Recently I have spent more time reading about Radon, VOC, and products that contain harmful ingredients. If you try to eat more eco-product also take a look at the stuff that surrounds you. Inside our homes many if not all the surfaces release compounds in the air that are not necessarily good for our health. The first step would be to limit the toxic materials or use them as sparingly as possible and if the space allows for a mechanical ventilation system I would suggest you look into it, as it is a very good way of reducing the concentrations of pollutants to low levels.
If what you eat matters this should matter as well.
Most if not all of the products that are made out of plastic and have a rubbery/soft texture contain harmful chemicals that enter our bodys. The easiest method for these substances to enter our body is licking/chewing (sounds funny but many children chew on erasers/pencil etc), but there are other ways and a lot more products that we use daily.
Moving on to the stationary... I have come across an article, China Testing School Erasers
You can read more in the article. Long story short, they have tested for products meeting the toxic materials present in the erasers and the concentrations.
The brands that were part of the test wee:
The complete report is in Chinese, so I can't understand more than the pictures tell me.
Tombow Mono Plastic Eraser, Muji Plastic Eraser, Uni Plastic, Pilot Foam, Radar, Pentel Hi-Polymer, Faber Castell Dust Free plus many more use PVC in their composition. Some have really high values, but I will not try to interpret those. The highest numbers are beside UNI, Pilot, Radar, MONO.
The article recommends using PVC free.
So here I am, testing three Faber Castell erasers, not for toxic materials but on their performance in doing their job. Two of them are PVC Free Erasers (the top row erasers from the first picture) and the third is the Faber Castell Dust Free eraser.
The Dust Free 18 71 21 is a very good eraser, praised by a lot of people and widely used. It erases ok, and leaves very little residue behind. This makes it a favorite. Also, the black color helps to hide the dirt accumulated on it. This will be the control, representing the PVC erasers.
The white PVC Free eraser came with a protective paper cover while the green PVC Free eraser came in a very basic plastic wrap. The white PVC Free has all the writing on the paper cover, while the green has the information printed directly on it.
The Dust Free is grippy in a nice way, not wrinkles in the paper grippy, and it flexes a lot, leaving little to no residue behind.
The white eraser leaves a little more residue compared with the Dust Free, but still, small quantities compared with other erasers. The residue tends to clump together but there are definitely a lot of small particles.
The Pvc Free green eraser seems to be a bit stiffer than the white Pvc Free. You can feel it in hand and when you use it. It has a plastic feel, sliding over the paper more. It leaves more residue but the residue tends to stick to the eraser (or not break off).
In conclusion, I would say get a PVC Free eraser. It won't be a huge difference in erasing performance.
I am sure that PVC erasers will not cause that much harm, compared to other pollutants we encounter daily but it is good to limit as much as possible your exposure to them.
