Wellington, Chinese News Agency, September 24th, a research team at the University of Otago in New Zealand found that three-quarters of more than 150 wild fish caught in a certain waters in southern New Zealand contained microplastics in their bodies.

The researchers used microscopes and Raman spectroscopy to study 155 samples of 10 species of commercially important marine fish caught off the coast of Otago for more than a year, and found that 75% of the studied marine fish contained microplastics, with an average of 2.5 microplastic particles were detected, and 99.68% of the identified plastic particles were smaller than 5 mm in size. Microplastic fibers are the most common type.

The study found that fish living at different depths in the above-mentioned sea areas had similar levels of microplastics, suggesting that microplastics are ubiquitous in the seas studied. The researchers say further research is needed to determine the human health and ecological risks of consuming plastic-contaminated fish.

Microplastics generally refer to plastic particles with a particle size of less than 5 mm. More and more evidence shows that microplastics have polluted the marine ecological environment. After these wastes enter the food chain, they will flow back to the human table, endangering human health.

The research results were published in the new issue of the British "Marine Pollution Bulletin".
