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.

Chemical sensor resolution requirements for near-surface measurements of turbulent fluxes [PDF]

Atmospheric Chemistry and Physics, 2011
Businger and Delany (1990) presented an approach to estimate the sensor resolution required to limit the contribution of the uncertainty in the chemical concentration measurement to uncertainty in the flux measurement to 10 % for eddy covariance ...

Scalable Fabrication of Electrochemical Sensors Via Inkjet Printing of Functionalized Graphene for Pesticide Detection

Advanced Materials Technologies, Volume 11, Issue 1, 8 January 2026.
Inkjet printing enables uniform, reproducible, and stable deposition of nitrogen‐doped graphene acid (NGA) on screen‐printed electrodes, outperforming traditional drop‐casting. The resulting electrochemical sensor exhibits enhanced sensitivity, long‐term stability, and efficient imidacloprid detection.

Lie Algebraic Modeling of Vibrational Frequencies in Hexachlorobenzene: A Symmetry-Adapted Approach for the D₆ₕ Point Group

East European Journal of Physics
This work uses a symmetry-adapted Lie algebraic framework to study the vibrational frequencies of hexachlorobenzene (C₆Cl₆). A U(2)-based vibrational Hamiltonian captures the fundamental modes and the first and second overtones by exploiting the molecule'

Protective Roles of Prebiotics and Probiotics Against Environmental Pollutant‐Induced Toxicities: A Systematic Review of Animal Studies

Molecular Nutrition &Food Research, Volume 70, Issue 1, January 2026.
Pollutant‐induced epithelial damage also leads to a cascade of harmful effects, including reduced mucus secretion, decreased luminal pH, and enhanced absorption of toxins. These changes contribute to oxidative stress (↑ malondialdehyde (MDA); ↓ superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), glutathione peroxidase (GPx), and heightened ...

Combining Insecticides and Bioinputs With Eucalyptus Wood Vinegar: Effects on the Soybean Crop

Advances in Agriculture, Volume 2026, Issue 1, 2026.
The use of pesticides and bioinputs in agriculture is one of the most vital needs today to improve crop yields. A combination of pesticides and bioinputs, along with natural agents, is a viable solution to make agribusiness more eco‐friendly. Wood vinegar (WV) is a recognized agricultural input that enhances plant growth and can act as a valuable agent
