Emergency of per- and polyfluoroalkyl substances in drinking water: Status, regulation, and mitigation strategies in developing countries
AI summary Read the abstract
This review examines the growing threat of per- and polyfluoroalkyl substances (PFAS) in drinking water across developing nations, finding critical gaps in monitoring data especially in Africa, and calling for economically viable removal technologies tailored to low-resource settings as regulations begin to emerge.
The detection of per- and polyfluoroalkyl substances (PFAS) in water presents a significant challenge for developing countries, requiring urgent attention. This review focuses on understanding the emergence of PFAS in drinking water, health concerns, and removal strategies for PFAS in water systems in developing countries. This review indicates the need for more studies to be conducted in many developing nations due to limited information on the environmental status and fate of PFAS. The health consequences of PFAS in water are enormous and cannot be overemphasized. Efforts are ongoing to legislate a national standard for PFAS in drinking water. Currently, there are few known mitigation efforts from African countries, in contrast to several developing nations in Asia. Therefore, there is an urgent need to develop economically viable techniques that could be integrated into large-scale operations to remove PFAS from water systems in the region. However, despite the success achieved with removing long-chain PFAS from water, more studies are required on strategies for eliminating short-chain moieties in water.

Revisiting the “forever chemicals”, PFOA and PFOS exposure in drinking water
AI summary Read the abstract
Researchers reviewed 180 years of evidence on PFOA and PFOS — two of the most detected 'forever chemicals' (PFAS) in drinking water — finding that contamination rates increased sharply between 2018 and 2019, and that many developing countries still lack the regulations or technology to address the problem. The review calls for stronger global monitoring systems and improved filtration technologies to protect drinking water supplies.
Effects and Global Diversity of Emerging Contaminants in Drinking Water
AI summary Read the abstract
Emerging contaminants including microplastics, PFAS, and pharmaceuticals are widely distributed in drinking water globally, with conventional treatment methods inadequate to remove many of them and significant regulatory gaps in low- and middle-income nations. Advanced treatment technologies and sustainable approaches like biochar adsorption and bioremediation show promise but require stronger policy frameworks to achieve meaningful protection.

PFAS in Drinking Water: Risk Factor for Human Life, Modern Sources of Pollution, Methods of Control and Approaches to Water Purification (review)
AI summary Read the abstract
A comprehensive review of PFAS contamination in drinking water sources documents their widespread detection in rivers, groundwater, soils, and even military ammunition, highlighting carcinogenic, immunotoxic, endocrine-disrupting, and organ-damaging properties alongside the limitations of current detection and removal methods. This is directly relevant to microplastic research because PFAS chemicals are key components of many plastic formulations and readily adsorb to microplastic surfaces, making microplastics a vector for PFAS co-exposure via drinking water.
