Lab Consumables Bias Environmental Monitoring

Researchers found that disposable nitrile and latex gloves shed stearate particles that look like microplastics in common lab analyses, producing false positives unless cleanroom protocols are used. The contamination can transfer to air, water, and other samples and is chemically similar enough to some plastics to confound routine tests. — If simple lab consumables can skew pollution measurements, many reported environmental baselines, policy decisions, and cleanup priorities may need reexamination and stronger methodological standards.
