ABSTRACT The present study aims to assess surface water quality (WQI), wastewater (WWQI), and the presence of toxic chemicals, including metals endocrine‐disrupting compounds (EDCs), in Saigon River basin. A total 27 samples from nine locations basin 30 10 industrial parks were collected 2023. In addition, Pearson correlation analysis, principal component analysis (PCA), cluster (CA) employed investigate relationships potential sources parameters, heavy metals, EDCs wastewater. Water Quality Index (WQI) revealed that five (S2, S3, S6, S7, S9) classified as poor (WQI: 47–50), while four (S1, S4, S5, S8) exhibited moderate 53–64). For wastewater, three (W2, W3, W7) showed low‐strength (WWQI: 36–40), (W4, W6, W8, W10) had medium‐strength 54–74), (W1, W5, W9) displayed high‐strength 76–80). Pb (0.50 mg/L) Cr (0.10 concentrations higher than limits set by QCVN 08:2023/BTNMT (Pb < 0.02 mg/L 0.05 mg/L). concentration was 0.60 mg/L, 40:2021/BTNMT limit 0.5 highest amount nonylphenol monoethoxylate (NP1EO) found (179.67 ± 24.88 ng/L), octylphenol (OP) (20,000.00 8509.79 ng/L). test a strong positive relationship between bisphenol (BPA) diethoxylate (NP2EO) ( r = 0.80) NP1EO 0.99). identified NP Zn 0.94) BPA 0.96).

Hydrogel beads were constructed using sodium alginate (SA) and banana pith powder (BPP). The ability of to adsorb Copper (Cu2+), Lead (Pb2+) Nickel (Ni2+) was examined SA-BPP ratios (1:1, 1:2, 1:3, 1:4, 1:5, 1:0 0:1).

Riverine heavy metal (HM) pollution, a critical global environmental issue, severely affects water quality, ecosystem health, and human well-being. The Huaihe River, once among China’s most polluted, has seen quality improvements due to strict pollution controls, yet the extent of HM reduction remains uncertain. Here, we investigated distribution, sources, potential ecological health risks nine typical HMs (Cr, Mn, Ni, Cu, Zn, As, Cd, Pb, Hg) in surface sediment Anhui section river. Seasonal variations concentrations were observed, with values below drinking safety limits, except for Mn Cd at specific sites seasons. Indices including HPI, HEI, HQ, HI showed low contamination risks, children are more vulnerable non-carcinogenic hazards, notably from As. Sediment trends decreased as > Zn Cr Pb Ni Cu As Hg, moderate based on CF, EF, Igeo assessments. PLI NPI suggested midstream areas accumulation. correlation analysis PCA revealed that uncontaminated sediments mainly geogenic origin, while contaminated largely influenced by anthropogenic activities, agricultural runoff, industrial waste, domestic sewage discharge. Overall, our findings highlight control activities within River basin is essential reducing

Abstract Sediments in agricultural ecosystems serve as critical indicators of environmental pollution, particularly regions subjected to intensive practices. This research evaluates the hazards and implications heavy metal (HM) contamination river sediments from Sidi Allal Tazi area within Morocco’s Sebou basin. Twenty sediment samples were extracted strategically designated locations, levels analyzed using a multi-index integration approach, multi-statistical analyses (MSA), Geographic Information Systems (GIS). The results revealed considerable spatial variability HM concentrations, with Cd As displaying highest levels. Statistical analysis, incorporating Principal Component Analysis (PCA), identified anthropogenic activities primary contributors contamination. Hierarchical Cluster (HCA) categorized metals based on common pollution pathways, while GIS mapping distribution across vulnerable areas. Pollution like Geo-accumulation Index (Igeo) well Load (PLI). that 75% sites under “very high pollution”, emphasizing severity Contamination Factor (CF) classified 90% 100% contamination”. Risk indices indicated significant ecological threats, contributing an RI exceeding 600 many areas, signifying risk”. These findings highlight urgent need for targeted mitigation strategies sustainable methodologies provides comprehensive framework assessing managing contamination, offering insights policymakers managers.
