Are TRWP a threat to my health?

Our sponsored studies have indicated that TRWP do not pose risk to human health, and we’re engaged in continued research to improve this knowledge.

Specifically, studies into airborne TRWP have concluded that TRWP make a relatively low contribution to particulate matter of the size fractions of most concern to human health. Additionally, inhalation studies suggest that TRWP is unlikely to pose risk to humans through airborne exposure.

With relevance to improving scientific understanding of potential human exposure to TRWP, our ongoing and planned research includes sampling of TRWP in the environment, studying the degradation of TRWP, modelling the fate and transport of TRWP in air, rivers, soil, and oceans, and investigating the potential impacts on organisms of long-term exposure to TRWP.
