Subtitle Forum: What are 4 Poisonous Gases?
The four most common and dangerous poisonous gases are carbon monoxide, sulfur dioxide, nitrogen dioxide, and ozone. Carbon monoxide (CO) is a colorless, odorless gas that can be produced by burning fuel, such as gas, oil, wood, and coal. It is a toxic gas that can cause serious health problems, such as headaches, dizziness, nausea, and even death. Sulfur dioxide (SO2) is a colorless gas that has a strong odor and is produced by burning coal and oil. It is a major contributor to acid rain and is linked to health problems, such as asthma and other respiratory illnesses. Nitrogen dioxide (NO2) is a reddish-brown gas that has a sharp, unpleasant odor. It is created by burning fuel and is a major contributor to air pollution. Ozone (O3) is a colorless gas that has a sweet odor and is naturally present in the upper atmosphere. It is created when sunlight reacts with nitrogen dioxide and other pollutants in the air. Ozone in the lower atmosphere can cause health problems, including eye and respiratory irritation.
