“…In Pakistan, water is supplied to people through two sources of water i.e., the surface drinking water supply is coming from the ground and surface water from rivers or canals. But the water quality is getting worse due to impurities coming from the industrial and agricultural waste (Deeba et al, 2019). Due to such a situation, people are preferring bottled water for drinking purposes.…”

Water resources sustainability and conservation are crucial to controlling water scarcity in the world. This research examines the gendered perception of households in 12 Katchi Abadis of Lahore to conserve water by focusing on their habits, attitude, intention, norms, and behaviour. This is a qualitative research design with in-depth interviews as a method. Respondents were selected by adopting the purposive sampling technique. The debate revolves around the question: which one among men and women in the slum, will be responsible to show proper water managing intentions and behaviour? Is there any difference among men and women in slums on water-saving attitude, norms, intention, and behaviour? 24 face-to-face semi-structured in-depth interviews were conducted with youths, adults, and elderly males and females. Thematic analysis was used for analysis. It was revealed that people in homes acknowledged the worth of water, but poverty, unemployment, and government unresponsive behaviour caused hindrance to efforts to save water. There is a long list of hurdles that retards the process to conserve water. This research recommended conducting studies on the practices of water in households with actual measurements, not only for self-reported data, but it should also assess, and observe actions of individuals towards the environment.

Water samples were collected in spring once a month on arbitrarily selected dates: 23.03., 17.04., 18.05, and 25.06 in the year 2008; and 16.03., 13.04., 11.05, and 15.06 in the year 2013. Temperature [24] and the pH of water [25] were determined at the place of sample collection.…”

“…The rapid stride in industrialization is a major concern and at present is a severe threat to the survival of living organisms, jeopardizing the ecological balance [15]. In the world literature, results for pollution of various types of water (surface waters, groundwater) in various areas are comparable [16][17][18][19].…”

During spring 2008 and 2013, the concentrations of nitrogen substances (NO 3-, NO 2 and NH 4 +) were investigated against the background of changes in other selected physical and chemical water quality indices in the surface waters of Lake Warnowo located in Wolin National Park on Volin Island. It was found that the investigated waters were additionally contaminated by nitrogen compounds. This is illustrated by increased values of NO 3-, NO 2 and NH 4 + concentrations of the investigated waters in 2013 to max. values 0,28 (N-NO 3 /dm 3), 0,103 (N-NO 2 /dm 3) and 0,34 (N-NH 4 /dm 3), causing water quality deterioration in the lake by one class of quality compared to 2008 (where the max. values amounted to 0,39 (N-NO 3 /dm 3), 0,016 (N-NO 2 /dm 3) and 0,13 (N-NH 4 /dm 3), which led to accelerated water eutrophication in the lake in 2008-2013. This paper performs one of the chemometric techniques-principal component analysis (PCA)-used to classify water quality indices.

“…The PCA of related material is given in Table 3 and results of present investigation revealed that La 1−y Gd y Ni 1−x Co x O 3 is highly efficient for the degradation of dyes under visible light irradiation, which is regarded as economical process in comparison to materials active under UV light irradiation. 6,7,22,23,45,46 The water contamination with dyes and other pollutants is one of leading environmental issue 13,[47][48][49][50] and there is a need to treat wastewater before being discharged into the water bodies using efficient and eco-benign techniques and La 1 −y Gd y Ni 1−x Co x O 3 proved to be highly efficient in this regard vs methods employed for the treatment of wastewater. [14][15][16][17][18][51][52][53][54][55][56][57] Figure 17A-C represents the RhB dye degradation kinetics.…”

Gadolinium-and Cobalt-doped La 1−y Gd y Ni 1−x Co x O 3 perovskite nanoparticles were synthesized using facile micro-emulsion route to investigate the doping effect of Gadolinium and Cobalt on structural, morphological, dielectric, electrochemical, and photocatalytic activities of LaNiO 3 . The characterization of as-synthesized material was performed using X-ray diffraction, scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), UV-visible, and Raman scattering techniques. Structural analysis of Gd-and Co-doped LaNiO 3 shows single-phase distorted rhombohedral structure with successful doping of Gd and Co and particles size was estimated in the range of 25-45 nm with heterogeneous morphology. The CV (cyclic voltammetry), EIS (electrochemical impedance spectroscopy), and current-voltage (I-V) analysis revealed that the Gd and Co doping enhanced the electrical properties of LaNiO 3 . CV and EIS of Gd-and Co-doped composition (x, y = 0.50) electrode shows higher specific capacitance (148 Fg −1 ) vs undoped LaNiO 3 (95 Fg −1 ). The (I-V) results revealed that conductivity was improved by Gd and Co doping, the conductivity values for composition (x, y = 0.50) were 3.01 × 10 4 S/m vs 2.08 × 10 −3 S/m for undoped LaNiO 3 . Frequency dependent dielectric properties of La 1−y Gd y Ni 1 −x Co x O 3 synthesized material show decreasing trend in dielectric constant, dielectric loss, tangent loss by increase in frequency and AC conductivity was increased by the doping of Gd and Co in LaNiO 3 . Resistivity measurements show a decrease in resistivity by Gd and Co doping. Ferroelectric loop of the Gd-and Co-doped material shows an increased ferroelectric nature than LaNiO 3 . Photoluminescence spectra show an excitation peaks in visible region, which decreases as the dopant content (x, y) was increased. The band gap energy (E g ) was estimated using Tauc's plot and it was observed that by increasing the dopant (x,y) contents, the band gap was decreased (3.25-2.53 eV). Photocatalytic activity of LaNiO 3 and La 1−y Gd y Ni 1−x Co x O 3 was tested for Rhodamine B (RhB) dye under solar light irradiation. Result shows that the doped material was significantly more photocatalytically active than
