Researchers at NYU Langone Health reported detecting microplastics in prostate tumor tissue from a small group of men undergoing prostate removal surgery, with average concentrations about 2.5 times higher in tumor samples than in nearby noncancerous tissue. The team says the findings, scheduled for presentation Feb. 26, 2026, at the American Society of Clinical Oncology’s Genitourinary Cancers Symposium, add early evidence that microplastic exposure could be relevant to prostate cancer but do not establish cause and effect.
Researchers at the University of Vienna have determined that land releases more than 20 times as many microplastic particles into the atmosphere as the oceans, challenging prior assumptions. Their study, published in Nature, used global measurements to correct overestimated emission models. The findings highlight land as the dominant source, though uncertainties persist.

Researchers at the University of Michigan have discovered that common nitrile and latex lab gloves release particles resembling microplastics, potentially inflating pollution estimates. The study, led by Madeline Clough and Anne McNeil, traced contamination to stearates in the gloves during sample preparation. Switching to cleanroom gloves could reduce false positives significantly.
