Women and Children: Transboundary Management of PFAS — Implications for Health and Development

Abstract

Per- and polyfluoroalkyl substances (PFAS) represent a class of highly persistent synthetic chemicals used across multiple industries due to their hydrophobic and lipophobic characteristics. While these substances have delivered technological convenience, they have also generated complex, transboundary environmental and health challenges. The persistence, bioaccumulation, and mobility of PFAS allow them to cross national boundaries through water, air, food chains, and traded goods.
This paper examines the nexus between PFAS exposure, women and children’s health, and transboundary management systems. It highlights biological vulnerabilities, developmental consequences, socio-economic burdens, and policy frameworks necessary to protect these groups. The paper concludes that transboundary PFAS governance—anchored in capacity building, regional cooperation, and inclusive health strategies—is fundamental to sustainable development and human well-being.

1. Introduction

PFAS, often called “forever chemicals,” have been detected in virtually every environmental compartment—water, air, soil, biota, and human tissue. Their resistance to degradation stems from the strong carbon-fluorine bond, one of the most stable chemical linkages in nature.
While PFAS serve essential roles in non-stick cookware, textiles, fire-fighting foams, and cosmetics, their environmental legacy and global dispersion have triggered growing concern.
For women and children—particularly in low- and middle-income regions—the risk is amplified by:

  • Physiological susceptibility during pregnancy and infancy, when organs and systems are still developing.

  • Socioeconomic vulnerabilities linked to gender inequality, limited access to clean water, and poor health infrastructure.

  • Regulatory gaps that allow contaminated products and wastes to move across borders unchecked.

PFAS management has therefore transcended the realm of environmental chemistry—it is now a developmental and equity issue requiring regional and global collaboration.

2. Transboundary Dynamics of PFAS Pollution

PFAS contamination does not respect political or geographic boundaries. The transboundary nature of PFAS arises from:

  • Hydrological transport: Rivers and groundwater aquifers carry PFAS across borders, contaminating downstream communities and agricultural zones. For example, the Nile Basin—shared by 11 countries—faces cumulative PFAS risks from upstream industrial and urban discharges.

  • Atmospheric movement: Volatile PFAS precursors are dispersed by wind and rainfall, settling in distant regions. Studies have detected PFAS even in Arctic snow and remote African lakes.

  • Trade and consumer products: PFAS-laden textiles, cosmetics, and packaging cross customs barriers freely, exposing populations in importing countries.

  • Waste flows: Export of electronic waste, firefighting foams, and industrial residues can transfer PFAS to countries with limited disposal infrastructure, intensifying global inequity in chemical exposure.

These transboundary pathways complicate accountability and demand coordinated regional frameworks for prevention, monitoring, and response.

3. Vulnerability of Women and Children

3.1 Biological Susceptibility

PFAS readily accumulate in the bloodstream, placenta, and breast milk. Pregnant women can transmit these chemicals to the fetus via the umbilical cord, and infants can be exposed through breastfeeding.
Research indicates associations between PFAS exposure and:

  • Low birth weight and impaired fetal growth

  • Delayed neurological and immune development

  • Hormonal imbalances and thyroid dysfunction

  • Reduced vaccine efficacy in children

  • Increased risk of reproductive and developmental disorders later in life

3.2 Gendered Dimensions

Women often experience disproportionate exposure and responsibility:

  • They are primary users of PFAS-containing cosmetics and household products.

  • They handle water, food, and domestic waste, increasing contact with contaminated media.

  • As caregivers, they bear emotional, financial, and social burdens when children develop PFAS-linked health issues.

3.3 Intergenerational Transmission

PFAS effects are transgenerational—maternal exposure can influence the neuroendocrine systems and immune programming of offspring, shaping disease susceptibility into adulthood. This continuity transforms PFAS pollution into a developmental and human capital concern.

4. Health and Developmental Implications

4.1 Health Burden

PFAS exposure has been correlated with elevated cholesterol, reduced fertility, gestational hypertension, and certain cancers. For children, the outcomes extend to learning disabilities, behavioral disorders, and weakened immunity.
These health challenges undermine national health targets, strain medical systems, and increase economic dependency—particularly in low-resource settings.

4.2 Developmental and Economic Impacts

The cumulative effects of PFAS exposure on women and children undermine:

  • Educational attainment: Cognitive and behavioral disruptions reduce learning potential.

  • Labor productivity: Chronic illnesses limit workforce participation, especially among women.

  • Economic growth: Long-term healthcare costs, loss of productivity, and environmental remediation drain national resources.
    Thus, PFAS contamination indirectly hinders achievement of Sustainable Development Goals (SDGs) related to health (SDG 3), gender equality (SDG 5), clean water (SDG 6), and sustainable consumption (SDG 12).

5. Transboundary Management Frameworks

5.1 Global Agreements

PFAS management aligns with international conventions such as:

  • The Stockholm Convention on Persistent Organic Pollutants, which lists PFOS, PFOA, and related compounds for elimination or restriction.

  • The Basel Convention, governing transboundary movements of hazardous waste.

  • UNEP’s Global Chemicals Outlook and the Strategic Approach to International Chemicals Management (SAICM), which promote integrated chemical safety frameworks.

5.2 Regional and National Gaps

African and other developing regions face several challenges:

  • Absence of standardized PFAS monitoring and reporting protocols.

  • Inadequate laboratory and analytical capacity.

  • Weak enforcement of waste import/export regulations.

  • Limited public awareness and education on PFAS exposure.

5.3 Need for a Transboundary Governance Model

An effective model would include:

  • Shared regional databases and monitoring networks for PFAS in water, food, and biological samples.

  • Harmonized exposure limits and testing methodologies.

  • Cross-border rapid response units for pollution events.

  • Gender-sensitive policies integrating PFAS education into maternal and child health programmes.

6. Integrating PFAS Awareness into Training and Health Systems

Effective PFAS management begins with education. Integrating PFAS awareness into:

  • Maternal health clinics, ensuring healthcare workers understand PFAS exposure pathways.

  • Community health training, equipping women and youth to identify sources and advocate for safer practices.

  • Educational curricula, linking environmental chemistry with public health.

  • Industrial training programmes, focusing on safe production, disposal, and substitution with PFAS-free materials.

Capacity-building across borders enhances resilience, empowers women, and fosters equitable participation in chemical governance.

7. Policy Recommendations

  1. Establish Regional PFAS Monitoring Hubs: Create intergovernmental networks under regional economic blocs (e.g., EAC, SADC) for surveillance and data exchange.

  2. Harmonize Standards: Align national limits with WHO and UNEP guidelines to ensure equitable protection.

  3. Prioritize Maternal and Child Health: Integrate PFAS screening into prenatal care, nutrition, and child immunization programmes.

  4. Strengthen Waste Regulation: Ban importation of PFAS-containing waste and encourage clean production technologies.

  5. Support Research and Innovation: Fund development of PFAS alternatives and local remediation technologies.

  6. Empower Women in Environmental Leadership: Facilitate women-led research, advocacy, and policy design to ensure inclusive decision-making.

  7. Promote Public Awareness: Conduct mass communication campaigns on PFAS risks through media, schools, and community groups.

  8. Foster International Cooperation: Engage development partners in financing laboratory capacity, knowledge exchange, and pollution remediation.

8. Conclusion

PFAS pollution exemplifies the modern environmental dilemma—chemicals that defy degradation, respect no borders, and target the most vulnerable. Women and children, as biological and social sentinels of community health, face the deepest and most enduring impacts.
Transboundary management of PFAS is not merely a technical challenge; it is an ethical and developmental responsibility.
By strengthening regional collaboration, building capacity, integrating PFAS awareness into health systems, and empowering women’s leadership, nations can transform chemical safety from an environmental goal into a catalyst for sustainable development and human dignity.

  Impacts of Pit Latrine Waste on Early Puberty in Africa Introduction Across sub-Saharan Africa, pit latrines serve as the primary sanitation infrastructure for over 50% of urban populations and an even higher proportion in rural areas, providing a low-cost solution to the challenge of open defecation. These simple, often unlined pits collect human waste but pose significant risks to environmental and public health due to potential groundwater contamination. Emerging evidence suggests that chemical pollutants from pit latrines, particularly endocrine-disrupting chemicals (EDCs), may contribute to early puberty in children, especially girls, with far-reaching health, social, and educational consequences. Early puberty, defined as pubertal development before age 8 in girls or 9 in boys, is associated with increased risks of mental health disorders, reproductive health issues, and socioeconomic challenges, particularly in resource-constrained settings. In Africa, where sanitation inf...

  Health insurance affordability and the quality of life among low Socioeconomic Status (SES) individuals in Low- and Middle-Income Countries (LMICs)   Preamble: Whereas the right to health is a fundamental human right, it remains inaccessible to many, especially those of low socioeconomic status (SES) in low- and middle-income countries (LMICs); and whereas the affordability of health insurance is a critical factor that can enhance or impede access to necessary healthcare services; we recognize that the ability to obtain health insurance plays a pivotal role in determining the quality of life for individuals and families within these communities. Acknowledging that the lack of affordable health insurance options leads to a disproportionate burden of disease and financial hardship on low SES populations; and understanding that the provision of affordable health insurance is not only a matter of social justice but also an investment in the social and economic development ...

Child Health:  Dealing with Aflatoxins in Children’s Food Aflatoxins, produced primarily by Aspergillus flavus and A. parasiticus , are highly toxic and carcinogenic mycotoxins that contaminate key food crops in tropical and subtropical regions. In low- and middle-income countries (LMICs), especially across sub-Saharan Africa, chronic exposure to aflatoxins in staple foods poses grave health risks for children, including growth impairment, immunosuppression, developmental deficits, and increased vulnerability to infectious diseases. This paper explores the sources of aflatoxin contamination in children's food, its public health impacts, and proposes multisectoral policies and interventions to protect child health and nutrition, with a focus on evidence from Africa. 1. Introduction Aflatoxin contamination is one of the most pressing yet under-addressed food safety challenges affecting children in LMICs. Staple foods such as maize, sorghum, groundnuts, and dairy products are pro...
