Summary: PPCPs, including human-derived pharmaceuticals, are becoming ubiquitous in the environment from various sources. A study conducted in Murcia, Spain, measured the presence of selected pharmaceuticals in water and sludge, showing good degradation of IBU and NPX, no degradation of CBZ, and DIC being most likely to be sorbed into sludge. The study also compared the removal efficiency of a double step activated sludge wastewater treatment plant with a single biological batch reactor, indicating a decrease in removal due to lower hydraulic retention time. Risk assessment showed low risk of the selected pharmaceuticals to humans and ecosystems.

Summary: Water and water management, including wastewater treatment plants (WWTPs), are essential elements of critical infrastructure. This article discusses the application of risk management stages on a municipal WWTP facility through a case study, focusing on risk identification and analysis. A combination of methods, including safety audit, checklist, and semi-structured interviews, was used to identify and assess risks, resulting in the identification of undesirable and unacceptable risks.

Summary: In this study, the soil at a former coking wastewater treatment plant site in Taiyuan, northern China, was analyzed to detect the presence of 16 types of priority polycyclic aromatic hydrocarbons (PAHs) listed by the US EPA and evaluate the pollution risks. The results showed that the surface soil of the redeveloped land had a wide range of PAHs, mainly consisting of high-ring components. Pollution was mainly related to the combustion of petroleum, coal, and biomasses. The assessment of ecological risk indicated that the pollution was potentially harmful to the environment, but the cancer risk for different populations was within acceptable limits based on average PAH concentrations.

Summary: Wastewater treatment plants have a significant impact on the abundance and diversity of antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs) in downstream river water, but have less influence on sediment. WWTPs contribute more to ARGs in river water compared to sediment. TnpA has been identified as a key factor for the dissemination of ARGs, and P. aeruginosa, E. cloacae, and E. coli are critical hosts for ARGs.

Summary: This research examined the occurrence and removal of micro-plastics (MPs) in a waste treatment plant (WWTP) in Hefei, China. The findings showed that the abundance of fibrous MPs was highest in WWTP sewage and sludge. The composition of MPs was found to be strongly influenced by human activities and environmental conditions.

Summary: In order to study the occurrence and spatial distribution of antibiotics in the Nanming River in Guiyang, China, 27 water samples were collected. Twelve antibiotics were analyzed using solid phase extraction (SPE) combined with ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), and a total of eight antibiotics were detected, indicating the prevalence of antibiotics in the study area. The total antibiotic concentrations ranged from 2.3 to 1097.4 ng/L and fluoroquinolones were found to be the dominant antibiotics.

Summary: Mycological contamination of food products is a common issue in the food industry, which can impact consumer health. Red wine, despite its potential health benefits, can also contain toxic substances like ochratoxin A. A study found that mycotoxin levels in dry red wines exceeded limits, with differences based on country of origin and farming methods. The levels of T-2 and HT-2 toxins were negatively correlated with pH in the wines. Further research is needed to establish reference values for various mycotoxins in different types of food, including wine.

Summary: This study assessed the sediment quality of Tijuca Lagoon in Rio de Janeiro, Brazil and found contamination and toxicity, such as PAHs and heavy metals, in the sediments. While PAH and metal concentrations were not significantly correlated with the mortality of burrowing amphipods, domestic sewage contributions and eutrophication had a significant impact on sediment toxicity.

Summary: This study aimed to evaluate sediment pollution loadings and ecological risks, with three objectives. Through hierarchical clustering and principal component analysis, it was found that wetlands are most affected during the post-monsoon season, with most sites falling under moderate risk category. Cd was identified as the primary contributor to ecological risk. Chemical speciation analyses revealed different heavy metals' availability forms in sediment, highlighting the negative impact of Cr, Mn, and Mg on aquatic ecology.

Summary: This study conducted a large-scale investigation of per- and polyfluoroalkyl substances (PFASs) in 44 wastewater treatment plants in Shaanxi Province, China. The results showed that these plants are major sinks for PFASs, but they also act as secondary point sources, releasing PFASs into the environment. The study also found that the composition profiles of PFASs differed between wastewater and sludge samples, and the removal efficiency varied for different chain lengths of PFASs.

Summary: The study investigated VSC emissions and ambient air exposure concentrations in an A(2)/O WWTP, proposing control strategies based on sulfate concentrations and chemical oxygen demand in the wastewater. Results indicated that emissions were significantly affected by these parameters and efforts should be made to reduce emissions. In ambient air, MT and DMS were identified as the main odorous components.

Summary: This study collected sediment samples from the west and south of Peninsular Malaysia to measure the concentration of linear alkylbenzenes (LABs) and determine their sources. The results showed that LAB concentrations in the areas under investigation ranged from 67.4 to 255.8 ng g(-1) dw. Statistical analysis indicated significant differences in LAB homologs, with a large number of C-13-LAB homologs present at most sampling sites. The study also revealed that treated sewage from both main and secondary sources was released into the study areas, as indicated by the LAB ratio (I/E) ranging from 1.6 to 4.1. Moreover, LAB degradation ranged from 33 to 64% in the studied regions. It is concluded that upgrading the wastewater treatment system is necessary, and the use of LAB molecular markers is essential for tracing anthropogenic sewage contamination.

Summary: Cytostatic drugs are commonly found in wastewater effluents due to their poor biodegradability, but the Fe(III)-EDDS complex has shown to efficiently degrade cyclophosphamide and 5-fluorouracil under solar light. The addition of EDDS widens the operational pH range of the solar photo-Fenton process, and a suitable Fe(III):EDDS ratio and initial dissolved oxygen level impact the degradation performance. Rapid degradation of the drugs was achieved within 1.5 minutes in the solar photo-Fenton process, with potential for total mineralization under relatively low Fe(III) concentration and H2O2 dosage.

Summary: This study investigates the enhanced degradation of BT and 5-MeBT during the sunlight/free chlorine process. The results show that sunlight/free chlorine treatment can enhance the degradation of BT and 5-MeBT, especially under alkaline conditions. The enhanced removal is attributed to the generation of HO • and reactive chlorine species (RCSs).
