Current opinion: What is a nanoplastic?,

With the large amount of attention being given to microplastics in the environment, several researchers have begun to
consider the fragmentation of plastics down to lower scales (i.e., the sub-micrometer scale). The term “nanoplastics” is still under debate,
and different studies have set the upper size limit at either 1000 nm or 100 nm.
The aim of the present work is to propose a definition of nanoplastics, based on our recently published and unpublished research
definition of nanoplastics. We define nanoplastics as particles unintentionally produced (i.e. from the degradation and the
manufacturing of the plastic objects) and presenting a colloidal behavior, within the size range from 1 to 1000 nm.
