π‐Expanded Fluoranthenes as Chromophores With Tailored Properties

Helvetica Chimica Acta, Volume 109, Issue 3, March 2026.
A series of π‐expanded fluoranthene scaffolds selectively functionalized with electron donors and acceptors were synthesized. The evolution of the structural, optoelectronic, and redox properties in relation to substitution and cyclization was comprehensively studied both in experiment and in theory. The results identify the compounds as highly tunable

A comparison of PAH emission sampling methods (cyclone, impactor) in particulate and gaseous phase [PDF]

, 2018
Four different domestic heating boilers and four types of fuel (lignite, wet wood, wood pellets and mixed fuel) were tested, and the emissions of the particulate matter (PM) and polycyclic aromatic hydrocarbons (PAHs) were correlated. Dekati low-pressure

A Data‐Driven Approach Coupled With Physical Constraints to Improve Groundwater Models With Structural Error

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Groundwater models are essential tools for groundwater remediation and contamination risk assessment. However, due to the simplification or inaccurate representation of real‐world groundwater systems, model structural errors are widespread and unavoidable, leading to systematic biases in model predictions.

Safety evaluation of blue galdieria extract as a food additive

EFSA Journal, Volume 24, Issue 3, March 2026.
Abstract The EFSA Panel on Food Additive and Flavourings (FAF Panel) provides a scientific opinion on the safety of blue galdieria extract as a food additive. Blue galdieria extract is an enzymatically treated C‐phycocyanin extract derived from the lysed biomass of the microalgae Galdieria sulphuraria.

Macroinvertebrates, Heavy Metals and PAHs in Urban Watercourses [PDF]

, 2001
Good quality stream water and sediments are crucial for the support of healthy stream flora and fauna but urban runoff degrades watercourses leaving a legacy of pollution in the stream sediments.

Dusty Streets: The Challenge of Dust‐Borne Pollutants in Low‐Income Countries

CLEAN – Soil, Air, Water, Volume 54, Issue 2, February 2026.
Generally, pollution impacts developed and low‐income countries (LICs) to different extents, and the disease burden due to roadway dust is not uniformly distributed across socio‐economic classes. Roadway dust materials from paved and unpaved urban and rural roads were reported to contain organic constituents which are toxic and affect public health ...

Ethyne Furan Ratios as Indicators of High and Low Temperature p-PAH Emissions from Household Stoves in Haryana India

Atmosphere
Emission factors of 16 particle-bound polycyclic aromatic hydrocarbons (16 p-PAHs) from residential fuel combustion are highly variable, resulting in significant uncertainty with respect to the estimation of emissions of PAHs from this sector.

Bacteria-mediated PAH degradation in soil and sediment [PDF]

, 2011
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous in the natural environment and easily accumulate in soil and sediment due to their low solubility and high hydrophobicity, rendering them less available for biological degradation. However, microbial

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.
