According to Japanese media reports, a team from Tokyo University of Agriculture and Engineering Takada Hidekiaki and others recently confirmed that in the bivalve organisms on the shores of Zamami Island in Tokyo Bay and Okinawa Prefecture, a large number of microscopic marine pollution problems have accumulated. Plastic'.
Data Map: Seashells.
According to reports, the team stated that microplastics had been found in salmon in Tokyo Bay in the past, and that shellfish have only preceded the detection of microplastics overseas. Currently, biopesticides are readily ingested by organisms in bivalve organisms. There are more tiny particles with a diameter of 0.02 to 0.08 mm. The team pointed out: 'It is necessary to investigate in detail the effects on shellfish survival and ecological environment.'
From 2015 to 2017, the team collected sea rainbows and clams in the Tokyo Bay of Tokyo and Kawasaki, and inspected the body of the stony clams in Zamami Island.
Micro-plastics were detected in all 27 shells collected. The largest number of particles was the shellfish of Zamami Island, which contained 23 particles per gram. More particles were detected in the Bayou Bay Estuary, the sea of Kawasaki City. Rainbow contains 10 particles per gram. It is reported that fibrous microplastics that have not been detected in organisms in Japan have also been confirmed. Japanese media claimed that there is a large amount of plastic waste on the coast of Zamami Island, which may be caused by shellfish in vivo. The reason for more particles.
The British Brunel University team and other teams published research results this month, saying that there are many micro plastics in the mussels that are sold on the market. The contamination of shellfish is likely to be spread all over the world.
It is reported that microplastics are particles less than 5 mm in diameter produced by the garbage in the ocean and turned into small debris. During the Group of Seven (G7) summit in June, the European Union and Canada adopted the goal of reducing the value of marine plastic waste. The document, Japan and the United States refused to sign, again caused concern.
