Understanding key terminology helps you navigate microplastics research and testing information more confidently.
- Microplastics range from 1 micrometer to 5 millimeters; nanoplastics are smaller still.
- Common polymer types (PE, PP, PET) have different typical sources and shedding characteristics.
- FTIR analysis and Raman spectroscopy are common laboratory detection methods.
- Understanding this terminology helps you interpret testing results and research more confidently.
Particle Size Categories
“Microplastics” generally refers to plastic particles between 1 micrometer and 5 millimeters; “nanoplastics” refers to even smaller particles below 1 micrometer, requiring more specialized detection methods.
Common Polymer Types
Common plastic polymer types found in household microplastic sources include polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET), each with different common sources and shedding characteristics.
Testing and Detection Terms
“FTIR analysis” and “Raman spectroscopy” are common laboratory methods used to identify and quantify microplastic particles in water or dust samples.
FAQ
What’s the difference between microplastics and nanoplastics?
Microplastics are generally 1 micrometer to 5 millimeters in size; nanoplastics are smaller than 1 micrometer, requiring more specialized detection methods to identify.
