German media said scientists warned that the micro plastic in the oceans and the toxic chemicals contained in them pose a serious threat to some large marine filter feeders such as whales, sharks and manta rays.
According to the report on February 5 by the German Broadcasting Corporation of Germany, published in the "Ecology and Evolutionary Trend" magazine, scientific research said that in order to capture plankton, this animal swallowed thousands of cubic meters of seawater daily, it can be directly through Contamination of sea water or swallowing micro plastic directly through contaminated prey.
The study said that plastics containing chemicals and pollutants can pile up for decades, thereby changing the biological processes of animals, changing growth, development and reproduction, reduce fertility.
Elisa Germarnov, the study's lead investigator, said in an email: 'Although the link between micro-plastic intake and filter-feeders' exposure to toxic substances remains unclear, we report on seabirds and small fish The study found that there is a link between them.
Reportedly, marine life is also at risk because of habitat coincidences with micro-plastic pollution hotspots, including the Gulf of Mexico, the Mediterranean Sea, the Bay of Bengal and the Coral Triangle, an area from Malaysia to the Solomon Islands Pacific Ocean.
Micro plastic is a tiny plastic with a diameter of less than 5 mm, harmful to marine life.
Reported that Germaunov said that many other animals such as manta rays are endangered species, so it is difficult to assess the accumulation of plastic by traditional methods such as stomach contents analysis.
She said: 'So we collected a small amount of tissue samples using non-lethal means and used advanced and sophisticated analytical tools to detect chemical traces.'
