Summary: This study analyzed the spatial and temporal distribution of phosphorus fractions in water-sediment phases in the Tuojiang River and the relationships among different phosphorus fractions. This study found that soluble reactive phosphorus (SRP) and phosphorus bound by Fe oxides (Fe-P) were the dominant phosphorus fractions in the water and sediment, respectively. The total phosphorus (TP) content was higher in the lower reaches of the river. Most phosphorus fractions in the water-sediment phases showed significant seasonal variations, and Fe-P, Org-P, and TP in sediments were released to the water interface, leading to an increase in phosphorus in the overlying water. The physicochemical properties of water and sediment influenced the spatial-temporal distribution of phosphorus fractions, and anthropogenic activities were identified as the main phosphorus source.

Summary: In this study, biochar-supported molybdenum dioxide was used as a co-catalyst to enhance the activation ability of Fe3+ on persulfate for the degradation of Bisphenol A. The results showed that over 96% of BPA was removed within 60 minutes, and the degradation efficiency only slightly decreased after four reuses of the co-catalyst. The study also revealed that biochar supports the adsorption of Fe3+ on the MoO2 surface and promotes electron transfer. This work provides a new insight for improving the degradation of organic contaminants in wastewater.

Summary: Recently, the increase in environmental pollution worldwide due to human activities has become a concern. Plants, being part of the biota, can serve as bioindicators of global pollution as they have the ability to assimilate compounds in the air, water, and soil, and respond to changes in their surroundings. However, the monitoring ability of urban plants regarding organic pollutants in air, soil, and water has not been extensively studied. This study focused on the anthropogenic contamination produced by five different types of pollutants in Riyadh and Abha areas in Saudi Arabia and found that wild and ruderal plants have high detection frequencies of polycyclic aromatic hydrocarbons (PAHs), pharmaceuticals and personal care products (PPCPs), perfluoroalkyl substances (PFASs), pesticides, and organophosphorus flame retardants (OPFRs). The results suggest that these plants can be used as bioindicators to monitor anthropogenic contaminants in the terrestrial environment.
