This study evaluated the concentrations, sources, and health risks of trace metals metalloids in effluents 15 wastewater treatment plants (WWTPs) located along Black Sea Marmara, ecologically economically vital regions Türkiye. Effluent samples were collected winter autumn, metal concentrations analyzed using ICP-MS to assess seasonal variations potential risks. Results showed notable regional differences, with aluminium (Al) nickel (Ni) as most abundant metals. The highest total concentration was recorded autumn at station S2 (326.09 mg/L). Non-carcinogenic negligible (HI< 1) across all stations, but low carcinogenic (10 -6 < CRi ≤ 10 -4 ) for chromium (Cr) detected some locations. Source apportionment Principal Component Analysis revealed mixed geogenic anthropogenic origins, primarily from industrial activities urban runoff. While generally complied national standards, several exceeded international limits, highlighting ecosystems human health. These findings underscore urgent need stricter discharge regulations, improved technologies, continuous monitoring mitigate environmental impacts WWTP discharges.

The present study aimed to investigate the occurrence of eight potentially toxic elements (PTEs) in selected varieties watermelon (Citrullus lanatus var. Arka Shyama and Crimson Sweet) muskmelon (Cucumis melo Cantaloupe Kajri) grown near riverbanks Yamuna Ganga River basins Northern India. For this purpose, samples melon fruits were collected from ten sampling sites May June 2024 analyzed using ICP-OES. results showed that levels PTEs varied significantly across sites, with muskmelons exhibiting slightly higher concentrations compared watermelons. Specifically, concentration (mg/kg dry weight) ranges for Cd (0.05–0.20), Cr (0.40–1.10), Cu (1.50–4.90), Pb (0.01–0.11), As (0.01–0.08), Fe (80.00–120.00), Mn (9.00–15.80), Zn (5.00–18.00). muskmelons, (0.05–0.23), (0.40–1.00), (2.40–4.80), (0.02–0.08), (80.00–120.00 g), (9.00–15.00), (8.00–18.00). In particular, variability coefficients (CV%) indicated differential contamination Sweet. On other hand, Principal Component Analysis (PCA) Hierarchical Cluster (HCA) tools facilitated identification significant their respective interactions. health risk studies index (HRI), dietary intake modeling (DIM), target hazard quotient (THQ) also revealed no fruits. Therefore, provides valuable insights into biomonitoring PTE widely consumed summer India subsequent assessment.

The accumulation of heavy metals in the ecosystem due to industrialization has led toxic effects on various life forms such as flora, fauna and microfauna. Several approaches that are currently used for removal not cost-effective efficient. Therefore, current study was focused bio-removal chromium (Cr), lead (Pb) zinc (Zn) using augmentation with strong biofilm forming Bacillus infantis (VITVJ8), which confirmed by augmented rhizosphere region Chrysopogon zizanioides a percentage 0.025%. bioremoval process catalyzed superoxide dismutase, chromate reductase catalase activity 83U/ml, 51U/ml 75U/ml, respectively.

The present study investigated the uptake and health risks of potentially toxic elements (PTEs) by lotus (Nelumbo nucifera) cultivated in floating lake gardens Dal Lake, Srinagar, India. Rapid urbanization anthropogenic activities have led to PTE contamination lake, raising concerns about food safety ecological sustainability. objectives were evaluate physicochemical properties water sediment quantify PTEs (Cd, Cu, Cr, Co, Fe, Mn, Ni, Zn) accumulation different tissues N. nucifera with associated risks. A systematic sampling approach was adopted across four zones collecting water, sediment, plant (August October 2024). results showed significant contamination, showing high concentrations Fe (1610.51 mg/kg), Mn (31.48 Cr (29.72 mg/kg). Bioaccumulation factors indicated preferential roots, exhibiting highest (95.11). Translocation low for most PTEs, suggesting limited mobility edible parts. Health risk assessment that posed non-carcinogenic (HRI = 1.8000 rhizomes). cumulative target hazard quotient (THQ) remained below 1, no immediate risk, but long-term exposure warrants concern. provided valuable information on necessity continuous monitoring pollution mitigation strategies ensure garden-derived crops.
