Breastmilk dioxin levels, specifically 2,3,7,8-tetrachlorodibenzodioxin (TCDD), were linked to infant bleeding in Dutch mothers. Polish mothers had significantly lower dioxin and furan levels, indicating lower pollution.

Area of Science:

  • Environmental Health
  • Pediatrics
  • Toxicology

Background:

  • Dioxins and furans are persistent environmental pollutants.
  • Exposure to xenobiotics can potentially interfere with infant physiological processes.
  • Phenobarbital, a drug, is known to affect coagulation, suggesting a possible mechanism for dioxin interference.

Purpose of the Study:

  • To measure dioxin and furan content in breastmilk of Dutch and Polish mothers.
  • To investigate the relationship between breastmilk dioxin levels and infant bleeding in the perinatal and neonatal periods.
  • To compare pollution levels between the Netherlands and Poland based on breastmilk contaminant concentrations.

Main Methods:

  • Analysis of dioxin and furan content in breastmilk samples from 14 Dutch and 5 Polish mothers.

  • Statistical analysis to correlate the levels of specific dioxins (2,3,7,8-TCDD, 2,3,4,7,8-PnCDF) and total toxic equivalents with infant bleeding episodes.
  • Comparison of contaminant levels between the two maternal cohorts.

    • Main Results:

    • A significant association was observed between the mean content of 2,3,7,8-tetrachlorodibenzodioxin (TCDD) in breastmilk and infant bleeding (P = 0.02).
    • No significant relation was found for 2,3,4,7,8-pentachlorodibenzofuran (PnCDF) or total toxic equivalents with infant bleeding.
    • Breastmilk from Polish mothers contained significantly lower levels of dioxins and furans (approximately four times lower) compared to Dutch mothers.

    Conclusions:

    • Elevated levels of 2,3,7,7,8-TCDD in breastmilk may be associated with bleeding complications in neonates.
    • Differences in prenatal transfer gradients between TCDD and PnCDF might explain the observed dissociation in results.
    • Higher dioxin and furan pollution levels are indicated in the Netherlands compared to Poland.
