Fig. 1

The percentage of measurements in the Toxicity of Microplastics Explorer database reporting different particle characteristics. Descriptions of particle characteristic categories are as follows: Shape, physical morphology (e.g., sphere, fragment, fiber); Polymer, material type (e.g., polystyrene); Density, material density; Charge, electrostatic properties/ zeta potential (e.g., positive, negative); Functional Group, chemical surface modifications (e.g., carboxylation); Particle Behavior, quantitative or qualitative descriptions of how particles behave in media (e.g., sedimentation, clumping, dispersed); Weathering, descriptions particle biofouling prior to exposures
