Marine Littermicrolitter Microlitter: (Guidance on Monitoring of Marine Litter in European Seas 2013 MSFD Technical Subgroup on Marine Litter) Section 4.4 of the MSFD descriptor 10: ‘’Amount, distribution and composition of microparticles. The attribute will establish baseline quantities, properties and potential impacts of microparticles. Microplastic is likely to be the most significant part of this.’’ Microparticles of a range of common material types including glass, metal, plastic and paper litter are undoubtedly present in the environment… The protocols outlined here focus on microplastics as descriptor 10 considers these to be the most significant component of the microlitter in the environment. …but relative proportions of material types will be influenced by the physical conditions of the habitat sampled, for example metal and glass microlitter is not likely to be found at the sea surface.

Marine Littermicrolitter Microlitter: (Guidance on Monitoring of Marine Litter in European Seas 2013 MSFD Technical Subgroup on Marine Litter) When first described the term microplastic was used to refer to truly microscopic particles in the region of 20 μm (micrometers 1 µm = 1 × 10−6 m) diameter (Thompson et al. 2004). The definition has since been broadened to include all particles < 5 mm (Arthur et al. 2009). EMODnet Chemistry 3 1st TWG meeting, 4-5 April 2017
