Seafood stuffed with microplastics: each sample found to be problematic

Seafood stuffed with microplastics

The scientists conducted a study of the state of seafood, during that they were shocked by the result. Each sample was contaminated with the microplastics. It's no secret that humanity is faced with a powerful problem of pollution of the planet with the plastic waste. The situation is considered to be critical, since microplastic particles present almost everywhere, including water, air and even food.

A study of five popular seafood products that were purchased specifically from the market for the occasion demonstrated the ubiquity of these micro-pollutants. The researchers bought five wild crabs, ten farmed tiger prawns, ten wild squid, ten farmed oysters and ten wild sardines, and the researchers found traces of plastic in each individual sample.

Franziska Ribeiro from the University of Queensland believes that anyone who loves seafood can eat plastic in it. On an average seafood basis, each person can eat about 0.7 mg of plastic when eating an average serving of oysters, or up to 30 mg of plastic when eating the sardines.

For comparison, 30 mg is the average weight of a grain of rice. The scientists say it is unknown how plastic behaves when it enters the inside body. But after the microplastic content of seafood was first revealed, many manufacturers began to take all measures to prevent plastic waste from entering the artificial cultivation of the various species.

And environmentalists, meanwhile, sounded the alarm, because the insides of the large inhabitants of marine areas washed up on the shore - seals, whales, were clogged with plastic waste. It was plastic that caused the death of 90% of them.

The research results show that the amount of plastic present varies greatly between species and among different individuals of the same species. To determine their calculations, the scientists used a new method of mass spectrometry.

It allows to simultaneously scan five different types of popular plastics. Thus, the researchers found that the samples of squid from the market contain the least amount of microplastics, and sardines do contain the most.
