The purpose of this study was to characterize the concentrations of lead (Pb), cadmium (Cd), manganese (Mn), and Fe (Fe) in drinking water sources in primary schools in Sindh Province, Pakistan and to quantify potential health risks among those school children. We conducted a representative, cross-sectional study among 425 primary schools in Sindh province of Pakistan. We used risk assessment models to estimate the metal index, pollution index, lifetime cancer risk, and hazard quotient index. Across the 425 sampled schools, the levels of heavy metals in the drinking water often exceeded the WHO permissible limits (67% of schools exceeded Pb limit, 17% for Cd, 15% for Fe). The average incremental lifetime cancer risk (ILCR) for Pb exceeded tolerable limits in all of the districts under study. The findings, particularly for Pb, are of concern, as Pb may negatively influence children's growth, development, school performance, and long-term health.

TRACE ORGANIC COMPOUNDS AND PHOTOSENSITIZING ACTIVITY IN SALVADORAN SURFACE AND TAP WATER SOURCES: A FIRST LOOK.

Despite their potential risks to human health and the environment at ng/L to μg/L concentrations, there has been relatively little effort to measure trace organic compounds (TOrCs) in surface waters of Central America. The concentrations of eighteen TOrCs detected at eleven surface water sites in the Lempa River basin of El Salvador and four sources of drinking water for the cities of San Salvador, Antiguo Cuscatlán, Soyapango, and Santa Tecla are reported here. All samples were analyzed via liquid chromatography with tandem mass spectrometry (LC-MS/MS).

Fluorine is a strong oxidizing element and excessive intake can have harmful effects, particularly on the body's calcified tissues. Recent studies have demonstrated a link between miRNA and fluorosis. This study aimed to evaluate the time-dose-effect relationship of miR-200c-3p in plasma, urine and cartilage of rats with drinking water fluorosis, and to explore its potential as a biomarker.

The simultaneous detection and removal of Ag from drinking water was crucial for preventing human health, while it was also extremely challenging due to bifunctional materials that combine both Ag adsorption and detection functions rarely being explored. In this study, a benzotrithiophene-based covalent organic framework (TAPA-BTT) was synthesized and applied to detect and remove Ag. TAPA-BTT exhibited high crystallinity, a large specific surface area, and good thermal stability.

The continued development in agriculture, the rapid growth of industrialization, and last but not least, the increase in the global population adversely affects the environment. The availability of drinking water decreases every year with the rise in water pollution, which is the consequence of the failure of conventional approaches to the water treatment process. This review will provide a comprehensive and detailed analysis of the electrochemical water treatment processes, as these techniques have several benefits over conventional methods, such as being cost-effective, easily applicable, selective, and broad applicability.

Microplastics (MPs) and Di-(2-ethylhexyl) phthalate (DEHP) as emerging contaminants, have caused increasing concern due to their co-exposure risks and toxicities to humans. Lactic acid bacteria have been demonstrated to play a significant role in the mitigation of organismal damage. Probiotic intervention is widely recognized as a safe and healthy therapeutic strategy for targeting the mitigation of organic damage.
