“…It was tested with good results by the authors of [49]; however, in many cases, studies on water harvesting methods were only concentrated on the energy issue, and on the possibility to enhance the absorbent capacity of particular materials. For example, the authors of [43] highlighted the impossibility of conducting a systematic analysis of water quality when radiative cooling and vapor sorption techniques are employed due to a lack of relevant studies, while the authors of [50] stated a similar absence in the AWG field.…”

“…When the water source is the external air, previously mechanically filtered, the main chemical pollution, even under heavily air polluted environments, seems to only be composed of nitrites and ammonia [50]. Ammonia levels frequently exceed the limit of 0.5 mg/L and tend to increase when the relative humidity decreases [51].…”

“…Ammonia levels frequently exceed the limit of 0.5 mg/L and tend to increase when the relative humidity decreases [51]. Mechanical filtration can be found in active systems, while, normally, it is absent in the passive ones as it requires energy; • Passive systems, that do not comprise any air filtration nor anti-intrusion protections, are affected by macroscopic pollutants and pollution vectors, such as dust particles, animals, insects, and so on [52], and the gathered water is more polluted in comparison to that collected by means of active systems (that are equipped with filters and protections) [50];…”

This research investigated the suitability of air-to-water generator (AWG) technology to address one of the main concerns in green hydrogen production, namely water supply. This study specifically addresses water quality and energy sustainability issues, which are crucial research questions when AWG technology is intended for electrolysis. To this scope, a reasoned summary of the main findings related to atmospheric water quality has been provided. Moreover, several experimental chemical analyses specifically focused on meeting electrolysis process requirements, on water produced using a real integrated AWG system equipped with certified materials for food contact, were discussed. To assess the energy sustainability of AWGs in green hydrogen production, a case study was presented regarding an electrolyzer plant intended to serve as energy storage for a 2 MW photovoltaic field on Iriomote Island. The integrated AWG, used for the water quality analyses, was studied in order to determine its performance in the specific island climate conditions. The production exceeded the needs of the electrolyzer; thus, the overproduction was considered for the panels cleaning due to the high purity of the water. Due to such an operation, the efficiency recovery was more than enough to cover the AWG energy consumption. This paper, on the basis of the quantity results, provides the first answers to the said research questions concerning water quality and energy consumption, establishing the potential of AWG as a viable solution for addressing water scarcity, and enhancing the sustainability of electrolysis processes in green hydrogen production.

“…Furthermore, the growing demand for electricity has increased energy consumption by 50% [27][28][29]. A rapid rise in the production of domestic and industrial products is causing developing countries to generate waste, extract resources, consume fossil fuels, and expand their ecological footprints [30][31][32]. Overuse of ecosystem services, however, can also have negative consequences; for instance, it can lead to global warming, exacerbating the physical effects of climate change.…”

This study aims to fill a crucial gap in current research by examining the multifaceted relationships between energy depletion, technical cooperation grants, industrialization, and environmental degradation. By focusing on Pakistan, a country emblematic of many developing nations facing rapid industrialization and resource constraints, this research offers valuable insights with broad applicability. The significance of this study lies in its innovative approach of utilizing load capacity factor as a novel proxy for environmental sustainability, moving beyond traditional metrics like CO2 emissions and ecological footprints. The study analyzes time series data from 1970 to 2022 using advanced econometric techniques, particularly the dynamic autoregressive distributed lag (ARDL) model. The findings reveal a nuanced picture of the impact of energy depletion, technical cooperation grants, and industrialization on environmental degradation. Energy depletion and industrialization are found to exert a significant and adverse influence on environmental quality, exacerbating degradation over time. Conversely, technical cooperation grants emerge as a mitigating factor, demonstrating a positive association with environmental sustainability. Moreover, the study conducts a sensitivity analysis by comparing the results obtained using the load capacity factor with those derived from ecological footprints. This comparative analysis offers robust insights into the dynamics of environmental degradation, enriching the understanding of the complex interplay between economic activities and environmental outcomes. Further, policies are discussed for theory and practice.

“…The world's population is growing, industrial production is increasing rapidly, and as a result, the demand for fresh water is increasing significantly. One of the global challenges related to fresh water is the contamination of water bodies with HMs, which do not degrade once they enter the aquatic environment and are toxic to many life forms [1][2][3][4].…”

Fresh water scarcity is considered a significant component, and potentially one of the most critical, of global climate change. With the rapid development of industry, there is an increasing risk of freshwater contamination by heavy metals (HMs). The danger of HM pollution is also attributed to their accumulation, which can subsequently become a source of secondary pollution in aquatic environments. In the Lake Gusinoe basin, located in Russia, concentrations of HMs were measured in both water and bottom sediments within the lake area, as well as in inflowing and outflowing watercourses. Ecological risk indices were also calculated for the Gusinoe basin. Our results showed that the average concentrations of Fe, Zn, Cr, Ni, Cd, and Pb in the water did not exceed the maximum allowable concentrations (MACs) set by Russian national standards and WHO standards, while the concentrations of Mn and Cu exceeded the corresponding MACs during winter, spring, and autumn possibly due to decomposition of aquatic vegetation and influx from groundwater sources. The average concentrations of the investigated HMs in the BSs did not exceed the background values. The water hazard index indicated a low risk for all samples in the lake water area. For all BS samples, the geoaccumulation index (Igeo) and the Pollution Load Index (PLI) indicated low pollution levels, while the values of the Enrichment Factor (EF) and the Contamination Factor (CF) indicated moderate pollution in the central part of the lake. The Ecological Risk Factor (Er) for Cu in BSs at points near major settlements and in the Tel River indicated moderate pollution. The Potential Ecological Risk Index (RI) in all investigated BS samples indicated a low risk of contamination.
