While the HBM4EU initiative is groundbreaking, it faces several challenges:
Data Harmonization: Ensuring consistent and comparable data collection methodologies across countries is complex but crucial for meaningful analysis. Ethical and privacy concerns: Protecting participants' privacy while using their data for research purposes is vital. Resource allocation: Adequate funding and resources are necessary to maintain and expand the initiative's scope. Public engagement: Raising awareness and understanding of biomonitoring among the public and stakeholders is essential for success.
