London, August 12 (Reuters) – plastic residues have been found in five different seafood samples, and there are also significant differences in the amount of plastic in different kinds of seafood, according to a study released by the University of Exeter on the 12th.
researchers from the University of Exeter and the University of Queensland in Australia jointly carried out the study to assess the impact of marine plastic pollution, and the results were published in the US monthly journal.
reports that researchers bought oysters, prawns, squid, crabs and sardine in a seafood market in Australia and assessed the level of plastic residues in these seafood by technical means.
results showed that the content of plastic residue in squid was 0.04 mg per gram, 0.07 mg for prawn, 0.1 mg for oyster, 0.3 mg for crab, 2.9 mg for sardine. According to Francesca Ribeiro, a scholar of University of Queensland and a
report author, if the average daily consumption is calculated, the average consumer can eat about 0.7 mg of plastic per oysters or squid, while the plastic that eats a sardine can even reach 30 mg, which is about the weight of a grain of rice.
the researchers said that this study showed that the levels of plastic in different kinds of seafood were quite different. The scientific community is not fully aware of the health risks caused by the intake of such plastic residues, but the research may help deepen this understanding.
