Tiny fragments of glass fibre widely used to make small boats around the world have been found in the marine food chain for the first time.<\/p>\n

Scientists at the universities of Portsmouth and Brighton found the glass shards, just a fraction of a millimetre long, in shellfish caught off the south coast of England.<\/p>\n

<\/div>\n

The needle-shaped fragments of fibreglass, or glass reinforced plastic, were so sharp that some had speared biological tissue.<\/p>\n

Professor Faye Couceiro, lead researcher and an expert in environmental pollution, told Sky News more research was urgently needed to understand the risk to people who consume oysters and mussels.<\/p>\n

\u201cThe glass fibre is causing inflammation in all of the areas it is found (in the shellfish tissue),\u201d she said.<\/p>\n

<\/div>\n

\u201cWe don\u2019t know what that means for human health yet. But it\u2019s likely something similar will be happening, so the question is at what concentration does that become a problem.\u201d<\/p>\n

Fibreglass is a mesh of glass filaments that is embedded in plastic resin. The material is strong, light and easily shaped to make boats.<\/p>\n

But when it is cut or sanded, or it degrades with age, it creates a fine dust of fibres which are easily washed into the sea.<\/p>\n

The researchers studied oysters and mussels caught near an active boatyard in Chichester Harbour, a popular sailing destination in southern England.<\/p>\n

Using a high-powered microscope they found up to 11,220 fibreglass particles per kilogram of oysters, and 2,740 per kilogram of mussels.<\/p>\n

The vast majority were in the stomachs of the shellfish and would be expelled if they were put in clean water before being sold to consumers.<\/p>\n

But several hundred glass fragments were found in the flesh and would have been consumed by anyone eating the mussel or oyster.<\/p>\n

\u201cI was surprised by the number,\u201d Prof Couceiro said. \u201cI don\u2019t think it\u2019s panic stage. Don\u2019t stop eating them.\u201d<\/p>\n

But she added that the shellfish industry must now look at ways of cleaning out as many of the fragments as possible prior to consumption.<\/p>\n

Oysters and mussels are already known to accumulate microplastic in their body tissues.<\/p>\n

They are filter feeders, sucking in several litres of seawater every minute to extract particles of food.<\/p>\n

But they also trap fibres and other fragments polluting coastal waters.<\/p>\n

Gordon Watson, professor of marine zoology at the University of Portsmouth, said the fibres have a significant impact.<\/p>\n

\u201cThese mussels grow more slowly,\u201d he said.<\/p>\n

\u201cBut they are also eaten by other organisms, like fish, and could pass the particles on, so they accumulate in the food chain.\u201d<\/p>\n

Although the research focused on shellfish near an active boatyard, the scientists said the problem was likely to be more widespread.<\/p>\n

Prof Couceiro said fibreglass boats should be disposed of in landfill if they can\u2019t be recycled at the end of their life.<\/p>\n

\u201cLandfill is expensive, so people drill a hole and the boat sinks to the bottom,\u201d she said.<\/p>\n

\u201cIf there was registration of vessels we would know who they belonged to and we would be able to make sure that they were disposed of properly,\u201d she said.<\/p>\n

\u201cWe need to prevent these particles getting into the environment.\u201d<\/p>\n<\/p>\n
