Ecological risk assessment of heavy metals (Pb, Cd, Cr, Ni, Zn, Fe) and metalloid (As) in surface sediment of Anzali International Wetland, Iran

Geology Ecology and Landscapes, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 19

Published: July 2, 2024

This study aimed to assess the metal concentration, mobility, bioavailability, ecological risk, and toxicity in surface sediment of Anzali International Wetland. Contamination risk were evaluated using parameters such as Global Factors (GCF), Risk Assessment Code (RAC), Toxic Unit (TU), sum Units (ΣTUs), Index (TRI), (ER), (RI), modified Hazard Quotients (MHQ). Heavy mean concentrations (mean ± SD) ranked follows: Zn (95.46 20.71) > Cr (19.79 2.79) Ni (18.49 5.23) Pb (13.97 3.20) As (6.45 1.87) Cd (0.90 0.34). exhibited high mobility while Cr, Pb, Zn, Ni, mainly existed residual fractions, indicating low bioavailability minimal risk. Ecological assessment identified "moderate" "considerable" potential for at specific sites. The categorized having "low" (150 < RI 300). Values RI, ΣTUs, MHQ suggested moderate sediment. Factor (GCF) values indicated contamination (12.53 79.11). Recommendations include installing effective sewage treatment plants promoting proper agricultural practices mitigate Wetland also protect human environmental health.

Distribution, Sources, and Ecological Risk Assessment of Potentially Toxic Elements in Surface Sediments of Dongzhai Harbor, Hainan Island, China

Minerals, Journal Year: 2025, Volume and Issue: 15(4), P. 349 - 349

Published: March 27, 2025

The mangrove wetland ecosystem functions as a natural purifier and significant repository for pollutants, effectively facilitating the transfer transformation of contaminants into sediments. This study focuses on Dongzhai Harbor Hainan Island, aiming to investigate spatial distribution patterns, pollution status, potential sources, ecological risk levels potentially toxic elements (PTEs) (Cu, Pb, Zn, Cr, Cd, Ni, As) in surface sediments region. sediment quality area generally complies with Marine Sediment Quality Standards. Results from contamination factor (CF), load index (PLI), geoaccumulation (Igeo), (RI) indicate that Cu are primarily derived sources. In contrast, Cd As exhibit mild moderate levels, likely influenced by anthropogenic activities. is identified primary element pollutant area, presenting low level. mean range effects-median quotient (M-ERM-Q) hazard (HQ) toxicological profiles there some toxicity PTEs area. research provides valuable references prevention control wetland.

Wetland shrinking and dust pollution in Khuzestan Iran: insights from sentinel-5 and MODIS satellites

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: April 20, 2025

Dust pollution is a major environmental issue that threatens public health and ecosystems. This study investigates the relationship between wetland area reduction intensification of dust in southwestern Iran, utilizing satellite data from Landsat, Sentinel-5, MODIS (2010-2022). High-resolution imagery Google Earth Engine (GEE) was used to extract event frequency data, while Aerosol Optical Depth (AOD) Absorbing Index (AAI) were employed monitor levels. Normalized Difference Water (NDWI) analysis revealed Hoor Al-Azim Shadegan wetlands experienced their driest conditions 2010, 2011, 2021, 2022. A strong inverse correlation observed frequency, with coefficients - 0.85 for 0.90 Shadegan. When dropped below 60 km2, events increased 20-35 occurrences. Similarly, Shadegan, exceeded 20 when fell 100 km2. Wind rose indicated prevailing northeast northwest winds, combined dry northern parts significantly contribute formation. Furthermore, established clear number polluted days both PM10 PM2.5. For each 1 km2 decrease area, by 0.03, explaining 56% variation, PM2.5 0.05, accounting 64%. Principal Component Analysis (PCA) further demonstrated changes explain 87.5% 90.1% variance levels, respectively. These findings highlight critical role preservation mitigating improving air quality.
