Summary

This chapter reviews how microplastics aggregate with each other and with natural particles like sediment and algae in water, affecting their transport, fate, and biological availability. Heteroaggregation with natural colloids is more common than microplastic-to-microplastic clumping, which has important implications for how microplastics move through aquatic environments.

Study Type Environmental

This chapter provides a critical overview of the existing literature investigating the aggregation of microplastics in water. There are two types of aggregation, including homoaggregation with the same type of particles and heteroaggregation with various types of particles. Heteroaggregation is prone to occur than homoaggregation for particulate plastics due to the large number of natural colloids, including suspended sediment, and organisms like algae and seaweeds in natural waters. The experimental methods including scanning electron microscopy, dynamic light scattering, and flow cytometry technique are applied to characterize the aggregation of particulate plastics. The size and shape of particulate plastics could affect their aggregation rates by affecting the specific surface areas and the forces between the approaching particles. Ionic strength and ion valence strongly affect the aggregation behavior of particulate plastics in water. In natural waters, aggregates of particulate plastics have dimensions from nano-meters to centimeters or larger, and this results in their various toxicity levels towards organisms.
