Women: Awareness about PFAS, Safety and Health Implications

Abstract

Per- and polyfluoroalkyl substances (PFAS), often termed “forever chemicals,” are a large class of synthetic compounds characterized by their extreme stability and resistance to degradation. Used for their water-, oil-, and stain-repellent properties, PFAS have become embedded in modern consumer culture—from cosmetics and menstrual hygiene products to cookware, clothing, and food packaging. Their persistence and bioaccumulative nature have raised major public health concerns, especially for women, who are disproportionately exposed through gender-specific products and physiological factors. This paper provides an in-depth exploration of PFAS exposure pathways among women, outlines the associated reproductive and systemic health effects, and proposes strategic policy actions to enhance women’s awareness, strengthen regulatory frameworks, and promote safer alternatives globally and within African contexts.

1. Introduction

PFAS comprise over 15,000 known compounds, including perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), and GenX chemicals. They are valued industrially for their thermal stability, surfactant properties, and resistance to oil and water. However, their chemical resilience also means that they do not break down easily in the environment or in the human body.

Women represent a critical population in PFAS discourse due to their roles as primary consumers of personal care products, managers of household environments, and biological transmitters of PFAS through pregnancy and lactation. The need for PFAS awareness among women transcends individual health—it encompasses reproductive justice, environmental equity, and intergenerational well-being.

2. Sources of PFAS Exposure among Women

PFAS exposure among women arises through multiple interconnected pathways, reflecting lifestyle, occupational, and environmental factors.

2.1 Personal Care and Cosmetic Products

Many cosmetic and hygiene products targeted at women contain PFAS to improve durability, smoothness, or waterproofing. These include:

  • Lipsticks, eyeliners, mascaras, and foundations containing fluorinated surfactants for long wear.

  • Lotions, serums, and sunscreens where PFAS enhance consistency and spreadability.

  • Nail polishes and setting sprays that utilize PFAS for rapid drying and resistance.

Dermal absorption and inadvertent ingestion (e.g., via lip products) contribute to direct internalization of PFAS.

2.2 Menstrual and Intimate Care Products

Menstrual pads, tampons, and reusable period underwear may be treated with PFAS for moisture resistance. The intimate nature of these products amplifies exposure risk, as mucosal absorption rates are higher than through ordinary skin contact.

2.3 Food and Water Pathways

Women—especially those in peri-urban and rural communities—are exposed to PFAS through contaminated drinking water, fish, and animal products. PFAS contamination has been reported near industrial areas, airports, and waste disposal sites. In regions such as East Africa, water contamination may occur through imported waste, landfill leakage, and unregulated industrial discharges.

2.4 Occupational Exposure

Occupational hazards arise in sectors where women form a significant workforce, such as:

  • Textile and apparel industries (treated fabrics).

  • Healthcare (PFAS-coated medical devices).

  • Hospitality and cleaning services (PFAS-containing cleaning products).

  • Firefighting (use of aqueous film-forming foams).

2.5 Environmental Contamination and Indoor Air

PFAS accumulate in household dust, indoor air, and soil, exposing women—especially homemakers and children—to chronic low-dose inhalation or ingestion.

3. Health Implications for Women

3.1 Reproductive and Hormonal Health

PFAS act as endocrine disruptors. They mimic or interfere with natural hormones such as estrogen and progesterone, leading to:

  • Menstrual irregularities and reduced ovarian reserve.

  • Delayed puberty and early menopause.

  • Polycystic ovarian syndrome (PCOS) and endometriosis.

  • Reduced fertility and subfecundity.

These outcomes have been documented in epidemiological studies linking PFAS levels to altered hormone signaling and follicle-stimulating hormone (FSH) disruptions.

3.2 Maternal and Neonatal Health

Pregnant women exposed to PFAS risk transmitting the chemicals to the developing fetus through the placenta. PFAS can cross biological barriers, accumulating in amniotic fluid and umbilical cord blood. Implications include:

  • Preterm birth and low birth weight.

  • Gestational hypertension and preeclampsia.

  • Immune dysregulation and reduced vaccine response in infants.

  • Neurodevelopmental and behavioral impairments in children.

Breastfeeding, though beneficial, can also be a PFAS transmission route, emphasizing the need for dual protection—maintaining breastfeeding promotion while addressing contamination sources.

3.3 Cancer and Systemic Diseases

Several PFAS are classified as probable human carcinogens.

  • Breast cancer: Long-term PFAS exposure is associated with elevated risk due to hormonal interference and oxidative stress.

  • Thyroid dysfunction: PFAS disrupt thyroid hormone regulation, particularly in women, who are already more susceptible to thyroid disorders.

  • Liver toxicity and metabolic syndrome: PFAS alter lipid metabolism and increase cholesterol levels, contributing to obesity and cardiovascular disease.

3.4 Psychological and Social Dimensions

Awareness of exposure—especially during pregnancy—can induce anxiety and emotional stress. Moreover, limited agency to choose PFAS-free products (due to economic or market constraints) perpetuates gender-based environmental inequities.

4. Awareness Gaps and Social Inequities

Despite growing global concern, awareness of PFAS among women remains low. In many African and developing contexts:

  • PFAS are not listed on product labels, making informed choices impossible.

  • Few awareness programs exist within reproductive or maternal health services.

  • Most public health messaging focuses on infectious diseases, neglecting chemical exposures.

  • Literacy and language barriers hinder comprehension of chemical safety information.

Socioeconomic disparities mean low-income women are more likely to use cheaper, PFAS-laden products and live near polluted sites, creating an environmental justice divide.

5. Policy and Governance Implications

5.1 Integrating PFAS Awareness into Women’s Health Programs

National health ministries should incorporate PFAS education into existing women’s health initiatives—such as maternal and child health clinics, family planning centers, and school-based health programs. Simple, culturally sensitive information materials can empower women to recognize and reduce PFAS exposure.

5.2 Regulatory and Labeling Reforms

  • Enforce mandatory labeling for PFAS-containing consumer products, particularly cosmetics, personal care, and menstrual hygiene items.

  • Support development of PFAS-free certification schemes to guide consumers.

  • Establish import control measures to prevent dumping of PFAS-laden products into African markets.

5.3 Environmental and Occupational Safety

  • Monitor PFAS contamination in drinking water and agricultural produce, especially near industrial areas and landfills.

  • Require industries and hospitals to implement safe waste management systems.

  • Provide occupational safety training and PFAS exposure monitoring for workers in high-risk sectors.

5.4 Research and Surveillance

Governments should fund gender-specific biomonitoring studies to track PFAS levels in women’s blood, breast milk, and urine. This data can guide public health interventions and inform global reporting frameworks under UNEP and WHO.

5.5 International Cooperation

African nations should strengthen participation in the Stockholm Convention on Persistent Organic Pollutants and collaborate on regional frameworks for chemical management. Partnerships with the European Union, UNEP, and academic institutions can support capacity building, technology transfer, and innovation in PFAS-free materials.

6. Policy Recommendations Summary

Focus AreaPolicy ActionExpected Outcome
AwarenessIncorporate PFAS education in reproductive health programsIncreased public literacy and informed choices
RegulationMandatory labeling and phase-out of PFAS in cosmeticsReduced exposure from consumer products
EnvironmentNational PFAS monitoring and cleanup programsSafer water and ecosystems
Occupational HealthPFAS safety training and protective regulationsReduced workplace exposure
ResearchGender-specific exposure studiesEvidence-based policy formulation

7. Conclusion

The silent infiltration of PFAS into women’s daily lives represents a profound public health challenge. Without clear awareness and regulation, women—especially in low- and middle-income countries—bear the hidden burden of exposure through products and environments they trust. Building PFAS literacy among women is an urgent policy priority that extends beyond chemical management; it is a matter of gender equity, reproductive rights, and generational health.

Through targeted education, stringent regulation, and global collaboration, societies can safeguard women and future generations from the enduring legacy of “forever chemicals.”

  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...
