there may be way less microplastics than first estimated. https://pubs.rsc.org/en/content/articlelanding/2026/ay/d5ay01801cIn this work, we illustrate that dry surface contact with nitrile and latex laboratory gloves can cause overestimations of microplastics (mean 2000 false positives per mm2) when using traditional library matching approaches. We recommend a nitrile cleanroom glove (mean 100 false positives per mm2) to reduce contamination. ... Glove use was recommended by 81% of articles. Notably, only two reviews mentioned that contact with the sample should be limited. https://pubs.acs.org/doi/10.1021/acs.est.4c12599The PVC pyrolysis products showed greatest variability in the calculated PVC concentrations for Method 2, often showing higher concentrations for either or both of the alkylated naphthalenes. This variability also suggests the presence of a PVC interference and indicates that monitoring the alkylated naphthalenes alone could result in a false positive for PVC in these samples. The calculated concentrations for Methods 1 and 3 were not higher than the blanks, indicating these are not a true PVC result. Previous studies suggest these polycyclic aromatic hydrocarbons can form from pyrolysis of triglycerides and fatty acids.though microplastics still are dangerous; https://www.epa.gov/pfas/our-current-understanding-human-health-and-environmental-risks-pfas https://pmc.ncbi.nlm.nih.gov/articles/PMC8306913/ https://pubmed.ncbi.nlm.nih.gov/41804233/ just we are likely consuming way less than is reported, so just the whole statistics side of the research needs to be restarted probably
