The current SPTF team at RIT (Eddingsaas, Hernandez, Routenberg) has been working on blank testing of proposed analysis workflows to extract < 53 µm microplastics from lake water samples, with a goal of ensuring low contamination levels in the workflow prior to analyzing field samples. Field water samples were collected from Lake Ontario throughout 2025…

This post is about how I prevent contamination in the lab during experiments and material preparation. Contamination has been an issue in sample preparation despite efforts being made to minimize contamination. Current efforts include wearing cotton lab coats across all projects and the MMC, triple rinses with tap water followed by triple MilliQ water, working…

Introduction The LOMP Small Particle Taskforce is focused on developing a reliable and rigorous procedure for analyzing small microplastics in environmental samples. Our primary aim is to ensure that the data we generate accurately reflects the true microplastic population present in each sample. Achieving this requires careful attention to representativeness, verification, and contamination control throughout…
