This study investigated whether oxidative stress-mediated mitochondrial dysfunction contributes to GEN-induced apoptosis in TM4 mouse Sertoli cells and ELT3 rat leiomyoma cells. Cells were exposed to GEN (30 or 100 µM) for 48 h. Cytotoxicity, oxidative stress, mitochondrial function, and apoptosis were assessed by measuring cell viability, lactate dehydrogenase release, reactive oxygen species (ROS), malondialdehyde, glutathione reductase activity, mitochondrial membrane potential (ΔΨm), intracellular ATP, apoptosis-related gene expression, and caspase-3/-9 activities. The involvement of oxidative stress was examined using N-acetyl-L-cysteine (NAC). GEN reduced cell viability, antioxidant capacity, ΔΨm, and ATP content while increasing membrane damage, ROS accumulation, and lipid peroxidation in both cell lines. These changes were accompanied by upregulation of Bax, Tp53, caspase-3, and caspase-9; downregulation of Bcl-2; and increased caspase-3/-9 activities. NAC pretreatment attenuated these alterations, supporting ROS as an upstream mediator. Notably, TM4 cells were approximately 4.4-fold more sensitive to GEN than ELT3 cells at 48 h.

The arsenic Health Risk Index (HRI) screening classification was derived entirely from drinking-water measurements collected in a preceding regional study during 2022-2024; no water samples or exposure biomarkers were obtained in the present survey. The questionnaire-derived potential exposure index was calculated as the unweighted sum of seven binary indicators covering residential, drinking-water, occupational, dental, and dietary characteristics (theoretical range, 0-7; observed range, 0-6) and was analyzed continuously. Symptom count (theoretical range, 0-8) was analyzed primarily using negative binomial regression with locality-clustered standard errors and adjustment for age, sex, smoking, alcohol consumption, HRI classification, and self-reported comorbidity. Each one-point increase in the potential exposure index was associated with a modestly higher expected symptom count (adjusted incidence rate ratio = 1.106, 95% CI: 1.031-1.186; <i>p</i> = 0.005), whereas the area-level HRI classification was not statistically associated with symptom count (adjusted incidence rate ratio = 1.135, 95% CI: 0.829-1.554; <i>p</i> = 0.431).

Key contamination vectors include raw materials, manufacturing equipment, facilities, packaging, personnel activities, utilities, processing aids, cleaning residues, and process design deficiencies. While solid oral dosage forms can encapsulate particulates, liquid formulations present a heightened ingestion risk. To combat these vulnerabilities, advanced analytical techniques-such as Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy with energy-dispersive X-ray spectroscopy, and X-ray fluorescence-are evaluated alongside emerging artificial intelligence-driven detection and real-time monitoring systems.

Human studies report polymer-confirmed particles or polymer-associated signals in blood, urine, and kidney-related specimens, supporting systemic presence and compatibility with renal exposure; however, estimates are strongly method-dependent and do not establish anatomical localization, tissue dose, clearance, or a disease threshold.

Effects vary with polymer, size, shape, surface ageing, route, dose, and chemical co-exposures, and many experiments remain difficult to map to typical human exposure. Direct human outcome evidence is limited to cross-sectional or exploratory studies; plasticizer epidemiology is informative for chemical co-exposure but cannot establish particle-specific toxicity. Patients with chronic kidney disease may be more susceptible, while kidney dysfunction may also alter measured blood or urinary concentrations.
