Summary: The study evaluated the occurrence of 24 Polycyclic Aromatic Hydrocarbons (PAHs) in sediments and shellfish of Todos os Santos bay (BTS, Brazil), indicating moderate contamination from pyrogenic activities. Different species showed varying bioaccumulation factor (BAF) for total PAHs, with high molecular weight compounds enriched in species living in fine sediment and low molecular weight compounds enriched in species living in the roots of mangrove trees. High concentrations of PAHs raise concerns about shellfish quality and seafood consumption safety.

Summary: Mercury pollution in the ocean, particularly in marine apex predators like Greenland halibut, has been a global concern. A study on Greenland halibut showed a decrease in Hg bioaccumulation in fillet tissue over a ten-year period, with methylmercury being the predominant form. The decrease in Hg concentrations was attributed to factors such as declines in Hg air emissions, estimated trophic position, and trophic shifts in the food web dynamics.

Summary: Anthropogenic activities contribute significantly to atmospheric Hg emissions. Oceanic predator fishes in the marine habitat bioaccumulate Hg, with human exposure mainly through consumption. This study analyzed publications from 1973 to 2022 to investigate Hg contamination in different fish species, finding higher Hg concentrations in sharks compared to bony fishes. While different regions were identified, overall Hg concentrations did not show significant differences. The study also highlighted the risks of consuming these species, as some individuals exceeded safety limits set by health agencies worldwide.

Summary: Reusing reclaimed wastewater is crucial for combating water scarcity and conserving water resources, but it is important to ensure the removal of hazardous substances before reuse. This study evaluated the potential of lab-scale constructed wetlands (CWs) in removing chemical and biological contaminants from livestock wastewater while maintaining nutrient levels for fertilization. The results showed that CWs effectively removed heavy metals, organic matter, and bacterial contamination from the wastewater, making it suitable for agricultural reuse. The microbial communities in the CWs demonstrated adaptation and removal potential, highlighting the potential of CWs in sustainable liquid waste treatment and promoting circular economy.

Summary: This study investigated the fate of trace metals in anaerobic digestion of municipal solid waste (MSW) digestate-amended soil and the influence of pharmaceutical compounds on their behavior. The results showed that trace metals initially present in the digestate were transferred from the amended soil layer to the underlying soil layer over time, but no transfer was detected to deeper soil layers. Trace metals in soil were mostly in immobile and less bioavailable forms, while in the digestate-amended soil they were in more bioavailable forms. The presence of the antidiabetic drug metformin had no influence on trace metal behavior.

Summary: Drinks are a significant source of human exposure to plasticizers like OPEs. This study analyzed OPE levels in various drink samples and found that tap water had higher levels compared to packed water, possibly due to PVC water pipes. Regular cola drinks had the highest OPE concentrations, particularly EHDPP. Although OPE exposure was below safety limits, the potential health risks from regular cola drinks, juice, and tap water should not be ignored, and other exposure routes should also be considered.

Summary: Donana National Park (DNP) is a protected area known for its diverse bird species. However, the use of pesticides in the surrounding agricultural practices has led to contamination of the park's bird eggs, with detrimental effects on their health and reproduction. A study conducted over a span of more than twenty years (1999-2021) identified 26 pesticides in the collected bird eggs, including commonly detected organochlorine and newly detected pyrethroid pesticides. The concentrations of these pesticides varied, with some exceeding levels known to be harmful to avian species. The findings call for control measures to limit pesticide use and further investigation into the impact on bird populations in this protected area.

Summary: This study investigated the bio-degradation kinetics of tetramethyl bisphenol F (TMBPF), a non-estrogenic alternative to bisphenol A (BPA). Batch biotransformation experiments were performed using activated sludge and liquid chromatography-Orbitrap-MS for BTP identification. Results showed that TMBPF degradation followed first-order reaction kinetics and depended on the initial concentration. Twelve BTPs were identified, and a proposed biodegradation pathway for TMBPF was suggested.

Summary: This study tested a bioremediation approach with tide stimulation to degrade buried and surface oil contamination, focusing on two, three, and four rings polycyclic aromatic hydrocarbons (PAHs). Linear models showed degradation constants of individual PAHs as a simple additive function of their initial concentrations (C0), hydrophobicity, sampling layer, and treatment conditions. Oil degradation in buried layers was faster than at the surface for all PAHs and treatment conditions. Naturally-occurring microorganisms were efficient in bioremediating PAHs and were stimulated by fertilizer addition (biostimulation, BS). Bio-augmentation (BA) with a slurry of pre-stimulated native oil-degrading consortium did not enhance PAH degradation compared to BS. Degradation was more rapid for PAHs with low initial concentrations and intermediate hydrophobicity. Bioremediation of beach sand with either surface or buried crude oil is a cost-effective strategy for cleaning up various hydrocarbon families, including persistent ones like PAHs.

Summary: Concerns about plastic pollution, especially microplastics, have increased due to their presence in various environmental areas. The present study aims to investigate the role of saltmarshes in trapping microplastics by comparing microplastic concentrations in vegetated and non-vegetated sediments. Microplastics were detected in all sediment samples, with fibres being the most common type. Vegetated sediments, especially those of saltmarsh species Juncus maritimus, contained a higher number of plastic items. These findings suggest that saltmarshes play a significant role in the transport and accumulation of microplastics in estuarine areas.

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.

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.
