Environmental Sciences

Environmental science emerged from the fields of natural history and medicine during the Enlightenment. Today, it provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems. Environmental studies are incorporating more of the social sciences in order to understand human relationships, perceptions and policies towards the environment. This entry collection features information about design and technology for improving environmental quality in every aspect.

Definition: Globally, agricultural soils are being evaluated for their role in climate change regulation as a potential sink for atmospheric carbon dioxide (CO2) through sequestration of organic carbon as soil organic matter. Scientists and policy analysts increasingly seek to develop programs and policies which recognize the importance of mitigation of climate change and insurance of ecological sustainability when managing agricultural soils.

Definition: Transformative agroecology has been recognized as a stepping stone to achieving several Sustainable Development Goals (SDGs), due to its great potential to build climate change-resilient farming systems while enhancing ecosystem services and reducing biodiversity loss. Understanding the agroecological elements that underlie the sustainability of an agroecosystem is an urgent matter, serving as the foundation for designing a truly transformative agroecosystem.

Definition: Mosses are one of the best bioindicators in the assessment of atmospheric aerosol pollution by heavy metals. Studies using mosses allow both short- and long-term air quality monitoring. The increasing contamination of the environment (including air) is causing a search for new, cheap and effective methods of monitoring its condition. Once such method is the use of mosses in active biomonitoring. The aim of the entry was to assess the atmospheric aerosol pollution with selected heavy metals (Ni, Cu, Zn, Cd, Hg and Pb) from the smoke of fireworks used during New Year’s Eve in the years 2019/2020 and 2020/2021.

Definition: The GMOS (Global Mercury Observation System) project has the overall goal to develop a coordinated observing system to monitor mercury on a global scale. We present the long-term (2011 – 2020) air mercury monitoring data obtained at the Listvyanka station located at a shore of Lake Baikal, Siberia. The long-term monitoring shows obvious seasonal variation of the background mercury concentration in air, which increases in the cold and decreases in the warm season. The short-term anomalies are associated with the wind carrying the air from the industrial areas where several big coal-fired power plants are located. A positive correlation between the mercury, SO2 and NO2 concentrations is observed both in the short-term variations and in the monthly average concentrations. The analysis of forward and backward trajectories obtained with the HYSPLIT model demonstrates revealing of the mercury emissions sources. During the cruise of 2018, the continuous air mercury survey over Lake Baikal covered 1800 km. The average mercury concentration over Baikal is notably less in comparison with the average value obtained at the onshore Listvyanka station during the same days of cruise. That can lead to the conclusion that Baikal is a significant sink of the atmospheric mercury.

Definition: The accurate forecast of air temperature plays an important role in water resources management, land–atmosphere interaction, and agriculture. However, it is difficult to accurately predict air temperature due to its non-linear and chaotic nature. Several deep learning techniques have been proposed over the last few decades to forecast air temperature.

Definition: Air pollution has recently become a subject of increasing concern in many parts of the world. The World Health Organization (WHO) estimated that nearly 4.2 million early deaths are due to exposure to fine particles in polluted air, which causes multiple respiratory diseases. As a natural product, algae can be an alternative treatment due to potential biofunctional properties and advantages.

Definition: Anabaenopeptins (APs) are structurally diverse peptides widely distributed in distinct ecosystems among cyanobacteria. Some structural features of these molecules are shared with other cyanotoxins, such as the presence of modified residues, exocyclic amino acids, circular structure, and amino acids in D-configuration. However, among the cyanopeptides, the ureido linkage is exclusively found in APs. Thus, these cyclic peptides demonstrate toxicity and structural diversity which will be explored in this topic, including biotechnological and ecological relevance, and their distribution.
