Article Abstract
We assessed the levels of fecal contamination and the originating species of 12 major inland pollutants in the drainage basin of Yeoja Bay. The presence of the human-specific (HF183), ruminant-specific (BacR and Rum-2-Bac), pig-specific (Pig-Bac-2 and Pig-2-Bac), avian-specific (GFD), and gull-specific (Gull2) markers in water samples (n = 34) from 12 inland pollution sources around Yeoja Bay was analyzed. HF183 was detected in 97% of the water samples, and all major inland pollution sources were contaminated with human feces. BacR and Rum-2-Bac were detected in 94% and 11%, respectively, of the water samples. Pig-2-Bac was not detected in the inland pollution sources, but site L5 might be contaminated with swine feces. Gull2 was not detected, whereas GFD was detected in 26% of the water samples. This study highlights the utility of a MST toolbox approach for characterizing the water quality of inland pollution sources and identifying the feces producing species.

Mitigating salinity and cadmium stress in rice ( L.) using PGPR and salicylic acid: rhizosphere, health risk, and physiological insights.

Soil contamination with salinity and heavy metals such as cadmium (Cd) is becoming a serious global problem due to the rapid development of the social economy. Although plant growth-promoting rhizobacteria PGPR and organic agents such as salicylic acid (SA) are considered major protectants to alleviate abiotic stresses, the study of these bacteria and organic acids to ameliorate the toxic effects of salinity and Cd remains limited. Therefore, the present study was conducted to investigate the individual and combined effects of PGPR and SA on enhancing the phytoremediation of salinity (100 mM NaCl) and Cd (50 µM CdCl₂) using rice ( L.

Accurately characterizing the spatial distribution of heavy metals in lake surface sediments, analyzing their sources, and identifying potential ecological risks are important scientific supports for lake ecosystem management. This study selected Dongping Lake, a typical inland shallow lake in the eastern region, as the research object. It systematically analyzed the distribution characteristics, source identification, and ecological risks of eight heavy metals (As, Zn, Cu, Ni, Cd, Hg, Pb, and Cr) in the sediments of Dongping Lake by employing a combination of statistical analysis, cluster analysis, principal component analysis (PCA), and positive matrix factorization (PMF) models, along with the enrichment factor method, geoaccumulation index method, and potential ecological risk assessment method.

Scientists have investigated the thermal tolerance of organisms for centuries, yet the field has not lost relevance as the environmental threats of thermal pollution and global change sharpen the need to understand the thermal vulnerability of organisms in landscapes increasingly subjected to multiple stressors. Freshwater fish and invertebrates are greatly underrepresented in recent large-scale compilations of thermal tolerance, despite the importance of freshwaters as a crucial resource and as havens for biodiversity. Therefore we compiled ThermoFresh, a thermal tolerance database for these organisms that includes literature from 1900 until the present, sourced from five languages to counteract geographic bias.

This study evaluates the potential human health risks of environmental pollutant loads carried by consumption of roach (Rutilus rutilus, Linnaeus, 1758), a bioindicator of environmental pollution from the Cyprinidae family in freshwater systems. We analyzed the concentrations of 26 potentially toxic elements (PTEs) in the muscle, gills, and liver, and 18 organochlorine pesticides (OCPs) in the muscle of roach originating from reservoirs (artificial lakes) with different uses (power generation and water supply) and anthropogenic impacts. Elemental concentrations were compared to maximum allowable concentrations and used to calculate pollution indices, including the metal pollution index and liver/muscle Hg index, health risk and benefit indices (target hazard quotient-THQ, target cancer risk-TR, Se:Hg, Na:K, and Ca:Mg ratios), and contributions of selected trace elements and macronutrients in roach meat.

Marine litter (ML) has ubiquitous occurrence and severe environmental impacts, amplified in highly urbanized areas. This study provides the first year-long assessment of ML along the Iranian Caspian Sea coast. From January to December 2022, monthly surveys were conducted across 12 beach sites, resulting in the collection and classification of 15,389 items.
