Nearly two decades of world-leading research into the effects of marine plastics on our environment by Plymouth researchers, led by Professor Richard Thompson OBE, has resulted in repeated scientific breakthroughs which has influenced national and international legislation.
In 2004, the University first described the presence of microplastics in the marine environment, when in a seminal paper published in the journal Science, Professor Thompson and his team showed there had been rising levels of microscopic plastic debris evident in the plankton record since the 1960s.
This inspired a new field of scientific enquiry, with Professor Thompson and his team at the very forefront. They were the first to show the global distribution of microplastics, including in the Arctic and the deep ocean. The first to highlight the ingestion of microplastics by fish and other marine life. Plus, the first to show the role textiles and wastewater play in their source and transmission – with a single wash of clothing releasing more than 700,000 microfibers; and how some facial scrubs could contain up to 2.8 million microbeads.
