations (Kruskal–Wallis test, see Table SI6); comparing the same species furthermore led to observe ∼70 and ∼15 times higher POP concentrations, respectively, in Atlantic versus Pacific mussels and in Northern prawns versus white shrimps from the Western Indian Ocean. Despite the low number of samples which does not allow statistically significant conclusions to be drawn, it should be mentioned that the fishing area cited above is close to the Seine Estuary, known to be contaminated by several classes of chemicals due to urban and industrial activities. − Such a hypothesis has already been formulated in previous work to explain the higher concentrations of PCNs in fish and seafood acquired in 2005 in Le Havre, a city also located near this Estuary …”

Organohalogenated Substances and Polycyclic Aromatic Hydrocarbons in Fish from Mediterranean Sea and North Italian Lakes: Related Risk for the Italian Consumers

“…PAHs are derived from both anthropogenic activities (incinerators, industrial processes, motor vehicles, combustion of wood and fossil fuels, oil spills, etc.) and natural sources (incomplete combustion of organic matter and pyrolysis) [ 15 ]. Many studies have reported the mutagenic and carcinogenic effects of PAHs and chronic metabolite exposure as described by the European Food Safety Authority [ 16 ].…”
