Article Synopsis
- Safe drinking water is a recognized human right, but data on safe drinking water access is missing for over half the world's population.
- In a study of 135 low- and middle-income countries, it was found that only one-third of people had access to safely managed drinking water services in 2020, with fecal contamination being a major issue affecting nearly 50% of the population.
- The findings highlight the need for improved monitoring of water access and show how global geospatial data can help identify areas in need and address data shortages.

Article Abstract
Safe drinking water access is a human right, but data on safely managed drinking water services (SMDWS) is lacking for more than half of the global population. We estimate SMDWS use in 135 low- and middle-income countries (LMICs) at subnational levels with a geospatial modeling approach, combining existing household survey data with available global geospatial datasets. We estimate that only one in three people used SMDWS in LMICs in 2020 and identified fecal contamination as the primary limiting factor affecting almost half of the population of LMICs. Our results are relevant for raising awareness about the challenges and limitations of current global monitoring approaches and demonstrating how globally available geospatial data can be leveraged to fill data gaps and identify priority areas in LMICs.

Unlabelled: Ecological succession is vital for forecasting ecosystem responses to environmental changes and their future states. Zooplankton, a primary natural food source in aquaculture, plays a crucial role in maintaining ecosystem function. Thus, understanding how zooplankton communities respond to environmental changes is essential for economic and ecological outcomes.

Objectives: To investigate the therapeutic mechanism of 2,6-dimethoxy-1,4-benzoquinone (DMQ) for alleviating dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice.
Methods: Eighteen male C57BL/6J mice were equally randomized into control group, DSS group and DMQ treatment group. In DSS and DMQ groups, the mice were treated with DSS in drinking water to induce UC, and received intraperitoneal injections of sterile PBS or DMQ (20 mg/kg) during modeling.

Phosphorus is recognized as a major pollutant in municipal and domestic wastewater, but the effective removal of organic phosphorus (OP) using conventional wastewater treatment technologies is difficult. Herein, a novel visible light-enhanced Ti electrocoagulation (EC) technology was proposed for the removal of OP using 2-amino-ethyl phosphonic acid (AEP) as a model compound to elucidate the removal efficiency and mechanisms. The results showed that the irradiation under visible light (670 Lux) effectively enhanced the removal of AEP by Ti EC.

The aldehyde addition reaction is recognized as a key pathway in the formation of haloacetamides (HAMs) in drinking water. In particular, the reaction between monochloramine and chloroaldehydes has been reported to proceed rapidly. However, the measured concentrations of haloaldehydes (HALs) in chloraminated water are often much higher than those of HAMs.

Introduction: Epidemiological studies focusing on the association of exposure to perfluoroalkyl substances (PFAS) with cardiovascular disease (CVD) morbidity and mortality are limited, with inconsistent findings.
Objectives: This register-based study aimed to investigate the associations between exposure to PFAS and the risk of CVD morbidity and mortality in a Swedish population exposed to PFAS, dominated by perfluorohexane sulfonic acid (PFHxS) and perfluorooctane sulfonic acid (PFOS), through drinking water for decades.
Methods: The study included 46 553 individuals aged ≥30 who lived in Ronneby (1985-2013).
