Thames Manta Project

 Sampling for microplastics on the Thames and Medway.

Despite a number of pieces of work on the Thames and microplastics, there has been no strategic or temporal study of microbeads on the Thames or Medway Estuaries. However with the ban coming in 2018 presents a key point to start to monitor the improvement such interventions make on the environment.
