Pesticide contamination in wastewater poses a significant environmental challenge, driven by extensive agricultural use. This study evaluates the removal of chlorpyrifos (CPS) using sugarcane bagasse-based biochar alginate beads in a continuous fixed-bed adsorption column, achieving a remarkable 95-98% removal efficiency. Compared to conventional adsorbents like activated carbon, which typically show CPS adsorption capacities ranging from 50-70 mg g⁻ under similar conditions, the biochar alginate beads demonstrate better performance with a sorption capacity of 91.

A former uranium recovery facility located in northwestern New Mexico currently serves as a uranium mill tailings site undergoing reclamation and decommissioning. High velocity winds are common in the area, causing soil erosion via aeolian processes. Strong winds may carry soil for several kilometers, which is redeposited downwind.

Precise prediction of adsorption in a multicomponent system is vital for successful design of dye-contaminated industrial wastewater treatment processes. The present work looks for the reason behind the failure of the competitive Langmuir model (CLM) to describe adsorption in such systems, while the Langmuir model (LM) successfully describes the process for a single dye solution. With that end, derivations of LM and CLM have been revisited, and a criterion for the universality of active sites has been defined.

Dual-impulse behaviors of rolling bearings have been widely researched for quantitative diagnosis. However, it is challenging to accurately extract entry and exit moments of the fault from noise-contaminated raw signals. To address this issue, a novel quantitative diagnosis method based on digital twin model is proposed to assess the fault severity from the original signal waveform.

Objective: the research is to determine the main radiation-hygienic factors influencing the formation of radiation doses among the population of radioactively contaminated territories (RCT) in Zhytomyr region in 2024 and to analyze the dynamics of internal radiation doses based on original experimental studies conducted in reference settlements from 2012 to 2024.
Materials And Methods: In 2024, a comprehensive radiation-hygienic monitoring program was conducted in 11 settlements of Narodychi Territorial Community (TC): the Narodychi and the villages of Selets, Bazar, Rudnya Bazarska, Khrystynivka (Zone 2), Motiyki, Zalissya, Davydky, Radcha, Nova Radcha, and Grezlya (Zone 3). The comprehensive radiation-hygienic monitoring included the following activities: mobile WBC monitoring: 817 measurements (562 adults and 255 children); collection and analysis of food samples: 39 milk samples, 61 potato samples, and 57 samples of wild foods, analyzed for radionuclide content, including 137Cs and 90Sr; assessment of external radiation exposure in these settlements; surveys: 194 individuals were surveyed regarding the consumption volumes of locally produced foods from their own households and purchased foods from commercial networks.
