Chinese researchers have found that microplastics were widespread in surface waters around the uninhabited coral reefs of the Nansha Islands.

Microplastic pollution is a growing environmental problem in the global oceans, according to the researchers from the South China Sea Institute of Oceanology under the Chinese Academy of Sciences, who investigated microplastic pollution in the waters.

The research article was published in the journal Science of the Total Environment.

They found that the widespread microplastics in the surface waters were predominantly composed of polypropylene and polyethylene, said the paper. More than 70 percent of the microplastics were smaller than three millimeters.

The research showed that the main pollutants like transparent polypropylene and polyethylene fibers may originate from intensive fishing activities near the reefs and the waste discharged by passing merchant ships.

The researchers said the abundance of microplastics found in the surface waters surrounding the target coral reefs was relatively lower than other coral reefs and highly polluted coastal areas of the world. But the microplastic pollution should also be noticed given the importance of coral reef ecosystems.
