Early Life Exposure to Multiple Chemicals in 6 European Countries

This multi-country study assessed early life exposure to multiple environmental chemicals including pesticides, heavy metals, phthalates, and bisphenols in pregnant women and children across six European countries. The study was part of the Human Biomonitoring for Europe (HBM4EU) initiative.

The results demonstrated that European children and pregnant women are exposed to complex mixtures of environmental chemicals from the earliest stages of life. Glyphosate was detected in a significant proportion of participants across all six countries. Importantly, the study found that no single chemical exposure occurs in isolation — individuals are exposed to dozens of chemicals simultaneously.

The cumulative and combined effects of these multiple exposures may pose greater health risks than any single chemical alone, yet regulatory risk assessment continues to evaluate chemicals one at a time, potentially vastly underestimating real-world risk.

Key Findings

• •Children and pregnant women in all six European countries showed exposure to multiple environmental chemicals simultaneously.
• •Glyphosate was detected in participants across all countries studied.
• •The average participant was exposed to more than 50 different chemical substances.
• •Combined exposure effects may be greater than the sum of individual chemical effects.
• •Current single-chemical regulatory assessments vastly underestimate real-world risk from chemical mixtures.

Methodology

Cross-sectional biomonitoring study within the HBM4EU framework. Urine and blood samples were collected from pregnant women and children aged 6-12 in France, Germany, Denmark, the Netherlands, Spain, and Slovenia. Samples were analyzed for over 100 chemical biomarkers using multi-analyte LC-MS/MS and GC-MS methods.

Why This Matters for Families

This study reveals that children across Europe are bathed in a chemical mixture from before birth. For families, it reinforces that reducing exposure to one chemical at a time is not sufficient — a comprehensive approach to reducing chemical exposure through organic food, low-risk household products, and clean water is needed to meaningfully protect children's health.
