Microplastics in Freshwater
The low production costs and useful properties of synthetic polymers have led to their ubiquitous use, from food packaging and household products to high-tech applications in medicine and electronics. Incomplete recycling of plastic materials results in an accumulation of plastic waste, which slowly degrades to produce tiny plastic particles, commonly known as “microplastics” (MPs).

Interventions to Reduce Food Waste
Young consumers accept the issue of food waste and have several experiences in their own lives. Even though they see themselves as responsible for the environment and for climate change, they also acknowledge that there is a challenge with food waste in their own household. Interventions based on packaging are seen in different forms, going from studies with the packaging being able to preserve food better to studies where information about food waste prevention is given on the packaging.

Environmental Microplastics
Environmental microplastics are gaining interest due to their ubiquity and the threat they pose to environmental and human health. Critical studies have revealed the abundance of microplastics in nature, while others have tested the impacts of these small plastics on organismal health in the laboratory. Yet, there is often a mismatch between these two areas of research, resulting in major discrepancies and an inability to interpret certain findings. Here, we focus on several main lines of inquiry. First, even though the majority of environmental microplastics are plastic microfibers from textiles, laboratory studies still largely use spherical microbeads. There are also inconsistencies between the measurements of microplastics in the environment as compared to the concentrations that tend to be used in experimental studies. Likewise, the period of exposure occurring in experimental studies and in the environment are vastly different. Lastly, although experimental studies often focus on a particular subset of toxic chemicals present on microplastics, textile microfibers carry other dyes and chemicals that are understudied. They also cause types of physical damage not associated with microspheres.

Sailing Weather Prediction
Weather routing is a commercial service provided by commercial companies for cargo ships, to optimize their voyage performance. An adventure version of the same used for sailing boats is referred to as Sailing weather prediction or Sailing weather routing. The latter focusses more on the forecasting and routing of wind and currents for adventurers and competitive sailors participating in ocean sports like yacht races. Weather forecasting for sailing involves several activities such as weather training and coaching, dissemination of data for use in navigation and route planning software, race modeling which involves historical weather and sea state analysis for yacht and sail design, trip and adventure planning for distance races and record attempts, monitoring for departure and trip weather windows. It involves several type of events such as day races, long-distance races, around-the-world-races, and record attempts. It is routinely used in races such as Volvo Ocean Race, America's Cup campaigns, and olympic classes regattas.

Nitrogen and Phosphorus in the Northern Adriatic Sea
In the last two decades of the 21st century, a gradual decrease in nitrogen and phosphorus has been observed along the coastal area of the Northern Adriatic Sea. This depletion is attributed to reduced river flows. Studies conducted over the past four decades have indicated that the N/P ratio in the open sea is unlikely to undergo significant change. In fact, it tends to increase due to the unique characteristics of the Northern Adriatic Sea, which experiences slow water turnover and is influenced by strong winds. Additionally, the Northern Adriatic Sea receives a substantial amount of freshwater from rivers, accounting for about one-third of the total freshwater flow into the Mediterranean. These rivers carry nutrient loads that contribute to the high productivity and abundance of fish in this sea, making it one of the most productive areas in the Mediterranean. It has been observed that the cessation of anthropogenic phosphorus input, which has been regulated since the late 1980s with legislation limiting its use in detergents, has significantly affected the trophic chain.

Haloarchaea
Haloarchaea has the capability of producing significant concentrations of polyhydroxyalkanoate (PHA), polyhydroxybutyrate (PHB), and polyhydroxyvalerate (PHV) when growing under a specific nutritional status. The growth of those microorganisms at the pilot or industrial scale offers several advantages compared to that of other microbes that are bioplastic producers.

An Appeal to Reason
An Appeal to Reason: A Cool Look at Global Warming is a 2008 book by Nigel Lawson. In it, Lawson argues that global warming is happening, but that the science is far from settled. He opposes the scientific consensus as summarized by the IPCC. He also argues that warming will bring both benefits and negative consequences, and that the impact of these changes will be relatively moderate rather than apocalyptic. The book has been rejected by climatologists, including IPCC authors Jean Palutikof and Robert Watson as unscientific. The book was published in the UK and the USA in 2008. It appeared in Spanish translation the following year, published by Gota a gota, the imprint of the think tank FAES.

Diver-Based Optical Survey Techniques for Coral Monitoring
Monitoring the health of coral reefs is essential to understanding the damaging impacts of anthropogenic climate change as such non-invasive methods to survey coral reefs are the most desirable. Optics-based surveys, ranging from simple photography to multispectral satellite imaging are well established. The techniques are broadly separated by the primary method in which data are collected: by divers and/or robots directly within the environment or by remote sensing where data are captured above the water’s surface by planes, drones, or satellites.

 Aspergillus and Penicillium Species in Biodegradation of Pesticides
Since filamentous fungi of Penicillium and Aspergillus genera can colonize very diverse niches, and Ascomycota seems to be the dominant phylum within the microbial group in various contaminated substrates, they possess great potential in the remediation of pesticide-contaminated sites. Different species can remove the pesticides at different rates, and to various extents; however, the fungal ability to resist high concentrations of pesticides is almost unparalleled compared to other microbial groups. Their performance may be further improved by applying indigenous strains isolated from pesticide-contaminated soils and sediments.

Post-Occupancy Evaluation’s Applications for Improving Indoor Environment Quality
To improve buildings and their characteristics, the feedback provided directly by users is generally fundamental in order to be able to adapt the technical and structural functions to the well-being of users. The post-occupancy evaluation (POE) fits perfectly into this context. The POE, through qualitative and quantitative information on the interior environment, makes it possible to identify the differences between the performances modeled in the design phase and the real performances experienced by the occupants.

Bioactive Metabolites in Liquid State Cultures
Humans have appreciated mushrooms for their edible and medicinal value since the Neolithic age. Increased interest in the pharmaceutical potential of mushrooms has led to numerous publications that explore more than 100 reported medicinal functions. These are functions such as antifungal, antibacterial, antiviral, antioxidant, anti-inflammatory, anti-tumor, antiviral, anti-diabetic, anti-thrombotic, anti-allergic, antidepressive, antihyperlipidemic, digestive, hypotensive, cytotoxic, hepatoprotective, neuroprotective, nephroprotective, osteoprotective, and immunomodulating activities, among others. This therapeutic action is due to a wide array of bioactive metabolites isolated from the fruiting body, mycelium, and culture broth of macrofungi. Both complex high-molecular-weight compounds such as polysaccharides, proteins, and lipids and low-molecular-weight compounds such as terpenoids, polyketides, and alkaloids have been isolated and are under study. In addition to their pharmaceutical potential, mushrooms are recognized as a rich source of nutraceuticals. Nutraceuticals are substances that have positive effects, proven by clinical testing, on normal physiological functions that maintain health in humans, thus preventing and treating diseases and enhancing longevity. There is a globally growing market for nutraceuticals sold as nutrients and supplements or in the form of enhanced “functional foods”. Natural bioactive compounds found in macrofungi are ideal for this market and are already being used for their properties.

Pollution Levels in Various Environmental Compartments
Population growth is another source of pollution in the environment. Heavy metal pollution wreaks havoc on soil and groundwater, especially in China. COVID-19 has pros and cons. The COVID-19 epidemic has reduced air pollution in China and caused a significant reduction in CO2 releases globally due to the lockdown but has a harmful effect on human health and the economy. Moreover, COVID-19 brings a huge amount of biomedical waste. COVID-19’s biomedical waste appears to be causing different health issues. On the other hand, it was discovered that recycling has become a new source of pollution in south China. Furthermore, heavy metal contamination is the most severe ecological effect. Likewise, every problem has a remedy to create new waste management and pollution monitoring policy. The construction of a modern recycling refinery is an important aspect of national waste disposal.

EDCs and Prostate Disease
Endocrine-disrupting chemicals (EDCs) belong to a heterogeneous class of environmental pollutants widely diffused in different aquatic and terrestrial habitats. This implies that humans and animals are continuously exposed to EDCs from different matrices and sources. Moreover, pollution derived from anthropic and industrial activities leads to combined exposure to substances with multiple mechanisms of action on the endocrine system and correlated cell and tissue targets. For this reason, specific organs, such as the prostate gland, which physiologically are under the control of hormones like androgens and estrogens, are particularly sensitive to EDC stimulation. It is now well known that an imbalance in hormonal regulation can cause the onset of various prostate diseases, from benign prostate hyperplasia to prostate cancer.

Petroleum Coke on Hg0 Removal
As the solid waste by-product from the delayed coking process, high-sulfur petroleum coke (HSPC), which is hardly used for green utilization, becomes a promising raw material for Hg0 removal from coal-fired flue gas. The effects of the physical–chemical evolution of HSPC on Hg0 removal are discussed. The improved micropores created by pyrolysis and KOH activation could lead to over 50% of Hg0 removal efficiency with the loss of inherent sulfur. Additional S-containing and Br-containing additives are usually introduced to enhance active surface functional groups for Hg0 oxidation, where the main product are HgS, HgBr, and HgBr2. The chemical–mechanical activation method can make additives well loaded on the surface for Hg0 removal.
