Less than 5 millimeters in size [1], these confounding microparticles are an urgent concern as they invade food chains and slip through purification systems undetected. Microplastics are small plastic fibers and particles that originate from everyday objects. Sources [2] of these microplastics include:
- Clothes
- Paints
- Tire dust
- Plastic litter ( bags, bottles, straws)
- Personal care products (microbeads)
Of the tested tap water worldwide, 83% is polluted with microplastic fibers as small as 1/10th of a millimeter [3]. These fibers are dispersed into the environment through everyday activities such as doing laundry, swimming, walking in the streets, or cleaning your face. These microparticulates then end up in freshwater lakes, rivers, municipal treatment plants, and ultimately tap water. These sources affect not only our oceans, lakes, and springs, but the life of organisms that inhabit them. Figure 1 shows an analysis of microplastics from a sample of ocean water collected from the Pellestrina beach in the Lagoon of Venice. All three particles identified in box B have a size between 5 to 10 μm. The yellow particulates were identified as polypropylene, and the grey particulate was identified as PV23 Hoechst Laser pigment.
