Summary: Graphene oxide (GO) is gaining attention for its unique properties and increasing use in consumer products. There is a concern that GO will end up in oceans and potentially affect marine organisms. This study evaluated the hazards of GO and benzo(a)pyrene (BaP) in marine mussels after exposure, finding that GO acts as a carrier for BaP but may also offer some protection against BaP accumulation.

Summary: Here, a facile and selective synthesis of cationic azatriphenylene derivatives was achieved through electrochemical intramolecular cyclization, where the key step involves atom-economical C-H pyridination without a transition-metal catalyst or an oxidant. This proposed strategy provides a practical approach for introducing cationic nitrogen (N (+)) into pi-electron systems, thus expanding the molecular design of N (+)-doped polycyclic aromatic hydrocarbons.

Summary: In this study, CeO2-based porous carbonaceous frameworks (CeO2 PCFs) were used as antioxidant nanozymes to scavenge reactive oxygen species and absorb benzo[a]pyrene. CeO2 PCFs exhibited excellent superoxide dismutase-like and catalase-like activity, effectively eliminating superoxide radical, hydroxyl radical, and hydrogen peroxide. The 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) free radical scavenging assay confirmed the free radical scavenging ability of CeO2 PCFs. Furthermore, CeO2 PCFs with large surface area and porous structure efficiently adsorbed benzo[a]pyrene. The designed CeO2 PCFs can serve as new antioxidant nanozymes for scavenging reactive oxygen species and adsorbing polycyclic aromatic hydrocarbons (PAHs).

Summary: In this study, we conducted single-molecule spectroscopy at cryogenic temperatures to investigate the optical properties of graphene quantum dots (GQDs). We found that temperature has an effect on the spectral characteristics of GQDs, and we used density functional theory calculations to explain these observations. Additionally, we discovered that the vibrational features can serve as a unique fingerprint for identifying GQDs.

Summary: The South African government has established national norms and standards for the assessment of waste for landfill disposal, including the evaluation of PAHs in sediment and sludge samples. The study found that the PAHs were primarily of petrogenic origin and exceeded the acceptable concentration levels in river sediments, posing potential risks to aquatic organisms and dermal exposure for inhabitants in the area. Continuous monitoring of these compounds is therefore crucial.

Summary: This study investigated the spatiotemporal distribution, source, and ecological risk of PAHs and SPAHs in surface sediments in Laizhou Bay. The results showed seasonal differences in concentrations of PAHs and SPAHs and a spatial distribution trend of estuary > coast > offshore. Combustion sources, including petroleum, coal, and biomass, were identified as the main contributors to PAHs and SPAHs. The risk level of PAHs was low-to-moderate, while SPAHs posed a moderate-to-high ecological risk.

Summary: This study documents the geographical and temporal differences in the occurrence of microplastics in water and fish samples collected near Giglio Island in the North Tyrrhenian Sea. The results show site-dependent differences in water samples, indicating the role of surface currents in the local distribution of microplastics. The size of the Neuston nets used did not affect the retention efficiency of microplastics. Fish samples in 2019 had a higher frequency of microplastic ingestion compared to 2017, and the occurrence was higher than in other Mediterranean areas. Fragments were the most dominant shape, with polypropylene and polyethylene being the prevalent polymers, showing no significant differences between sites and years. This study highlights the importance of conducting microplastic investigations in both living and non-living matrices for effective monitoring of marine pollution.

Summary: The Augusta Bay in eastern Sicily, Italy, is a highly impacted coastal environment with elevated levels of contaminants due to industrial activities. The concentrations of mercury and hexachlorobenzene were found to be high in sediments and showed strong bioaccumulation in different species. However, after the closure of the chlor-alkali plant in 2003, the bioavailability and biological effects of these contaminants gradually decreased. The persistence of mercury and hexachlorobenzene in the environment has implications for the health of marine organisms and possible risks to human health.

Summary: Cigarette butts (CBs) are a common form of litter on beaches and represent an unexplored environmental threat. This study investigated the toxicological risks of CBs on marine organisms through chemical analyses and a variety of biological responses. The results showed that CBs released trace metals, hydrocarbons, nicotine, and cotinine, which significantly impacted bacterial bioluminescence, oyster embryo development, and algal growth. Laboratory experiments on mussels exposed to CBs also revealed accumulation of chemicals and significant alterations in immune, antioxidant, and neurotoxic responses.

Summary: The cost of RNA-sequencing has decreased, allowing for new insights into the adverse effects of chemicals on aquatic organisms. However, the qualitative application of transcriptomics in environmental risk assessments limits its effectiveness. In this study, a quantitative methodology is proposed to elaborate transcriptional data in support of environmental risk assessment. The methodology uses Gene Set Enrichment Analysis to calculate a hazard index based on changes in gene sets and physiological reactions. This approach has proven to effectively discriminate different levels of altered transcriptomic responses and can be applied to other aquatic species.

Summary: A study investigated the potential negative impacts of the delousing treatment used in aquaculture on the marine environment. Laboratory experiments were conducted to study the acute and sublethal effects of exposure on northern shrimp. Environmental concentrations were determined by water sampling and sediment analysis. Ecotoxicological analyses revealed high sensitivity of the shrimp to the delousing treatment, and field measurements and modeling predicted concentrations that could cause negative effects on the shrimp up to a certain distance from the point of release.

Summary: This study compares microplastic contamination in two crustaceans, the European spiny lobster and the langoustine. Samples were collected from four sites in west Sardinia, Italy. The results show that both species are 100% contaminated with microplastics, with the spiny lobster being significantly more contaminated. The scavenging-based feeding strategy of these species could explain their exposure to microplastics, which are mostly derived from single-use plastic.

Summary: This study investigated the interactions between two commonly detected pharmaceuticals in marine species: carbamazepine (CBZ) and valsartan (VAL). The results revealed complex mechanisms that modulate bioaccumulation, excretion, and toxicity. The gene expression, neurotransmission, cell cycle, immune responses, and redox homeostasis were affected by the drugs. The Weight of Evidence model showed a higher reactivity of CBZ compared to VAL and antagonistic interactions between the compounds, resulting in reduced effectiveness when combined with valsartan. Overall, this study provides new perspectives for the comprehensive risk assessment of environmental pharmaceutical mixtures.

Summary: Echinoderms, particularly sea urchins and sea cucumbers, are important in marine ecosystems and are widely used as biological indicators due to their sensitivity to stressors. However, there is limited knowledge about the comparative responsiveness of sea cucumbers. This study aimed to investigate the responsiveness of different echinoderm species to environmental pollution and found species-specific sensitivities to pollutants. Sea cucumbers were found to be more sensitive than sea urchins when exposed to contaminated sediments. These findings suggest that using different echinoderm species in bioassays can provide a comprehensive assessment of the effects of contaminants in ecotoxicological studies.
