Article
Carbon dioxide capture and storage (CCS) in submarine geological formations has been proposed as a mitigation measure for the prevention of global warming. However, leakage of CO2 to overlying sediments may occur over time, leading to various effects on ecosystems. Laboratory-scale experiments were performed, involving direct release of carbon diox...

Sunscreens contain ZnO particles used as a UV filter cause adverse effects in the marine environment through the release of this metal into seawater and its bioaccumulation in organisms. A mathematical model using sunscreen colloidal residues, seawater and R. philippinarum clams as differentiated compartments, is proposed in order to interpret both...

Iron plays a crucial role in the high-nutrient, low-chlorophyll Southern Ocean regions, promoting phytoplankton growth and enhancing atmospheric carbon sequestration(1–5). In this area, the recycling of biogenic iron is partially driven by the iron-rich Antarctic krill (Euphausia superba), and baleen whale species as one of their main predators(6–1...

Surgical face masks are more present than ever as personal protective equipment due to the COVID-19 pandemic. In this work, we show that the contents of regular surgical masks: i) polypropylene microfibres and ii) some added metals such as: Al, Fe, Cu, Mn, Zn and Ba, may be toxic to some marine life. This work has got two objectives: i) to study th...

Penguins dominate the Antarctic avifauna. As key animals in the Antarctic ecosystem, they are monitored to evaluate the ecological status of this pristine and remote region and specifically, they have been used as effective bioindicators suitable for long-term monitoring of metals in the Antarctic environment. However, studies about the role of thi...

Alkali-activated binders (AABs) stand out as a sustainable alternative to ordinary Portland cement (OPC) as they can be formulated using by-products or waste as raw materials. However, the presence of hazardous compounds in residues can lead to an increase in AABs' toxicity due to the highly alkaline media. Therefore, it is extremely important to e...

Ice-nucleating particles (INPs) have a large impact on the climate-relevant properties of clouds over the oceans. Studies have shown that sea spray aerosols (SSAs), produced upon bursting of bubbles at the ocean surface, can be an important source of marine INPs, particularly during periods of enhanced biological productivity. Recent mesocosm exper...

Sunscreen is released into the marine environment and is considered toxic for marine life. The current analytical methods for the quantification of sunscreen are mostly specific to individual chemical ingredients and based on complex analytical and instrumental techniques. A simple, selective, rapid, reproducible and low-cost spectrophotometric pro...

Microplastic particles (MP) uptake by marine organisms is a phenomenon of global concern. Nevertheless, there is scarce evidence about the impacts of MP on the energy balance of marine invertebrates. We evaluated the mid-term effect of the microplastic ingestion at the current higher environmental concentrations in the ocean on the energy balance o...

The Mediterranean Sea, which is considered a biodiversity hotspot, is, by far, the leading tourism destination in the world, receiving more than 267 million international tourists in 2017, and producing a high anthropogenic pressure on its natural environment. The arrival of these tourists is mainly concentrated during the summer season when the us...

Numerous biogeochemical studies in the Southern Ocean have focused on the importance of trace metals in controlling primary production (e.g. Fe, Co) or as potentially toxic to the ecosystem (e.g. Ag, Cd). However, the reasons why Fe limitation is prevalent in the Southern Ocean or the concentrations of non-biogenic elements in surface waters are hi...

Carbon capture and storage has become a new mitigation option to reduce anthropogenic CO2 emissions. The effects of the CO2-related acidification, associated with unpredictable leaks of CO2 during the operational phases were studied using the Paracentrotus lividus sea urchin-liquid-phase-assays (fertilisation and embryo-larval development tests). B...

The capture and storage of CO2 in sub-seabed geological formations has been proposed as one of the potential options to decrease atmospheric CO2 concentrations in order to mitigate the abrupt and irreversible consequences of climate change. However, it is possible that CO2 leakages could occur during the injection and sequestration procedure, with...

Little is known of the capacity that marine metazoans have to evolve under rapid pCO2 changes. Consequently, we reared a marine polychaete, Ophryotrocha labronica, previously cultured for approximately 33 generations under a low/variable pH regime, under elevated and low pCO2 for six generations. The strain usedwas found to be tolerant to elevated...

Nowadays, there is a significant increase in the presence of emerging pollutants in the marine environment. Among these new chemical products, many of them are related to personal care and skincare products (e.g., ultraviolet filters, antimicrobial, antiseptics, plastic microbeads, etc.), which reach the coastal ecosystem, principally, through wastewater treatment plants (WWTPs). Although analytical methods have been developed for their quantification in different environmental matrices, there is a lack of information on these compounds concerning their fate and behavior in the marine environment and, specifically, about their bioaccumulation and toxicity in aquatic species. This Special Issue (SI) will bring specialists from different disciplines to fill this gap of information, taking into account the complexity of the marine environment and the occurrence of species belonging to different trophic levels and inhabiting different environmental compartments. In summary, this SI represents an opportunity to bring into the scientific arena an important issue about the use of these compounds and their consequences to the environment and to assess the impact of skincare products on marine life. Topics include, but are not limited to: - Environmental quality and risk assessment studies of chemical-related skincare and personal care products in the marine environment. - Potential effects of ingredients contained in personal care and skincare products (e.g., nanoparticles, UV filters, antimicrobial, antiseptics, plastic microbeads, etc.) on marine biota, including different levels of biological organization. - Development of new methodologies and approaches to determine the presence of skincare chemicals in environmental matrices and assess the toxicity related to these contaminants. - Development and application of models to predict or explain the fate and behavior of chemicals released from skincare products in coastal and marine ecosystem. - Discussions about the frontiers of new knowledge that improve our understanding on fate, behavior and toxicity of skincare products in marine and coastal ecosystems. This will be a dynamic Special Issue, and articles will be published as soon as the reviewers and editors are ready to accept them, without waiting for the deadline for the entire Special Issue to arrive. Articles publications are free of cost. More information: https://www.mdpi.com/journal/oceans/special_issues/Skincarechem_marinelife
