Polystyrene foam as a source and sink of chemicals in the marine environment: An XRF study.
Chemosphere, 2021 Polystyrene foam (expanded and extruded polystyrene: EPS and XPS, respectively) is a ubiquitous and pervasive type of marine plastic whose physical properties, transport and fate are distinctly different to those of other common (unfoamed) types of ...

vis–NIR and XRF Data Fusion and Feature Selection to Estimate Potentially Toxic Elements in Soil
Italian National Conference on Sensors, 2021 Soil contamination by potentially toxic elements (PTEs) is intensifying under increasing industrialization. Thus, the ability to efficiently delineate contaminated sites is crucial. Visible–near infrared (vis–NIR: 350–2500 nm) and X-ray fluorescence (XRF:

Quantification of Cu and Zn in antifouling paint films by XRF.
Talanta: The International Journal of Pure and Applied Analytical Chemistry, 2021 Methods to determine the release of biocides (e.g. copper) and substances of concern (e.g. zinc) from antifouling paints are required for both the development of efficient products and their environmental risk assessment.
