Experts Call for Rigorous Chemical Testing to Address Rising Child Health Risks

Scientists warn unchecked chemical production severely threatens children’s wellbeing, urging reforms akin to prescription drug regulations to safeguard public health.

• Consortium urges laws prioritising child health over chemical production
• Calls for independent, premarket testing similar to pharmaceutical standards
• Emphasises mandatory post-market monitoring to detect long-term effects

An international consortium of scientists has issued a strong appeal for stricter chemical regulations, citing mounting evidence that inadequate oversight of synthetic chemicals and plastics poses a serious threat to child health worldwide. Their new report, published in the New England Journal of Medicine, highlights the rapid increase in non-communicable diseases (NCDs) among children, ranging from childhood cancer to neurodevelopmental disorders, and emphasises that unbridled chemical production may be a leading contributing factor. They warn that current legal frameworks are insufficient, with fewer than 20 per cent of existing chemicals having undergone comprehensive toxicity testing, and almost no post-marketing surveillance.

Call for Comprehensive Testing

In their report, co-authors from the Consortium for Children’s Environmental Health urge governments worldwide to adopt chemical regulations mirroring those used for prescription drugs. As Boston College epidemiologist Philip Landrigan, MD, and his colleagues emphasise, “Under new laws, chemicals should not be presumed harmless until they are proven to damage health.” They argue that manufacturers must conduct “rigorous, independent, premarket testing” to demonstrate product safety prior to market release, reversing the long-standing practice of allowing chemicals to circulate with minimal scrutiny.

Additionally, the authors propose that companies be held accountable for ongoing product monitoring, much like the pharmacovigilance processes employed in the pharmaceutical sector. This would require manufacturers to track and report any adverse health outcomes tied to their products, ensuring that risks, such as the documented rise in male reproductive birth defects and increased rates of childhood cancers, are identified and addressed promptly. By incorporating these measures, the consortium believes the growing burden of NCDs in children could be significantly reduced.

Prioritising Children’s Wellbeing

Central to the report is the argument that present regulatory gaps disproportionately affect children, who are more susceptible to chemical exposures due to their developing biological systems. Over the last 50 years, alarming rises have been observed in conditions such as paediatric asthma, neurodevelopmental disorders, and paediatric obesity. The authors note that many of these trends are linked to synthetic chemicals, which in turn are largely derived from fossil fuels like oil and coal.

In calling for a more precautionary approach, the consortium outlines a plan that spans stricter premarket evaluations, mandated chemical footprinting, and the development of safer, more sustainable molecules. According to the authors, health protection must take precedence over unrestrained chemical production, with a shift in industry practices that minimises reliance on fossil-carbon feedstocks and prioritises child health. The report proposes the creation of a global chemicals treaty and a new legal paradigm in which products are only permitted if their safety can be clearly demonstrated.

Lead author Landrigan, who directs Boston College’s Observatory on Planetary Health, underscores the urgency of this issue: “Pollution by synthetic chemicals and plastics is one of the great planetary challenges of our time. It is worsening rapidly. Continued unchecked increases in the production of chemicals based on fossil carbon endangers the world’s children and threatens humanity’s capacity for reproduction.” The consortium warns that if legal reforms do not keep pace with industrial expansion, the toll on children’s health will continue to rise.

Researchers across the UK will watch any policy shifts arising from the consortium’s call to action. If implemented, these proposals could drive more robust industrial practices and transparency in chemical manufacturing, fostering healthier environments for young people. With child health at the centre of debate, scientists, regulators, and industry stakeholders face a pivotal moment for chemical governance.
