# TWP

The UK Centre for Ecology & Hydrology (UKCEH) project team recently published a comprehensive study on the field. 2 It was carried out on behalf of Department of environment, food and rural affair (DEFRA) with the aim to detect and quantify the occurrence of different type of microplastic in UK river and sediments, including the assessment of TWP though an indirect quantification of 6-PPD, which was chose a a molecular marker due to its particular chemical structure and persistency in the environment. Microwave assisted extraction (MAE) proved to be a reliable and effective technique to obtain extraction of those types of additives from the treated sediments and soils. To perform MAE, the group of research used Milestone’s ETHOS X benchtop microwave extraction system with fastEX 24 eT rotor.
