Is sleeping against concrete walls that is dusting slightly, a risk for silica dust inhalation?

[celleste]

In my flat, I have 2 internal concrete walls, one where I sleep against every night

Im worried that I am exposing myself to silica dust or another contaminants that may come from concrete

Im really not sure how much the concrete has been sealed and how much dust is coming from it

Its obviously solid and not crumbling, but when i rub the concrete, its slightly chalky on my hand. Its also not glossy or smooth suggesting it hasn't been completely sealed?Â

I can see some dust on the ledge below the wall, but dont know how much of this is household dust

What do you think? Is there any risk?

Ive added some inflation below, if that helps

 

Thanks in advance!

 

NB: Regarding regulations, Im not in US, but NZ, so not sure regulations here. Flat was built in 2017

Great question and not sure.  It looks very cool.  I would image you can wipe it clean then seal to keep the beauty in tact and also protect yourself.  I know a lot of people use concrete countertops so I am sure there is a way.
