Which size range is categorized as microdebris in the context of plastic debris?

5-20mm

1-5mm

Less than 1mm

Microdebris is typically categorized based on its size, particularly in studies related to plastic pollution. In this context, microdebris refers to plastic particles that are less than 1 millimeter in size. This classification is significant because microplastics can easily be ingested by a variety of organisms, impacting ecological health and the food chain.

Understanding this size range is critical for researchers and policymakers as they address the environmental challenges posed by plastic debris. Microdebris, due to its small size, can be widespread in aquatic environments and is often a result of the degradation of larger plastic items or the direct release of products that contain microplastics. Focusing on this specific size category helps in setting guidelines for monitoring and managing plastic pollution in ecosystems.
