Project Number # 4109-15

Investigating bioaccumulation of chemical pollutants adsorbed to Microplastics in the terrestrial environment

The aim of the project was to establish if organic pollutants such as brominated flame retardants that are adsorbed to particles of microplastics from personal care products are bioavailable to earthworms and if so, what is their potential to bioaccumulate in the earthworms. This was done by conducting controlled laboratory exposure experiments using earthworms in artificial OECD recommended soil and exposing them to microbeads extracted from a personal care product that were then contaminated with PBDEs. Following the exposure period PBDEs were extracted from the earthworm tissue using accelerated solvent extraction and analysed by gas chromatography mass spectroscopy (GC-MS).
