“…The safety and quality of drinking water resources are at stake because these pollutants have the ability to contaminate surface water and seep into groundwater sources. Inadequate management and elimination of industrial waste can result in enduring environmental deterioration and possible health risks for populations reliant on these water supplies 10 . An official survey conducted across 12 districts in Punjab indicated that around 79% of drinking water samples were contaminated, while 88% of drinking water in rural areas was contaminated due to sewage discharge, heavy metals, microorganisms, and industrial effluents 11 , 12 .…”

The aim of the present study was to assess the drinking water quality in the selected urban areas of Lahore and to comprehend the public health status by addressing the basic drinking water quality parameters. Total 50 tap water samples were collected from groundwater in the two selected areas of district Lahore i.e., Gulshan-e-Ravi (site 1) and Samanabad (site 2). Water samples were analyzed in the laboratory to elucidate physico-chemical parameters including pH, turbidity, temperature, total dissolved solids (TDS), electrical conductivity (EC), dissolved oxygen (DO), total hardness, magnesium hardness, and calcium hardness. These physico-chemical parameters were used to examine the Water Quality Index (WQI) and Synthetic Pollution Index (SPI) in order to characterize the water quality. Results of th selected physico-chemical parameters were compared with World Health Organization (WHO) guidelines to determine the quality of drinking water. A GIS-based approach was used for mapping water quality, WQI, and SPI. Results of the present study revealed that the average value of temperature, pH, and DO of both study sites were within the WHO guidelines of 23.5 °C, 7.7, and 6.9 mg/L, respectively. The TDS level of site 1 was 192.56 mg/L (within WHO guidelines) and whereas, in site 2 it was found 612.84 mg/L (higher than WHO guidelines), respectively. Calcium hardness of site 1 and site 2 was observed within the range from 25.04 to 65.732 mg/L but, magnesium hardness values were higher than WHO guidelines. The major reason for poor water quality is old, worn-out water supply pipelines and improper waste disposal in the selected areas. The average WQI was found as 59.66 for site 1 and 77.30 for site 2. Results showed that the quality of the water was classified as “poor” for site 1 and “very poor “ for site 2. There is a need to address the problem of poor water quality and also raise the public awareness about the quality of drinking water and its associated health impacts.

“…The water samples used in this study were obtained from four distinct boreholes within the Lekki phase 1 residential areas. Each of the samples was collected in a pre-cleaned polyethylene bottle with capacity of 1.5 liters [23]. These samples were identified as A, B, C, D as presented in Table 1.…”

The pervasive presence of fake news on social media platforms poses a significant threat to the credibility of information, the functioning of democracies, and the stability of societies. This paper presents a comprehensive analysis of the application of machine learning techniques in managing fake news on social media. We discuss the challenges and opportunities in employing machine learning for fake news detection and mitigation, review the state-of-the-art methods, and suggest future research directions. We also highlight ethical considerations and the importance of maintaining user privacy while combating fake news.

“…With the rapid economic development and ever-increasing population, the number of waste land lls was expanding rapidly in China. Because of the high concentration of organic matter, inorganic matter, heavy metal and other components in land ll leachate, groundwater pollution caused by leaking has become one of the global ecological environment problems (Podlasek et al, 2023;Asomaku SO, 2023;Liu et al, 2023;Du et al, 2022;Han et al, 2016). Most provinces in China have also reported pollution caused by the leakage?…”

Landfill leachate has great pollution risk to groundwater, which is of practical significance to study the characteristics of leachate leakage and surrounding groundwater pollution and its harm to human health. Taking a typical valley-type landfill in South China as the research object, this paper ascertained the leakage area based on geophysical methods and groundwater sampling. A total of 21 parameters such as pH, total hardness (TH), total mineralization (TM), permanganate index (CODMn), ammonium (NH3-N), nitrites (NO3-N), nitrates (NO2-N), sulphates (SO4−), chloride (Cl−), fluorides (F−), volatile phenols, cyanide, and heavy metals (HMs) in groundwater and some indicators in leachate were tested, and the water quality and health risks were evaluated by using the Nemerow pollution index (NPI) method and BCRA (Rish-based Corrective Action) model. The results indicate that the leakage areas are existing in the middle of the landfill site, the middle and the south of the anti-seepage dam with a depth about 15-22m and main pollutants of CODMn and NH3-N. The main pollutants of pH, NH3-N, Fe and Mn were ranged from 5.80 to 6.70, 0.06 to 0.74 mg/L, 0.002–2.763 mg/L, and 0.003–1.181 mg/L, their rates exceed the class Ⅲ standard at 28.57%, 28.57%, 4.29% and 14.29%, respectively. The Nemerow pollution index showed that the groundwaters at ZK01 and ZK04 were seriously polluted. Groundwater quality was affected by leachate and natural geological background. The total non-carcinogenic risk of groundwater was ranked as LS102 < LS101 < ZK02 < ZK01 < ZK03 < ZK05 < ZK04, with Cl− and Mn as the main non-carcinogenic pollutants in the landfill. This rank reveals the rule that the closer to the waste body, the higher the risk.
