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.

The Early Days of Personal Solar Ultraviolet Dosimetry
In the early 1970s, environmental conservationists were becoming concerned that a reduction in the thickness of the atmospheric ozone layer would lead to increased levels of ultraviolet (UV) radiation at ground level, resulting in higher population exposure to UV and subsequent harm, especially a rise in skin cancer. At the time, no measurements had been reported on the normal levels of solar UV radiation which populations received in their usual environment, so this lack of data, coupled with increasing concerns about the impact to human health, led to the development of simple devices that monitored personal UV exposure.

Adaptation to EUTR Requirements: Slovenia, Croatia and Serbia
Eight years after the European Union Timber Regulation (EUTR) came into force, its effectiveness is still unsatisfactory due to deficient and uneven implementation among member states.  In addition, some Western Balkan countries have poor legality monitoring systems, increasing the risk of trade in illegally harvested timber. Regardless of this, no recent work has analyzed the adaptation of national forest policies to the EUTR obligations. Author study aims to contribute to the understanding of EUTR implementation by analyzing the adaptation of policies of the Western Balkan countries (Slovenia, Croatia, and Serbia) to the EUTR. Qualitative content analysis was conducted on 22 policy documents from Slovenia, Croatia, and Serbia. Documents were coded using coding categories derived from EUTR. Our results point out that none of the analyzed countries have a policy to directly address illegal logging or prevention of illegal activities. As EU members, Slovenia and Croatia has implemented EUTR through laws. The Slovenian Forest Act addresses all EUTR obligations, while Croatian Law on EUTR Implementation does not directly address the obligation of legality. This obligation is addressed by the Law on Forests. As Serbia is not an EU member, it did not implement EUTR. Nevertheless, Serbian Law on Forests addresses all EUTR obligations, but has some discrepancies regarding Traceability obligation. With ongoing discourses on Green Deal policies and the increasing focus on “deforestation-free” commodities, stricter implementation might be expected of EUTR at EU level. Most countries would probably have to build capacities for EUTR implementation and become more transparent and responsible concerning information availability. To successfully implement EUTR, an increased number of checks as well as stricter fines will be needed.

Economic Indicators in Water Sector for Circular Economy
Protection and sustainable management of water was indicated as one of the strategic tasks in the process of transformation towards a circular economy (CE) in the European Union (EU), therefore, the water and wastewater sector plays an important role in this process.

ZnO Nanoparticles and Wheat and Maize
The zinc oxide nanoparticle (ZnO NP) is a commonly used metal oxide ENPs finding application as sunscreens and cosmetics, biosensors, and in solar cells, etc. Presently, many kinds of metal oxide NPs have been applied in agriculture, specifically in fertilization and plant protection in abiotic and biotic stress conditions.

Occupational Hearing Loss for Platinum Miners
This case study illustrates how research can be effectively, although not maliciously, obstructed by the strict protection of employee medical data. Clearly communicated company policies should be developed for the sharing of workers’ records in the mining industry to improve HCPs.

Iron Deficiency Anemia
Iron deficiency (ID) anemia is the foremost micronutrient deficiency worldwide, affecting around 40% of pregnant women and young children. ID during the prenatal and early postnatal periods has a pronounced effect on neurodevelopment, resulting in long-term effects such as cognitive impairment and increased risk for neuropsychiatric disorders. Treatment of ID has been complicated as it does not always resolve the long-lasting neurodevelopmental deficits. A better understanding of the underlying molecular mechanisms is needed in order to develop more effective treatments.

Aspergillus fumigatus
Aspergillus fumigatus is a ubiquitous saprophytic fungus. Inhalation of A. fumigatus spores can lead to Invasive Aspergillosis (IA) in people with weakened immune systems. The use of triazole antifungals with the demethylation inhibitor (DMI) mode of action to treat IA is being hampered by the spread of DMI-resistant “ARAf” (azole-resistant Aspergillus fumigatus) genotypes.

Multi-Element Imaging of the 1.4Ga Authigenic Siderite Crystal
The Al- and Fe-enriched zone in the core of siderite crystal might be an iron-bearing nucleus, and the formation of rim structure was related to the transition from a closed crystallization environment to a semi-closed growth environment. These results, combined with carbon isotope evidence from the siderites and surrounding shales, suggest that vigorous dissimilatory iron reduction that can provide Fe2+ and HCO3− to the pore water is a key factor to form the siderite-dominated Xiamaling IF.

Nano-(Q)SAR for Cytotoxicity Prediction of Engineered Nanomaterials
Nanomaterials and nanoparticles (NPs) possess unique physico-chemical properties (size, shape, chemical composition, physiochemical stability, crystal structure, surface area, surface energy, and surface roughness), which give them beneficial characteristics. Quantitative structure-activity relationship, or QSAR, is an area of molecular modeling that studies relationships between structure and activity using mathematical statistics and machine learning methods. QSAR is efficiently used to predict toxicity of chemical substances.

Probiotics for Freshwater Fish Farming
Probiotics for freshwater fish farming can be administered as single or multiple mixtures. The expected benefits of probiotics include disease prophylaxis, improved growth, and feed conversion parameters, such as the feed conversion rate (FCR) and specific growth rate (SGR).
