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 ...

BN/BO Doping of peri‐Acenoacenes: Modulating Excited States in Trapeziumene Congeners
Angewandte Chemie, Volume 137, Issue 44, October 27, 2025.A new family of (2,5,4)‐trapeziumenes bearing NBNBN, NBOBN, OBNBO, and OBOBO doping patterns is synthesized. Progressive N→O substitution enables precise control over the excited‐state landscape, increasing the S1 energy, decreasing the T1 energy, and widening the T2–T1 energy gap.

Waste tyres pyrolysis oil (WTPO) as an alternative source of fuel and chemicals: a review
Zaštita MaterijalaWaste tyres are dumped and common kind of abandon solid waste. Almost 3 billion tyres are produced each year and each tyre produced will eventually join the waste products and if not properly handled will become pollutant.

Bioaccumulation surveillance in Milford Haven Waterway [PDF]
, 2011 Biomonitoring of contaminants (metals, organotins, PAHs, PCBs) was carried out along the Milford Haven Waterway (MHW) and at a reference site in the Tywi Estuary during 2007-2008. The species used as bioindicators encompass a variety of uptake routes -

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.

Contribution of traffic and tobacco smoke in the distribution of polycyclic aromatic hydrocarbons on outdoor and indoor PM2.5 [PDF]
, 2010 Traffic emissions and tobacco smoke are considered two main sources of polycyclic aromatic hydrocarbons (PAHs) in indoor and outdoor air. In this study, the impact of these sources on the level of fine particulate matter (PM2.5) and on the distribution

Adsorption of Helium on Cationic or Anionic Tetracene and Pentacene
Small Structures, Volume 7, Issue 1, January 2026.How does the arrangement of helium atoms that are adsorbed on tetracene or pentacene ions change with increasing coverage? When does the adsorption layer change from 1D to 2D, and to 3D? Is the transition abrupt? Are the helium atoms localized? Is the arrangement the same for cations and anions? What changes as the acene grows in length?
