Low-income countries are struggling with the health impacts of both surface and groundwater chemical contamination. Although impact biological contaminants on children's is acknowledged, long-term effects these emerging young children may be underestimated. To map existing evidence water contaminated chemicals (<5 years), we conducted a scoping review to select organize relevant literature. Of 98 studies in review, 24 revealed that hazard ratio arsenic, nitrates, cadmium, fluoride (all which World Health Organisation's list 10 public concern) was higher very than older age groups. Anthropogenic activities (textile manufacturing, waste disposal, intensified agriculture) leading contributors release used for drinking. Three major pathways contamination exposure were confirmed: maternal transmission during pregnancy breastfeeding, early school years. Children exhibited acute chronic disruptions their neurological, skeletal, reproductive, endocrine systems, as well cumulative carcinogenic risks, amongst other life-altering consequences. The lack research contaminants' low-income worrisome, increased use compound issues caused by problem "legacy chemicals." Precautionary principle should regulate operation industries producing robust manner. Evidence from producers exporters high-income sufficient warrant action, even without waiting direct harm observed countries. Literature recommends prioritising prevention over demand side treatment or finding alternative sources, especially water-scarce areas affected climate change.

The world is not on track to meet Sustainable Development Goal 6.1 provide universal access safely managed drinking water by 2030. Removal of priority microbial contaminants disinfection one aspect ensuring managed. Passive chlorination (also called in-line chlorination) represents approach disinfecting before or at the point collection (POC), without requiring daily user input electricity. In contrast manual household methods typically implemented use (POU), passive chlorinators can reduce burden for chlorine dosing and enable treatment scales ranging from communities small municipalities. this review, we synthesized evidence 27 evaluations (in 19 articles, 3 NGO reports, 5 theses) conducted across 16 countries in communities, schools, health care facilities, refugee camps. Of identified, majority (22/27) were solid tablet granular dosers, remaining devices liquid dosers. We identified following research priorities address existing barriers scaled deployment chlorinators: (i) strengthening local supply chains through decentralized production, (ii) validating context-specific business models financial sustainability, (iii) leveraging remote monitoring sensing tools monitor real-time levels potential system failures, (iv) designing handpump-compatible serve many reliant handpumps as a primary source. also propose set reporting indicators future studies facilitate standardized technical performance sustainability chlorinators. addition, discuss limitations chlorine-based recognize importance addressing chemical contamination supplies. deployed at-scale have elevate quality accessible available services "safely managed" requirements.

Addressing the global challenge of ensuring access to safe drinking water, especially in developing countries, demands cost-effective, eco-friendly, and readily available technologies. The persistence, toxicity, bioaccumulation potential organic pollutants arising from various human activities pose substantial hurdles. While high-performance liquid chromatography coupled with high-resolution mass spectrometry (HPLC-HRMS) is a widely utilized technique for identifying multitude structures single elemental composition complicates structural identification. current HRMS MS/MS databases often can provide hits known molecules, these are erroneous or misleading when authentic standards unavailable.

Arsenic is a toxic carcinogen mostly found in subsurface environments. It released into groundwater via natural geological and hydrological processes. Consumption of such contaminated water leads to serious health crises for mankind. Developing countries South Asia, particularly the rural regions, have been severely affected by this environmental phenomenon. In India, government authorities implemented several remedial measures provide safe drinking habitations, ranging from utilization surface bodies (e.g., rivers, ponds, etc.) piped supply schemes establishment treatment units. This article attempts review scientific literature describing critical situation India's fourth most populous state West Bengal engineering advances made mitigation. The issue disposal or stabilization arsenic wastewaters generated units often not emphasized policy discussions. concluding note, proposes innovations necessary achieving effective mitigation region that involve both remediation waste management tandem sustainability.
