Summary: The occurrence and impacts of emerging organic contaminants in Chinese surface water have been studied using a multi-criteria screening approach. The study developed a prioritization scheme based on hazard and exposure potentials to identify the top-priority and high-priority pollutants. The priority index effectively captured and integrated the results from other prioritization schemes based on exposure potential, hazard potential, or risk quotients.

Summary: Emerging pollutants and priority substances, such as polycyclic aromatic hydrocarbons (PAHs) and PCBs, were detected in sediments from both Cartagena Bay and the Grand Marsh of Santa Marta. While some sites in Cartagena Bay exceeded threshold effects levels for PAHs, none of the stations in the marsh did. The cytotoxicity of HepG2 cells exposed to sediment extracts showed a negative correlation with chlorpyrifos concentration, indicating specific contamination fingerprints related to anthropogenic interventions in these ecosystems.

Summary: Individual variability in drug response (IVDR) is a major cause of adverse drug reactions (ADRs) and prolonged therapy. In addition to genetic background, the gut microbiota and its metabolites also play an important role in modulating therapeutic outcomes. The emerging field of pharmacomicrobiomics aims to explore the correlation between microbiota variation and IVDR or ADRs.

Summary: A synthetic bacterial consortium capable of efficiently degrading six priority phthalate esters (PAEs) was designed and constructed. This consortium showed efficient degradation of PAEs in both minimal inorganic salt medium (MSM) and soil. Therefore, this microbial consortium is a strong candidate for the bioremediation of environments contaminated with mixed PAE pollutants.

Summary: The genomics revolution has had a significant impact on rare disease (RD) research, but there are still common challenges and unmet needs for the RD population globally. RDs have been marginalized in healthcare systems and policies. The COVID-19 pandemic has highlighted the inequalities faced by the RD population, emphasizing the need to address these disparities across populations and jurisdictions.

Summary: This study reports the synthesis and characterization of Sn-doped ZnAl hydrotalcite through the coprecipitation method and evaluates its performance in photocatalytic degradation of acetaminophen. The results show that the ZnAl/ZnSn(OH)6 composite exhibits better degradation efficiency under UV light. Additionally, by adjusting the ratio of ZnAl/ZnSn(OH)6 and the pH value of the solution, the photocatalytic efficiency can be further improved.

Summary: This review emphasizes the importance of bioremediation techniques for the removal of emerging pollutants. These pollutants are chemical or biological substances that are currently not monitored or regulated, but can have harmful effects on the environment and human health. To achieve sustainable remediation, recent research has focused on advanced biological remediation technologies, such as those involving plants, bacteria, microalgae, and fungi. The review compiles the latest studies to expand our understanding of sustainable remediation technologies and presents research opportunities based on current challenges.

Summary: In this study, the single and combined toxicity of microplastics (MPs) and organic pollutants on Chlorella pyrenoidosa were investigated. The results showed that the combined impact of UV-aged MPs and organic pollutants had a significant damaging effect on algae cells. This research verified the remarkable combined toxicity between UV-aged MPs and organic pollutants on microalgae.

Summary: Standardised microalgal toxicity assays with bisphenol A showed differences in sensitivity among three marine microalgae species, with Phaeodactylum tricornutum being the most affected and Nannochloropsis gaditana being the least affected. Significant differences were observed between single- and multispecies bioassays for some species, but overall, a similar pattern of alterations was observed in both types of toxicity tests.

Summary: The quantification of SARS-CoV-2 RNA load in wastewater has emerged as a useful tool to monitor COVID-19 outbreaks in communities. This approach was implemented in the metropolitan area of A Coruna, where wastewater analysis helped track the epidemic dynamics. Regression models allowed estimation of the number of infected individuals and served as an effective early warning tool for predicting outbreaks in the municipality.

Summary: Pharmaceutical active compounds (PhACs), such as ibuprofen (IBU) and oxytetracycline (OTC), are a growing concern due to their ubiquitous presence and harmful impact on aquatic ecosystems. In this study, the cyto- and genotoxic effects of IBU, OTC, and their binary mixture on Chlamydomonas reinhardtii were investigated. The results showed that the binary mixture caused the most severe damages, including decreased cell proliferation and metabolic activity, increased intracellular ROS levels, and depolarization of cytoplasmic and mitochondrial membranes. Additionally, elevated caspase-like and endonuclease activities and a loss of nuclear DNA integrity were observed. The findings suggest that programmed cell death (PCD) is an important toxicological target for understanding the harmful effects of co-exposure to PhACs in aquatic organisms.

Summary: Benzophenones (BPs), widely-used UV-filters, have been found to alter the physiology of the freshwater microalga C. reinhardtii. RNA-Seq analysis revealed that BPs affected cellular metabolic pathways and gene expression. Both BP-3 and BP-4 caused changes in gene expression, with BP-3 having a higher number of differentially expressed genes. The findings suggest that BPs impair photosynthesis and lead to a shift towards heterotrophic metabolism in microalgae.
