What Are Microplastics?
Microplastics are plastic particles smaller than a grain of rice. They come from larger plastics breaking down or are made small on purpose.
For example, microbeads in beauty products are a type of microplastic. These tiny particles are used in face scrubs, toothpaste, and cleaning products. When washed down the drain, they can end up in rivers and oceans.
Larger plastics, like bottles or bags, also turn into microplastics over time. Sunlight, wind, and water break these items into tiny pieces. This process, called fragmentation, is a major source of microplastics.
Some microplastics are called primary microplastics because they are designed to be small, like the beads in cosmetics or pellets used in manufacturing.
Others, known as secondary microplastics, result from the breakdown of larger plastic items. Both types are harmful and persistent.

Are Microplastics Harmful?
Microplastics pose serious risks to the environment, animals, and humans. Let’s explore why they are harmful:
Harm to Wildlife

Marine animals, such as fish, turtles, and seabirds, often mistake microplastics for food. For example, a study showed that over 90% of seabirds have ingested plastic. These particles can block their digestive systems, leading to starvation or poisoning from harmful chemicals absorbed by the plastics.
These small particles can fill their stomachs, leaving no room for real food. Over time, this can lead to starvation.
Microplastics can also carry harmful chemicals. When animals consume these plastics, they absorb the toxins, which can cause illness or even death. The effects can ripple through ecosystems as predators eat prey that contains these toxins.
Harm to Humans

Although the full impact on human health is still being studied, early research raises concerns. Microplastics have been found in many places. They are in drinking water. They are also in sea salt.
Shockingly, they have even been detected in human blood. The chemicals in plastics may disrupt hormones or damage organs over time.
Inhaling microplastic particles in the air can irritate the lungs, potentially leading to respiratory issues. Microplastics could act as carriers for other pollutants, amplifying their harm to our bodies.

How Do Microplastics Enter the Environment?

Microplastics enter the environment through many sources. Here’s a closer look:
- Littering: Plastic waste left outdoors is exposed to sunlight and weather. Over time, larger pieces break into smaller fragments that spread into soil, rivers, and oceans.
- Washing Clothes: Synthetic fabrics like polyester, nylon, and acrylic shed tiny fibers when washed. These microfibers flow into wastewater systems and eventually reach rivers or seas.
- Car Tires: Each time we drive, the friction between car tires and roads creates tiny particles. These microplastics are washed into storm drains during rain and carried to waterways.
- Industrial Emissions: Factories that manufacture or use plastics can release small particles into the air or water. These emissions are often unregulated and contribute significantly to microplastic pollution.
- Beauty Products: Many cosmetic and cleaning products used to contain microbeads, which are small plastic particles added for exfoliation. While many countries now ban microbeads, their past use has already contributed to environmental pollution.
- Fishing Gear: Abandoned or lost fishing nets, ropes, and other equipment degrade in the ocean over time. These items release microplastics into marine environments.
- Paints and Coatings: The wear and tear of painted surfaces, such as buildings and ships, produces microplastic particles. These tiny flakes are carried into the environment through rainwater or air.
Microplastics travel through the environment in complex ways. Wind can carry them across continents. Rivers act as highways, bringing microplastics from land to sea.
Once in the ocean, currents distribute them worldwide. Microplastics also settle into sediments, creating long-lasting pollution.

Where Do Microplastics Go?

Microplastics are everywhere, spreading through water, air, and soil. Once released, they move through various pathways:
- Oceans: Oceans are the largest sink for microplastics. Rivers carry plastic particles from land, and these accumulate in ocean gyres, forming massive patches of plastic waste. Some sink to the seafloor, affecting marine habitats.
- Soil: Agricultural fields can accumulate microplastics through the use of treated wastewater or plastic mulch. Over time, these particles alter soil structure and may harm beneficial microorganisms.
- Air: Microplastics are lightweight and can travel through the air. They settle on land, water, and even in remote areas like mountains and polar regions. This atmospheric transport spreads microplastics far beyond their sources.
- Food Chain: Microplastics are ingested by small organisms and move up the food chain. Humans who consume seafood, salt, or even drinking water can ingest microplastics as well.
Microplastics’ journey is continuous. They persist in the environment for decades, making it hard to contain their spread.
Why Are Microplastics a Problem?
