“…These results can indicate that in the presence of GO-PEI (Hg+GO-PEI and remediated seawater treatments) Hg is not as easily accumulated at 22 • C as it is at 17 • C, a result that will need further investigation. Similarly, Leite et al [86] demonstrated that Mytilus galloprovincialis presented the highest accumulation of rutile at 18 • C compared to 22 • C. The authors explained that at higher temperature the lowest accumulation could be explained by higher precipitation of larger aggregates limiting the availability and accumulation of the contaminated particles. Nevertheless, higher accumulation of metals in bivalves under temperature rise in comparison to control temperature was previously observed in mussels (M. galloprovincialis) exposed to As [20], which was also associated with increased metabolic activity in these species.…”

“…Afterwards, organisms were gradually dehydrated from ethanol 70% to absolute alcohol in graded alcohols, cleared in xylene, embedded in paraffin (56-58 • C), and serial sections (7 µm thick) were obtained using a microtome as described in Pinto et al [85]. Histopathological alterations in gills and digestive tubules were identified as described previously [86,87].…”

Marine organisms are frequently exposed to pollutants, including trace metals, derived from natural and anthropogenic activities. In order to prevent environmental pollution, different approaches have been applied to remove pollutants from waste water and avoid their discharge into aquatic systems. However, organisms in their natural aquatic environments are also exposed to physico-chemical changes derived from climate change-related factors, including temperature increase. According to recent studies, warming has a negative impact on marine wildlife, with known effects on organisms physiological and biochemical performance. Recently, a material based on graphene oxide (GO) functionalized with polyethyleneimine (PEI) proved to be effective in the remediation of mercury (Hg) contaminated water. Nevertheless, no information is available on the toxic impacts of such remediated water towards aquatic systems, neither under actual nor predicted temperature conditions. For this, the present study assessed the toxicity of seawater, previously contaminated with Hg and remediated by GO-PEI, using the clam species Ruditapes philippinarum exposed to actual and a predicted temperature conditions. The results obtained demonstrated that seawater contaminated with Hg and/or Hg+GO-PEI induced higher toxicity in clams exposed to 17 and 22 °C compared to organisms exposed to remediated seawater at the same temperatures. Moreover, similar histological and biochemical results were observed between organisms exposed to control and remediated seawater, independently of the temperatures (17 and 21 °C), highlighting the potential use of GO-PEI to remediate Hg from seawater without significant toxicity issues to the selected marine species.

Plastic pollution and ongoing climatic changes exert considerable pressure on coastal ecosystems. Unravelling the combined effects of these two threats is essential to management and conservation actions to reduce the overall environmental risks. We assessed the capacity of a coastal ecosystem engineer, the blue mussel Mytilus edulis , to cope with various levels of aerial heat stress (20, 25, 30 and 35°C) after an exposure to substances leached from beached and virgin low-density polyethylene pellets. Our results revealed a significant interaction between temperature and plastic leachates on mussel survival rates. Specifically, microplastic leachates had no effect on mussel survival at 20, 25 and 30°C. In turn, mussel survival rates significantly decreased at 35°C, and this decrease was even more significant following an exposure to leachates from beached pellets; these pellets had a higher concentration of additives compared to the virgin ones, potentially causing a bioenergetic imbalance. Our results stress the importance of adopting integrated approaches combining the effects of multiple environmental threats on key marine species to understand and mitigate their potential synergistic effects on ecosystem dynamics and resilience in the face of the changing environment.

“…It is a measurement of the concentration of hydrogen ions in water, indicating the sample's acidity. It is measured on a scale of 0 to 14, with 7 being the midpoint and is neutral, whereas a pH [42] above 7 is alkaline and becomes more alkaline as it reaches 14; a pH [43] below 7 is acidic and becomes more acidic as it reaches 0 value. pH with a value of 7; hence, non-acidic and non-alkaline is considered as perfectly drinkable water.…”

One of the significant issues that the world has faced in recent decades has been the estimation of water quality and location where safe drinking water is available. Due to the unexpected nature of the mode of water contamination, it is not easy to analyze the quality and maintain it. Some machine-learning techniques are used for predicting contaminating factors but there is no technique that can predict the contamination using latitude, longitude, and elevation. The main aim of this paper is to put factors such as water body location and elevation, which are used as inputs, into the different machine-learning techniques that predict the contamination. The results are reviewed and analyzed according to groundwater contamination and the chemical composition of the groundwater location. Non-changeable factors such as latitude, longitude, and elevation are used to predict pH, temperature, turbidity, dissolved oxygen hardness, chlorides, alkalinity, and chemical oxygen demand. Such a study has not been conducted in the past where location-based factors are used to predict the water contamination of any area. This research focuses on creating a relationship between the location base factors affecting the water contamination in a given area.
