Microplastics particles were found in sea salt, indicating that the problem of plastic pollution is becoming more and more serious. Because plastic is difficult to decompose, it is harmful to both land environment and water environment. The particle size of microplastics varies from several microns to several millimeters, and its shapes are diverse, which is difficult to distinguish with the naked eye.

What does it mean to find microplastics particles in sea salt?

The concept of microplastics originated from the paper on plastic fragments in marine water bodies and sediments published by Thompson and others of Plymouth University in the United Kingdom in Science magazine.

Microplastics refers to plastic particles with a diameter less than 5mm. Because plastic is difficult to decompose, after long-term exposure to wind and sun, the volume of plastic gradually becomes smaller, so it becomes microplastics.

Microplastics problem of sea salt is a branch of plastic pollution. To alleviate or solve the microplastics problem of sea salt, it is necessary to reduce the use of plastic bags or find ways to replace plastics, so as to reduce the production of plastics from the source.
