Polypropylene and its health risks

[secular37]

So Mumsnetters.

For the past two months (!). I have been deliberating which material carpet I should buy for our whole new flat. My heart was set on a beautiful 80/20 wool/nylon carpet but then I read about Moths and I just thought no- I can't risk that.

Then I (unwillingly) looked at polypropylene carpets and found a perfect one- a recycled polypropylene carpet which had that loop style look which I loved the look on wool carpets. However, I am now reading about the health risks of polypropylene (plastics)- including cancer and I do not know what to do?! Should I just settle for the wool carpets and risk moths?

We had wool carpet for 30 years and just changed for 80/20, never seen any moths.

I reckon wool is probably treated in some way?

We have wool throughout.

In my old house, I had deep pile deliciousness everywhere, all so so soft but was no doubt killing me softly.

In the new house we decided to minimise plastics, went for water based nicer paint, natural rugs, carpets and soft furnishings.

I read something about plastics being found in the human brain and other horror stories so I do try to minimise the pesky stuff. I wonder about links to cancer - 'the further away from nature you go, the more in trouble you are' is something that plays on my mind often, especially when I'm trying to make a sensible decision about an item.

In London, moths are everywhere.

It depends if you're also going to reduce toxic cleaning chemicals in your house as well. I cannot abide the smell of most washing powders, hand-wash, shampoo, washing up liquid, air fresheners etc etc so I use ecover or method for cleaning the house/laundry and faith in nature for cleaning myself. Having ditched the petrochemicals years ago it is remarkable how strong the smell of plastic is in other people's houses and on their clothes. Laundry detergent is the worst. I guess people don't realise how toxic it actually smells because they are so inured to it.
