Bavarian breast milk analysis shows decreasing pesticide levels but declining sample numbers. A new pilot study introduces an updated monitoring program for environmental chemicals like dioxins and PCBs.

Area of Science:

  • Environmental Health
  • Toxicology
  • Public Health

Background:

  • For over 20 years, the Bavarian Health and Food Safety Authority monitored persistent pesticides and organohalogens in breast milk.
  • Monitoring revealed a decreasing trend in chemical levels but a concurrent decline in sample submissions, raising data reliability concerns.
  • The existing analysis spectrum was deemed toxicologically outdated, necessitating a revised monitoring approach.

Purpose of the Study:

  • To develop and pilot a new concept for breast milk monitoring in Bavaria.
  • To assess concentrations of polychlorinated dibenzodioxins (PCDD), polychlorinated dibenzofurans (PCDF), and dioxin-like polychlorinated biphenyls (dl-PCB) in human milk.
  • To establish a framework for tracking emerging contaminants like polybrominated diphenyl ethers (PBDE) and perfluorinated compounds (PFC).

Main Methods:

  • Pilot study involving analysis of breast milk samples from 43 women in Bavaria.
  • Quantification of PCDD, PCDF, and dl-PCB concentrations using established toxicological methods.
  • Development of the Bavarian Monitoring of Breast Milk (BAMBI) program concept.

Main Results:

  • Average concentrations reported: PCDD at 4.93 pg WHO-TEQ/g fat, PCDF at 4.98 pg WHO-TEQ/g fat, and dl-PCB at 9.92 pg WHO-TEQ/g fat.
  • The pilot study successfully tested the feasibility of the new monitoring concept.
  • Initial data provides a baseline for PCDD, PCDF, and dl-PCB in Bavarian women's breast milk.

Conclusions:

  • The established breast milk monitoring program requires modernization due to outdated substance lists and declining sample numbers.
  • The new BAMBI program aims to provide reliable, up-to-date data on environmental chemical burdens in breast milk.
  • BAMBI will track temporal trends and incorporate analysis of novel chemicals lacking sufficient German data.
