Introduction to Microplastics
Microplastics are omnipresent, from toys and cosmetics to cleaning products and clothing. They are in the air we breathe, the food we eat, and the water in which we drink and swim. These particles, which are cut off from larger plastic, are suspected to damage reproductive, digestive, and respiratory health, which may lead to infertility, colon cancer, and lung problems.
The Impact of Microplastics
Scientists still determine the effects that these particles, smaller than a rice grain, have on the environment and our body. Therefore, minimizing exposure is so important. Material scientist Joshua Grolman reveals three ways to restrict contact with microplastics at home and work.
Choosing Clothing Carefully
Synthetic clothing – made from materials such as polyester, nylon, and acrylic – is a significant source of microplastic pollution. Fibers are shed during production, wear, and especially when washing. Natural fibers such as cotton, wool, linen, and hemp are derived from plants or animals and biodegradable. This means that they collapse at the end of their life cycle and return to earth. Grolman recommends choosing natural fibers and hanging them to dry instead of using a tumble dryer.
Avoiding Disposable Plastic Products
Ordering takeout or delivery can release microplastics in food, especially if containers are used several times in microwaves or reused. Disposable cutlery is also a main source of microplastic contamination. Grolman avoids these utensils because they are often made from inferior plastics that break slightly or chip. He suggests carrying a titanium or stainless steel utensil set that can be packed away in a shell. He also recommends using a stainless steel water bottle that can be filled in cafés instead of getting a disposable cup.
Reducing Microplastic Exposure from Transportation
Car tires, especially those with heavier vehicles, create a lot of microplastics when wearing from everyday use. Grolman prefers to commute by bike. He notes that a widespread misunderstanding is that cycling on the outside exposes more pollution than being in a car. However, if you are in traffic, the air intake of your car is right next to the rear tube of the car in front of you and normally low to the street, on the tire abrasion. Other advantages of cycling are increased physical activity, fuel savings, and a lower CO2 footprint. While it may not be practical to ride a bike, Grolman recommends being open to alternatives to cars and trying to limit the time spent on streets with strong car traffic.
