First evidence of GRP boats’ “cancerous” impact on aquatic life

The ‘really worrying’ findings by University of Brighton researchers who undertook studies off the coast of Hampshire and West Sussex have worldwide implications, yet there is no practical solution for recycling fibreglass boats in sight, with a boom in boating, plus increasing numbers of early glass reinforced plastic (GRP) vessels reaching end of life. Dr Corina Ciocan, Principal Lecturer in Marine Biology at the School of Applied Sciences at the University of Brighton, told PBO it took a lot of detective work to discover exactly what they had found. Embedded in oysters and other aquatic life, the shards were found as part of an initial study focused on microplastics, and are 10 times thinner than human hair. She said: “We were looking at contamination of plastic in the water, in the sediment and in the oysters. In the oysters we found many, many strands we couldn’t explain, no one had reported it before. “The oysters had been collected from in front of a boatyard, and we found ‘e-type glass’ which is mostly used in composite materials. The dimension of the strands corresponded to tiny fragments that usually relate to cutting reinforced glass plastic material in boatyards. “It was like uncovering the tip of the iceberg, because nobody had published anything like this before – we were opening Pandora’s Box.” It is believed that the fibreglass is causing ‘asbestos-like’ damage to organisms such as oysters and mussels. Dr Ciocan said: “The work done in boatyards and the degradation of old boats have a massive impact on aquatic mammals, water fleas and mussels.” Cancerous effect Marine biologist Dr Ciocan’s expertise is in functional ecotoxicology, focusing on biological responses of marine organisms to environmental stressors. “My opinion, which is backed by my esteemed chemist colleagues, is that it has the attributes of asbestos – that upon entering the organism, it severs the flesh and becomes embedded. The organism develops inflammation, tumours and cancers. “Boat abandonment and a lack of legislation for end-of-life boats and the lack of a recycling solution are all attributed – there is no environmentally friendly way of disposing of it.” The specialist team of University of Brighton researchers started their collaboration with Chichester Harbour Conservancy four years ago, prompted by concerns about microplastic pollution in the harbour. Dr Ciocan said: “They wanted to know ‘What are the levels and where do they come from’ – sewage effluent or the tide? “One of the particular concerns was related to the native oyster and pollution in the harbour, which was a very successful oyster fishery for centuries, able to support about 40 fishing boats until 2018 when the fishery was closed by the Sussex Inshore Fisheries and Conservation Authority due to the low number of oysters.” Article continues below… Following the success of the Chichester Harbour Microplastics Symposium, further studies are now looking at two components from fibreglass: The plastic component “which is nasty in itself and has a huge impact on the reproduction in animals and humans and adds to … Continue reading First evidence of GRP boats’ “cancerous” impact on aquatic life
