More than 1.5 billion masks will enter the ocean in 2020

The following is the More than 1.5 billion masks will enter the ocean in 2020 recommended by recordtrend.com. And this article belongs to the classification: Life data.

The global outbreak and popularity of COVID-19 made masks become a daily rigid demand. The one-time characteristics led to an unprecedented huge consumption. On June 8, world ocean day, the impact of discarded masks on the ocean and its creatures is beyond most people’s imagination.

Data show that in 2020, the world will produce about 52 billion masks, of which at least 1.56 billion will flow into the sea due to mismanagement.

The mask seems harmless, but it will absorb and accumulate toxic substances in the sea water. After eating it, marine organisms may block the esophagus and starve to death, or they may slowly die of poisoning. It will take more than 450 years for these masks to degrade completely.

Zheng Yang, a senior engineer of the solid management center of the Ministry of ecological environment, said that the mask is mainly made of plastic, which is composed of polypropylene. It is a non degradable plastic. It is difficult to be digested and absorbed by the biological system in the natural environment, and the degradation time may be decades to hundreds of years.

Compared with other plastics made of petroleum, the fiber diameter of meltblown cloth and non-woven cloth used for masks is extremely small, which will form more micro plastics.

Research shows that the average amount of micro plastic released from unused masks is 71-308 per mask, which will increase to 682-1918 per mask after use.

At present, microplastics have been found in Antarctica and the Mariana Trench in the Pacific Ocean, where human activities are rare. They are easy to be eaten by fish and eventually enter the human body along with the food chain.
