Where do microplastics come from in everyday products?

published on 05 March 2024

Microplastics are tiny plastic particles found in a variety of everyday products, and they pose a growing concern for our health and the environment. Here's a quick overview of where they come from and what we can do about it:

  • Primary Microplastics: These are intentionally small plastics found in personal care products (like microbeads in face scrubs), synthetic clothing fibers, and industrial pellets.
  • Secondary Microplastics: These originate from the breakdown of larger plastic items such as bottles, bags, and fishing gear.
  • Common Sources: Daily items like toothpaste, cosmetics, synthetic clothes, and kitchenware can release microplastics into our environment.
  • Environmental and Health Impact: Microplastics can end up in our bodies through consumption or inhalation, potentially leading to health issues.
  • Solutions: Opting for plastic-free alternatives, participating in initiatives like Plastic-Free July, and supporting eco-friendly companies can help reduce microplastic pollution.

Understanding the sources and impacts of microplastics is crucial. Making informed choices about the products we use can significantly reduce our plastic footprint and protect our health and the planet.

Defining Primary vs. Secondary Microplastics

Primary microplastics are tiny plastic bits made on purpose to be small. They're in stuff like face scrubs, toothpaste, and cleaners. Examples include:

  • Microbeads - small plastic balls in personal care products to help scrub your skin
  • Microfibers - tiny plastic threads from clothes made of synthetic materials that come off when you wash them
  • Plastic resin pellets - little plastic beads used to make other plastic products

Secondary microplastics are pieces that used to be part of bigger plastic items but broke down into smaller bits. This can happen when plastic bottles, bags, or other items get worn out by the sun, water, or just by being old. Things like fishing gear and packaging materials can also break down into these tiny plastic particles.

So, primary microplastics are made small on purpose, and secondary microplastics are big plastics that have broken down into smaller pieces.

Exposure Pathways into Bodies and Environment

When we use products with primary microplastics and wash them away, they end up in our water systems. Most places that clean our water can't catch these tiny bits, so they get into rivers, lakes, and oceans. Microplastics can also get into nature from littering and spills.

In water, tiny creatures and fish eat microplastics, and then bigger animals eat them. This way, microplastics move up the food chain.

Humans can get microplastics in them by:

  • Drinking water that's got microplastics in it
  • Eating fish and seafood that's eaten microplastics
  • Breathing in dust at home or work that has microfibers from clothes
  • Breathing in air outside that has microplastics floating around

Microplastics are so small they can get into our blood and even inside cells.

Scientific Research on Health and Environmental Impacts

Studies show microplastics can cause problems like inflammation and tumors in animals and might mess with our cells and hormones. In the ocean, microplastics can hurt the growth and health of sea creatures, carry diseases, leak harmful chemicals, and cause animals to get tangled or starve.

We're still learning about how bad microplastics are for us and the environment. But it's clear we need to stop adding more microplastics to our products. We also need more research, rules, education, and new ways to deal with this plastic pollution problem.

Everyday Sources of Microplastic Pollution

Personal Care and Cosmetics

Lots of beauty items like face scrubs, toothpaste, and shampoo have tiny plastic beads in them. These beads are meant to help clean or scrub your skin, but they're so small that they don't get caught in the systems that clean our water. Instead, they end up in rivers, lakes, and the ocean. Fish and other sea animals might eat these plastics, which can then end up in the food we eat.

Other common sources:

  • Sunscreens that wash off in the ocean
  • Makeup with tiny plastic particles for shine or color
  • Products with plastic packaging that breaks down over time

Household and Kitchen Items

Things we use in the kitchen, like plastic wrap, storage containers, and plastic utensils, can break down into tiny plastic pieces. This happens when they get washed and used over time. These small bits can then wash down the drain.

Examples include:

  • Plastic wrap and bags
  • Plastic food containers
  • Plastic plates, cups, and utensils

Cleaning tools and dish scrubs made of plastic also shed tiny fibers when we wash them.

Textiles and Fabrics

A lot of our clothes are made from materials like polyester and nylon. When we wash these clothes, thousands of tiny plastic threads come off and go down the drain. These threads are too tiny to be caught and removed by the machines that clean our water, so they end up in nature.

Recreational Equipment and Products

Things we use for fun, like fishing lines and plastic playgrounds, wear down over time. This wear and tear breaks them down into tiny plastic bits. Even car tires lose tiny bits of rubber when they rub against the road. Rain can wash these plastics into the ground and water.

All these small pieces of plastic can end up in the soil and water, where they break down even more. This is how microplastics from our everyday lives can pollute the environment.

Solutions for Reducing Microplastic Pollution

In this part, we'll talk about ways you can use less plastic and suggest safer options that don't have microplastics.

Plastic-Free July

Plastic-Free July is a challenge to not use plastic for the month of July. It helps you use less plastic and tells others about the problem of plastic waste.

The website for Plastic-Free July has tools like guides, a list of shops, and a group for support to help you stop using single-use plastics for 31 days. They also give advice if you find it hard to give up all plastic in July. Even a small cut in plastic use during July can help a lot.

Everyday Swaps

You can make easy changes every day to use less plastic:

  • Use metal or glass straws instead of plastic ones
  • Carry reusable bags instead of using plastic bags
  • Choose natural loofahs over plastic scrubbers
  • Store food in glass containers instead of plastic ones

Start with one change and stick with it before trying another. Step by step, these changes can lead to using a lot less plastic.

Eco-Friendly Alternatives

Some companies are making things without plastic or that can break down naturally:

Choosing these options helps make more sustainable materials and products while keeping plastic waste out of the ocean and off the land.


Conclusion and Final Thoughts

Microplastics are tiny bits of plastic that are a big problem, and it all starts with the choices we make when we shop. The more we know about what's in our products and how they're made, the more we can help change things by choosing better options. Companies also need to do their part by finding new ways to package things without so much plastic.

Here's what you need to remember:

  • Microplastics come from really small plastic beads and fibers on purpose, as well as from bigger pieces of plastic that break down. We find them in everyday stuff like beauty products, clothes, things we use in the kitchen, and sports gear.
  • These tiny plastic bits can get inside us by eating, breathing, or touching things that have them. There's some worry they might be bad for our health and the environment, but we need more research to be sure.
  • You can make easy changes like using reusable bags instead of plastic ones, or joining challenges like Plastic Free July. Looking for products from companies that care about the environment can also make a big difference.
  • Companies should think about how they make and package their products to use less plastic. This could mean using materials that come from plants or have been recycled. Everyone has a role to play in cutting down on microplastic pollution by being careful and speaking up for what's right.

Microplastics are so small they can end up everywhere, causing problems for the whole planet. But if we all do our part, whether it's making smarter choices at the store or companies getting creative with how they package things, we can make the world cleaner and safer for everyone.

Where are microplastics used in everyday life?

Microplastics are tiny plastic pieces found in a lot of things we use every day:

  • Toothpaste - They help clean your teeth better.
  • Lip products - They make these products stick together well.
  • Mascara - This makeup often has microplastics in it.
  • Nail polish - They make the polish last longer.
  • Facial scrubs - They help remove dead skin.
  • Cleaning supplies - They’re added to help with cleaning.
  • Synthetic clothing - Clothes made from man-made fabrics let go of tiny plastic bits when washed.

So, we’re surrounded by microplastics without always knowing it.

What is the most common source of microplastics?

The biggest source of microplastics comes from clothes made of synthetic materials like polyester and nylon. About 35% of all the microplastics in the oceans are from these materials. When we wash our clothes, they release tiny plastic particles.

What common household items are microplastics found in?

You can find microplastics in many things around the house:

  • Cans of soda or beer have a plastic lining.
  • Bottled drinks.
  • Synthetic clothes and fabrics.
  • Plastic salt grinders.
  • Sunscreens and makeup.
  • Cleaning products with tiny plastic beads.
  • Plastic containers and wraps.

Knowing about all the places microplastics hide helps us make better choices.

What products have the most microplastics?

Some items create a lot of microplastics:

  • Plastic bottles and packaging.
  • Plastic bags and wraps.
  • Clothes made from man-made fabrics.
  • Car tires - they lose tiny bits of rubber because of friction with the road.
  • Fishing nets and gear - they break down into microplastics over time.

Choosing wisely and pushing for better products can help reduce the amount of microplastics.
