The research team at the National University of Ireland found on July 15 that there were plastic particles in deep-sea fish 300-600 meters deep in the Atlantic Ocean. These fish live in deep seas far from the land. The detection rate of plastic particles exceeds the overall 70 %, found in all 7 species of fish investigated.
The seven species of fish in this survey are rich in resources, such as tuna, dolphins, seabirds, etc., which play an important role in the marine food chain. The research team warned that 'plastic PCBs are adsorbed with polychlorinated biphenyls (PCB), etc. Contaminants, which tend to accumulate higher concentrations. It may have a negative impact on the deep-sea ecosystem and the human health of eating fish.'
From April to May 2015, the research team captured 7 species of lanternfish, about 3 cm in length, in the northwestern Atlantic Ocean about 1200 km from Newfoundland, Canada. A total of 233 deep-sea fish were surveyed. Plastics in the digestive tract of the fish were investigated. particle.
Fibrous plastic particles found in deep sea fish
Plastic particles were found in 73% of the 171 fish, with an average of about 2 and a maximum of 13. The number of plastic particles was higher than that of the previously reported cases in fish, and the detection rate was also significantly higher than in the Atlantic. 11% of the survey.
Lantern fish, etc., are called middle-class fish. They float near the surface of the ocean to find food at night, so it is easy to eat floating plastic particles into the body.
The same kind of lantern fish. The fish analyzed by the research and development team belong to different species.
Plastic particles refer to particles less than 5 mm in diameter. At the G7 Summit in June (G7), the EU and Canada passed a document stating the goal of reducing marine plastic waste, but Japan and the United States refused to sign.
