Summary

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.

Barriers to Industrial Symbiosis
Industrial symbiosis (IS) can contribute to achieving a win-win situation between industry and environment for local and regional circular economies. Many authors have recognized that a variety of barriers can hinder the implementation of industrial symbiosis (IS). It is imperative to understand and prioritize the barriers which will provide guidance for the realization of IS projects and assist practitioners and stakeholders with more effective implementation. This, in turn, will contribute to development of circular economies.

Ecological Succession Theory
In addition to states of space that are supposedly to be aspired to or maintained, which are often the subject of heated, acrimonious debates, there are temporary states of equilibrium in time that mirror the overarching cycle of life, have been the subject of research for a very long time, and are well documented and conceptually understood: namely, ecological succession. The knowledge and understanding of succession is irreplaceable to have a chance today to ground and resolve such mentioned debates about multiple claims and uses of spaces nowadays. For example, a main challenge of the current time is that large areas of land are needed for renewable energy production, and production sites should be designed to include biodiversity preservation. Decision-makers need guidance for reasonable coexistence. Succession theory can indeed provide substantial background and guidance.

Gynogenesis in Agricultural Crops
Gynogenesis is a viable methodology with promising results in recalcitrant species for the generation of doubled haploids, which uses unpollinated female gametophytes. This technique has been successful in loquat (Eriobotrya japonica (Thumb) Lindl.), citrus (Citrus grandis (L.) Osbeck), spinach (Spinacia oleracea L.), cucurbits, red beet (Beta vulgaris L.) and Gentiana ssp. crops, where it is feasible to apply this technique in breeding.

Arsenic Exposure via Contaminated Water and Food Sources
Arsenic poisoning constitutes a major threat to humans, causing various health problems. The presence of arsenic in ecosystems can originate from several natural or anthropogenic activities. Arsenic can be then gradually accumulated in different food sources, such as vegetables, rice and other crops, but also in seafood, etc., and in water sources (mainly in groundwater, but also to a lesser extent in surface water), potentially used as drinking-water supplies, provoking their contamination and therefore potential health problems to the consumers.

Port-Related Shipping Gas Emissions
The global increase in shipping activity has contributed to the degradation of air quality, which particularly affects traffic-dense port areas. Due to the environmental and public health impacts of air quality in port cities, a number of inventories using varying methodologies have been conducted over the past two decades to manage gas emissions in specific areas.

Allelopathic Potential of Lemna minor L.
Allelopathy is an interaction that releases allelochemicals (chemicals that act allelopathically) from plants into the environment that can limit or stimulate the development, reproduction, and survival of target organisms and alter the environment. Lemna minor L. contains chemicals that are allelopathic, such as phenolic acids. Chemical compounds contained in L. minor may have a significant impact on the development and the rate of multiplication and lead to stronger competition, which may enhance the allelopathic potential. Allelopathic potential may exist between L. minor and C. glomerata (L) Kütz. because they occupy a similar space in the aquatic ecosystem, have a similar preference for the amount of light, and compete for similar habitat resources. L. minor and C. glomerata can form dense populations on the water surface. Allelopathy can be seen as a wish to dominate one of the plants in the aquatic ecosystem. By creating a place for the development of extensive mats, an interspecific interaction is created and one of the species achieves competitive success. It is most effective as a result of the release of chemicals by macrophytes into the aquatic environment. Therefore, allelopathy plays a significant role in the formation, stabilization, and dynamics of the structure of plant communities.

Management Practices and SOC Dynamics during Rural–Urban Transformations
Rapid urbanization and agricultural intensification are currently impacting the soils of many tropical countries. Bangalore is a growing megacity experiencing both issues and their derived ecological and socio-economic effects. Fertilization increases SOC concentrations, especially when mineral fertilizer is combined with additional farmyard manure. Single mineral fertilizer and a combination of mineral fertilizer and farmyard manure are commonly applied in Bangalore. Conservation practices, such as reduced tillage and mulching, are applied by 48% and 16% of households, respectively. Farm and household characteristics, including market integration, are the most important determinants of management decisions that affect SOC.

Role of PM2.5 in Viral Infections
Several epidemiologic and toxicological studies have commonly viewed ambient fine particulate matter (PM2.5), defined as particles having an aerodynamic diameter of less than 2.5 µm, as a significant potential danger to human health. PM2.5 is mostly absorbed through the respiratory system, where it can infiltrate the lung alveoli and reach the bloodstream. In the respiratory system, reactive oxygen or nitrogen species (ROS, RNS) and oxidative stress stimulate the generation of mediators of pulmonary inflammation and begin or promote numerous illnesses.

Environmental Taxes
The environmental tax is designed to motivate companies and citizens to seek solutions that limit the negative aspects of running a business. Environmental taxes or ecological taxes are defined in various ways. They can be defined as a non-returnable payment to the state that is levied on the object of taxation. The functions to be fulfilled by the environmental tax can be divided into three categories, i.e., redistributive, incentive, and fiscal. Redistribution consists of the division of the obtained funds and their allocation, for example, to environmental funds. The fiscal function allows the accumulation of funds for the state budget.
