I went over to my parents house today, after ten minutes of being there, I noticed that they were burning something in their burning barrel. I asked is there plastic in there , and they said, maybe some, I think there was a binder with some plastic inserts in there . I am panicking now, because I am 5 weeks pregnant, and I am afraid that I hailing those fumes for 10-15 minutes may harm my baby, or hinder their development! (I don t know what else was in the barrel at the time, but I made sure to leave the area asap, once I realized!)
