You Are What You Eat, Microplastics in Porbeagle Sharks From the North East Atlantic:Method Development and Analysis in Spiral Valve Content and Tissue
Researchers worldwide are studying the environmental distribution and impacts of manufactured or environmentally fragmented small pieces of plastics, so called microplastics (<5 mm). These microplastics eventually build up in the marine environment, threatening marine ecosystems. The magnitude, f...

Microplastics were detected in all spiral valves, up to 10.4 particles per g wet weight (w.w.) content and 9.5 particles per g w.w. tissue.
