“…It was interesting to note that the concentration of metal ion leaching after treatment processes was very low and within the acceptable range of WHO permitted drinking water parameters. 70 In the first cycle, the highest concentration of copper ion leaching was measured to be 0.466 and 0.28 mg L −1 after 1 h, using NCC and CC, respectively (Fig. 13).…”

“…It is estimated that about 10,000 different dyes are used industrially and 7 × 10 10 dyes are produced annually worldwide, from which 10-15% of the dyes are released into industrial wastewater, as only 2-50% of the dye combines with the fabric during the dyeing process [5]. Industrial wastewater, which contains a lot of pollutants with detrimental and carcinogenic effects, is left untreated and drains into surface water resources, such as rivers and seas [6]. Apart from the aesthetics of water looking colorful and undesirable due to dye contamination, light penetration is also reduced in the water, severely affecting the photosynthetic activities of aquatic flora, which Crystals 2022, 12, 1153 2 of 13 leads to disturbances in the food chain of aquatic organisms [7].…”

In this work, we report the engineering of sub 30 nm nanoparticles of copper oxide (CuO) and Zinc oxide (ZnO) and their nanocomposite, using a green method, to degrade an organic dye (methyl orange) that is responsible for water pollution. The plant extract of Eucalyptus globulus was used as a capping and stabilizing agent, as it is non-toxic, easy to use, and affordable. The percent purity and composition of the samples were found using Energy Dispersive Spectroscopy (EDS), which confirmed the formation of 75% CuO nanoparticles, 77.81% ZnO nanoparticles, and 77.34% ZnO/CuO nanocomposite in respective samples. Morphological analysis was achieved using Scanning Electron Microscopy (SEM). FTIR investigations revealed that the vibrations of CuO and ZnO nanoparticles and CuO/ZnO nanocomposite were observed at 568 cm−1, 617.9 cm−1, and 475 cm−1, respectively. The bandgap of the synthesized CuO and ZnO nanoparticles, and ZnO/CuO nanocomposite was analyzed using Diffuse Reflectance Spectroscopy (DRS), and found to be 3.36 eV, 1.83 eV, and 1.48 eV, respectively. Best photocatalytic activity confirmed that favorable conditions for the maximum degradation of methyl orange are at pH 12 and 0.02 g of the photocatalyst is required.

“…Additionally, the semi-arid district's geography is distinguished by rough and sloppy terrain due to its plateau position, which reduces the monsoonal recharge by raising the likelihood of runoff. In addition, a wide range of human activities substantially influences these districts' access to household water (Hayder et al, 2022). For instance, the district's water resources, which provide the majority of the water for domestic use, quickly dry up.…”

An increase in population and water demand, climate change, and changes in land-use patterns are severe problems in Pakistan. Water management in Pakistan has been a provincial matter after the 18th amendment. Each province in Pakistan measures the water on its own intention and indicators. The current study aims to map the water scarcity status through the water poverty index (WPI) using the Multiple Indiactor Cluster Survey (2018) at the semi-arid districts in Punjab, Pakistan. WPI was estimated by using the components named “Resources,” “Access”, “Capacity”, “Use”, and “Environment”. Each component score was calculated using ifferent indicators, assuming equal weights for all components. Layyah (57.6) and RajanPur (48.03) had the best and worst situations among all districts in 2018. The findings showed that the absence of physical water resources in these districts is not the only factor of domestic water shortage but environment and capacity also plays a significant role in achieving the domestic water need. Due to their socioeconomic ineptitude, lack of infrastructure, and restricted access to water, the region is experiencing severe to high levels of household water poverty. This study's results showed that WPI is an operative tool to measure water scarcity and could be used to make an important priority for water management.
