toxic fumes VOC

First time mama here and still learning about everything. I'm currently 37 weeks pregnant and we have 6 air mattress in our hallway closet for guests. I just read that these give off toxic chemicals. The closet is very strong of this smell but never gave any thought of it and the harm that it has on breathing it in. It's a little late now to remove them from the closet but I'm wondering what you ladies think about this and the affect on unborn babies? Will my little one be ok you think or should I be concerned about this?
