All I seem to do at the moment is write my dissertation. A task I am sure many people have endured. As well as it crucifying a subject I was once interested in, it is all I can think about.
I dream (well…have nightmares) about microplastic pollution. Seriously.
So, because of this, I am venting (I’m sorry) all the annoying little facts about this topic that eat away at my brain, which the public are not informed about…and I wanted an excuse to make a list. You’re welcome:
- Microplastics are generally defined as plastic which is smaller than 5 mm in diameter.
- Microplastics (or microbeads if you prefer) don’t just come from your exfoliators. These products seem to crop up a lot but manufactured (AKA primary) microplastics can also be found in toothpaste, cleaning products like cream cleaner and used for air blasting during manufacturing of everyday items.
- Secondary microplastics are those which have come from a bigger plastic source (not manufactured that size). These can accumulate wherever plastic litter is collected, such as in a landfill or in the sea. They then degrade and become smaller and smaller until they are not visible to the naked eye. In my study, I divided these into three categories: fibres, thin angular pieces and thick angular pieces.
- Washing your clothes results in microplastic pollution. Plymouth University conducted a study which showed that 700,000 synthetic fibres can be released into wastewater, from one use of a domestic washing machine. (So your acrylic and polyester clothes, you’ll struggle to have a 100% cotton wardrobe).
- These microplastics can enter river systems through misconnections. These are when your pipes have been misconnected to lead to the wrong sewer and therefore lead into rivers via outflow pipes. The water which would normally be routed by the foul system to your local waste water treatment works… so think twice about paddling in your local stream on a hot day.
- Once ingested the plastics can then stay in an organism’s stomach, providing no nutrition and taking up room which can lead to starvation. They can also be passed up the food chain to us.
- People aren’t too scared of them because they haven’t caused any significant damage to human health…but it is just a matter of time.
I also thought it would be worth mentioning that yes, I did find microplastics in a local river (Charlton Brook Sheffield) along with a shit load of…well…shit. Look at the picture I’ve included (my own) all the plastics in there are 0.3 mm – 5 mm. Got some big-ass fibres in there (and an exoskeleton which wasn’t dissolved by my concoction of death*). Are these from your clothes? Write a comment and let us know.
