Abstract The potentially harmful effects of consuming toxic elements (PTEs) and microplastics (MPs) regularly via drinking water are a significant cause for worry. This study investigated PTEs (Cd, Cu, Cr, Ni, Pd, Zn, Co), MPs, turbidity, pH, conductivity, health risk assessment in the treatment plant Kielce, Poland. Zn had highest concentrations throughout facility, whereas Cd, Pb, Co lower (< 0.1 µg/L). order among specified was like Zn˃Cu˃Ni˃Cr˃Cd˃Pb Co. minimum turbidity 0.34, maximum 1.9 NTU. range pH samples 6.51—7.47. conductivity 1,203—1,445 ms samples. These identified MPs were categorized into fiber fragments. color these blue, red, black, green, transparent. size 196 4,018 µm, while average 2,751 ± 1,905 µm. concentration per liter 108.88 55.61. listed C, O, Na, Mg, Al, Si, K, Ca, Ti.

Published: March 4, 2025

The increased levels of microplastics and nanoplastics (MNPs) found in human brain tissue are alarming, particularly patients with dementia. Although total avoidance MNP exposure will likely remain an unattainable endpoint light their ubiquity the environment, new studies indicate feasible pathways by which dietary intake may be decreased or clearances improved. This commentary reviews evidence on to MNPs, penetration, potential health effects, neurotoxicity. We explore evidence-based strategies for reducing through lifestyle changes while addressing key gaps our current knowledge calling additional research.
