Summary: This study compared the toxic effects of CuPT and ZnPT on embryonic olive flounder and found that CuPT had a greater toxicity than ZnPT with respect to developmental malformation and mortality. Furthermore, gene expression analysis revealed that CuPT exposure affected genes associated with tail fin malformation, cellular respiration, and kidney development, while ZnPT exposure affected genes related to cell development, nervous system development, and heart development.

Summary: The encapsulation of antifouling compound DCOIT in mesoporous silica nanocapsules has been proven to be an eco-friendly alternative with reduced toxicity towards marine non-target species. However, the chronic effects of such nanomaterials on non-target tropical species have not been well studied, posing challenges for environmental risk assessment.

Summary: In-water cleaning (IWC) removes biofilms and foulants from ship hulls, but can release harmful chemical contaminants and cause hotspots of contamination in coastal areas. We investigated the toxic effects of IWC discharge on embryonic flounder and found that zinc, copper, and zinc pyrithione were dominant contaminants. Discharge from IWC caused developmental malformations and affected genes related to muscle and nervous system development in non-target coastal organisms.

Summary: The study shows that Brevibacillus laterosporus has significant lethal effects on Asian tiger mosquito larvae and non-target water-dwelling species with concentration-dependent activity. While mosquito larvae are highly susceptible to the bacterial infection, there were no effects on preimaginal development stages and adult emergence at sub-lethal spores' concentrations.

Summary: Environmental spills of in-water hull cleaning wastewater (HCW) containing heavy metals and biocides can significantly impact microalgal community, especially depending on spill volume. The growth of unattached microalgae was significantly affected by HCW dose, while the biomass of attached microalgae increased with HCW dose, which was associated with nutrient reduction. Our findings suggest the importance of managing spills of HCW to protect marine ecosystems.

Summary: Copper pyrithione (CuPT) exhibits marked toxicity towards early life stages of fish, leading to high accumulation of copper in larvae. It induces higher larval mortality and greater effects on larval development and growth compared to CuSO4, and requires higher concentrations to induce expression of genes involved in oxidative stress defence, detoxification, and copper transport.

Summary: Tyrosine kinase inhibitors (TKIs) are drugs designed for targeted cancer therapy, and their consumption has been steadily increasing in the past 20 years. In a zebrafish embryo toxicity test, the toxicity of six TKIs was assessed. The study found that imatinib mesylate and dasatinib induced lethal effects, while regorafenib, sorfenib, and dasatinib caused significant sub-lethal effects, mainly manifested as edema, no blood circulation, and formation of blood aggregates. Furthermore, the study demonstrated that exposure to these TKIs disrupted the expression of genes associated with the hormone system. These findings suggest that TKIs may pose environmental hazards and further ecotoxicological studies are needed.

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: Since the late 70s, the environmental impact of pharmaceuticals, especially antineoplastic agents, has raised concerns about human and environmental health. In this study, a systematic review was conducted to gather ecotoxicological information of antineoplastic agents on freshwater species from microorganisms to vertebrates. The study also analyzed the sensitivity distribution curves and estimated the hazard concentration to assess the ecological risk. Lastly, suggestions were made to improve the Environmental Risk Assessment of antineoplastic agents, including adopting toxicity endpoints, testing duration, metabolites testing, and mixture exposure.

Summary: This study investigated the toxicokinetics of engineered nanoparticles in Chironomus riparius, showing that absorption of silver nanoparticles (Ag NPs) was higher in the simulating aged form (Ag2S NPs) compared to pristine Ag NPs and AgNO3. Water uptake was the main route of Ag accumulation, and chironomid larvae exhibited a strong ability to accumulate Ag. This is the first study on the toxicokinetics of nanoparticles in Chironomus, providing important insights into their exposure and interactions in the environment.

Summary: The present study aimed to assess the ecotoxicological effects of Zinc-Aluminium LDH-nitrate (Zn-Al LDH-NO3) in zebrafish early life stages. The results showed that Zn-Al LDH-NO3 had no observable acute effects on zebrafish embryos and larvae, but caused malformations in embryos and affected locomotor behavior in larvae. However, no significant biochemical and molecular changes were recorded. Overall, Zn-Al LDH-NO3 can be regarded as a non-toxic nanomaterial towards zebrafish.

Summary: Sustainability, circularity, and Zero Waste policies are important concepts for policy development and strategies. Insects can play a crucial role in converting waste into valuable materials and have potential as food products. This study investigated the bioaccumulation kinetics of mercury in two insect species, Tenebrio molitor and Hermetia illucens. The results showed that both insects can regulate mercury effectively and eliminate it quickly after being transferred to clean substrates. These findings provide important information for insect producers regarding product safety and the depuration time required for processing and commercialization.

Summary: The health risks to wild fish exposed to pollution from multiple sources are mainly caused by metal contamination from mining activities and organic contamination from other sources. The biomarkers response in fish is affected by seasonal variations. Integrating chemical data with suitable biomarkers is an effective strategy to assess ecological risks in the Doce River Basin. It is necessary to protect the river ecosystem and wildlife.

Summary: This study aimed to compare the effects of different exposure methodologies on the ecotoxicological profile of different powder grain sizes of Zn-Al LDH-NO3 and Cu-Al LDH-NO3. The results showed that the serial dilutions methodology was preferable for Zn-Al LDH-NO3, while both methodologies were suitable for Cu-Al LDH-NO3. Thus, the serial dilutions methodology was selected to assess the ecotoxicity of different grain sizes for both LDHs. All Zn-Al LDH-NO3 grain sizes yielded similar toxicity, while smaller grain sizes of Cu-Al LDH-NO3 had a greater effect on microalgae growth.

Summary: This study aimed to quantify the concentrations of inorganic and organic contaminants in the Doce River Basin (DRB) and evaluate their spatial and temporal variations and associations with potential anthropogenic sources. The results showed that trace elements were higher in the Upper DRB close to mining activities, while organic contaminants like PAHs were introduced by industrial effluents and urban centers along the DRB. Seasonal variation was found to influence the distribution of chemicals, with the wet season increasing levels of trace elements in the water. The intense mineral exploitation and dam failure disaster were responsible for the increased levels and spread of inorganic contaminants, while other sources contributed to the contamination scenario.
