“…However, pus can undergo degradation, with the ease of this process being influenced by structural characteristics such as the chemical groups present in the molecular chains, the level of crystallinity, and molecular orientation, among others [15]. According to research conducted by [16], the chemicals present in 55 polymers were identified and classified according to the environmental risk they present, where flexible PU was categorized as one of the most dangerous due to the toxicity, mutagenicity, and carcinogenicity of its monomers, catalysts, and degradation products, such as hydrogen cyanide [17][18][19].…”

The major problems related to environmental pollution are increasingly present among us. The uncontrolled use and incorrect disposal of products means that these problems are increasing at frightening rates. In this context, a major related problem is the incorrect disposal of dishwasher sponges that are no longer useful; their material being made up of petroleum derivatives causes this problem to be leveraged in the environment. In the present work, we evaluated and carried out tests in which these dirty sponges that would be discarded were used for the purpose of developing new sustainable adsorbent materials. These materials were washed and dried, crushed and made available for use, by which they were kept in contact with a paracetamol solution, evaluating the effect of mass, pH, kinetics, equilibrium, thermodynamic parameters, and cost analyses. The results demonstrated an adsorptive capacity of approximately 40 mg g−1 and its cost was relatively viable, since this material would otherwise be discarded incorrectly. In conclusion, this material achieved the good removal of this studied contaminant and became an economical, viable, and ecologically viable material.

Coral reefs are invaluable ecosystems that are under threat from various anthropogenic stressors. There has been a recent increase in the diagnostic tools utilized to understand how these threats impact coral reef health. Unfortunately, the application of diagnostic tools like transmission electron microscopy (TEM) is not as standardized or developed in coral research as in other research fields. Utilizing TEM in conjunction with other diagnostic methods can aid in understanding the impact of these stressors on the cellular level because TEM offers valuable insight into the structures and microsymbionts associated with coral tissue that cannot be obtained with a conventional light microscope. Additionally, a significant amount of coral tissue ultrastructure has not yet been extensively described, causing a considerable gap in our understanding of cellular structures that could relate to the immune response, cellular function, or symbioses. Moreover, additional standardization is needed for TEM in coral research to increase comparability and reproducibility of findings across studies. Here, we present standardized TEM sample fixation, embedding, and sectioning techniques for coral studies that ensure consistent ultrastructural preservation and minimize artifacts, enhancing the reliability and accuracy of TEM observations. We also demonstrate that these TEM protocols allow for the observation and quantification of bacterial and viral‐like particles within the coral tissue as well as the endosymbiotic microalgae, potentially providing insight into their interactions within coral cells and how they relate to overall coral health and resilience. © 2024 The Author(s).
