Processes Responsible for Nitrate Pollution in Water
Nitrate (NO3−) pollution of surface and groundwater bodies is a global problem of increasing concern, which has stimulated significant research interest. Nitrogen is crucial for life as a macronutrient for living organisms on Earth, but the global nitrogen cycle has been seriously altered by intensification of human activities, leading to eutrophication and hypoxic conditions of aquatic ecosystems. Due to nitrogen overfertilization, intensive agricultural practices generate huge nitrate fluxes that inadvertently deteriorate water quality. Different industrial processes also contribute to NO3− pollution in the environment.

Soil Colour and Plant-Wax Markers
Most cases involving soil in criminal investigations in Brazil have focused on the chemical and mineralogical analyses of soil fractions without including the organic matter. The organic fraction contains plant-wax markers which may be useful to “fingerprint” forensic soils due to their chemical diversity, relative longevity and resistant nature.

Odors Abatement
Traditionally, odor abatement has been carried out using physical–chemical technologies such as chemical absorption (scrubbing) and adsorption. However, biological technologies for odor treatment such as biofilters or biotrickling filters have become more relevant in the last years for many reasons, such as their high odor removal performances and the low operational costs associated.

Reducing Inequalities within and among EU Countries
Reducing inequalities within and among countries is one of the main tenets of the sustainable development paradigm and has become an important pillar at the European Union level. By adopting the 2030 Agenda for Sustainable Development, EU countries have committed themselves to meeting targets against which progress in reducing inequalities can be measured. Through the present research, it can analyze and assess the extent to which EU countries will achieve the specific SDG 10 targets. Based on data published by Eurostat for the period 2010-2020, it can forecast the trends of the indicators until the year 2030, using a model based on AAA (Holt-Winters) version of the exponential smoothing (ETS), to assess the degree to which the assumed targets will be reached. For more detailed information, dynamic indices were used to analyze the dynamics of the progress achieved. The results showed that it is difficult to clearly distinguish one or more countries as part of a group of high or low performers in terms of the efforts made and the effects achieved in reducing inequalities. However, it can be mentioned that Poland as a good and very good performer on most of the indicators analyzed. At the opposite, Bulgaria and Greece, for which more attention and involvement is needed in adopting measures to correct the negative trends forecast.

De-Carbonization of Zhejiang Province by Nature
The increasing emission of CO2 causes global warming and ocean acidification, imposing damages on the global ecosystem. With the continuous development of industry, fossil CO2 emissions have increased rapidly, and global fossil CO2 emissions have reached 36.4 Gt yr−1 in 2021. In response to the increasing global warming, climate goals, i.e., “zero carbon” and “carbon neutral”, have been proposed by more than 130 countries in the world while 66 of them have reached a consensus on the net-zero target.

Biodiesel Production from Fish Waste
Biofuels including biodiesel, bioethanol, biobutanol, biohydrogen, etc., are generated from different biological sources, and their waste which stands as the best alternative in the present scenario. Specifically, the utilization of biological wastes as raw materials for the production of biofuels is considered as best waste management practice. To date, most of the biodiesel production research has been carried out with plant, algal, and microbial samples, or their waste. It is a well-known fact that diesel can also be produced from specific oily fish and their waste using different methods. In addition, fish waste constitutes a major quantity compared to other food waste which is a serious concern. Furthermore, the disposal of fish waste shows an impact on both the environment and the economy. Hence, the development of protocols for the efficient production of biodiesel from fish waste is the ultimate goal.

A General Description of Karst Types
This study includes a general description of the Earth’s karst types based on literary data and field observations. An improved classification of karst types distinguishes the main group, group, and subgroup; and, a division of karst types involves a main karst type, karst type, subtype, variety, and non-individual karst type. The relation between karst type and karst area is described. The role of various characteristics of karsts in the development of primary, secondary, and tertiary karst types is analyzed. Their structure is studied, which includes a geomorphic agent, process, feature, feature assemblage, karst system and the characteristics of the bearing karst area. Dominant, tributary, and accessory features are distinguished. The conditions of the stability and the development of types are studied, transformation ways are classified, and the effect of climate on types is described.

Climate Change Denial: Heads in the Sand
Climate Change Denial: Heads in the Sand is a non-fiction book about climate change denial, coauthored by Haydn Washington and John Cook, with a foreword by Naomi Oreskes. Washington had a background in environmental science prior to authoring the work, and Cook was educated in physics and founded the website Skeptical Science which compiles peer-reviewed evidence of global warming. The book was first published in hardcover and paperback formats in 2011 by Earthscan, a division of Routledge. The book presents an in-depth analysis and refutation of climate change denial, going over several arguments point-by-point and disproving them with peer-reviewed evidence from the scientific consensus for climate change. The authors assert that those denying climate change engage in tactics including cherry picking data purported to support their specific viewpoints, and attacking the integrity of climate scientists. They use social science theory to examine the phenomenon of climate change denial in the wider public, and call this phenomenon a form of pathology. The book traces financial support for climate change denial to the fossil fuel industry, asserting these companies have attempted to influence public opinion on the matter. Washington and Cook write that politicians have a tendency to use weasel words as part of a propaganda tactic through use of spin, as a way to deflect public interest away from climate change and remain passive on the issue. The authors conclude that if the public ceased engaging in denial, the problem of climate change could be realistically addressed. For his research on the book, and efforts in communicating the essence of climate change science to the general public, John Cook won the 2011 Australian Museum Eureka Prize for Advancement of Climate Change Knowledge. Climate Change Denial received a positive reception in reviews from publications including: The Ecologist, ECOS magazine, academic journal Natures Sciences Sociétés, the journal Education published by the New South Wales Teachers Federation,. An article in The New American was critical, describing the labels of "deniers" and "denialists" as cruel and forms of character assassination.

Hybrid Artificial Intelligence in Groundwater
As one of the world’s most valuable and vital water sources, groundwater is integral to many facets of human life, including food production, economic growth, and safe drinking water. Developing precise soft computing methods for groundwater management, which includes quality and quantity, is crucial for improving water resources planning and management. Significant progress has been made in groundwater management using hybrid machine learning (ML) models as artificial intelligence (AI).

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.
