Large Sample Volumes Improve Detection Reliability of Sparse Particles in Water: A Poisson Sampling Perspective
Summary
This study investigated the role of quorum sensing in plastisphere microbial communities, examining how bacteria on microplastic surfaces coordinate behavior through chemical signaling. The findings suggest that plastic surfaces may promote quorum sensing and associated collective behaviors including biofilm formation and potential virulence.
Abstract: Detection of dispersed particles in water systems, including microplastics and nanoplastics, is strongly influenced by stochastic sampling effects at low concentrations. When particle concentrations are sparse, the probability of detection in small sample volumes follows Poisson statistics, resulting in high variability and frequent false-negative results. This paper examines the implications of Poisson sampling variance for environmental monitoring and demonstrates how larger sample volumes substantially improve detection reliability. We advocate for volume-aware sampling strategies and provide quantitative guidance to support more robust monitoring of microplastics, nanoplastics, and other low-concentration particulates.
