Summary: International Public Health authorities recommend biomonitoring studies to assess chemical exposure in the general population. This study analyzed blood concentrations of various pollutants in a cohort of subjects from Cape Verde and found that 16.7% of the 360 toxic compounds were detected in at least one participant. The study also identified the most frequently detected substances and the factors influencing blood concentrations. This is the first biomonitoring study in Cape Verde and provides useful information for public health measures.

Summary: The study found that organochlorine pesticides and PCBs are still prevalent in Eurasian otters in UK freshwaters, despite a decline in concentrations over the years. Higher concentrations of pollutants were found in the Midlands and Eastern regions, as well as near the coast, which may pose a risk to otters and other freshwater predators. Despite legislative controls, these legacy pollutants continue to impact otters and exceed thresholds for reproduction and survival in related species.

Summary: Persistent organic pollutants (POPs) accumulated in the body may be associated with the incidence of certain diseases. This study investigated the association between the concentration of POPs and circulating metabolites in human blood samples. The findings suggest that metabolites related to short-chain fatty acids and creatine can be useful risk indicators for estimating the effect of PCB exposure.

Summary: This study assessed the prevalence of persistent organic pollutants (POPs) in breast milk of lactating mothers in Lebanon, finding dichlorodiphenyldichloroethylene (DDE) as the only detected pollutant. Factors such as pre-pregnancy body mass index, age, and dietary habits were associated with DDE contamination. The study highlights the need for monitoring policies, good agricultural practices, and education programs for breastfeeding mothers.

Summary: This study measured the biomagnification of persistent organic pollutants (POPs) in organisms from adjacent terrestrial and aquatic environments. The results showed that the biomagnification of polychlorinated biphenyls (PCBs) was consistent in both food webs, while short-chain chlorinated paraffins (SCCPs) had higher biomagnification potential in terrestrial than aquatic organisms. The different processes and influencing factors in biomagnification of POPs in aquatic and terrestrial food webs were determined, including the respiratory elimination for terrestrial organisms and the different metabolism rates in various species. The fugacity model was found to predict levels of less hydrophobic chemicals accurately, but more precise toxicokinetic data of SCCPs are needed.

Summary: A study was conducted to assess contamination by persistent organochlorine pollutants (POPs) in the surficial sediments of Lake Piediluco in the Central Italian Apennines. The results showed a substantial zonation of pollution within the lake, with varying concentrations of OCPs and PCBs. However, the concentrations were relatively low and posed a low risk to the aquatic ecosystem.

Summary: This study measured serum concentrations of persistent organic pollutants (POPs) in women in the Euro-Arctic Region of Russia, finding that legacy POPs concentrations were low and similar to other Arctic countries. Significant geographic differences between settlements, and between Nenets and non-Nenets residents, were observed. Additional Arctic biomonitoring research in Russia should focus on nutrition and POPs concentrations associations.

Summary: Reports on levels of persistent organic pollutants (POPs) in Antarctic seabirds based on blood are scarce. This paper fills a significant data gap in the Antarctic region by presenting levels of legacy POPs and novel brominated flame retardants in the blood of Antarctic seabird species. The results show that legacy POPs are still present in Antarctic wildlife despite long-term bans, and trace levels of new POPs were also detected.

Summary: Mitochondria are organelles responsible for cellular oxidation and energy production, and their damage can lead to changes in mtDNA copy number. Exposure to TCDD and a mixture of PCB 126 and PCB 153 increased mtDNA copy number in the liver and lung of rats, while exposure to non-DL PCB 153 resulted in decreased or unchanged mtDNA copy number. This suggests that mtDNA copy number could serve as a sensitive biomarker of mitochondrial injury and oxidative stress caused by dioxin-like compounds.

Some acute cases of SARS-CoV-2 infection require long-term oxygen therapy, and the infection has a significant impact on short-term functional status. A considerable number of MHS beneficiaries had not returned to normal activities by 1 month post-infection.

Summary: This study investigated the acute mental health symptoms and tobacco initiation among nonlocal responders involved in the Deepwater Horizon oil spill response. The results showed that female responders were more likely to experience concurrent depression and anxiety symptoms, while tobacco initiation was negatively associated with age and officer rank. These findings suggest that the oil spill response work has an impact on the mental health and behavior of responders, highlighting the importance of addressing the mental health needs of nonlocal responders and implementing appropriate interventions.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

Summary: Air pollution is associated with a range of health issues and gestational exposure to environmental pollutants may be linked to neurodevelopmental disorders. This study investigated the effects of oral gestational exposure to particulate matter (PM) on ultrasonic vocalizations (USV). The findings suggest that this exposure may lead to social deficits and abnormal gene expression related to neurotransmitter systems. Further research is needed to better understand the effects of air pollution on neurodevelopmental disorders and the neurotransmission systems involved.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.

Summary: The selection of predictor variables is crucial in building a digital mapping model for potentially toxic elements (PTEs) in soil. Traditionally, spatial and spectral parameters have been used as predictor variables, but the temporal dimension is often overlooked. This study demonstrates the value of incorporating temporal indices in the model, leading to significant performance improvements. The temporal-spatial-spectral covariate combinations used in a random forest (RF) algorithm achieve satisfactory mapping accuracy and outperform other methods.

In this study, a series of catalysts with different elemental doping were prepared using a simple and environmentally friendly method. The S-doped NiCo2O4 catalyst showed excellent catalytic performance for the removal of Tetracycline, with significantly increased kinetic constant and high oxidation and mineralization efficiency in a wide pH range. The degradation process was dominated by non-radical oxidation pathway after S doping, and the overall process moved towards low toxicity.
