Washing your Clothes: Hygiene or Pollution?

Whether you roll out of bed and slap on whatever you can find laying around, or are a regular attendee of Shopaholics Anonymous, you at one point wear and wash your clothing. Did you know however, that washing your clothes is actually doing more harm than good?

The Problem

For centuries, people have been washing their clothes to rid them of the foul odours and bacteria build up; with the invention of the electric washing machine in the early twentieth century, washing clothes has since become a common household chore.  However, what the masses neglect to realize with every load of laundry they do, is the fact that millions of tiny fibres, known as microplastics, are released into the water ways, which, eventually find their way to the ocean.

Many recent studies have been targeted at investigating the exact amounts of microplastics released each time a load of laundry is washed. One such study showed that an average 13-pound load of laundry can release five-hundred thousand fibres from polyester and close to one million from acrylic-based clothing.  The numbers are shocking.

In fact, one of the worst culprits in polluting the World’s Oceans is the water-repellent raincoat. Chances are, most people have at least one rain jacket hanging in their closet. These jackets are made up of special microplastics known as Perfluorinated Chemicals, or PFCs. They give the raincoat its waterproofing properties but are shed when washed. Once in the oceans, they do not break down. These fibres, which are not visible to the human eye, pose massive threats to, and have adverse effects on marine life. Studies have shown that fish are particularly prone to the effects of microplastics. When they ingest microplastics, it is not passed out as waste. Therefore, they accumulate. Consequently, their digestion is affected, and many organisms do not survive to the age where they can reproduce, destroying entire ecosystems.

The video below shows the the rising threat of such a problem and highlights that immediate action needs to be taken.

What can we do to help?

A practical solution that we can implement in our own lives is making changes to our shopping and washing habits. For instance, instead of buying many cheap basics loaded with synthetic fibres with the expectation that they last a year and then are dumped away, it is better to buy a few quality items that are not composed of as many synthetic fibres. Furthermore, as oppose to washing clothes on a daily basis or in high frequency, it is better to wash them less regularly. Lastly, we can take it upon ourselves to hand wash out clothes and then instead of throwing the water down the drain, where it will end up in the oceans, perhaps use the waste water to water the garden or other agriculture. Simple solutions like this can prevent the shedding of massive amounts of synthetic fibres into the ocean, and reduce the risks faced by marine life.

Save the plastic = Save the life


This video is from National Geographic “How the global ocean plastic pollution problem has become ubiquitous”.

Recently, a catastrophic news “Plastic Garbage Patch Bigger Than Mexico Found in Pacific” published last year has caught public attention. It reported a new finding of a huge region of plastic pollution in South Pacific (near the coastal region of Chile and Peru).

The plastic pollution in the ocean not only means floating bottles or buoys which can be easily discovered but also includes the small pieces of plastic debris which may be invisible. So the ocean cleanup is very difficult. Based on the historical data in 2012, the mean abundance of plastic pollution in South Pacific was roughly 71 kg/km2. What a shocking number it is! The extreme increase of the plastic pollution in South Pacific over the last six years has threatened many marine species and seabirds.

The plastic garbage “patch” includes both big piece (macro-plastics) and very small piece (micro-plastics). In a short-term effect, those seabirds and marine species who accidentally ingested or consumed plastics will stick in their tissues forever (just like the image below). The previous research has shown that mussels ingested micro-plastics through gills would transport to the stomach and digestive glands. In biology classes, we learned that toxins will be accumulated through the food chain and magnified in carnivorous species. As a result, more species will be harmed. Eventually, the whole ecosystem may be negatively impacted.

Right now, the first aid is to clean up the plastic waste in the ocean. This is because the residence time of plastics in the ocean is very long. Also, its degradation time under UV light and water is still uncertain. After breaking into small pieces, micro-plastics will further sink down to the ocean and release toxic chemicals. Although it is a difficult work to clean up all the plastics in the ocean, we still need to try our best to solve the existing garbage. Thus we can prevent further contamination of the marine environment.

Moreover, it is important to increase public awareness of the garbage dumping near coasts. Since most of the containments are anthropogenic, if the general public can get better understandings of the harmfulness of certain behavior, the marine ecosystem will be more sustainable.

In the future studies, scientists should focus more on the problem solving of the ocean plastic pollution, especially appropriate garbage disposal and recycling. Also, an alternative material to plastics that is nontoxic and easily degraded is encouraged to be investigated.
