Microplastics – What are they?
Plastic pieces less than 5 millimeters in size are commonly called microplastics. Microplastics are used in manufacturing, industry, and 3D printing. They are in consumer products such as synthetic clothing fabric, toothpaste, and skincare products. They are also formed when plastics break apart into tiny beads.
When microplastics wash down a drain, they are not filtered by wastewater treatment. They spread far across and throughout the ocean. Major sources of microplastics include:
-
Agricultural runoff
-
Aquaculture
-
Cruise ships
-
Ocean dumping
-
Stormwater
-
The shipping and fishing industries
-
Urban runoff
-
Waste management
