A new study reveals that children exposed to toxic e-waste pollutants are at a much higher risk of developing high blood pressure, as harmful metals and chemicals disrupt the body’s natural blood pressure regulation.

Highlights:
  • Children in e-waste regions were four times more likely to develop hypertension
  • Exposure to toxic metals and volatile organic compounds (VOCs) was linked to disturbed metabolic pathways
  • Pollutants may alter gut metabolism and oxidative stress, affecting heart and blood vessel health
Children living near electronic waste (e-waste) recycling sites may be facing more than just pollution — they’re also at risk of developing high blood pressure, a condition once rare in the young (1 Trusted Source

A new study published in Environment & Health reveals that children exposed to harmful metals and volatile chemicals from e-waste dumps were about four times more likely to develop hypertension than those in other regions (12.7% vs. 3.1%).

How E-Waste Pollution Affects the Body

E-waste — discarded computers, phones, and other electronics, often release toxic metals like lead, arsenic, and cadmium, along with volatile organic compounds (VOCs) such as benzene and styrene, when dismantled or burned.

These substances can enter the bloodstream and alter key metabolic pathways, especially those linked to the gut and cardiovascular system. The result? Disrupted blood pressure regulation and early signs of hypertension in children.


Inside the Study

The research involved 426 children from an e-waste recycling region in China. Scientists analyzed urine samples to measure 18 metal(loid)s and 15 VOC metabolites, along with over 180 metabolic markers using advanced techniques.

Children’s blood pressure was measured following standard pediatric guidelines. Statistical models and machine learning analysis showed that exposure to certain metal(loid)s — including cobalt, gallium, and tin — and VOCs was strongly associated with elevated blood pressure.


The Hidden Role of the Gut

One of the study’s most striking findings was the link between pollution and the gut’s metabolic activity.

Changes in metabolites such as l-glutamine and N-phenylacetyl-l-glutamine (PAGln) suggest that gut bacteria may play a role in how the body responds to toxic exposure. Pollutants may disrupt gut microbiota, triggering oxidative stress and hormonal imbalances, which over time could raise blood pressure.


Future Implications

This research sheds light on an emerging public health threat. As global e-waste continues to rise, millions of children in low-income regions may face similar risks.

Experts stress the need for safer recycling practices, strict pollution controls, and regular health monitoring for children in affected areas.

The study also opens new doors for early detection and prevention, using metabolomic profiling to identify at-risk children before hypertension becomes irreversible.

Frequently Asked Questions

Q: What is e-waste?

A: E-waste refers to discarded electronic items like phones, computers, and TVs that release toxic substances when burned or dismantled.

Q: Why does e-waste cause high blood pressure in children?

A: Toxic metals and chemicals from e-waste disrupt the body’s metabolism and cardiovascular functions, leading to elevated blood pressure.

Q: How much higher is the risk?

A: Children in e-waste regions were about four times more likely to have hypertension than the national average.

Q: Can the effects be reversed?

A: Some metabolic disruptions may improve with reduced exposure, but long-term damage to heart and vessel health is possible.

Q: What can be done to protect children?

A: Safer recycling, strict waste management policies, and regular screening for children in affected areas are key prevention steps.
