Summary
This review synthesises current knowledge on arsenic contamination of drinking water across global contexts, integrating evidence on contamination sources, human health impacts from chronic low-level exposure, and available remediation approaches. The authors examine both geogenic and anthropogenic sources of arsenic, and evaluate technical and scalable solutions for affected populations. The work addresses a significant public health concern, particularly in regions with naturally high groundwater arsenic levels.
UK applicability
Whilst acute arsenic contamination is not widespread in UK public water supplies due to stringent drinking water standards, the review's synthesis of remediation technologies and health impact evidence may be relevant to understanding historical exposures in specific UK regions and informing water safety policy.
Key measures
Arsenic concentration in drinking water; health outcomes associated with exposure (likely cancer, cardiovascular and metabolic endpoints); remediation technology effectiveness and accessibility
Outcomes reported
The paper reviewed evidence on sources of arsenic contamination in drinking water globally, documented associated health impacts in exposed populations, and synthesised available remediation and treatment technologies. It likely collated epidemiological data linking arsenic exposure to disease burden and assessed the efficacy of various intervention approaches.
