in the deep sea huge young form sea squirts swallow plastic particles

recently in the American chemical society annual meeting and remind people to a new study released show, with the "lenses" and so on contact lenses don't throw, lest cause plastic particle pollution of rivers.

Contact lenses are usually made of materials such as silicon hydrogels, which are classified as plastic. The researchers took five commonly available contact lens materials and exposed them to anaerobic and oxygenophilic microbes used in wastewater treatment plants. They then tested them with Raman spectroscopy. They found that after long-term treatment with microorganisms used in sewage treatment plants, the contact lenses physically degrade and eventually form microplastics. These microplastics can be released into the natural environment with treated sewage, where they pose a threat to aquatic life.

Aquatic organisms can mistake microplastics for food, but plastic can't be digested, so this could affect their digestive systems, said Charlie Rolskye of Arizona State University, one of the researchers. Some aquatic life could end up in the human food supply chain, which means humans could be exposed to both the microplastics and the contaminants that cling to their surfaces.
