Re: New Carpet
Before I was a mom, I did environmental work for 12 years. One of my specializations was indoor contaminants. Your question about new carpet was a common one.
There are no proven dangers of contact with new carpeting. If there are problems, it's because the person has a unique sensitivity to something. I would just watch for rashes or any strange skin irritations. If a rash develops, you'll know. If not, you should be fine.
Once the initial plasticy "new carpet" smell dissipates, the lingering odor in new carpets is formaldahyde. The levels of formaldahyde in building materials is regulated by the feds, and studies have proved the amount of formaldahyde in air is below levels that cause harm. Like I said above, there's always the opportunity for some people to have a sensitivity. A small percentage of people may experience headaches or nausea. A small percentage of that small percentage will complain like the employer intends to kill them. Most people won't experience anything. Again, it's a matter of the individual's tolerance to the chemical.
Just watch for signs of being uncomforaable. You will know.
