Characterization of colloidal particles in soils, sediments and sludges by single particle inductively coupled plasma mass spectrometry: a comparative study using sector field and time-of-flight instruments
Li, Z., Hadioui, M. and Wilkinson, K.J. J. Analytical Atomic Spectrometry 2025, 40, 2487-2497 https://doi.org/10.1039/D5JA00181A Abstract Colloids and nanoparticles in solid phase environmental matrices (soils, sediments, sludges) are widely heterogenous and polydisperse, which complicates their sampling and characterization by bulk analysis techniques. Indeed, techniques based upon single particle measurements are better equipped for identifying important, […] Lire la suite

Competitive interactions among the rare earth metals (lanthanum, cerium, and yttrium) lead to quantitative decreases in biouptake by Chlamydomonas reinhardtii
Laurianne Pagé, Marie-Hélène Brunet and Kevin J. Wilkinson Environmental Pollution 2025, 373, 126170 https://doi.org/10.1016/j.envpol.2025.126170 Abstract With increasing mining and production of the rare earth elements (REE), it is important to quantify their potential environmental impacts. The objective of this study was to quantitatively relate REE biouptake to exposure under carefully controlled laboratory conditions. Internalization fluxes […] Lire la suite
