Types of Microplastics and Their Properties
⚪Different types of microplastics
➡️Primary microplastics: These are tiny plastic particles that are intentionally produced and used in various products, such as cosmetics, exfoliating scrubs, and cleaning agents.
➡️Secondary microplastics: These are small plastic particles that result from the degradation and breakdown of larger plastic products, such as bottles, bags, and fishing nets.
➡️Nurdles: These are small, lentil-sized pellets that are used as the raw material for plastic products. They can escape from factories during transportation or processing and end up in the environment.
➡️Microfibers: These are tiny strands of plastic that are shed from synthetic textiles during washing or use. They can be found in wastewater and ultimately end up in oceans and other water bodies.
➡️Fragmented microplastics: These are small pieces of plastic that have broken down from larger plastic items, such as bottles or bags, due to physical or chemical processes.
➡️Beads: Small plastic beads are used in certain products such as toothpaste or exfoliating scrubs, to provide texture. These can end up in the environment via wastewater.
➡️Microbeads: Similar to beads, but specifically refers to tiny plastic beads, usually less than 1 mm in diameter, that are used in personal care products such as facial scrubs and body washes.
⚪Properties of microplastics
➡️Size: Microplastics are generally small, with sizes ranging from a few nanometers up to 5 millimeters in length.
➡️Shape: Microplastics can take on a range of shapes, from round beads and pellets to irregularly shaped fragments and fibers.
➡️Composition: Microplastics can be made from a range of different plastic polymers, including polyethylene, polypropylene, polystyrene, and nylon.
➡️Color: Microplastics can come in a range of colors, including white, black, clear, and various shades of blue, green, and red.
➡️Density: The density of microplastics varies depending on their composition and size, but they are generally less dense than water.
➡️Durability: Microplastics can persist in the environment for a long time, as they are resistant to biodegradation and can accumulate in natural systems.
➡️Surface properties: Microplastics can have different surface properties depending on their composition, shape, and exposure to environmental factors such as sunlight, which can cause them to break down and release chemicals.
