In order to assist drinking water utilities with identifying the possible sources and causes of taste-and-odor conditions associated with materials used in distribution systems, we evaluated information from case studies and a database from the National Sanitation Foundation (NSF), International. This database identified chemicals that had leached from drinking water system components during testing of materials under ANSI/NSF Standard 61, which provides information to water utilities on potential taste-and-odor and health concerns from the use of new materials. The data were arranged to provide a process for locating the potential source of a taste-and-odor event. After a sensory analysis is conducted on the drinking water samples, the descriptor can be matched with categories on the "Drinking Water Taste and Odor Wheel 2000" in order to suggest the candidate material.

Introduction: Cholera outbreaks remain persistent in the WHO African region, with an increased trend in recent years. This study analyses actual drivers of cholera including correlations with water, sanitation, and hygiene (WASH) indicators, and climate change trends.
Methods: This was a cross-sectional descriptive and analytic study.

Per- and polyfluoroalkyl substances (PFAS), also known as "forever chemicals" because of their persistence in the environment, have been used in many commercial applications since the 1940s. Of late, the detection of PFAS in drinking water throughout the United States has raised public and scientific concerns. To understand PFAS exposure trends in the general U.

Alcoholic liver disease (ALD) is a commonly known liver disease mediated by prolonged alcohol consumption. Aescin is a triterpene saponin that can manage several conditions, including brain trauma, arthritis, venous congestion, stroke, and thrombophlebitis. Even so, studies illustrating the aescin role in ALD are scarce.

Salmonella is an enteric pathogenic bacterium in mammals that thrives in sewage, soil, and aquatic environments because of its wide ecological adaptability. The spread of Salmonella infection is associated with a lack of clean water, poor hygiene, and poor sanitation in developing countries. However, the input of Salmonella-contaminated surface water and groundwater in the environmental dissemination of antimicrobial-resistant Salmonella is obscure outside developed countries.

Background: Millions worldwide are exposed to elevated levels of arsenic that significantly increase their risk of developing atherosclerosis, a pathology primarily driven by immune cells. While the impact of arsenic on immune cell populations in atherosclerotic plaques has been broadly characterized, cellular heterogeneity is a substantial barrier to in-depth examinations of the cellular dynamics for varying immune cell populations.
Objectives: This study aimed to conduct single-cell multi-omics profiling of atherosclerotic plaques in apolipoprotein E knockout () mice to elucidate transcriptomic and epigenetic changes in immune cells induced by arsenic exposure.
