2015) Aims of the study Investigate the presence of microplastics inside the guts of the hydrozoan Blackfordia virginica. [...] virginica and 1 water sample each month • Digested H O • Filtration using GF/C filters2 2 30 % (in the • MPs counted, measured, and presence of a Fe(II) for water classified according to colour samples) and type • Polymer identification using micro-FTIR Results Blackfordia virginica size 2021 highest abundance of B. [...] virginica ingested microplastics Abundance of microplastics ingested between 0.8 and 3 MP/medusae (July/October and November) and in water between 7.5 to 20 MPs m-3 (August and November). [...] virginica individuals contained microplastics in their guts; • selected against the most common colour and type occurring in the water (transparent and fibers), and the most abundant microplastics size range was different inside B.
