E-waste Pollution Increases Children's Hypertension Risk

A study published in Environment & Health reveals that children living in communities where electronic waste is dumped and burnt are at a fourfold increased risk of developing hypertension. The research, conducted in October 2022, involved 426 children without a previous history of hypertension residing in an e-waste recycling area in China.

It found that exposure to toxic metals and volatile organic compounds (VOCs) is linked to changes in gut-related metabolic pathways and blood pressure regulation. The study recorded a hypertension prevalence of 12.7 percent among the children, significantly higher than national estimates.

Researchers analyzed urine samples for 18 metal(loid)s, including lead and cadmium, and metabolites indicating VOC exposure. They identified significant associations between certain pollutants and blood pressure levels, with urinary cobalt and gallium linked to systolic blood pressure, and selenium and tin associated with diastolic blood pressure.

The findings raise concerns as global e-waste continues to rise, particularly affecting developing countries.
