    Abstract From the starting of the pandemic different transmission routes of the pathogen was brought into the spotlight by researchers from different disciplines. This matter in high-altitudes was more boosted as the main parameters were not exactly realized. In this review we are about to highlight the possibility of consuming contaminated water generated form solar water desalination/disinfection systems in highlands. Three systems including solar still, solar disinfection (which experimented by the authors in 2019 in high altitude) and humidification-dehumidification were consider in this context. Ascribe to the risks of pathogens transmission in solar desalination/disinfection systems where the water resources are heavily polluted in every corner of the world, highlighting the risk of consuming water in high-altitude where there are many other parameters associated with spread of pathogen is of great importance. As it was reported, reliability of solar desalination and solar water disinfections systems against contaminated water by the novel coronavirus remained on the question because the virus can be transmitted by vapor in solar stills due to tiny particle size (60-140 nm) and would not be killed by solar disinfections due to low-temperature of operation <40 °C while for HDH contamination of both water and air by sars-cov-2 could be a concern. Although the SARS-CoV-2 is not a waterborne pathogen, its capability to replicate in stomach and infection of gastrointestinal glandular suggested the potential of transmission

    Abstract In recent years the use of nanoparticles in solar desalination is an emerging approach for improving the performance of systems. Utilizing nanoparticles in black paint of solar stills employed by some researchers but the number of studies in this context is limited. In all previous studies researchers usually utilized a single type of nanoparticle. In the present study silver (Ag), gold (Au), and titanium dioxide (TiO₂) with 0.1 wt% of concentration were utilized in three double-slope solar stills. Performance of the systems from energetic, exergetic, economic, exergoeconomc, enviroeconomic, CO₂ reduction, and energy matrices are examined. Findings revealed that the thermal efficiency of Ag-based solar still is calculated by about 33.68% which shows an improvement around 7.6%, 20.7%, 38.2% compared to Au, TiO₂, and conventional system while overall exergy efficiency of Ag-based system with 2.34% is higher by about 7.3%, 32%, 70.5% in comparison with aforementioned systems respectively. The exergoeconomic results based on energy and exergy from highest to lowest were obtained by Ag, TiO₂, conventional, and Au-based solar stills. Moreover, the economic assessment showed that the lowest and highest cost of distilled water with 0.0065 $/l.m⁻² and 0.0289 $/l.m⁻² were produced by Ag-based and Au-based solar stills. The rate of CO₂ mitigation for the systems with Ag, Au, TiO₂, and conventional was calculated by about 10.82, 10.02, 8.87, 7.7 t/y respectively. The energy payback time (EPBT) for all systems was less than 3 years. It can be concluded that using silver nanoparticle regarding the amount of improvement and the cost, is the most effective particle while the gold nanoparticle due to its high cost is not appropriate for use in solar stills.
