According to NY State Department of Health – Exposure to odours could result in health effects ranging from none, to mild discomfort, to more serious symptoms. Some chemicals with strong odours may cause eye, nose, throat or lung irritation. Strong odours may cause some people to feel a burning sensation that leads to coughing, wheezing or other breathing problems. People who smell strong odours may get headaches or feel dizzy or nauseous. If an odour lasts a long time or keeps occurring, it also could affect mood, anxiety and stress level.
