Microplastics are very small pieces of plastic, often too tiny to see easily. They are found in water, soil, and air. These particles come from the breakdown of larger plastic items.

Microplastics have been found in oceans, rivers, and even polar ice. They can come from products like synthetic clothing or worn-down plastic materials. Scientists study their presence in environmental samples.

Microplastics are part of environmental research. They are measured in ecosystems around the world.
