A researcher at the University of Queensland says current methods for detecting microplastics in human samples can be contaminated by lab plastics and can produce false positives, especially for polyethylene. The work suggests some reported microplastic levels in blood and tissue may be overstated, and that better sample handling is needed before health effects can be reliably assessed.
