Microplastics ingested through sea food is a major health hazard


Seafood eaters are unknowingly absorbing tiny pieces of plastic into their bloodstream and these have effects that are yet to be established. This is as per a research carried out by University of Ghent in Belgium. Such plastics that measure less than a millimetre across, are widely found in mussels, oysters and other shellfish.
Scientists have calculated that more than 99% of the microplastics pass through the human body - but the rest are absorbed by body tissues.
This has been reported in news.sky.com dated 24 January 2017.
As per the findings of researchers, Europeans currently consume up to 11,000 pieces of plastic in their food each year and fewer than 60 of these are likely to be absorbed and accumulate in the body over a period of time. However, the amount of plastic absorbed from our food will keep going up as plastic pollution in the ocean gets worse.
Incidentally, mussels feed by filtering around 20 litres of seawater a day and ingest microplastics by accident. Most of these are excreted, but, still, on an average each mussel contains one tiny fragment lodged in its body tissue. With the increase of plastic pollution in the ocean that will increase.
It has been predicted that by the end of the century, those who regularly eat seafood could be consuming 780,000 pieces of plastic a year, absorbing 4,000 of them from their digestive systems.
