Polychlorinated naphthalenes in the air over the equatorial Indian Ocean: Occurrence, potential sources, and toxicity

, 2016
Monitoring of marine polychlorinated naphthalenes (PCNs) is crucial, as they are considered persistent organic pollutants (POPs) by the Stockholm Convention. Data on PCNs in marine environment are scarce.

Volatile Organic Compounds in Rainwater: A New Frontier in Atmosphere–Biosphere Interactions

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Rainwater is a key vector of atmospheric deposition, linking the atmosphere with terrestrial and aquatic ecosystems. While the inorganic chemistry of precipitation (dominated by sulfate, nitrate, ammonium, and trace metals) has been extensively studied, organic compounds in rainwater have received less attention, and Volatile Organic Compounds

Atmospheric Deposition of Organic Pollutants: A Comprehensive Review of Sampling and Analytical Methodologies

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Atmospheric deposition of organic pollutants plays a crucial role in the transport and fate of contaminants in the environment, with implications for ecosystem health and human exposure. Persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs) and microplastics are increasingly recognized as transboundary threats due to ...

Exposures in Indoor Air Affecting Health

Allergy, Volume 81, Issue 3, Page 700-719, March 2026.
ABSTRACT Indoor air quality (IAQ) is influenced by a wide range of chemical, biological and physical agents that can negatively impact physical, immunological and mental health. Adverse health effects depend on the type and concentration of pollutants, duration of exposure, and individual susceptibility.

Sequential Carbon–Carbon/Carbon–Selenium Bond Formation Mediated by Iron(III) Chloride and Diorganyl Diselenides: Synthesis and Reactivity of 2‑Organoselenyl-Naphthalenes

, 2017
In this paper, we report an intramolecular cyclization of benzylic-substituted propargyl alcohols promoted by iron­(III) chloride and diorganyl diselenides to give 2-organoselenyl-naphthalenes via a sequential carbon–carbon/carbon–selenium bond formation.

Silicone Wristbands for Measuring Human Exposure to Organic Chemicals: Uses and Benefits for Human Biological Research

American Journal of Human Biology, Volume 38, Issue 2, February 2026.
ABSTRACT Increasing human exposure to environmental contaminants is a growing concern and has become an important factor within human biological variation and health outcomes. Yet, traditional exposure assessment methods are often limited in their ability to capture the complexity and variation of chemical exposure, or are invasive, costly, and ...

Tracking the fingerprints and combined TOC–black carbon mediated soil–air partitioning of polychlorinated naphthalenes (PCNs) in the Indus River Basin of Pakistan

, 2016
This study reports the first investigation of polychlorinated naphthalenes (PCNs) in air and soil samples from ecologically important sites of the Indus River Basin, Pakistan. The concentrations of ∑39-PCNs in air and soil were found in a range between 1–

Evaluation of the pollution pressures posed by groups of chemicals on British riverine invertebrate populations

Biological Reviews, Volume 101, Issue 1, Page 106-127, February 2026.
ABSTRACT Globally, rivers receive a diverse range of chemicals, including metals, pesticides, persistent organic pollutants, petrochemicals, human and veterinary pharmaceuticals and personal care products. However, the extent to which these different chemical groups affect riverine invertebrate communities is not well defined.

Degradation of Polychlorinated Biphenyl Metabolites by Naphthalene-Catabolizing Enzymes [PDF]

Applied and Environmental Microbiology, 1998
ABSTRACT The ability of the dehydrogenase and ring cleavage dioxygenase of the naphthalene degradation pathway to transform 3,4-dihydroxylated biphenyl metabolites was investigated. 1,2-Dihydro-1,2-dihydroxynaphthalene dehydrogenase was expressed as a histidine-tagged protein.

Re‐evaluation of sucralose (E 955) as a food additive and evaluation of a new application on extension of use of sucralose (E 955) in fine bakery wares

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract The present opinion deals with the re‐evaluation of sucralose (E 955) as food additive and with the safety of a proposed extension of use in food category (FC) 7.2 ‘Fine bakery wares’. Based on the available data, no safety concerns arose for genotoxicity of sucralose (E 955) and its impurities and degradation products.
