In this study, the appropriate quantity of particles on a filter to allow effective particle analysis to be performed was determined by performing numerical experiments.\nThe larger the number of particles and the larger the particles, the smaller the proportion of isolated particles. An isolation ratio of 99% requires a particle density on the filter of 1.28 particles mm−2 if the particle size is 50 µm or of 0.351 particles mm−2 if the particle size is 100 µm.\n\n•Appropriate number of particles for small plastic particle analysis was determined.\n•Numerical experiments to determine particle distributions on a filter were performed.\n•Particle number for a 99% isolation ratio was determined."}]},"item_3_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier B.V.
