Doubts Grow Over Microplastics in the Human Body

Researchers are questioning how microplastics are detected in human tissues, pointing to contamination and lack of validation in key studies. An International Science Council review catalogs about 7,000 studies on the topic; meanwhile new detection methods from the Medical University of Vienna aim to improve accuracy, though broad consensus may take years. While some scientists defend findings, experts urge cautious interpretation and measured policymaking to avoid alarm.
