Are TRWP a form of microplastic?

There is no globally accepted definition of microplastics. However, our focus is not on how TRWP may or may not be categorized, but to study them to learn more about any potential impacts they may have on human health and the environment.

TRWP exist regardless of how we choose to categorize them. Our mission is to better understand the distribution of these particles in the environment and their potential impact on human health and the environment.

TRWP are tiny – less than 5 mm – and contain some polymeric material. According to some definitions, this would qualify TRWP as a form of microplastic.

The “microplastic” label is important because it helps draw broad attention to a complex multi-faceted societal challenge. A challenge that requires an evidence-based response and the engagement of a multitude of stakeholders.
