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.

Repeated Plant Debris Reutilization as Organic Amendment
Greenhouse agriculture typically generates large amounts of waste with plant residue (agricultural biomass) being the most abundant. This residue is generated on a seasonal basis, which complicates the external management of the material. Recently, the European Union (EU) has been implementing a policy based on sustainability through the circular economy that seeks to minimize waste generation. The effect of reusing 3.5 kg·m-2 tomato plants from the previous season as the only fertilizer versus no fertilization and inorganic fertilization in 215-day tomato cycles after transplanting was studied in this trial. The study was carried out during three seasons in greenhouse agriculture in Almeria (Spain) with the repeated use of the solarization technique. The plant debris had similar production results during two of the three seasons and fruit quality parameters were similar to inorganic fertilization. In addition, some physicochemical variables improved and the biological depressive effect of solarization was mitigated. The results suggest that the reuse of the tomato plant debris as the only fertilizer could be an alternative to conventional fertilization under the conditions tested.

Reproductive Potential in Primula veris L. (Primulaceae)
Primula veris (Primulaceae) is a valuable medicinal plant. P. veris is a Euro-Siberian Temperate element distributed throughout most of temperate Europe and Western Asia. As with most species of the genus Primula, it is entomophilous with a great affinity between its flowers. Insect pollinators belong to Hymenoptera (mainly bumblebees and bees), Lepidoptera and Diptera.

Circular Carbon Economy (CCE)
The circular carbon economy (CCE) system achieves a balance by closing the carbon circle, capturing CO2emissions, and using them economically after their initial linear use. This approach differs in that it does not focus solely on reducing or avoiding the increase in the amounts of carbon. The steady increase in carbon dioxide levels requires increased effort to mitigate their impact.

Roadkills for Monitor Raccoon Dog Populations
The raccoon dog (Nyctereutes procyonoides) is a highly invasive species, therefore knowledge regarding the population size, trends and spatial distribution is important for species assessment and for the planning of control measures. And the raccoon dog (Nyctereutes procyonoides) is one of the most frequently killed species on Lithuanian roads.

Skeletal Fluorosis
Fluorine is widely dispersed in nature and has multiple physiological functions. Although it is usually regarded as an essential trace element for humans, this view is not held universally. Moreover, chronic fluorosis, mainly characterized by skeletal fluorosis, can be induced by long-term excessive fluoride consumption. High concentrations of fluoride in the environment and drinking water are major causes, and patients with skeletal fluorosis mainly present with symptoms of osteosclerosis, osteochondrosis, osteoporosis, and degenerative changes in joint cartilage. Etiologies for skeletal fluorosis have been established, but the specific pathogenesis is inconclusive. Currently, active osteogenesis and accelerated bone turnover are considered critical processes in the progression of skeletal fluorosis. In recent years, researchers have conducted extensive studies in fields of signaling pathways (Wnt/β-catenin, Notch, PI3K/Akt/mTOR, Hedgehog, parathyroid hone, and insulin signaling pathways), stress pathways (oxidative stress and endoplasmic reticulum stress pathways), epigenetics (DNA methylation and non-coding RNAs), and their inter-regulation involved in the pathogenesis of skeletal fluorosis.

Environmental Applications of Chitin
Chitin’s environmentally friendly nature has been well documented, further allowing scientists to develop novel techniques utilizing chitin in the environmental sector. Chitin has a very high surface area due to the size of the biopolymer, which is applicable as a pollutant absorber and is used for other modifications that can be made into nanocomposites, best suited for environmental applications for soil and water pollutants.
